Strossmayer u Osijeku, Odijel za biologiju Modul: Povrćarstvo i cvjećarstvo (VI semestar - izborni modul) Cvijeće je od davnina bogatstvom svojih oblika, mirisa i boja privlačilo pažnju čovjeka. Svojom je ljepotom poticalo njegovu maštu i na razne mu načine upotpunjavalo život. Mnoge su legende vezane uz cvijeće i kroz povijest pripisivana su mu svakojaka značenja i simbolika. Jezik cvijeća, nazivan još i floriografija, u viktorijansko je doba smatran idealnim sredstvom komunikacije za diskretno izražavanje osjećaja. Na prijelazu iz 19. u 20. stoljeće u nekim se zemljama poznavanje jezika cvijeća smatralo dijelom opće naobrazbe. Iako nema čvrstih pravila, a ona koja postoje razlikuju se od podneblja do podneblja, cvijeće i cvjetne boje još i danas nose poruke i uz njih vežemo određene osjećaje. Pravi ljubitelji prirode i njezine ljepote rijetko će ostati ravnodušni na ljepotu kojom odiše svaki cvijet. Tih nekoliko latica i prašnika, priroda vješto oblikuje na bezbroj načina i time nam pruža veliko zadovoljstvo. Najbolje to znaju brojni ljubitelji cvijeća koji umiju tražiti i promatrati ljepotu u njihovoj građi, boji ili mirisu i samo jedan cvijet u vazi ili na prozorskoj dasci može uljepšat životni prostor i dati mu toplinu (Ivančić, 2009. ). Slika. Dalia (Dahlia) Slika. Božićna zvijezda (Euphorbia plucherrima) (foto Parađiković N.) Švedski botaničar osamnaestog stoljeća, Carla Linneausa (1707-1778.) je utemeljio binominalni sustav. U djelima Geneva plantarum i Species plantarum, Linnaeus je razvrstao svaku biljku koristeći dvije riječi u latinskom jeziku. Prva riječ bila je naziv roda (npr. Ilex), a druga pridjev (npr. aquifolium). Zajedno su osigurale naziv po kojem se mogla prepoznati biljka (Ilex aquifolium, božikovina). Ostalim vrstama istoga roda dani su različiti pridjevi Ilex crenata, Ilex pernyi, Ilex serrata itd. Biljke su grupirane u određene porodice prema strukturi cvjetova, plodova i ostalih organa. To znači da se porodica može sastojati od izrazito srodnih i specijaliziranih biljaka kao što su orhideje (porodica Orchidaceae) i bromelije (Bromeliaceae) ili obuhvaća biljke prema različitosti (prema onome što nude vrtlaru) kao što su one iz porodice Rosaceae: Alchemilla, Cotoneaster, Crataegus, Geum, Malus, Prunus, Pyracantha, Sorbus i Spiraea. Naziv može odavati počasti: naziv Fuchsia je u čast Leonharta Fuchsa, njemačkog liječnika i herbalista. Može nam govoriti odakle biljka dolazi, kao vrsta Parrotia persica (iz Perzije, današnjeg Irana). Biljka može nositi naziv prema skupljaču koji ju je uveo: vrstu Primula forrestii u uzgoj je doveo George Forrest. Ili, naziv nam može govoriti nešto o fizičkim značajkama: Pelargonium izvedeno je od grčke riječi pelargos (roda) - što je prikladan opis plodova te biljke, koji nalikuju kljunovima roda; quinquefolia, pridjev vrste Parthenocissus quinquefolia znači da se listovi sastoje od pet liski, od latinske riječi quinque (pet) i folium (list). (Coombes, A., 2006.). Slika. Carl Linneausa (1707-1778.) Slika. Ilex aquifolium – božikovina (www.linnaeus.uu.se) (http://en.wikipedia.org/wiki/Ilex_aquifolium) Cvijet je generativni biljni organ biljke i služi za razmnožavanje i produžetak vrste, a koji se sastoji od cvjetne stapke, cvjetišta, ocvijeća, tučka i prašnika (Hazler - Prilepić, 2005.). Većina cvjetova oprašuje se kukcima koji, skupljajući pelud, raznose njegova zrnca od cvijeta do cvijeta. Na taj način omogućavaju oplodnju biljaka. Nakon oplodnje, plodnica cvijeta zadebljava i stvara plod sa sjemenkama, a tijekom njezina debljanja sa cvijeta otpadaju svi dijelovi čija je uloga već završena. Zreli plod sadržava zrele i klijave sjemenke od kojih će nakon sjetve nastati nove biljke iste vrste. Ocvijeće može biti: 1 - jednostavno ocvijeće, perigon, je građeno od istovrsnih elemenata, listova ocvijeća - tepala. Listovi ocvijeća često se oblikom i bojom razlikuju od pravih listova, mogu biti nalik laticama te se ocvijeće naziva korolinično (corola - vjenčić), ili lapovima te se naziva kalicinično (calyx - čaška). 2 - dvostruko ocvijeće, periant, građeno je od dvaju različitih tipova listova, lapova koji tvore čašku i latica koje tvore vjenčić. Latice mogu stajati slobodno na cvjetištu - horipetalno ocvijeće ili latice mogu međusobno srasti - simpetalno ocvijeće. Srasti međusobno mogu i lapovi. Tučak se sastoji od plodnice, vrata i njuške. Plodnica je nastala sraštavanjem jednog ili više plodničkih listova. Svi plodnički listovi jednog cvijeta čine ginecej. Apokarpna plodnica nastala je sraštavanjem samo jednog plodničkog lista, a cenokarpna sraštavanjem dva ili više plodničkih listova, stvaranjem pregrada (sinkarpna) ili bez pregrada (parakarpna). U odnosu na cvjetište, plodnica može biti nadrasla (simbol u cvjetnoj formuli G(n), n je broj plodničkih listova - smještena je na vrhu cvjetišta, podrasla (G(n)) - plodnica je smještena u udubljenom cvjetištu i s njime je srasla, obrasla (G -(n)-) - plodnica je smještena u udubljenom cvjetištu, no nije s njime srasla. U plodnici se nalazi jedan ili više sjemenih zametaka, u svakom je embrionska vrećica sa 8 stanica. Prašnici su građeni od prašničke niti koja nosi prašnicu sastavljenu od dviju poluprašnica povezanih konektivom. Svaka poluprašnica ima dvije polenovnice u kojima se stvara polen (sa 3 stanice polenove mješinice). U nekih vrsta prašnici mogu međusobno srasti s prašnicama ili prašničkim nitima, ili mogu srasti s ostalim dijelovima cvijeta, najčešće vjenčićem. U cvijetu je skrivena reducirana spolna generacija, gametofit. U embrionskoj vreći (makrospori) 3 stanice jajnog aparata od kojih je jedna jajna stanica, 2 sinergide i 3 antipode predstavljaju ženski gametofit, dok je muški gametofit 9 skriven u peludnim zrncima (mikrosporama), a građen je od vegetativne i generativne stanice (generativna se stanica tijekom klijanja polenove mješinice podijeli u 2 spermalne stanice). Plod Plod je organ za rasprostiranje koji se razvija nakon dvostruke oplodnje, a sastoji se od usplođa i sjemenke. Sjemenka se sastoji od klice, endosperma i sjemene lupine. Klica nastaje oplodnjom jajne stanice, a hranjivo staničje, endosperm oplodnjom sekundarnih jezgara. Klica i endosperm obavijeni su zaštitnom sjemenom lupinom koja nastaje od integumenata. Usplođe se sastoji od eksokarpa, mezokarpa i endokarpa. Ako se usplođe razvija iz plodnice - plod je pravi. Kod nepravog se ploda usplođe razvija i od drugih dijelova cvijeta (npr. cvjetišta). Plodove dijelimo na osnovi nekoliko kriterija. Pododjeljak Magnoliophytina, kritosjemenjače, dijelimo u 2 razreda 1 - Magnoliatae - dvosupnice 2 - Liliatae – jednosupnice Svaki se razred dijeli u podrazrede, ovi u nadredove, nadredovi u redove, a ovi u porodice. Magnoliatae, dvosupnice Biljke ovog razreda imaju najčešće 2 supke, razvijen dugovječni glavni korijen iz kojeg izbija slabije razvijeno bočno korijenje. Provodne žile su na presjeku stabljike poredane u krug i one su, osim u jednogodišnjica, otvorenog tipa što omogućuje sekundarni rast u debljinu. Listovi su različitog oblika, često razdijeljeni, peraste ili mrežaste nervature. Ocvijeće je dvostruko, a cvjetovi su građeni na osnovi broja 5 ili 4 (pentamerni ili tetramerni), no broj plodničkih listova je često manji (1 ili 2), a često odstupa i broj prašnika (redukcija ili sekundarna poliandrija). Magnoliaceae, Ranunculaceae, Papaveraceae, Rosaceae, Fabacea, Rutaceae, Rhamnaceae, Apiaceae, Brassicaceae, Malvaceae, Primulaceae, Caprifoliaceae, Asteraceae, Lamiaceae, Apocynaceae,Valerianaceae, Boraginaceae, Scrophulariaceae, Caryophyllaceae. Liliatae, jednosupnice U biljaka ovog razreda postoji jedna supka. Glavni korijen vrlo brzo prestaje s rastom, a iz njega izbija adventivno korijenje. Provodne žile stabljike su zatvorenog tipa, a na presjeku nisu poredane u krug. Listovi su najčešće sjedeći, paralelne nervature. Ocvijeće je perigon, a cvjetovi su građeni na osnovi broja 3 (trimeran cvijet). Liliaceae, Iridaceae, Poaceae, Orchidaceae. Literatura: Sambamurty, A. V. S. S (2005): Taxonomy of Angiosperms. I.K.

    65 Possibly Lost Orchid Treasure of Bangladesh

    J. biodivers. conserv. bioresour. manag. 3(1), 2017 POSSIBLY LOST ORCHID TREASURE OF BANGLADESH AND THEIR ENUMERATION WITH CONSERVATION STATUS Rashid, M. E., M. A. Rahman and M. K. Huda Department of Botany, University of Chittagong, Chittagong 4331, Bangladesh Abstract The study aimed at determining the status of occurrence of the orchid treasure of Bangladesh for providing data for Planning National Conservation Strategy and Development of Conservation Management. 54 orchid species are assessed to be presumably lost from the flora of Bangladesh due to environmental degradation and ecosystem depletion. The assessment of their status of occurrence was made based on long term field investigation, collection and identification of orchid taxa; examination and identification of herbarium specimens preserved at CAL, E, K, DACB, DUSH, BFRIH,BCSIRH, HCU; and survey of relevant upto date floristic literature. These species had been recorded from the present Bangladesh territory for more than 50 to 100 years ago, since then no further report of occurrence or collection from elsewhere in Bangladesh is available and could not be located to their recorded localities through field investigations. Of these, 29 species were epiphytic in nature and 25 terrestrial. More than 41% of these taxa are economically very important for their potential medicinal and ornamental values. Enumeration of these orchid taxa is provided with updated nomenclature, bangla name(s) and short annotation with data on habitats, phenology, potential values, recorded locality, global distribution conservation status and list of specimens available in different herbaria. Key words: Orchid species, lost treasure, Bangladesh, conservation status, assessment. INTRODUCTION The orchid species belonging to the family Orchidaceae are represented mostly in the tropical parts of the world by 880 genera and about 26567 species (Cai et al.

In nature, orchid seed germination is obligatory following infection by mycorrhizal fungi, which supplies the developing embryo with water, carbohydrates, vitamins, and minerals, causing the seeds to germinate relatively slowly and at a low germination rate. ,e nonsymbiotic germination of orchid seeds found in 1922 is applicable to in vitro propagation. ,e success of seed germination in vitro is influenced by supplementation with organic compounds. Here, we review the scientific literature in terms of the contents and role of organic supplements in promoting seed germination, protocorm development, and seedling growth in orchids. We systematically collected information from scientific literature databases including Scopus, Google Scholar, and ProQuest, as well as published books and conference proceedings. Various organic compounds, i.e., coconut water (CW), peptone (P), banana homogenate (BH), potato homogenate (PH), chitosan (CHT), tomato juice (TJ), and yeast extract (YE), can promote seed germination and growth and development of various orchids.

  • An Enumeration to the Orchids and Their Conservation Status in Greater Sylhet, Bangladesh

    An Enumeration to the Orchids and Their Conservation Status in Greater Sylhet, Bangladesh

    Bangladesh J. Plant Taxon. 23(1): 13-25, 2016 (June) © 2016 Bangladesh Association of Plant Taxonomists AN ENUMERATION TO THE ORCHIDS AND THEIR CONSERVATION STATUS IN GREATER SYLHET, BANGLADESH M.M. ISLAM, M.K. HUDA1 AND M. HALIM2 Department of Botany, University of Chittagong, Chittagong 4331, Bangladesh Keywords: Conservation; Diversity; Orchidaceae; Sylhet. Abstract The present investigation deals with enumeration including diversity, ecology and conservation of the family Orchidaceae of greater Sylhet region of Bangladesh. Extensive field trips were made at 11 different sites of this region during early monsoon, late monsoon and winter seasons. Relevant literature and different herbaria were consulted to gather information about the orchids of this region. Orchidaceae is represented in greater Sylhet by 75 species under 49 genera. Out of these, 25 species are terrestrial, 48 are epiphytic, one is saprohytic and one is hemiepiphytic. Presence of 37 monotypic genera indicates a narrow diversity in Orchidaceae of this area. The present investigation revealed that 26 orchid species are restricted and distributed only in Sylhet region in Bangladesh. The currently accepted taxonomic nomenclature, synonyms, habit, flowering time, present conservation status and geographical distribution are provided under each taxon. Introduction Orchidaceae is one of the largest flowering plant families, represented by about 1000 genera and 20,000 species with cosmopolitan distribution, primarily in the tropics and rarely in arctic regions (Chowdhery, 1998). A preliminary checklist of family Orchidaceae for Bangladesh was made by Huda et al. (1999) with an enumeration of 160 species and 2 varieties under 63 genera for Bangladesh. Of them, 106 taxa were epiphytic and remaining 56 were terrestrial.

  • Modificaciones En Medios De Cultivo Aplicadas En Conservación Y Producción In-Vitro De Orquídeas

    Modificaciones en medios de cultivo aplicadas en conservación y producción in-vitro de orquídeas Modifications in cultivation media applied in preservation and in-vitro production of orchids Juan Manuel Salgado1, Laura Peñaranda2 Recibo: 10.05.2018 Aceptado: 27.03.2019 Salgado, J. y Peñaranda, L. (2018). Modificaciones en medios de cultivo aplicadas en conservación y producción in-vitro de orquídeas. Revista Colombiana de Investigaciones Agroindustriales. 6(1), 17-28. Las orquidáceas son una familia de plantas con interés económico y científico dada su diversidad ornamental y aplicaciones en la medicina entre otras. Sin embargo, muchas especies de orquídeas están amenazadas y en peligro de extensión, debido a la transformación del hábitat y la extracción excesiva de especies con interés comercial. Aunado a esto, su propagación y conservación in vitro, resulta costosa, debido a la complejidad biológica. El presente estudio reporta información sobre un medio de cultivo versátil, enfocado en la conservación de germoplasma y producción in-vitro de orquídeas. Para ello se diseñó una formulación basada en la modificación del medio Murashige y Skoog (1962) con vitaminas Morel, agua de coco y carbón activado recurriendo a la combinación de experiencias exitosas de la bibliografía reportada. Se recolectaron en el eje cafetero, cápsulas de Prosthechea fragrans (Sw.) W.E.Higgins y esterilizadas en el laboratorio. Los medios de cultivo fueron probados para la inducción de callo, proliferación de estructuras tipo protocormos, desarrollo y mantenimiento de plántulas. Se logró la germinación asimbiótica in- Resumen vitro de las de semillas colectadas, se obtuvieron tres tipos de callos. Luego de 7 meses de cultivo, las plántulas alcanzaron entre 1,1.

    Paphiopedilum Species 2010 -2016

    The “New” Paphiopedilum species 2010 -2016 Introduction As is often the case in the world of Orchidaceae, there can be substantial disagreement between taxonomists about the classification of orchids. This is certainly the case for Paphiopedilum, and in the context of the discussion topic “newly discovered” Paphiopedilum species, often there are more questions than answers about whether they are in fact new, are forms of existing species, synonymous with existing species or in there classification is invalid. Given the differing and often opposing views of many of the recognised authors including Dr Guido Braem, Dr Phillip Cribb, the late Dr Jack Fowlie, Olaf Gruss, Holger Perner and Dr Tanaka to name but a few, accessing definitive authority for newly recognised species has proven difficult. For the purposes of this exercise, the Plant List supported by Kew and several leading herbaria, http://www.theplantlist.org/1.1/browse/A/Orchidaceae/Paphiopedilum/ has been used as a quick reference as it provides details of those Paphiopedilum species where the identification is accepted, as well as those unresolved or in dispute. Dr Tanaka who is recognised as a very knowledgeable enthusiast has a long list of “new” species on his webpage http://www.orchid.or.jp/orchid/people/tanaka/indexe.html He says very clearly that his page is not for scientists or botanists, but is for enthusiasts, thereby avoiding the classification disputes that plague taxonomy. For the purposes of this paper, I will use species that Dt Tanaka lists as “new” as a basis for informing members about newly discovered Paphiopedilum and improving our knowledge and understanding of the taxonomical processes involved in validly identifying and obtaining recognition for a previously unidentified plant species.
