Ir. Sutami no 36A, Surakarta 57126, Indonesia Received : 5 August 2009 Accepted: 27 August 2009 Abstract To study the intergeneric crossing between orchids of Phalaenopsis sp. and Vanda tricolor, three species of Phalaenopsis sp. (Phalaenopsis Joane Kileup June, Phalaenopsis Pinlong Cinderella, and (Phal. Fortune Buddha x Phal. Princess Kaiulani) were crossed reciprocally with Vanda tricolor in time-different value (within the first, second and third week after full opened flower). The crossing of Phalaenopsis sp. and Vanda tricolor was compatible, and the use of Phalaenopsis sp. as male parent had better probability in producing fruits rather than the opposite. The crossing which was done at the first and the second weeks after blooming produced more fruit than the crossing at the third week after blooming, even though it did not affect the success of crossing, time of fruit formation, and duration of fruit hanging. Key words: Intergeneric Crossing, Orchids, Phalaenopsis sp., Vanda tricolor INTRODUCTION One strategy to make a new-hybrid compatible to Doritis pulcherrima var. cultivars of orchids is by crossing between the Champornensis (Hartati, unpublished results). orchid-parents having different characters. To assess the effect of time of crossing (week Orchid hobbyist usually prever to collect after blooming) in order to make new hybrid hybrid resulted from crossing orchids, orchids with more attractive flower characters because the hybrided orchids have more to the fruit formation in, Phalaenopsis sp. and various colour, pattern, size, shape of flower Vanda tricolor was intergeneric crossed. and more likely to have longer life of flower (1). Therefore it is beneficial to create a new hybrid by crossing one species to another.

  • Traditional Therapeutic Uses of Some Indigenous Orchids of Bangladesh
    ® Medicinal and Aromatic Plant Science and Biotechnology ©2009 Global Science Books Traditional Therapeutic Uses of Some Indigenous Orchids of Bangladesh Mohammad Musharof Hossain* Department of Botany, University of Chittagong, Chittagong-4331, Bangladesh Correspondence : * [email protected] ABSTRACT The traditional therapeutic uses of some indigenous orchids of Bangladesh are described in this paper. Terrestrial (11) and epiphytic (18) orchids, 29 in total, are used by Bangladeshi rural and tribal people for the treatment of nearly 45 different diseases and ailments. Roots, tubers, pseudobulbs, stems, leaves and even whole plants are used. Some herbal preparations have miraculous curative properties. Unfortunately, these preparations have not typically been subjected to the precise scientific clarification and standardization which are consequently required for clinical implementations. Some of the orchids are endangered due to over-exploitation and habitat destruction. Conservation strategies for orchids and further pharmacological studies on traditional medicines are suggested. _____________________________________________________________________________________________________________ Keywords: astavarga, conservation, ethnomedicine, herbal remedies, rasna INTRODUCTION the underground tuber of Orchis latifolia is used in the drug ‘munjatak’ pacifying cough (Khasim and Rao 1999).

  • Phalaenopsis
    Chapter 23 Phalaenopsis Chia-Chi Hsu, Hong-Hwa Chen, and Wen-Huei Chen Abstract Phalaenopsis is one of the most popular cultivated orchids worldwide. So far, 92 native species and 34,112 hybrids of Phalaenopsis have been registered in the Royal Horticultural Society (RHS), but only 18 native species are frequently used for breeding. In Phalaenopsis market, large flowers with various colors are most popular. Phal. amabilis and Phal. aphrodite are the major species used for breeding the white-and-large-flower hybrids. The colored hybrids include pink, red- to- purple, green, yellow-to-orange, and black colors, as well as distinct colors in tepals with red lip. For large-and-red flowers,Phal. schilleriana and Phal. sanderiana are the major parent species, whereas Phal. equestris and Phal. pulcherrima are important for the development of the small- and medium-sized red flowers. Members of the subgenusPolychilos are the most important ancestors for yellow-to-orange flowers. More recently, there is an increased interest in plants with white, pink, or yellow colors with red stripes and/or spots. These traits are introduced from Phal. lindenii, Phal. stuartiana, and Phal. amboinensis. Furthermore, harlequin flowers which have clown-like spots and very complicated color patterns are released in the market, as well as hybrids with peloric and Bigfoot flowers. Besides color, scent and (a)biotic stress resistance are becoming important targets in Phalaenopsis breeding. Keywords Bigfoot · Breeding · Harlequin · Orchids · Peloric · Phalaenopsis C.-C.

  • Orchitheek 1 Uitgave: Nederlandse Orchideeën Vereniging
    Nederlandse Orchideeën Vereniging – Orchitheek 1 Uitgave: Nederlandse Orchideeën Vereniging. Auteursrechten voorbehouden Phalaenopsis hieroglyphica Rchb.f. Sectie Zebrinae Syn. Phalaenopsis lueddemanniana ssp. Hieroglyphica Deze plant werd gevonden door P. Micholitz in het jaar 1890 op de zuidelijke eilanden van de Filippijnen in het Sulu-gebied, en werd overgebracht naar de Fa. Low en Co in Engeland. Ze werd door F. Reichenbach beschreven en gepubliceerd in de Gardeners’ Chronicle als Ph.lueddemanniana ssp. hieroglyphica. Deze naam is waarschijnlijk ontleend aan de kleur en tekening van de bloem. Verspreiding Het verspreidingsgebied is de groep zuidelijke eilanden in de Sulu-archipel (Filippijnen), waar de planten op bomen groeien die langs riviertjes staan in het laagland op een hoogte van 500 m. Beschrijving De planten groeien in een horizontale, lichtelijk omhoog gerichte stand tegen de bomen, of in humusnesten in de vorken van takken in de bomen. Zij hebben geen schijnknollen of bulben; de bladeren ontspruiten uit het hart van de wortelstok dicht opeen, zijn langwerpig, puntig aan het uiteinde, met een nerf in het midden. De kleur is effen grasgroen; bladeren stevig, niet vlezig en dik. De planten vormen niet meer dan 1 nieuw blad per groeiseizoen; het zijn uitgesproken trage groeiers. De wortels zijn zilverachtig en rond, vertakken zich en zijn 5 mm in dwarsdoorsnede. De bloemtakken ontwikkelen zich aan de onderkant van de wortelstok en tussen de onderste, oudste bladeren. Ze worden ongeveer 30 cm lang en jaar na jaar worden op dezelfde bloemtak bloemen geproduceerd. Naarmate de plant ouder wordt, neemt het aantal bloemen toe. Zoals exemplaren van andere ondersoorten van Ph.lueddemanniana wel doen, produceren zij geen jonge planten aan de bloemtakken.
