Seed Germination of the Corpse Giant Flower Amorphophallus Titanum
Latifah and Purwantoro - Seed Germination of The Corpse Giant Flower Amorphophallus titanum SEED GERMINATION OF THE CORPSE GIANT FLOWER Amorphophallus titanum (Becc.) Becc. Ex Arcang: THE INFLUENCE OF TESTA [Perkecambahan Biji Bunga Bangkai Raksasa Amorphophallus titanum (Becc.) Becc. ex Arcang: Pengaruh Testa] Dian Latifah and RS Purwantoro 1Center for Plant Conservation-Bogor Botanic Garden, Indonesian Institute of Sciences (LIPI) Jl. Ir. H. Juanda no.13, Bogor, Indonesia 16122 e-mail: [email protected] ABSTRACT Amorphophallus titanum is famous as the gigantic inflorescense and economically prospective due to its 20% glucomannan contents. Various cultivation techniques including germination have been conducted due to the delay in the seed germination of Amorphophallus titanum. Previous studies revealed that A. titanum seeds has not produced faster and better germination rate. Therefore this research was aimed to test the following hypotheses: (1) Fruit pericarp and the pericarp inhibited the germination, (2) testa/seed coat inhibited germination, (3) GA3hormone promoted the germination rate. The germination pattern was also monitored. The experiments consisted of: Experiment 1: sowing the fruit with the seeds inside and Experiment 2 with two treatments: testa peeling and GA3 hormone treatments. The results of Experiment 1 showed that the fruit pericarp and the pericarp inhibited the germination for 124 days. Experiment 2 resulted in: (1) the delay of the germination for 7-35 days caused by the testa/seed coat, (2) GA3 hormone promoted the germination rate 2.19 coefficient of germination rate; and higher GA3 (1000 ppm) may enhance the seedling growth (reached the highest 23.6 ± 1.3).We also recorded developmental stages from the seed germination, first-leaf emergence and tuber development in series of photographs overtime during the experimental period. -

Biodiversitas 19: 140-152. Bogor Botanic Gardens is an ex-situ conservation centre, covering an area of 87 ha, with 12,376 plant specimens, collected from Indonesia and other tropical countries throughout the world. One of the richest collections in the Gardens comprises members of the aroid family (Araceae). The aroids are planted in several garden beds as well as in the nursery. They have been collected from the time of the Dutch era until now. These collections were obtained from botanical explorations throughout the forests of Indonesia and through seed exchange with botanic gardens around the world. Several of the Bogor aroid collections represent ‘living types’, such as Scindapsus splendidus Alderw., Scindapsus mamilliferus Alderw. and Epipremnum falcifolium Engl. These have survived in the garden from the time of their collection up until the present day. There are many aroid collections in the Gardens that have potentialities not widely recognised. The aim of this study is to reveal the diversity of aroids species in the Bogor Botanic Gardens, their scientific value, their conservation status, and their potential as ornamental plants, medicinal plants and food. -

Anthurium Andraeanum) As a Cut Flower in Bangladesh
Journal of Bangladesh Academy of Sciences, Vol. 37, No. 1, 103-107, 2013 VARIETAL STUDY OF ANTHURIUM (ANTHURIUM ANDRAEANUM) AS A CUT FLOWER IN BANGLADESH M.S. ISLAM, H. MEHRAJ, M.Z.K. RONI, S. SHAHRIN AND A.F.M. JAMAL UDDIN* Department of Horticulture, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh ABSTRACT Five varieties viz., Caesar, Aymara, Ivory, Jewel, and Triticaca were in use for the study in Randomized Complete Block Design with five replications. Significant differences among cultivars were noted for all attributes evaluated. Variety ‘Triticaca’ had maximum stalk length and diameter, spathe length and breadth, spadix length, vase life and flowers per plant. Through present analysis it is noticed that, variety ‘Titicaca’ are exceedingly preferred because of its attractive flowers, excellent flower size, yield potentiality and long shelf life. Key words: Anthurium, Cut flower, Vase life INTRODUCTION Anthurium (Anthurium andraeanum) is a slow-growing perennial flowering plant that requires shady, humid conditions as found in tropical forests. The genus anthurium is evergreen and belongs to the family Araceae as the plant possesses an underground rhizome with adventitious roots, characteristic of the family. Anthurium characteristically produces numerous inflorescences subtended by brightly colored spathes, which are carried on long, slender peduncles. Spathes are characteristically heart-shaped, flat, puckered and shiny and flowers have a wide range of spathe colors viz., white, pink, salmon-pink, red, light-red, dark-red, brown, green, lavender, cream or multi-colored. The colorful spathe is long-lasting. However, the ‘true’ flowers are found on the spadix and have large numbers of pistils, each surrounded by four stamens. -

A taxonomic revision of Araceae tribe Potheae (Pothos, Pothoidium and Pedicellarum) for Malesia, Australia and the tropical Western Pacific. Telopea 9(3): 449–571. A regional revision of the three genera comprising tribe Potheae (Araceae: Pothoideae) is presented, largely as a precursor to the account for Flora Malesiana; 46 species are recognized (Pothos 44, Pothoidium 1, Pedicellarum 1) of which three Pothos (P. laurifolius, P. oliganthus and P. volans) are newly described, one (P. longus) is treated as insufficiently known and two (P. sanderianus, P. nitens) are treated as doubtful. Pothos latifolius L. is excluded from Araceae [= Piper sp.]. The following new synonymies are proposed: Pothos longipedunculatus Ridl. non Engl. = P. brevivaginatus; P. acuminatissimus = P. dolichophyllus; P. borneensis = P. insignis; P. scandens var. javanicus, P. macrophyllus and P. vrieseanus = P. junghuhnii; P. rumphii = P. tener; P. lorispathus = P. leptostachyus; P. kinabaluensis = P. longivaginatus; P. merrillii and P. ovatifolius var. simalurensis = P. ovatifolius; P. sumatranus, P. korthalsianus, P. inaequalis and P. jacobsonii = P. oxyphyllus. Relationships within Pothos and the taxonomic robustness of the satellite genera are discussed. Keys to the genera and species of Potheae and the subgenera and supergroups of Pothos for the region are provided. -
The Evolution of Pollinator–Plant Interaction Types in the Araceae
BRIEF COMMUNICATION doi:10.1111/evo.12318 THE EVOLUTION OF POLLINATOR–PLANT INTERACTION TYPES IN THE ARACEAE Marion Chartier,1,2 Marc Gibernau,3 and Susanne S. Renner4 1Department of Structural and Functional Botany, University of Vienna, 1030 Vienna, Austria 2E-mail: [email protected] 3Centre National de Recherche Scientifique, Ecologie des Foretsˆ de Guyane, 97379 Kourou, France 4Department of Biology, University of Munich, 80638 Munich, Germany Received August 6, 2013 Accepted November 17, 2013 Most plant–pollinator interactions are mutualistic, involving rewards provided by flowers or inflorescences to pollinators. An- tagonistic plant–pollinator interactions, in which flowers offer no rewards, are rare and concentrated in a few families including Araceae. In the latter, they involve trapping of pollinators, which are released loaded with pollen but unrewarded. To understand the evolution of such systems, we compiled data on the pollinators and types of interactions, and coded 21 characters, including interaction type, pollinator order, and 19 floral traits. A phylogenetic framework comes from a matrix of plastid and new nuclear DNA sequences for 135 species from 119 genera (5342 nucleotides). The ancestral pollination interaction in Araceae was recon- structed as probably rewarding albeit with low confidence because information is available for only 56 of the 120–130 genera. Bayesian stochastic trait mapping showed that spadix zonation, presence of an appendix, and flower sexuality were correlated with pollination interaction type. In the Araceae, having unisexual flowers appears to have provided the morphological precon- dition for the evolution of traps. Compared with the frequency of shifts between deceptive and rewarding pollination systems in orchids, our results indicate less lability in the Araceae, probably because of morphologically and sexually more specialized inflorescences. -
Gnaphalieae-Asteraceae) of Mexico
Botanical Sciences 92 (4): 489-491, 2014 TAXONOMY AND FLORISTIC NEW COMBINATIONS IN PSEUDOGNAPHALIUM (GNAPHALIEAE-ASTERACEAE) OF MEXICO OSCAR HINOJOSA-ESPINOSA Y JOSÉ LUIS VILLASEÑOR1 Departamento de Botánica, Instituto de Biología, Universidad Nacional Autónoma de México, México, D.F., México 1Corresponding author: [email protected] Abstract: In a broad sense, Gnaphalium L. is a heterogeneous and polyphyletic genus. Pseudognaphalium Kirp. is one of the many segregated genera from Gnaphalium which have been proposed to obtain subgroups that are better defi ned and presumably monophyletic. Although most Mexican species of Gnaphalium s.l. have been transferred to Pseudognaphalium, the combinations so far proposed do not include a few Mexican taxa that truly belong in Pseudognaphalium. In this paper, the differences between Gnaphalium s.s. and Pseudognaphalium are briefl y addressed, and the transfer of two Mexican species and three varieties from Gnaphalium to Pseudognaphalium are presented. Key Words: generic segregate, Gnaphalium, Mexican composites, taxonomy. Resumen: En sentido amplio, Gnaphalium L. es un género heterogéneo y polifi lético. Pseudognaphalium Kirp. es uno de varios géneros segregados, a partir de Gnaphalium, que se han propuesto para obtener subgrupos mejor defi nidos y presumiblemente monofi léticos. La mayoría de las especies mexicanas de Gnaphalium s.l. han sido transferidas al género Pseudognaphalium; sin embargo, las combinaciones propuestas hasta el momento no cubren algunos taxones mexicanos que pertenecen a Pseudogna- phalium. En este trabajo se explican brevemente las diferencias entre Gnaphalium s.s. y Pseudognaphalium, y se presentan las transferencias de dos especies y tres variedades mexicanas de Gnaphalium a Pseudognaphalium.

Master's in Agricultural Production by the Rural Federal University of Pernambuco, Academic Unit of Garanhuns, Garanhuns, PE, Brazil; 2. Teacher, doctor at the Federal Rural University of Pernambuco, Academic Unit of Garanhuns, Garanhuns, PE, Brazil. ABSTRACT: Licuri ( Syagrus coronata (Mart.) Becc.) is an ornamental palm tree native of Brazil with great economic potential, because it provides raw material for manufacturing a wide range of products. The objective of this study was to assess the morphology of the fruits, diaspores, seeds, seedlings, and saplings of Syagrus coronata . The study was performed at the Laboratory of Seed Analysis (LSA) of the Federal Rural University of Pernambuco/Academic Unit of Garanhuns-PE, by using licuri fruits collected from the rural area of Caetés-PE. It was evaluated fruit morphology, diaspores, seeds, seedlings and saplings. Germination, in the form of cotyledon petiole emergence, began 15 days after sowing, is hypogeal, cryptocotylar, and remote tubular. It is slow and uneven, extending up to 60 days after the first eophyll appears. The saplings have alternate, pinnate, glabrous, entire leaves with parallel venation and sheath invagination. The primary roots persistent, the secondary roots arise from the stem root node in the primary root, and lateral roots only fasciculate was evidenced when the change was 300 days, and must remain in the nursery for at least 360 days after germination before taking it to the field, due to the slow development of this species. -

In this study, we report success in generating transgenic Anthurium andraeanum cv Arizona using Agrobacterium GV3101 strain harboring a binary vector carrying gfp as a reporter gene. The possibility of facilitating the screening process for transgenic plants expressing functional proteins using gfp marker was explored. In order to realize high transformation efficiency, different explant sources including undifferentiated callus pieces and petioles were compared for their regeneration efficiency and susceptibility to Agrobacterium-mediated transformation. We also optimized the concentration of AS added to co-cultivation media. Genomic PCR revealed that 11 of the 22 resistant plantlets regenerated on selective medium were successfully transformed. Green fluorescence was observed using a fluorescence microscope in 7 of the 11 PCR-positive plants, indicating GFP was expressed stably in the transformed Anthurium andraeanum.
