MARSUSI,CAHYANTO MUKTI,YUDI SETIAWAN,SITI KHOLIDAH
Biodiversitas , 2001,
Abstract: The objective of the research was to know the species of epiphytic orchids in Jobolarangan forest. The orchid samples were taken from all stand-plants. The plants were chosen randomly by considering the diversity and richness of orchids that attach on it. Each plant was sampled in three repetitions. Sampling of orchids existence in the plant’s stand were done using transect method through a zonation system. In this research 11 epiphytic-orchids such as Bulbophyllum bakhuizenii Stenn, Coelogyne miniata Lindl, Coelogyne rochussenii de Vr., Dendrobium bigibbum Lindl., Dendrobchilum longifolium, Eria bogoriensis, J.J.S. Liparis caespitosa (Thou.) Lindl., Liparis pallida (Bl.). Pholidota globosa (Bl.) Lindl., Polystachya flavescens (Bl.) J.J.S., and Trichoglottis sp. were found. The host plant stand that was attached with most orchids was Schefflera fastigiata and Saurauia bracteosa, generally in zone three.

Abstract: considering the performance of cam epiphytes under high levels of radiation or in shaded environments, with growth rate proportional to light intensity, the objective of this work was to evaluate the effects of long-term light stress on the growth of a brazilian epiphytic orchid, cattleya forbesii lindl. x laelia tenebrosa rolfe. two groups of plants were used in the first experiment, one under 90% (@ 1,650 μmol.m-2.s-1) of photosynthetically active radiation (par) and the other maintained under 22.5% (@ 400 μmol.m-2.s-1). in the second experiment the diffusive resistance, transpiration rate and fluorescence levels were monitored for plants that were under 22.5% of par, under 90% and plants transferred from 22.5 to 90%. our results show that light intensity interfered with growth and development of this orchid. data on the changes in pseudobulb volume throughout the time course of growth suggest that water and reserves stored in the back shoots are translocated to the current shoot. regarding stomatal resistance, plants under 22.5% of par reached a largest stomatal aperture during the night, whereas those under 90% only after dawn. after transfer from 22.5% par to 90% par the ratio of fv/fm decreased from approximately 0.8 to 0.7. this suggests the limitation of photoprotection mechanisms in the leaf and the results observed after the transfer of plants from 22.5% to 90% reinforce the possibility that a photoinhibition is reflected in a decrease in growth rate.

Abstract: Considering the performance of CAM epiphytes under high levels of radiation or in shaded environments, with growth rate proportional to light intensity, the objective of this work was to evaluate the effects of long-term light stress on the growth of a Brazilian epiphytic orchid, Cattleya forbesii Lindl. X Laelia tenebrosa Rolfe. Two groups of plants were used in the first experiment, one under 90% (@ 1,650 μmol.m-2.s-1) of Photosynthetically Active Radiation (PAR) and the other maintained under 22.5% (@ 400 μmol.m-2.s-1). In the second experiment the diffusive resistance, transpiration rate and fluorescence levels were monitored for plants that were under 22.5% of PAR, under 90% and plants transferred from 22.5 to 90%. Our results show that light intensity interfered with growth and development of this orchid. Data on the changes in pseudobulb volume throughout the time course of growth suggest that water and reserves stored in the back shoots are translocated to the current shoot. Regarding stomatal resistance, plants under 22.5% of PAR reached a largest stomatal aperture during the night, whereas those under 90% only after dawn. After transfer from 22.5% PAR to 90% PAR the ratio of Fv/Fm decreased from approximately 0.8 to 0.7. This suggests the limitation of photoprotection mechanisms in the leaf and the results observed after the transfer of plants from 22.5% to 90% reinforce the possibility that a photoinhibition is reflected in a decrease in growth rate.

The effect of some organic compounds and NAA application on the in vitro growth of the black orchid (Coelogyne pandurata Lindl.)  [PDF]

Biodiversitas , 2006,
Abstract: Coelogyne pandurata Lindl. is a lowland epiphytic orchid that has pale green flowers with typically black markings on the lips. This species conventionally propagated asexually by rhizome. This orchid is now facing a great conservation problem and threatened to extinction due to human exploitation. That is why conservation activities such as developing proper cultivation, are urgently required. An in vitro experiment was conducted at the Laboratory of Tissue Culture at Bogor Botanic Garden. The experiment was carried out using a completely randomized design with two factors and ten replications. The treatments were the supplementation of the basal media i.e. Vacin and Went added with sugar, activated charcoal and agar, with 30 different combinations of organic compounds i.e., coconut water 250 mL/L, banana 150 g/L, potato 200 g/L, sweet potato 150 g/L, soybean 150 g/L and no organic compound as a control, and application of NAA (0, 5, 10, 15, and 20 ppm). The result showed that there was a significant effect of the organic compounds and NAA application on the length and the number of roots, height, number of leaves and number of shoots produced by the explants. The combination of sweet potato 150 g/L without NAA application showed the best result.

Bioscience Discovery , 2012,
Abstract: The present paper deals botanical description with four Agrostophyllum epiphytic Orchid species viz., Agrostophyllum brevipes, A. callosum, A. myrianthum and A. planicaule diversity resources and distribution in Darjeeling Himalaya of India. This attempt is the first step to correct taxonomic identification to workout currently accepted botanical names with ecological status, voucher specimen numbers, habitat, altitudinal ranges, phenology and local and general distribution of Agrostophyllum species in the regions. For the assessment of present ecological status, plot of 10mx10m quadrates was laid down diagonally in the field for epiphytic Orchid species.

Abstract: Yulia ND, Budiharta S, Yulistyarini T (2011) Analysis of epiphytic orchid diversity and its host tree at three gradient of altitudes in Mount Lawu, Java. Biodiversitas 12: 225-228. The aim of this study was to observe epiphytic orchid diversity and their host trees at three different altitudes (1796, 1922 and 2041 m asl) at southern part of Mount Lawu, District of Magetan, East Java. Line transect of 10 x 100 m was set up and then divided into ten plots (as replicates) of 10 x 10 m. At each plot, species name and number of individual of epiphytic orchids, and species name, number of individual and diameter at breast height (dbh) of host trees were recorded. The result showed that there were 19 species of epiphytic orchid recorded at the study sites. There were significantly different among gradient altitude in number of epiphytic orchid species (F = 3.7; df = (2, 27); P < 0.05). The highest number of species of epiphytic orchid was recorded at the altitude of 1922 m asl (6.6 species/100 m2) while the highest number of individual was recorded at the altitude of 1796 m asl (1337.7 individuals/100 m2). The study site at altitude of 1922 m asl was recognized as the denser and richer in species of host trees (2.3 species/100 m2 and 3.5 individuals/100 m2 respectively). However, the highest basal area of host tree was recorded at the altitude of 2041 m asl (4558 cm2/100 m2).

Abstract: Yulia ND, Budiharta S (2011) Epiphytic orchids and host trees diversity at Gunung Manyutan Forest Reserve, Wilis Mountain, Ponorogo, East Java. Biodiversitas 12: 22-27. Natural forests in Wilis Mountain have been destroyed by forest fires, landslides and illegal logging. As a consequence, biological diversity in this area is threatened by local extinctions, particularly of orchid species. This study was aimed to explore, document and analyze the diversity of epiphytic orchids at Gunung Manyutan Forest Reserve, a natural forest area in Wilis Mountain. Purposive sampling on 1 hectare (50 x 200 m2) contiguous plot was used. This plot was divided into eight subplots (25 x 50 m2). All data on orchid species were recorded including its number, host trees and zone of the host tree where the orchid attached. The results showed that there were 29 epiphytic orchid species recorded. Flickingeria angulata was the most abundant species (Relative Abundance of orchids/ %Fo = 38.74), continued by Appendicula sp. (%Fo = 10.91) and Eria hyacinthoides (%Fo = 6.57). The three most important host trees were Pinus merkusii, Schima wallichii and Engelhardia spicata. Zone 3 (bottom part of the branches) was revealed as the most favorable part at the host tree (281 individuals), while Zone 1 (bottom part of the main stem) was the least preferable one.
