Orchid seeds, which are produced in abundance, are particularly small and light. Some orchid species are anemochorous, i.e., bear seeds that are dispersed by wind. To characterize the seeds of Japanese orchids, we measured the size of seeds and embryos of 68 Japanese orchid species. Most orchid seeds had a length of 0.3 to 2 mm and a width of 0.07 to 0.2 mm. Embryo length and width were 0.1 to ...
Basidiocarps of Trametes versicolor with an epiphytic flora (including Trebouxia sp.) collected from north-central Rhode Island were incubated in an atmosphere of C labeled CO2 for 6 hours. Using autoradiography, the location of the fixed CO2 was determined at 6h, 12h, 24h, 48h, 96h, and 192h. The fixed C was recorded in the epiphytic algae after 6h, and at all subsequent times. After 192h the ...
Question: What are the relative influences of human impact, macroclimate, geographic location and habitat related environmental differences on species composition of boreal epiphytic macrolichen communities? Location: Troms county in northern Norway. Methods: Detrended Correspondence Analysis revealed the main gradient structure in lists of epiphytic macrolichen species from deciduous forests. ...
Without any root contact with the soil, epiphytic bryophytes must experience and explore poor, patchy, and heterogeneous habitats; while, the nitrogen (N) uptake and use strategies of these organisms remain uncharacterized, which obscures their roles in the N cycle. To investigate the N sources, N preferences, and responses to enhanced N deposition in epiphytic bryophytes, we carried out an in ...
Previously we developed genomic resources for orchids, including transcriptomic analyses using next-generation sequencing techniques and construction of a web-based orchid genomic database. Here, we report a modified molecular model of flower development in the Orchidaceae based on functional analysis of gene expression profiles in Phalaenopsis aphrodite (a moth orchid) that revealed novel role...
Abstract Cycnoches haagii Barb. Rodr. is an epiphytic orchid very targeted by collectors, but no reference was found in the literature about its reproductive biology. Thus, purpose of this study to obtain initial information regarding pollination types and influence on seed viability native Brazilian Cerrado, order enable future propagation preservation programs. Pollination among flowers same ...
