Effect of Cryoconservation on Seed Germination of Rare Tropical Orchids
TLDR
The feasibility of the conservation of mature seeds of some tropical orchids by freezing in liquid nitrogen was demonstrated, which offers opportunities for creating a cryobank ofOrchids.
Cryopreservation of seeds and protocorms of rare temperate orchids
TLDR
Germination rates of seeds after their exposure to liquid nitrogen were species-depended and could be either higher or lower than in the unfrozen control, while growth rates of protocorms of the same species obtained from seeds collected in various Russia regions and cultured for 5 months were no significant difference.
The Effect of Seed Cryopreservation on the Development of Protocorms by the Hybrid Orchid Bratonia
TLDR
Study of the influence of storage in liquid nitrogen on the viability of seeds of the hybrid orchid Bratonia and further development of its protocorms in vitro found that cryopreservation had little effect on the subsequent growth of protOCorms on the agarized MS and in liquid Morel media.
Cryopreservation of Seeds of Some Tropical Orchids
TLDR
It is shown that cryopreservation (storage in liquid nitrogen at –196 ° C) of seeds, shoot meristems, and cells in vitro could be used in addition to conventional methods of conservation of endangered species of plants.
Colonization strategy of the endophytic plant growth‐promoting strains of Pseudomonas fluorescens and Klebsiella oxytoca on the seeds, seedlings and roots of the epiphytic orchid, Dendrobium nobile
TLDR
This work aimed to investigate the distribution of plant growth promoting rhizobacteria (PGPR) at different stages of orchid development and to study if there is any selective specificity in choosing PGPR partners.
Localization of Associative Cyanobacteria on the Roots of Epiphytic Orchids
This work is the first study of the localization of phototrophic microorganisms in the rhizoplane and velamen of epiphytic orchids, namely, on the aerial and substrate roots of Acampe papillosa and
Microbiota of the Orchid Rhizoplane
TLDR
In orchids occupying different econiches, the spectra of the bacterial genera revealed differed, and the microbial complex of the terrestrial orchid rhizoplane differed from that of the surrounding soil.
Dependence of epiphytic community on autochthonous and allochthonous sources of nitrogen in three forest habitats of southern Vietnam
TLDR
It is hypothesized that, in the case of preferential usage of autochthonous sources, a correlation between isotopic composition of epiphytes and phorophytes would be observed, whereas no such correlation suggests mainly external (atmospheric) N sources.
Dendrobium nobile Lindl. seed germination in co-cultures with diverse associated bacteria
TLDR
Data shows that selection provides a good strategy for choosing the active strains for orchid Seeds’ bacterization, since not all known PGPR are useful and successful in building associative frameworks with orchid seeds.
Associative Cyanobacteria Isolated from the Roots of Epiphytic Orchids
TLDR
In the parenchyma of the aerial roots of P. amabilis, fungal hyphae and/or their half-degraded remains were detected, which testifies to the presence of mycorrhizal fungi in this plant.
