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 ...

Two prevalent issues with Gastrodia elata growing in a natural wild environment are the necessary symbiotic seed germination Mycena spp. and long cycle of protocorms into mature rhizomes Armillaria mellea. This study explored most suitable nutrients to germinate seeds developmental stages propagated protocorm/juvenile (jrhs) through tissue culture approach. Adding humic acid, mashed potato, pep...

The characteristics of plant-mycorrhizae associations are known to vary in both time and space, but the ecological consequences of variation in the dynamics of plant-fungus interactions are poorly understood. For example, do plants associate with single fungi or multiple fungi simultaneously, and do the associations persist through a plant's lifetime or do plants support a succession of differe...

The endangered epiphytic orchid, Dendrobium chrysotoxum, is known for its ornamental and medicinal uses. However, knowledge of this orchid’s symbiotic seed germination, protocorm anatomy, developmental morphology completely unknown. In study, we investigated the process development D. chrysotoxum during germination using anatomical technologies scanning electron microscopy. There are six stages...

Symbiotic seed germination for conservation and cultivation of orchids holds colossal merit asmycorrhizal fungus in its system improves their growth adaptability. activity ishighly specific some species, but other cases the same from one species is effective aseries related species. The present work describes inter-specific three fungal isolatesfrom seedling root Vanda thwaitesii to support V.w...

A greater understanding of the relationship between native orchids and their mycorrhizal symbionts is needed to ensure more effective orchid conservation strategies. protocol for symbiotic seed germination seedling development was developed E. geminiflorum. Mature seeds were collected from a naturally occurring population in Ecuador. Putative fungi isolated other species used screen ability fac...
