The country has come a long way from an era of exploration phase, identification and preparation of inventories of orchids, yet it appears to be an unfinished endeavour. Besides documenting the ethnobotanical knowledge of various orchid species, in vitro tissue regeneration, micropropagation, and cell culture protocols have also been standardised for many orchid species. However, in contrast to the available diversity, ecological and molecular studies of orchids have not been conducted extensively in the country. Although above (pollinators) and below ground (fungal endophytes) mutualists have been recorded for few orchid taxa, the underlying functional mechanisms, which facilitate the processes, are unexplored. The present review offers insights into the major works that have been carried out on orchids in India, and also highlights several areas of potential research that are neglected or understudied. Most importantly, there is a need to broaden the objectives while training orchidologists. It appears that unification of subdisciplines is a priority in orchid biology in general, and conservation in particular.","PeriodicalId":39825,"journal":{"name":"Rheedea","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43967744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epiphytism has evolved only within certain subgroups of the Orchidaceae, and it is unclear what seed adaptations favour epiphytism, as compared to the terrestrial lifeform. Seed attachment to bark has attracted very little attention in orchid biology. So far, Chiloschista lunifera (Rchb.f.) J.J.Sm. is the only species reported to have an actual attachment mechanism. In this study, we attempt to confirm old records of seed coat mucilage production in 15 test species, and provide data on seed weights and lengths to test differences according to life form. Uptake of water and seed attachment are likewise compared. Seeds of epiphytic species tended to be shorter than those of terrestrials. In epiphytic species we found cases of very fast germination, within 20 h of exposure to water. Mucilage production could not be demonstrated microscopically. Attachment of dry seeds to a vertical smooth surface was generally high, in both epiphytic and terrestrial species, but in many species attachment was increased by previous water exposure.","PeriodicalId":39825,"journal":{"name":"Rheedea","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46638419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
