Dendrobium officinale Kimura et Migo is an orchid with both medicinal and edible values and a high economic value. The wild resources of D. officinale are in an endangered state. Compared with the wild D. officinale, cultivated D. officinale exhibits inferior quality and a low content of medicinal...

This study reports on extensive and in-depth investigations into the morphological, photosynthetic, and physiological indices of 10 different types of Cypripedium plant introduced from Changbai Mountain. It is an important prerequisite for the ex situ conservation of Cypripedium plants to provide...

The vanilla fruit (Vanilla planifolia Andrews) generates an important economic income; however, the best paid fruits are those of greater length (gourmet type), so strategies are needed to obtain fruits of that type. Given this, one option is the induction of metaxenia, understood as the increase...

Understanding the critical stages in ovule development is essential for optimizing in vitro seed propagation, cryopreservation, and indirect somatic plant embryogenesis. We studied the main stages of the megasporogenesis and megagametogenesis of Coelogyne speciosa subsp. fimbriata (J.J.Sm.)...

The morphostructure of inflorescences in the genus Coelogyne Lindl. was studied for the first time using a structural-rhythmological approach. Three species of Coelogyne were used to describe one-season, intercalary, and all-season inflorescences. In C. monilirachis, a new type of all-season...

Grammatophyllum speciosum is a traditional plant with beneficial functionalities for health. G. speciosum extracts can inhibit collagenase and nitric oxide without cellular toxicity in keratinocytes. The extracts have shown potential for use and formulation as cosmeceutical ingredients. However,...

A phytochemical investigation of Dendrobium gratiosissimum Rchb. f. (Orchidaceae) led to the isolation of four new flavone C-glycosides (1-4) together with four known ones (5-8). The chemical structures of the new flavone C-glycosides (1-4) were elucidated by extensive spectroscopic data analysis...

11 phenolic compounds, including two new bibenzyl-phenylpropane hybrids, dendrophenenes A-B (1-2), were isolated from the cultivated Dendrobium devonianum Paxt. Compound 1 is a rare bibenzyl-phenylpropane hybrid with a coumarin core. All structures were elucidated by extensive spectroscopic...

A new study shows that Vanilla species are unique among orchids for having evolved a multimodal mechanism of seed and fruit dispersal. Bees inadvertently transport seeds externally while collecting fragrance or nest material from dehiscent fruits. Rodents and marsupials consume and disperse...

Background: Limited number of studies have been conducted to determine the ethnobotanical uses of geophytes and to scientifically document traditional knowledge associated with them. Questions: What is the ethnobotanical usage culture of geophytes in Sakarya province? Studied species: Geophytes....
