Molecular and morphological phylogenetics of the digitate-tubered clade within subtribe Orchidinae s.s. (Orchidaceae: Orchideae) [PDF]

open access: yes, 2018
The digitate-tubered clade (Dactylorhiza s.l. plus Gymnadenia s.l.) within subtribe Orchidinae is an important element of the North-temperate orchid flora and has become a model system for studying the genetic and epigenetic consequences of organism-wide

Nectar and oleiferous trichomes as floral attractants in Bulbophyllum saltatorium Lindl. (Orchidaceae) [PDF]

open access: yes, 2017
Although many Orchidaceae have deceit flowers that produce no reward, the most common reward, when present, is nectar. Bulbophyllum, however, is unusual in that the labellar secretions of most species investigated to date lack sugars, and, therefore ...

Less is more: low-cost in vitro propagation of an Endangered Italian orchid

open access: yesNature Conservation Research: Заповедная наука, 2020
Orchids are among the most widely distributed plants but also the most threatened by biotic and abiotic factors. Their interactions with specific symbiotic fungi during germination in natural environments make their propagation challenging for ...

Further advances in orchid mycorrhizal research [PDF]

open access: yes, 2007
Orchid mycorrhizas are mutualistic interactions between fungi and members of the Orchidaceae, the world’s largest plant family. The majority of the world’s orchids are photosynthetic, a small number of species are myco-heterotrophic throughout their ...

Gibberellic acid and 6-benzyladenine reduce time to flowering and improve flower quality of Laelia anceps

open access: yesFolia Horticulturae, 2021
The efficacy of plant growth regulators (PGRs) has been demonstrated in the flowering of economically significant orchid hybrids, but studies of their effects in wild species with commercial potential are scarce.

The use of chloroplast genome sequences to solve phylogenetic incongruences in Polystachya Hook (Orchidaceae Juss) [PDF]

open access: yes, 2018
Background: Current evidence suggests that for more robust estimates of species tree and divergence times, several unlinked genes are required. However, most phylogenetic trees for non-model organisms are based on single sequences or just a few regions ...

The formation of integuments, megasporogenesis and megagametogenesis in Dendrobium catenatum, with special discussions on embryo sac types and section techniques [PDF]

open access: yesBotanica Serbica, 2021
The formation of integuments, megasporogenesis and megagametogenesis in Dendrobium catenatum, an economically important orchid, are observed. After pollination, mitotic cell divisions of the placental epidermis result in the formation of a branching ...
