Although embryo mortality only weakly reduces gene flow between the two species, hybrid sterility appears to be stronger, which is consistent with the observed pattern of an earlier insurgence of hybrid sterility between related species (Scopece et al. Transitions between self-compatibility and self-incompatibility and the evolution of reproductive isolation in the large and diverse tropical genus For induction of PLBs, ZR at 14.0 μM was most effective for C. aloifolium while BA at 11.0 μM was optimum for D. nobile. (A) seedsThe continuous loss of habitats has increased the importance of orchid conservation efforts involving ex situ propagation. For each species, the fruit production component was defined as: Niche differentiation between parentals and their hybrid is an important isolating mechanism. Orchis purpurea Hudson. A cytokinin was required by Cypripedium calceolus and Epipactis hellborine but was not necessary for Lisiera ovata and Dactylorhiza maculata.

Eventually almost all of the transferred protocorms developed to plantlets, which later formed minitubers. morio) and further aims to obtain a mature orchid plant by following the
It is hardy to zone (UK) 5 and is not frost tender.
(In plants it has often been reported that gene flow between closely related species may be impeded by the breakdown of phenotypic floral traits involved in attraction of pollinators (Schluter To compare the contribution of prepollination versus postpollination and of prezygotic versus postzygotic mechanisms, following Lowry et al. Average number of PLBs per TCS explant was high in both the cases (28.2 in C. aloifolium, and 34.0 in D. nobile) though inhibitory effect was noticed with cytokinins above the optimal level.

In southern Europe they are collected and dried to produce a flour that is mixed with sugar, flavourings, and liquid (such as water or milk) to produce a drink called salep. It also showcases the development of botanical illustration using orchids as examples.In this study, the goal was the germination and propagation of Orchis sancta L. which is endangered due to uncontrolled collection and used in obtaining salep, in vitro conditions.
The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. increased by using SV growth medium, following their natural hardening off
