The problem of protection and conservation of rare and endangered plant species in the wild is currently the topic of discussion and research worldwide. The Orchidaceae plants are of special concern. Orchids are so well adapted to their environments. Moreover, they have special requirements that makes it difficult to transplant them from the wild a...

Cardiocrinum cordatum (Thunb.) Makino var. glehnii (F. Schmidt) Hara (Liliaceae) a rare species is characterized by an underdeveloped embryo during dissemination and by the difficulty of seed germination. The aim of the work was to clarify the type of seed dormancy and optimization of seed reproduction in this species by combining various methods:...

We carried out an allozyme analysis to investigate polymorphism and genetic structure of the populations of D. incarnata and D. ochroleuca in regions of their joint growth in Russia and Belarus. We found that D. ochroleuca individuals in the populations of the Urals and Siberia, which are distant fragments from the main range of the species, do not...

28.03.2016 г. Представлены результаты изучения полиморфизма и генетической структуры популяций Dacty-lorhiza salina и D. incarnata, произрастающих в Забайкальском крае и Бурятии, по данным аллозим-ного анализа восьми генных локусов (PGI, NADHD, SKDH, GDH, PGM, DIA, ADH, IDH). Установле-на специфичность аллельной структуры локусов SKDH, PGM и IDH дл...

A cytoembryological study of the seed formation in Orchis purpurea Huds. ssp. purpurea from two populations of Krasnodar region, which are characterized by low real seed productivity, is carried out. It is established that the seeds become nonviable up to the moment of dissemination because of the lethal anomalies in embryo and suspensor developmen...

The article provides data on the fruit set, heterospermy and quality of seeds in Orchis purpurea subsp. caucasica. The species is rare and listed in the Red Data Book of Russian Federation (2008). It propagates mainly by seed. It is shown that in the studied localities in Novorossiysk and Abinsk districts of Krasnodar Territory in 2009 – 2014 the a...

The present work gives a detailed study of in vitro shoot organogenesis of the ornamental onion A. altissimum Regel from the buds of the middle layer of the inflorescences. The course of morphogenesis was examined by light and scanning electron microscopy. Histological observation revealed that during 3 - 5 days of culture on the BDS medium supplem...

Ten gene loci of nine enzyme systems (PGI, 6-PGD, NADHD, SKDH, GDH, PGM, DIA, ADH, GOT-1, and GOT-2) were analyzed in Cypripedium calceolus, C. macranthon, C. shanxiense, and C. ventricosum plants from the south of the Russian Far East. Alleles of loci 6-PGD, NADHD, GDH, ADH, GOT-1, and PGIproved to be diagnostic for C. calceolus and C. macranthon....

The study is carried out of seeds at different stages of their development in an individual of Dactylorhiza fuchsii (Druce) Soó, characterized by a high share of nonviable seeds by the moment of dissemination. It is shown that the embryo is present in the majority of the seeds at the early stage of their development. In most cases, however, structu...
