Abstract
The paper presents the results of different ways of overcoming dormancy of seeds of Oxytropis chankaensis Jurtz., a rare endemic species of the Far East characterized by small isolated populations. The peculiarities of seed germination under the influence of various abiogenic factors were studied: concentrated sulfuric acid, stratification, seed hilum puncture and abrupt temperature difference. A protocol for introducing the species studied to culture in vitro in order to preserve this endemic has been developed. The assessment of seedling viability after exposure to each of the factors was carried out. It was shown that the most effective and fastest way of scarification is the use of concentrated sulfuric acid. Stimulation of seed germination by this factor leads to 100 % seed germination and obtaining more than 90 % of viable plants capable of microclonal multiplication.
期刊介绍：
Botanica Pacifica (BP) publishes peer-reviewed, significant research of interest to a wide audience of plant scientists in all areas of plant biology (structure, function, development, diversity, genetics, evolution, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, fungi, and lichens). BP requires authors to frame their research questions and discuss their results in terms of contemporary problems of plant biology. While the geographic focus of the journal is the Pacific region, research submissions that demonstrate clear linkages with other regions are welcome. BP aims to foster the exchange of research ideas between countries with diverse cultures and languages.
