В статье рассматриваются вопросы введения в интродукцию редкого, находящегося под угрозой исчезновения, узкоэндемичного растения Rosa iliensis Chrshan. семенным путем в условиях степного пояса Заилийского Алатау. Отмечается что результаты исследований были положительными. Несмотря на то, что из 100 посеянных семян всходы дали всего лишь от 10 до 20%, из появившихся всходов от 90 до 99% благополучно прижились. Это дает возможность в перспективе рассмотреть вопросы интродукции Rosa iliensis Chrshan. семенным путем с большим оптимизмом. Причем введя Rosa iliensis Chrshan. в интродукцию, мы можем одновременно решить несколько важных вопросов. Главные из них: сохраним Rosa iliensis Chrshan. от исчезновения; создавая искусственную плантацию Rosa iliensis Chrshan., обеспечим витаминную промышленности и фармацевтическую отрасли Республики Казахстан натуральным и дешевым сырьем; Rosa iliensis Chrshan. можем рекомендовать для озеленения парков, скверов, аллей городов, районных центров и отдаленных населенных мест; введя в интродукцию Rosa iliensis Chrshan. в ботанических садах Республики Казахстан, можно использовать его в качестве маточника для скрещивания с культурными сортами с целью выведения новых сортов Казахстанских садовых роз.

The article gives a geobotanical characterization of plant communities of the population of the rare, endemic plant Rosa iliensis in the floodplain of the river Ili. The assocations of three cenopopulations and the percentages of vegetation cover in this population, the vegetation cover of tiers, are also described. Within each cenopopulation, a 10×10 transect was constructed and the age structure of the vegetation cover in it was determined. In the upper reaches of the river or the state of life of Rosa iliensis can be called satisfactory. Because here Rosa iliensis blooms and bears fruit every year. However, not a single seedling of this plant was found within the populations. This indicates that Rosa iliensis in natural conditions propagates by seeds extremely rarely and its renewal is mainly vegetative, root offspring. Taking this into account, we suggest that the floodplain of the upper Ili river, where the population of Rosa iliensis is found, conduct constant monitoring work and thereby keep the state of its population under control. In addition, we offer Rosa iliensis Chrshan. to be introduced in the main botanical garden of Almaty and the Ili Experimental Botanical Garden of the Balkhash district of Almaty region.

The article provides brief geobotanical characteristics of plant communities of three populations of R. iliensis Chrshan. found in the floodplains of the Ili and Sharyn rivers, as well as presents the morpho-anatomical structure of vegetative organs (stem and leaf) of the species under study. R. iliensis Chrshan. is undoubtedly a rare, endangered species of the flora of Kazakhstan. Its distribution area is shrinking from year to year as a result of the anthropogenic pressure on the environment. The biometric indicators of vegetative organs in the samples collected from populations 1 and 2 were approximately the same. The indicators of the samples collected from population 3 differed substantially. This is a completely natural process, since there are substantial differences in the climatic conditions of the upper and lower parts of the basin where the Ili River flows: a sharp increase in temperature and a decrease in precipitation from high to low hypsometric levels of the basin. Moreover, there is a gradual aridization of the territory from east to west. Naturally, this entails a change in both soil and vegetation cover as well as leaves its mark on the morpho-anatomical structure of vegetative organs. With this in mind, the authors recommend continuous monitoring of the state of the populations at the three sites where R. iliensis Chrshan. was found.
