The significant correlations detected among nodule (N) and trapped (T) isolates related to the similar or distinct populations. more than 60 % N- and 77 % T-isolates tolerant to 3,5 % NaCl; salt tolerant N-isolates formed effective symbiosis with Medicago sativa and M. truncatula significantly more often. Isolates native to the GC area next to aral Sea had possessed the reduced level of salt tolerance in comparison with the isolates originated from Central asian, North-Caucasian and Europe-Siberian GC; that, has related to adaptation processes, which have ensured their viability in extremely salted soils.&lt;img src="http://elibrary.ru/pic/1pix.gif" /&gt;</p></abstract><trans-abstract xml:lang="ru"><p>Анализ солеустойчивости, составов плазмид и симбиотических свойств у изолятов Sinorhizoboium meliloti, выделенных в 4-х генцентрах (Гц) люцерны, выявил достоверные различия между клубеньковыми (к) и почвенными (П) субпопуляциями. более 60 % к- и 77 % П-изолятов устойчивы к 3,5 % NaCl; солеустойчивые к-изоляты достоверно чаще формировали эффективный симбиоз с Medicago sativa и M. truncatula. Изоляты S. meliloti из Приаральского Гц имели сниженный уровень солеустойчивости в сравнении с изолятами из Среднеазиатского, Северо-кавказского и Европейско-Сибирского Гц, что связано с адаптационными процессами, обусловившими их жизнеспособность в экстремально засоленных почвах.&lt;img src="http://elibrary.ru/pic/1pix.gif" /&gt;</p></trans-abstract><kwd-group xml:lang="en"><kwd>MEDICAGO SATIVA</kwd><kwd>M.
