Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Засоление почв является серьезной проблемой Республики Казахстан. Один из путей повышения толерантности сельскохозяйственных культур к солевому стрессу – использование сообществ эндофитных микроорганизмов, повышающих устойчивость растений к различным повреждающим воздействиям. В данной работе показано влияние эндофитов растений, произрастающих в засушливых условиях, на способность проростков пшеницы противостоять солевому стрессу. Наилучшие результаты на синтетической среде показала ассоциация из растения Erigeron canadensis в сочетании с эндофитным актиномицетом пшеницы, отнесенным к виду Streptomyces curacoi. Влияние предварительной адаптации эндофитных микроорганизмов к хлориду натрия на устойчивость растения-хозяина к засолению было показано нами впервые. Soil salinization is a serious problem in the Republic of Kazakhstan. One of the ways to increase the tolerance of agricultural crops to salt stress is the use of communities of endophytic microorganisms, which increase the resistance of plants to various damaging effects. This work shows the influence of endophytes of plants growing in arid conditions on the ability of wheat seedlings to withstand salt stress. The best results on a synthetic medium were shown by an association from the plant Erigeron canadensis in combination with an endophytic wheat actinomycete assigned to the species Streptomyces curacoi. The influence of the preliminary adaptation of endophytic microorganisms to sodium chloride on the resistance of the host plant to salinity was shown by us for the first time.
