Plants to adapt to the major discoveries of saline-alkaline mechanisms

Researcher Song Fengbin from Northeast Institute of Geography and Agricultural Ecology, Chinese Academy of Sciences and his enlightened Ph.D. student Wang Bo and others, after intensive research in the past two years, discovered that salt is an important mechanism for oats to adapt to salinity. In this study, scanning electron microscopy (SEM) was used to observe that oats excreted a large amount of salt crystals through the stomata on the surface of the leaves. This is a major discovery in the field of plant salinity-adaptive mechanisms, providing screening for salt-tolerant plants and plant salt-tolerant breeding in the future. Reference and reference basis. At the same time, through the germination test, pot experiment and field test, the research group identified the mechanism of salt-alkali stress on oats and the adaptation of oats to saline-alkali stress from the aspects of external morphology, physiological and biochemical indicators, ultrastructural changes, and yield formation. The sexual response systematically revealed the physiological mechanism of oats adapting to saline-alkaline stress, and based on the mechanism study, a preliminary model for the high-efficiency regulation of oat alkali resistance was established.
