Four varieties of winter wheat with different return green rates were used to analyze the plasma membrane stability and the factors that affect winter wheat in the frigid region during winter. The removal of reactive oxygen species, the degree of plasma membrane impairment, water composition and content, and the changes in cell viability in the crowns, which contain the growing point, were studied...
Two new oleanane-type triterpenoid saponins, bodiniosides C (1) and D (2), were isolated from the aerial parts of Elsholtzia bodinieri. Their structures were determined by one- and two-dimensional NMR techniques, including HMQC, HMBC and HMQC-TOCSY experiments, as well as acid hydrolysis and GC analysis.
The overwintering survival ratio of the cultivar Dongnongdongmai 1 with strong cold-resistance in paramos of Heilongjiang Province in China are over 85%. The tillering nodes are the most important organs for overwintering survival of winter wheat, because there are more substances associated with cold resistance in tillering nodes than those in leaves and roots. Proteins in the tillering nodes of...
