在UV-B辐射增强条件下稀土镧对大豆品质的影响
Effect of La on the Soybean Quality under Elevated Ultraviolet-B Radiaion
摘要
Abstract
Enhanced ultraviolet-B (UV-B)radiation may have side effects on plant quality and,lanthanum(La) is reported to have protective potential on plants under adverse environment.In this study,soybean cv.Dongnong 47 was planted in greenhouse,24 h after sprayed with LaCl3 solutions (0,20,30,40,50,60 rmg· L-1) at seedling,flowering and both stage,soybean plants were exposed to supplementary UV-B radiation.Seed protein content (PC),fat content (FC) and their total content (PFC) were determined after harvest.All LaCl3 sprayed at seedling decreased PC and PFC,while increased FC and,30 mg·L-1 LaCl3 significantly increased FC by 3.78％.LaCl3 applied at flowering promoted PC,FC and PFC,except that of FC under 40 mg· L-1 LaCl3,highest increment of PC (4.46％),FC (1.50％) and PFC (2.24％) were obtained at 40,60 and 40 mg· L-1 LaCl3,respectively.At both seedling and flowering,spraying 60 mg· L-1 LaCl3 increased PC by 0.64％,and 20 mg· L-1 LaCl3 increased FC by 0.46％.Results suggest under elevated UV-B irradiation,applying 40 mg· L-1 LaCl3 at flowering will contribute to the improvement of total content of protein and fat in soybean.关键词
