摘要:
在紫外辐射（UV-B）增强条件下，采用盆栽的方式，研究了苗期和开花期喷施不同浓度LaCl3溶液对大豆东农47蛋白质含量、脂肪含量和蛋脂总量的影响，并筛选出LaCl3溶液的最佳喷施浓度和喷施时期。结果表明：在UV-B辐射增强条件下，苗期所有浓度镧处理的蛋白质含量和蛋脂总量都减少，脂肪含量增加；其中30 mg·L-1 LaCl3处理脂肪含量（22.80%）最高，较对照显著增加3.78%。开花期所有浓度镧处理的蛋白质含量和蛋脂总量都增加，除40 mg·L-1 LaCl3处理外脂肪含量也都增加；其中40 mg·L-1 LaCl3处理，大豆蛋白质含量（42.13%）和蛋脂总量（63.80%）最高，分别较对照增加4.46%和2.24%；60 mg·L-1 LaCl3处理的脂肪含量（22.40%）最高，较对照增加1.50%。苗期和开花期各喷施60 mg·L-1? LaCl3的大豆籽粒蛋白质含量（42.57%）最高，较对照增加0.64%；20 mg·L-1LaCl3处理脂肪含量（22.03%）最高，较对照增加0.46%。综合考虑，在UV-B辐射增强条件下，开花期喷施 40 mg·L-1 LaCl3溶液有利于提高大豆的品质。
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 mg·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〖DK1〗·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.
