摘要
以雄性不育株宁杞5号和可育株宁杞1号为试材,研究了花蕾发育过程中游离脯氨酸含量、游离氨基酸、可溶性糖、可溶性蛋白质和丙二醛含量的动态变化。结果显示:花蕾发育过程中,宁杞1号花蕾游离脯氨酸和游离氨基酸含量变化均呈先上升后下降的趋势,而宁杞5号花蕾游离脯氨酸含量呈先上升后下降,游离氨基酸呈含量呈持续下降趋势;在花蕾发育各时期,宁杞5号花蕾可溶性糖、丙二醛(MDA)和可溶性蛋白质含量均高于宁杞1号,几种物质含量在宁杞1号和宁杞5号花蕾发育各时期的变化趋势有所不同。
The dynamic changes in the contents of free proline,free amino acid,soluble sugar,MDA and soluble protein in bud of male sterile Lycium barbarum L.,Ning qi 5 and the control,Ning qi 1 were studied.The results showed that the contents of free praline and amino first increased and then decreased during the development of the bud in Ning qi 1.In Ning qi 5,the content of free praline first increased and then decreased too,but the content of amino declined continuously;the contents of soluble sugar,MDA and soluble protein In Ning qi 5 bud were higher than those in Ning qi 1 during the developmental stages,and the trend of content changes of those substances were different.
