The differences of providing amino acid to kernel of different winter wheatculfivars.93-52 with high protein content in kernel had highest content of amino acid innutrition organs,indicated 93-52 can provide abundance material for protein synthesis ofkernel,namely the source in full,so the content of amino acid in kernel was highest;Compared Lumai21 with Jinanl7,the amino acid content in leaf of Lumai21 was a littlehigher than Jinan17,but the amino acid content in stem、sheath and spike was obviouslylower than Jinan17,also the amount of amino acid restored in nutrition organs was large,the translocation degree was low to kernel,namely the flow was not fluency,which wasthe main reason of low content of amino acid in kernel.

小麦不同品种向籽粒供应氨基酸水平的差异。籽粒蛋白质含量高的93-52各营养器官中的游离氨基酸含量均最高，说明93-52籽粒蛋白质合成所需底物供应充足，即源足，因而其籽粒游离氨基酸含量最高。鲁麦21和济南17相比，鲁麦21叶片中的游离氨基酸含量虽略高于济南17，但茎鞘和穗中的游离氨基酸含量却明显比济南17低，并且在后期鲁麦21营养器官中游离氨基酸滞留的多，向籽粒中的转移程度低，即流不畅，是造成鲁麦21籽粒游离氨基酸含量低的主要原因之一。
