金冠苹果花芽大量开始分化时,成花短枝芽内氨基酸总量高于叶芽,成花短枝叶片(花叶)内含量低于叶芽短枝叶片(叶叶)。芽内以天冬氮酸含量最高,叶内以谷氮酸含量最高。芽和叶片内均以中性氨基酸所占比例为最大,酸性氨基酸其次,碱性氮基酸最小。在花芽大量开始分化时,花芽内三类氨基酸均高于叶芽,花叶内含量均低于叶叶,其中碱性氮基酸尤其明显。这时花芽内的天、谷、组、精氨酸占总量的%,两年结果比较稳定,叶芽只谷氨酸比较稳定。金冠苹果成花短枝叶片内氨基酸总量在成花前先上升,随后下降,芽内氨基酸总量相应提高,花芽内含量与花叶含量比值增大,表明叶片供应成花时所需大量氨基酸。此外三种碱性氨基酸,在花芽大量分化前10天内上升幅度大于叶芽,花叶内的含量下降幅度大于叶叶,这些变化也比酸性氨基酸显著,说明碱性氨基酸的动态值得进一步研究。
When the flower buds of Golden Delicious apples began to differentiate in a large number, the total amino acids in the buds and buds were higher than those in the buds. Aspartate nitrogen content in buds is the highest, and the content of glutamic acid in leaves is the highest. The proportion of neutral amino acids in buds and leaves were the largest, followed by acidic amino acids and the lowest in basic amino acids. When flower buds began to differentiate in large numbers, the three types of amino acids in flower buds were higher than those in leaf buds, and the content of mosaic flowers was lower than that in leaf leaves. Among them, basic amino acids were especially obvious. At this time flower bud days, valleys, groups, arginine accounted for% of the total, the two-year results are relatively stable, bud only glutamate more stable. The total amount of amino acids in the leaves of golden crown apples increased first and then decreased, the total amount of amino acids in the buds increased accordingly, and the ratio of the content of flower buds and the content of the mosaic flowers increased, which indicated that a large number of amino acids . In addition, three kinds of basic amino acids in the first ten days before the large-scale flower bud rose more than leaf buds, mosaic leaf content decreased more than leaves, these changes than acidic amino acids significantly, indicating that the dynamic nature of basic amino acids deserves further study.
