开花和生理落果与叶片中蛋白质、氨基酸含量变化有密切关系。生理落果高峰,正处于蛋白质急剧分解过程。蛋白质降解愈多,落果愈多。花后的第一次生理落果高峰,占落花落果总数的76.29％,蛋白质降至花蕾到生理落果全程的最低点,是最大的高峰。第二、三次高峰落果数递减。开花和生理落果期间有16种氨基酸:脯氨酸、天门冬氨酸、谷氨酸、亮氨酸较高;其次是甘氨酸、赖氨酸、缬氨酸、精氨酸、丙氨酸、苯丙氨酸、异亮氨酸、丝氨酸、苏氨酸和酪氨酸;组氨酸和蛋氨酸最低。开花前脯氨酸最高,开花至二次高峰一直下降。蛋白质、氨基酸含量变化总趋势一致,波相相反。先是氨基酸积累、氨基酸下降,蛋白质积累、蛋白质下降出现严重的落花落果。
Flowering and physiological drop fruit and leaf protein, amino acid content changes are closely related. Physiological decadent peak, is in the process of rapid decomposition of protein. The more protein degradation, fruit drop more. The first peak of physiological fruit drop after flowering accounted for 76.29% of the total number of fallen drop fruit, the protein dropped to the lowest point of the bud to the physiological drop fruit, is the biggest peak. Second, the third peak decline in fruit. There were 16 kinds of amino acids during the flowering and physiological fruit drop: proline, aspartic acid, glutamic acid and leucine; followed by glycine, lysine, valine, arginine, alanine, benzene Alanine, isoleucine, serine, threonine and tyrosine; histidine and methionine were the lowest. Proline was the highest before flowering and flowered until the second peak had been declining. Protein, amino acid content of the total trend of the same change, the opposite phase. First, the accumulation of amino acids, amino acids decreased, protein accumulation, protein drop serious fall drop fruit.
