| 摘 要： | 用高效液相色谱法（HPLC）测定了苹果幼树枝条在春季、夏季刻芽后内源激素的含量变化，调查了不同处理的萌芽成枝率。结果表明：（1）春季刻芽后长富2号芽体中的GA3含量显著增加，ABA含量显著降低，GA3／ABA比值由0．21提高到2．56，枝条的萌芽成枝率也显著提高（P＜0．05）；（2）夏季刻芽后，长富2号和首红枝条芽体中GA3、IAA及ZT含量均显著提高，ABA含量显著降低，GA3／ABA比值由对照的2．21提高到10．73，萌芽率增高到83．65％，3年生树的全园枝量接近于盛果期的枝量指标。

| Abstract: | Changes of endogenous hormone in apple shoot with bud-notching treatments were measured by HPLC, and the shoot sprouting percentage was investigated in the same time. Results showed that (1) the contents of GA3 in the bud of Naganofuji No. 2 apple variety notched in spring raised sharply, but ABA content decreased, and the ratio of GA3/ABA increased from 0. 21 to 2. 56, and the sprouting percentage was significantly higher than that of control; (2) the contents of GA3, IAA and ZT in the bud summer notched also increased greatly, but ABA content decreased sharply, the ratio of GA3/ABA changed from 2. 21 to 10. 73, and sprouting percentage reached 83.65% in a three-year-old orchard when bud-notching treatment was applied, and the total number of shoot and spur approached to the number required for a maximum crop load in the future. |
