- 摘要:
- 以“西扶1号”和“西扶2号”核桃为材料，通过物候观测、果实生长动态测定和落果定期调查，分析了2个核桃品种果实生长模型及生理落果规律。结果表明：“西扶1号”和“西扶2号”核桃果实纵径、横径及线径生长量与其生长时间的关系与Logistic模型高度吻合，相关系数R和决定系数R2都在0.99以上，回归方程统计检验均达极显著水平。“西扶1号”和“西扶2号”核桃均有2次生理落果高峰期，但两者全年生理落果率远低于其它良种核桃；“西扶1号”核桃第2次生理落果高峰不明显，“西扶2号”核桃第2次生理落果数量明显大于第1次。
- Abstract:
- Using ‘Xifu 1’ and ‘Xifu 2’ walnut as materials，through phenologyical observation，dynamic fruit growth measurement and fruit-dropping regular research，growth model and physiological fruit-dropping law of these two walnuts were analyzed.The results showed that longitudinal diameter，transverse diameter and side diameter of ‘Xifu 1-2’ walnut and their growth time were highly consistent with the Logistic Model，the coefficient of correlation R and determination R2 were over 99%，and the statistical test of regression equation also reached significant level；‘Xifu 1-2’ walnut had twice the physiological fruit-dropping peak，but the physiological fruit-dropping rates of these two walnuts throughout a year were lower than other walnut varieties；the second physiological fruit-dropping peak of ‘Xifu 1’ walnut was not significant，while the second physiological fruit-dropping peak of ‘Xifu 2’ walnut was significantly larger than the first time.
