摘要
通过对同一果园"妃子笑"荔枝连续5 a的果实发育期物候资料及同期温度等气象资料的对比分析,发现不同年份"妃子笑"荔枝果实成熟期早晚及果实全发育期与日生长温度高低关系密切:花序-果肉出现期间,日生长温度偏高的年份果实发育进程快,发育期间隔天数短,反之亦然;而果肉出现-可采成熟期间隔天数相对稳定。因此,果实成熟期早晚主要受花序-果肉期生长温度的影响。有关积温统计结果表明,"妃子笑"荔枝果实发育期间的有效生长积温更能反映温度条件对荔枝果实发育进程的影响。研究结果对开展"妃子笑"果实成熟期预报服务有积极意义。
Based on the phonological data of the fruit development of the Litchi （Litchi chinesis Sonn. ） Feizixiao and the meteorological data in the same periods for the last five years in Lingshan County of Guangxi Autonomous Region, the relationships between the fruit development of Litchi Feizixiao and the temperature conditions were analyzed. The results showed that the fruit maturity period and the full development period were closely related to the daily growth temperature in the different years. The process of the fruit development would be accelerated and the length of the growing period would be shortened with higher daily growth temperature in duration from floral bud to pulp appearance stage, whereas the fruit development process would be delayed and the growing stage would be longer. However, the days from pulp appearance stage to the fruit maturity stage were relative stable. The results of the statistical analysis indicated that the effective accumulated growth temperature could better reflect the temperature influence on the fruit development process. This research result would provide the reference to the prediction of the Litchi fruit maturity period.
