Abstract为探究植物先花后叶的影响因素,本研究以1963-1988年间北京地区杏和山桃展叶和始花物候资料及相应的日最高、最低温度数据为基础,利用偏最小二乘回归法确定杏和山桃叶芽及花芽的需冷期和需热期,进而利用动态模型和生长度小时模型分别估算叶芽和花芽的需冷和需热量。结果表明,依据长期物候观测资料,利用偏最小二乘回归法进行植物需冷和需热量的估算非常有效。先花后叶植物叶芽和花芽需冷量几乎相同,需热量的差异是导致植物先花后叶的主要原因。杏和山桃花芽的需热量分别为2 829.7±876.2和1 457.2±581.2生长度小时,而相应叶芽需热量却是花芽的两倍之多。基于物候观测的重要性及实用性,中国物种水平上的地...
