中文摘要：

对不同生态条件下越橘花芽分化进程、花芽量进行调查发现,积温、无霜期、年平均温度是影响花芽分化和花芽量的主要因子。高丛越橘＂蓝丰＂和＂埃利奥特＂、半高丛越橘＂北春＂、矮丛越橘＂美登＂4个品种花芽分化进程在3种生态条件下变化趋势相同,均表现为山东地区最早,吉林地区最晚,辽宁介于二者之间。高丛越橘花芽分化需要较长的无霜期和较高的积温,吉林地区生态条件不能满足其需要,在当年不能完成花芽分化;矮丛越橘＂美登＂物候期最早,生育期较短,在积温高、无霜期长的辽宁、山东地区,该品种出现二次开花现象。

英文摘要：

Flower bud differentiation and number of blueberry were studied in different ecological conditions.The result showed that annual average temperature,cumulative temperature and frost-free period were the main factors,and the progress tendency of flower bud differentiation of four blueberry cultivars in the three ecosystem were the same in different regions.The expression is that the flower bud differentiation of Shandong was the earliest,then Liaoning,and Jilin was the latest. Moreover,highbush blueberry flower bud differentiation needed a long frostfree period and high accumulative temperature.The ecological conditions in Jilin could not satisfy the needs of flower bud differentiation for highbush blueberry,so the flower bud differentiation of highbush blueberry could not be completed in one year.Phenological period of lowbush blueberry ＂Blomidon＂ was the earliest,and growth period was much shorter.The phenomenon of two times′ blossoms appeared in Liaoning and Shandong because of high accumulative temperature and long frost-free period.
