越橘果实及新梢生长发育的动态变化

以早、中和晓熟品种“都克”(Duke)、“蓝丰”(Bluecrop)和“埃利奥特”(Elliot)为试材,对不同成熟期的越橘品种在同一生态条件下果实及枝条的各项指标进行测定,研究其果实及枝条在年周期中的变化规律.结果表明:越橘果实的生长变化规律基本一致,总体呈“快速增长-缓慢增长-迅速增长”的趋势；越橘延长枝春梢生长发育动态变化总体呈“快速增长-缓慢增长-停止生长”的趋势；基生枝生长发育动态不同.“都克”与“埃利奥特”基生枝的生长动态一致,呈现“平缓增长-快速增长-缓慢增长”的趋势；“蓝丰”基生枝的生长分为春梢和秋梢2个时期,分别呈现“平缓增长”和“快速增长”趋势.

Fruit and Shoot Growth Trends of Blueberry

The variations of berries and shoots during development of blueberries were studied by testing in the field and laboratory in this experiment,cultivars from early-maturing,mid-maturing and late-maturing during growing season were studied.The results showed that: The variations of blueberry fruits were consistent,which were "rapid growth-slow growth-rapid growth";The variations of bluerry spring shoots were "rapid growth-slow growth-completed growth";The variations of basal shoots were different.The variations of Duke and Elliot basal shoot were consistent,which were "extremely slow growth-rapid growth-slow growth".The growth of Bluecrop basal branches occured in two separate stages,spring and autumn basal shoots were characterized by a period of extremely slow growth and rapid growth.
