摘要
欧李基生枝生长势显著强于一级枝，４５ｃｍ以下株高有利于保持植株的旺盛生长，枝位低新梢生长量较大，枝位高枝条密度较大，枝条具有较高的萌芽率和成枝力。新梢生长呈连续状态，８月上、中旬基本停止生长。单叶面积增长呈一次高峰，并持续１５ｄ左右。总叶面积增长呈现“单Ｓ型”曲线。果实生长呈“双Ｓ”曲线，果实生育期一般在８０～１００ｄ左右。欧李枝条在冬春有抽条现象。
The growth vigor of basal shoots was significantly stronger than that of first ordershoots,The plant height that was shorter than 45 cm was favourable to vigorous growihof plant.The increment of new shoots was greater in low position,and the shoots densitywas larger in upper position,The shoots showed higher germination rate and branchfornllng power。 The growth of shoot was continuous at first,and finally in the withhold。ing stage at early and middle in August.The increase of single leaf area showed onepeak, with sustaining l 5 days or so。 The increase of total leaves area showed curve ofsingle S pattern。The growth of fruits showed double S curves,with generally sustainingabout 80～100 days,The shoots appeared sprout in winter or spring。
