龙眼果实生长曲线和各组织的相关分析

龙眼以全果干鲜重、体积、纵横径表示的Ｌｏｇｉｓｔｉｃ生长曲线，其回归方程经Ｆ检验，达极显著水平，简单相关、偏相关、通径分析统计表明，直接影响龙眼果实生长主要是假种皮和果皮，而假种皮与种子的偏相关达显著水平．龙眼果实及各组织的生长型，不论以鲜重或干重表示，均为单Ｓ型．龙眼果实及各组织的水分进入均早于溶质的进入，假种皮的生长落后于果皮和种子的生长，溶质进入果皮和种子先于假种皮，花后７０ｄ开始，溶质主要进入假种皮．

The Growth Curve of Longan Fruit and the Correlative Analysis of Its Tissues

The logistic growth curve,demonstrated by dry and fresh weight,volume,longitudinal and cross diameter of whole long fruit ,come up to extremely significant level as a result of F test.Through simple correlation,partial correlation and path analysis .It was found that the main factors effectting the growth of longan fruit Were the aril and the peel .The partial correlation between the aril and the peel reached significant level .The growth curves of longan fruit and its tissues,demonstrated by either dry weight or fresh weight ,were all single S trpe,Water entered longan fruit and its tissues earlier than solute did.The growth of aril falled behind the growth of peel and seeds.Solute entered peel and seeds earlier than entere aril .Seventy days after blossoming ,solute mainly entered aril.
