【摘要】 对涩柿本地优良品种 (于都盒柿 )和甜柿引种优良品种 (松本早生富有 )果实发育中的单果鲜重、干重、萼片干重及单位重量内不同糖的含量进行测定。建立单果鲜重生长模型为 :松本早生富有 :^Y =- 0 .0 0 14X2+1.176 5X +4 .36 76 ,R2 =0 .99;于都盒柿 :^Y =- 0 .0 0 0 9X2 +0 .9949X - 1.973 5 ,R2 =0 .9793。分析干、鲜重生长节律得出两品种果实膨大高峰期的出现有时间差 ,故田间管理需区别对待。建立收获模型 (收获三指标鲜重、干重、萼片干重的关系模型 ) :^V =17.8782 2 +0 .2 35 17X1- 15 .385 77X2 ,R =0 .972 88。发现萼片重对干重增长有促进作用且为主导因子 ,对两品种不同测定项作多指标方差分析 ,结果表明两品种的收获三指标、三种糖含量差异显著 ,松本早生富有果实品质优于于都盒柿更多还原

【Abstract】 A growth model was established for local astringent persimmon (Diosyros kaki L. c. v. yuduheshi) and introdudional sweet persimmon (Diosyros kaki L. c. v. Matsumoto wase Fuyu), Data were measured on fresh weight, sepal dry weight, dry weight and different contents of sugar in the percent weight in different growth stages. The growth model is a dynamic equation as follows:=-0.0014X 2+1.1765X+ 4.3676 ,R 2=0.99; for Diosyros kaki L. c. v. Matsumoto wase Fuyu; =-0.0009X 2+0.9949X- 1.9735 ,R 2=0.9793 for Diosyros kaki L. c. v. yuduheshi. According to the analysis on the rate of fresh and dry weight growth, there is a difference between the two varieties in maximum peak of expansion. Different methods should be taken in field management. A harvesting model, which is the relation model of fresh weight, dry weight and repal dry weight, was established. It is as following:=17.87822+0.23517X 1-15.38577X 2,R=0.97288. It was discovered that the repal weight is the major factor of dry fruit weight. Through variance analysis on multipie factors obvious differences were observed in fresh weigh, dry weight, repal dry weight and ontent of sugar. Diosyros kaki L. c. v. Matsumoto wase Fuyu is superior to Diosyros kaki L. c. v. yuduheshi in qulity.更多还原
