沙田柚果实生长呈Logistic生长曲线变化,表现为单S形;果实在授粉后12或28天内生长缓慢,此后约2.5个月内迅速生长,之后又逐渐减慢,至6个月时基本停止;果肉的迅速生长始于授粉后约2个月时,持续1.5—2个月,过后渐渐减缓。果实前期的增大主要是果皮的增厚,果肉增大很少。求出果实大小与生长天数的回归方程为(?)=C/(1+e~a+b~x),以这一方程可预测任一时期果实生长发育的状况及其动态指标,进而制订有效的壮果技术措施。
The growth of Shatian pomelo fruit showed Logistic growth curve with single S shape. The fruit grew slowly within 12 or 28 days after pollination, then grew rapidly in about 2.5 months and then gradually slowed down and stopped basically 6 months later. The rapid growth of pulp begins about 1.5 months after pollination about 2 months and then gradually slows down. The increase in the early fruit is mainly the pericarp thickening, the flesh increased rarely. The regression equation of the fruit size and growth days is (?) = C / (1 + e ~ a + b ~ x). This equation can predict the fruit growth and development status and its dynamic index in any period, Effective technical measures of strong fruit.
