【摘要】 以露地栽培为对照,研究大棚栽培条件下翠冠梨果实的生长发育动态规律。结果表明:大棚翠冠梨的果实发育规律与露地栽培基本一致,果径和果重的动态变化曲线为S型,果径的发育存在3个生长高峰,果重有2个增长高峰。大棚栽培的果实发育前期增长较慢,进入果实膨大期后生长速率明显高于露地栽培。大棚栽培的果实生育期要略长于露地栽培。更多还原

【Abstract】 In comparison with those grown in open air,Cuiguan pears in this study is grown in greenhouse.It is indicated that the growth and development regularity of Cuiguan Pear in greenhouse are generally the same as those grown in open air as the dynamic curve of the fruits’ diameter and weight looks like an "S" with three active points of diameter and two active points of weight during growth.The greenhouse-cultivated fruits grow relatively slowly in the prophase,while they develop prominently faster than those in open air after entering the anaphase.The vegetative cycle of the greenhouse-cultivated pears is slightly longer than those in open air.更多还原
