摘要
为了拓宽综合应对苹果花期低温冻害的渠道,在现有的防冻措施上取得新成效,该研究通过喷施9个浓度的脱落酸延迟苹果花期,其中以105、120mg/L处理喷施3次的效果最好,苹果初花期推迟三四天,盛花期推迟一二天,落花期推迟1d;但对雌蕊败育有一定影响。
To broaden the channels for comprehensive responses to low-temperature frost damage during apple blossom period and achieve new results in existing frost prevention measures,this study investigated the effects of spraying abscisic acid at nine concentrations across three gradients to delay the flowering of Red Fuji apples,the most significant effect was observed after three sprays at concentrations of 105 mg/L and 120 mg/L,which could delay the initial flowering period by 3~4 days,the full flowering period by 1~2 days,and the falling flower period by 1 day,without significantly adverse effects on the quality of flowers compared to the control group.
