摘要:
1986~1989年在南京对20多个品种的果梅进行田间花期观察和室内测定,结合气温资料分析,结果表明:盛花前60天日平均气温高于0℃的积温值达到230~250℃,即进入盛花期;果梅开花期早而不稳,同品种不同年份盛花期迟早相差可达16~34.5天,梅花0℃左右即能开放,早花年份旬平均气温4℃左右就通过盛花期;果梅花器构造品种间存在差异,多数品种花粉量偏少,花粉发芽率较低;有白花不实和异花授粉不亲和现象;雌蕊退化花的多少主要因品种而异,其次同果枝类型、开花早晚和树体营养有关,不同年份也有差异。这些特性都是果梅栽培和引种应引起注意的。
Abstract:
The results obtained from field observation on the florescence of more than 20 varieties of Japanese apricot during 1986~1989 integrating with air temperature data showed that before blossome the accumulating temperature of day average temperature above 0℃ in 60 days would be 230~250℃. The small amount of accumulating temperature needed for full bloom was one of the reasons for early and unstable florescence of Japanese apricot.There was a difference in flower structure of Japanese apricot between varieties. Most of them were characterized by less pollen, lower pollen germination percentage, self-sterility and cross pollination unaffinity and high ratio of pistil sterile flowers. The responsiblity for the ratio of sterile flowers was mostly dependent on varieties, types of fruit shoots the flowers were on, flowering date, tree nutrition and different years.
