摘要: 为了研究山西省部分甜樱桃主栽品种的需冷量,为山西省设施甜樱桃扣棚和升温时间的确定提供参考,试验以9 个山西省甜樱桃主栽品种‘红玛瑙’、‘红灯’、‘龙冠’、‘龙旭’、‘大紫’、‘美早’、‘雷尼尔’、‘早大果’、‘拉宾斯’为材料,在甜樱桃开始大量落叶时采集枝条进行低温处理,将低温积累到一定时间的甜樱桃枝条置于适宜条件下培养,3周后统计萌芽率,采用“0 ~ 7.2℃ 模型”对其需冷量进行分析。结果表明:不同甜樱桃品种需冷量有差异,供试品种的需冷量值集中分布在500~750h;部分甜樱桃品种存在芽类间需冷量不同的现象;同一品种其需冷量与物候期没有相关性。

Abstract: To provide certain references on sweet cherry cultivation in greenhouse, chilling requirements of 9 sweet cherry cultivars were calculated using 0-7.2℃ model. The branches of‘Hongmanao’,‘Hongdeng’, ‘Longguan’,‘Longxu’,‘Black Tartarian’,‘Tieton’,‘Rainier’,‘Крупноплодная’,‘Lapins’were collected in Shanxi Province, and their chilling requirements were estimated after low- temperature treatment. The results showed that, chilling requirements were different among the 9 cultivars, and ranged from 500-750 h. Moreover, there were differences between the chilling requirements of flower bud and leaf bud in some cultivars, and there was no obvious correlation between chilling requirements and fruit development period.
