树莓越冬性试验研究初报

单  位：
沈阳农业大学园艺系
关键词：
树莓;低温处理;抗冻性;越冬抽条
摘  要：
在沈阳地区，将树莓越冬枝条分别在－２０，－２５，－３０，－３５，－４０℃的低温处理后，采用电导法，解剖观察及温室水培发芽试验，来鉴定树莓抗冻性。结果表明，树莓越冬枝条在－３０～－３５ ℃条件下遭受冻害，而致死临界温度是在－４０℃以下。越冬枝条失水状况调查结果表明，树莓枝条在越冬期间抽条现象较为严重，为树莓越冬的主要伤害。

关键词：
raspberry; treated by low temperature; overwintering ability; physiological drought by waster losing in winter
摘  要：
The overwintering canes (shoots) of raspberry in Shenyang area were treated under the temperature of -20, -25,-30, -35 and -40℃ for 24 hours, then their cold resistance ability was evaluated by electrical conductivity, ~anatomical structure and sprouting rate under solution culture in plastic greenhouse. It was found that the overwintering shoots of raspberry were damaged from -30℃ to -35℃, but their criical temperature for death are about -40 ℃ By measuring the losing water quantity during the dormant period, it ~ found that the physiological drought by weter losing of the tested shoots was the main injury for the raspberry shoots in winter.
