摘　　要：我国北方地区春季葡萄抽条现象普遍发生,给生产带来严重影响。试验以‘赤霞珠’一年生枝条为试材,研究壳聚糖(CTS)、羧甲基纤维素钠(SCMC)、海藻酸钠(SA)3种成膜材料对枝条的保水效果。结果表明,同其他品种相比,‘赤霞珠’枝条失水严重,经历越冬后的失水率为13.46%。采用不同成膜剂处理均能提高‘赤霞珠’离体枝条的持水能力,其中0.3%SA效果最好。喷施成膜剂可以减少越冬期‘赤霞珠’枝条含水量的下降率,保水效果由高到低依次为0.2%SA>0.2%SCMC>0.2%CTS。试验表明,采用成膜剂处理能够有效降低‘赤霞珠’枝条水分的散失。The phenomenon of grapevine spring dieback is common in the north of China in spring,which has serious influence on grape production.In this experiment,annual branches of'Cabernet Sauvignon'were used as test materials to investigate water retention effects of three kinds of film-forming materials:chitosan(CTS),sodium carboxymethyl cellulose(SCMC)and sodium alginate(SA).The results showed that compared with other varieties,'Cabernet Sauvignon'annual branches had severe water loss,with a water loss rate of 13.46%after overwintering.Treatments with different film-forming materials could improve water holding capacity of isolated canes of'Cabernet Sauvignon',and 0.2%SA has the best effect.Spraying film-forming materials could reduce water content of'Cabernet Sauvignon'annual branches during overwintering period,and the effect from high to low was 0.2%SA>0.2%SCMC>0.2%CTS.Experiments showed that the treatment with film-forming materials could effectively reduce the water loss of'Cabernet Sauvignon'annual branches.
