Abstract: [Objective] In this article,the protecting effects of sweet cherry sapling from shoot shrivelling among various protective agent treatments in Turpan area were studied in order to provide a theoretical basis for improving sweet cherry sapling survival rate after winter in this area.[Method]3 years old'Bin-ku with Mahari'and'Yan-yang with Mahari'shoot and stock combination as materials,setting 4 protective agent treatments: Fang-chou-bao,Jing fang-yi-hao,methylcellulose and poval,using no-treatment as CK,altogether there were 10 treatments with two varieties.The water content(total water content,free water content and bond water content)in annual shoots with various treatments during winter period was determined,the value of'bond water content/free water content'was calculated and the shoot shriveling rate and index were investigated.Furthermore,the hydraulic force of excised branches in vitro was determined by laboratory test.[Result]The results showed that in Turpan area,the shoot shriveling resistance ability was related to varieties,Yan-yang was better than Bin-ku.All protect agents that we had used resulted in good protect effects,isolated shoots with all protective agents had high water-holding capacity.Water loss rate reduced with all protecting treatments during winter,the bond water content and the value of'bond water content/free water content'were enhanced with all protect treatments,shoot shriveling rate and index obviously decreased with all protect treatments after winter.Protecting effect from high to low in turn was Fang-chou-bao,Jing fang-yi-hao,methylcellulose and poval.Early to middle February is the critical period of shoot shriveling in Turpan.[Conclusion]In Turpan area,the sweet cherry variety Yan-yang have good shoot shriveling resistance and the application of protective agent during winter time can effectively reduce the shoot shriveling rate and strip index of sweet cherry.Among them,Fang-chou-bao and Jing fang-yi-hao have quite good protecting effect.

摘要： [目的]研究不同防护剂对吐鲁番地区甜樱桃幼树越冬抽条的防护效果,为提高新疆吐鲁番地区甜樱桃越冬成活率提供一定的理论依据.[方法]以3年生滨库+马哈利和艳阳+马哈利两组甜樱桃砧穗组合为研究对象,分别设置越冬期喷施防抽宝、京防一号、甲基纤维素、聚乙烯醇四个处理,以不进行喷施作对照(CK),共10个处理组合,分别测定和调查越冬期间枝条含水量(总含水量、自由水含量、束缚水含量及束缚水/自由水)、越冬抽条率和抽条指数;进一步通过室内试验,测定不同处理离体枝条持水力.[结果]不同甜樱桃品种抗抽条能力存在一定差异,艳阳抗抽条能力高于滨库;在吐鲁番地区,采用不同防护剂处理均能提高甜樱桃离体枝条的持水能力,降低越冬期枝条的失水率,提高枝条束缚水含量及束缚水与自由水比值,并能显著降低越冬抽条率和抽条指数,均能起到较好的防护效果,防护效果由高至低依次为防抽宝、京防一号、甲基纤维素和聚乙烯醇.2月上旬至中旬是吐鲁番地区甜樱桃抽条发生的关键时期.[结论]在吐鲁番地区,艳阳抗抽条能力较强;越冬期间采用防护剂处理能够有效降低甜樱桃的抽条率和抽条指数,其中防抽宝和京防一号的防护效果较好.
