Protecting Effects of Various Protective Agent Treatments on Overwintering Sweet Cherry Treelet Shoots Shrivelings in Turpan Area
摘要
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.关键词
