库尔勒香梨三个芽变品系的生长结果特性观测

[目的]研究库尔勒香梨芽变品系的生长结果特性.[方法]以库尔勒香梨及几个芽变品系沙01、芽变6号和芽变9号为试材,在库尔勒市3个果园进行试验.于2008、2009年观测了试材的主要物候期;观测了试材1年生新稍、果实和叶片的纵、横径.[结果]3个芽变品系的花期要比香梨早1周左右,采收期要比香梨早1个月;果实的纵、横径均大于香梨果实,新稍长度芽变9号、沙01大于香梨新稍,芽变6号小于香梨;叶片面积均大于香梨,叶绿素含量芽变6号大于香梨,其余两个品系与香梨无显著差异.[结论]库尔勒香梨芽变品系在物候期和生长结果特性上存在差异,能够为库尔勒香梨的3个芽变品系栽培管理提供理论和实践依据.

Obeservation of Growing and Bearing Habits of Three Bud-sport Strains of Korla Fragrant Pear

[Objective]The research was carried out in three orchards of Korla fragrant pear,whose materials were Korla fragrant pear and its bud-sport strain,[Method]Using Sha01,bud-sport 6,bud-sport 9 as test materials.The main phenophase and one-year-born treetop as well as transversal and vertical stem of fruits and leaf blades were observed.[Result]The result showed that flowering period of three bud-sport strains were about one week earier and the harvest period was one month earier than that of Korla fragrant pear;transversal and vertical stem of fruits were larger than that of Korla fragrant pear;the length of new treetop of bud-sport 9 and Sha01 were both larger but bud-sport 6 was smaller than that of Korla fragrant pear;the leaf area of three bud-sport strains were bigger than that of Korla fragrant pear,the content of chlorophyll of bud-sport 6 was bigger than that of Korla fragrant pear,but another two strains did not have significant different with Korla fragrant pear.[Conclusion]There were differences between phenophase and bearing habits of bud-sport strains of Korla ffagrant pear,which can provide theoretical and practical foundation for cultivation and management of three bud-sport strains of Korla fragrant pear.
