摘要
‘中矮5号’是从‘锦香’梨实生后代中选育出的梨矮化砧木新品种。树体矮化紧凑,1年生株高相当于乔化型‘早酥’梨的17.3%。作中间砧与嫁接品种和基砧亲和性好,矮化程度、早果性及丰产性明显高于无中间砧对照。较抗梨枝干轮纹病和梨干腐病,抗寒性较强,在辽宁兴城地区无冻害,适于在辽宁中南部梨栽培区应用。
‘Zhongai 5＇ is a new pear dwarfing rootstock variety which was selected from the seedling progenies of ‘Jinxiang＇. It is dwarf and compact,and one year old tree is about 17.3% height of the vigorous‘Zaosu＇pear tree. As interstock,it had a good compatibility with rootstocks and scions,and it could evidently make the grafted tree more dwarfing,earlier fruiting,and better harvest.‘Zhongai 5＇ has a good resistant to pear branch ring rot and rot disease. It is hardy and there is no freeze injury around Xingcheng aeres of Liaoning Province. It is suitable for using in the central and south areas of Liaoning Province as dwarfing interstock.
