摘要: 甜樱桃砧木新品种‘京春2号’为酸樱桃(Prunus cerasus)和中国樱桃(P. pseudocerasus)远缘杂交所得。易于繁殖,嫁接亲和性好,成活率高。其耐涝性较强,显著优于‘兰丁3号’‘京春3号’和马哈利(Cerasus mahaleb L.)砧木。具有一定的矮化性,树势弱于乔化砧木‘兰丁3号’,9年干龄‘雷尼’/‘京春2号’的干径为‘雷尼’/‘兰丁3号’的75.7%。嫁接‘雷尼’后表现早果丰产性好,栽植第4 ~ 5年可进入盛果期,‘雷尼’/‘京春2号’嫁接树第6年平均单株产量达到21.8 kg。

Abstract: A new sweet cherry rootstock cultivar‘Jingchun 2’was derived from interspecific hybrids of sour cherry(Prunus cerasus)and Chinese cherry(P. pseudocerasus). It is easy propagation and has very good grafting compatibility with most sweet cherry cultivars.‘Jingchun 2’could keep very slight injury and high survival rate under waterlogging stress,with prominent waterlogging tolerance than ‘Landing 3’,‘Jingchun 3’ and mahaleb(Cerasus mahaleb L.). It has moderate dwarfing ability. The tree diameter of‘Rainier’/‘Jingchun 2’is 75.7% of‘Rainier’/‘Landing 3’in the 9th year after graft. The fully yields of grafting trees can be reached after planting 4–5 years. The average yield of ‘Rainier’/‘Jingchun 2’ was up to 21.8 kg per tree in the 6th leaf year.
