摘要: 甜樱桃砧木新品种‘京春1号’为酸樱桃和中国樱桃远缘杂交所得。与常见品种嫁接亲和性好,成活率高,嫁接树有轻微小脚现象。其抗根癌病能力较强,具有一定的矮化性,定植后一般4 ~ 5年可进入盛果期。与‘雷尼’/‘兰丁2号’相比,‘雷尼’/‘京春1号’定植后第5年,株高、横截面积、冠径均低于‘雷尼’/‘兰丁2号’,但单位横截面积产量高于‘雷尼’/‘兰丁2号’。第6年平均单株产量达到16.7 kg。

Abstract: A new sweet cherry rootstock cultivar‘Jingchun 1’was derived from interspecific hybrids of sour cherry(Prunus cerusus)and Chinese cherry(Prunus pseudocerasus). It has very good grafting compatibility with most sweet cherry cultivars,moderate dwarfing ability,and slightly small foot phenomenon. It is highly resistant to crown gall disease. The fully yields of grafting trees can be reached after planting 4–5 years. The tree height,cross-section area and crown diameter of the‘Rainier’/‘Jingchun 1’grafting trees are lower than those of‘Rainier’/‘Landing 2’in the 5th year after planting,whereas the yields based on per cross-section area unit of‘Rainier’/‘Jingchun 1’is higher than that of‘Rainier’/ ‘Landing 2’. The average yield of‘Rainier’/‘Jingchun 1’was up to 16.7 kg per tree in the 6th year after planting.
