【摘要】 小金海棠根系发达,固地性好,耐瘠。具有抗旱、抗寒、耐涝等多种抗性,是极重要的“种质”资源。以小金海棠为砧木嫁接的40个苹果品种,均表现嫁接亲和力好,树苗生长健壮。对金冠/小金海棠17年生嫁接树的调查表明,小金海棠具有一定的矮化效应。小金海棠属四倍体(2n=4x=68),具有无融合生殖特性,用作实生繁殖,苗木整齐一致。也可用实生苗压条扩大繁殖系数.更多还原

【Abstract】 This paper is a report of Malus xiaojtnensis Chenget Jiang,whichcan be used as a stock of apples.Our investigation shows that theroot system of M.xiaojinensis is flourishing and fixes firmly in theground.M.xiaojinensis has many anti-properties such as drought-resis-tant cold-resistant,water-resistant and poor-soil-resistant.It is oneof the important germplasm resource.M.xiaojinemis,as a stock,on which we grafted fourty apple var-ietes.Their affinity shows pretty good.The young trees grow upvigorously.Observation on a grafter(Golden delicious/M.xiaojin-ensis),which has grown for seventeen years,shows that M.xiaojin-ensis has some dwarfing effect.M. xiaojinensis is a tetraploid(2n=4x=68).It has apomixischaracteristics.When it reproduces by seed,its nursery stock is tidyand unanimous.It reproduces also by layering in order to extend itsreproduction coefficient.更多还原
