翻译：三种砧木资源都具有一定的耐旱性耐涝性和耐瘠薄能力。其中丽江山荆子缺少扦插生根的研究其扦插生根能力还不明确。小金海棠变叶海棠都有较强的扦插生根能力明确其扦插生根的适宜条件和扦插生根周期对这两种砧木在生产是直接利用具有重要意义。虽然扦插生根能力较强但这些砧木的抗逆性并不突出难以在环境更恶劣的地区利用。因此可以作为扦插生根性强的亲本与抗逆材料进行杂交选育

Translation: The three types of rootstock resources have certain drought resistance, waterlogging tolerance and barrenness tolerance. Among them, the Lijiang Mountain thorn lacks research on cutting and rooting, and its ability to cut and root is not clear. The small golden crabapple and the variegated crabapple have strong cutting and rooting ability. Clarifying their suitable conditions and cutting and rooting period is of great significance for the direct utilization of these two types of rootstocks in production. Although they have strong cutting and rooting ability, their resistance to adversity is not outstanding, making it difficult to use them in more adverse environments. Therefore, they can be hybridized and bred with parents with strong cutting and rooting ability and stress-resistant materials.
