翻译：三种砧木资源都具有良好的抗逆性适合大多数地区栽培。其中八棱海棠和山荆子的扦插生根能力较强在适宜的条件下扦插生根率可以达到50以上具有直接利用于产业生产的潜力。在童期内的楸子扦插生根能力强生根率可以达到80但缺乏对成年期楸子扦插生根能力的研究对楸子的扦插生根能力还不明确。

All three types of rootstock resources have good resistance and are suitable for cultivation in most areas. Among them, the eight-angled crabapple and mountain ash have strong ability to root from cuttings, and under suitable conditions, the rooting rate can reach more than 50%, with the potential for direct use in industrial production. The rooting ability of young elm trees from cuttings is strong, and the rooting rate can reach 80%, but there is a lack of research on the rooting ability of adult elm trees from cuttings, and the rooting ability of elm trees is not yet clear.
