甜柿砧穗组合嫁接亲和力研究

用数种砧木对引自日本的16个甜柿品种进行嫁接亲和力比较试验,并辅以同位素示踪和嫁接苗生长情况的观察,结果表明,用君迁子和浙江省的几种野柿作完全甜柿砧木,多有不亲和现象出现,而作不完全甜柿的砧木,则多数表现亲和性良好。从浙江省的野柿中选出77号和56号两种类型,可作‘前川次郎’和‘一木系次郎’等完全甜柿的砧木,嫁接亲和力良好。

The Graft Compatibility of Different Rootstock-scion Combinations of Sweet Persimmons

The experiment was carried out to study the graft compatibility between various rootstocks and 16 cultivars of Japanese sweet persimmons by isotope trace technique and observing the growth condition of grafted seedlings. The results showed that most cultivars of perfectly sweet persimmons were incompatible when grafted with the rootstock of Date plum and several wild persimmons in Zhejiang province, but most cultivars of inperfectly sweet persimmons were compatible. The graft compatibility of No. 56 and No. 77 which were selected from the wild persimmons in Zhejiang province was excellent when grafted with Maekawa Jiro and Ichikikei Jiro.
