嫁接改造低产榛园平欧杂种榛品种(系)选择研究

Corylus Heterophylla × Corylus Avellana variety optional research by grafting Corylus heterophylla garden with low yield

本试验对平欧杂种榛5个品种(系)在低产榛园嫁接中其嫁接成活率、1 a生枝条发枝量、越冬情况、果实产量等进行调查并观察其亲和性,结果表明:在达维、辽榛8号、1-21(品系)、辽榛3号、玉坠这5个品种(系)中适合作为榛树嫁接的品种为辽榛8号、1-21(品系)、玉坠,其中,辽榛8号、1-21(品系)为最佳嫁接接穗。嫁接第三年产量均达到0.5 kg以上,抗旱、抗寒性较强,亲和性好。

The five different species of Corylus Heterophylla X Corylus Avellana in a low - yield Corylus heterophylla garden were investigated by their grafting survival , preservation rate , the branch seed yield of 1 year , overwintering conditions and fruit production and the grafting compatibility was observed. The result showed that Liaozhen No. 8,1 - 2 1 , Yuzhui were suitable to grafting among the five species. Liaozhen No. 8 and 1-21 were the best. The yield was m3 years. Its drought resisting , cold resistance and compatibility was better.
