不同种源红榉嫁接繁育综合评价
|
摘要
旨在筛选红榉嫁接的最佳方式和适合嫁接繁殖的种源。本研究以7个不同红榉种源优株1～2年生枝条为接穗,以4年生榉树实生苗为砧木,分析插皮接、双舌接、劈接、芽接4种不同嫁接方式的成活率。结果表明:春季嫁接时,枝接方式平均成活率为88.7%,明显优于芽接方式的32.4%,插皮接、双舌接和劈接这3种枝接方式在0.01水平上与芽接差异显著;枝接方式中,插皮接平均成活率最高,为92.4%,但与双舌接和劈接相比,总体无差异;种源间嫁接成活情况分析表明,莒南种源(JN)优株嫁接成活情况最好,平均成活率为90.8%,隶属函数值为90.34%,上海辰山植物种源优株嫁接成活率较低,仅为62.5%,隶属函数值为0.01%。本研究筛选出插皮接这一红榉最优嫁接方式,以及最适合嫁接繁殖的种源——莒南种源。
Aiming at screening out the best way of Zelkova tree grafting and the suitable provenance for grafting and propagation, one or two-year old branches from seven different kinds of Zelkova provenances wereused as scions, and the four-year old Zelkova seedlings were used as stocks. The survival rates of the fourkinds of grafting methods(bark grafting, double tongue grafting, cleft grafting and bud grafting) were analyzed.The results showed that the average survival rate of stem grafting was 88.7%, which had an obvious advantageover bud grafting(32.4%) in spring, bark grafting, double tongue grafting and cleft grafting had significantdifference at 0.01 level with bud grafting. In stem grafting methods, the bark grafting obtained the highestaverage survival rate which was 92.4%, and had no significant difference with double tongue grafting and cleftgrafting. Analysis of survival situation of different provenances showed that the scions taken from Jvnan(JN)had the highest average survival rate, which was 90.8%, and the subordinate function value was 90.34%. Whilethe scions gathered from Shanghai Chenshan Botanical Garden(SH) had the lowest survival rate, which was62.5%, and the subordinate function value was only 0.01%. The study screened out the best grafting way: bark grafting, and the optimal provenance for grafting and breeding: Jvnan.
