葡萄柚不同砧木嫁接亲和性与保护酶活性相关性分析

Analysis on the Correlation Between the Grafting Affine of Different Stock and Protection of Enzyme Activity in Grapefruit

以"哈路比"为接穗,分别嫁接在"曼赛龙"柚、美国酸橙、当地酸柚、枳壳砧木上,对不同砧木与葡萄柚品种嫁接愈合过程亲和性与保护酶活性的相关性及嫁接愈合过程中保护酶活性变化规律与嫁接成活的关系进行分析。结果表明:"哈路比"与4种砧木嫁接愈合过程中3种保护酶活性大小变化趋势为:愈合部>接穗>砧木;愈合部酶活较高的组合,其嫁接成活率也相应较高;相关性分析表明,愈合部保护酶活性大小与嫁接成活率一样均可作为嫁接亲和性的判定指标;综合多项指标发现,葡萄柚"哈路比"与"曼赛龙"柚嫁接亲和性最高,与美国酸橙和枳壳亲和性一般,与当地酸柚亲和性最差。

With ’Hudson’ for a scion,grafted onto root stock of Citrus grandis var.’mansailong’,C.aurantium Linn,C.grandis aurantium,Poncirus trifoliata（Linn.） Raf respectively,discussed affinity in the process of grafting interspecific of different grapefruit stock and the correlation with protect enzyme activity,the change law of enzyme activity during the healing process of graft and the relationship with survival rate in grafting were studied.The results showed that ’Hudson’ with four than the root stock grafting the healing process three protective enzyme activity for healing the change trend of healing of the ministry〉scion〉stock;The healing the combination of enzymatic activity was higher,the graft survival rate was corresponding higher;The correlation analysis found that healing department protection enzyme activity size and graft survival rate were the same as grafting the judgement of interspecific index;Comprehensive many index think,grapefruit ’Hudson’ and Citrics grandis var.’mansailong’ grafting affine was highest,the C.aurantium Linn and Poncirus trifoliata（Linn） Raf.affine was general,C.grandis aurantium was the worst.
