摘要
为明确野生李用于巫山脆李砧木的适宜性,本研究对山樱桃、毛桃、野生李和山杏4种砧木嫁接巫山脆李后的成活率、酶活性等指标进行分析,结果表明,毛桃和野生李砧木嫁接苗嫁接成活率、生长量、叶绿素含量、嫁接口愈伤组织中SOD和POD酶活性、亲和性相关基因表达量方面显著高于山樱桃和山杏两种砧木嫁接苗.毛桃和野生李砧木嫁接苗的叶片比叶鲜质量、干质量和砧穗间愈伤组织中不亲和基因相对表达量低于山杏和山樱桃砧木;与山杏和山樱桃相比,毛桃和野生李嫁接口愈合状况良好,无明显不良生长现象.因此,巫山脆李与野生李和毛桃砧木亲和性较高,相对来说,野生李的嫁接亲和性更高,可用于巫山脆李的替代性砧木.
In order to clarify the suitability of wild plum(Prunus salicina Lindl.) used for Wushan crisp plum rootstock.Four kinds of rootstocks of Cerasus tomentosa Thunb.Wall,Amygdalus persica L.Batsch,Prunus salicina Lindl.,and Armeniaca sibirica L.Lam were used to graft the ‘Wushan Crispy Plum’.The survival rate,enzyme activity and other indicators were analyzed.The results showed that the survival rate,scion growth increment,chlorophyll content,SOD and POD enzymes activities and affinity-related gene expression in the callus of grafting union of A.persica and P.salicina were significantly higher than those of C.tomentosa and A.sibirica.While the relative fresh and dry leaf mass,incompatibility gene expression in the callus of grafting union were on the contrary.The callus of grafting union of the previous two rootstocks developed better than that of other two rootstocks.There was no obvious inhibited growth observed.All in all,Wushan crisp plum had higher compatibility with A.persica and P.salicina rootstocks than with the other two rootstocks.The P.salicina is relatively better than A.persica,and can be used as substitute rootstock of famous Wushan crisp plum.
