摘要
为了筛选出适宜青岛市主栽甜瓜品种甜宝嫁接的优良砧木品种,以甜宝为接穗,选择17种砧木品种进行嫁接,对嫁接苗性状进行早期评价。结果表明,黑金刚、京欣砧2号、沐耕719、青农4号和圣砧1号的嫁接成活率均在96%以上;黑金刚嫁接苗的总根长数最多,比自根苗增加104.6%;京欣砧2号的嫁接成活率最高,为98%;沐耕719嫁接苗的株高最高、核酮糖二磷酸羧化酶活性最强;青农4号嫁接苗的茎最粗,比自根苗增加96.4%;圣砧1号嫁接苗的净光合速率和叶绿素含量最高。综上所述,砧木品种黑金刚、京欣砧2号、沐耕719、青农4号和圣砧1号的综合结果较好,可以作为甜宝的嫁接砧木。
In order to select the rootstock cultivars suitable for grafting muskmelon in Qingdao,Tianbao was used as the scion and 17 rootstock cultivars were used for grafting,and the traits of grafted seedlings were evaluated in the early stage.The results showed the grafting survival rate of the rootstocks Heijingang,Jingxinzhen No.2,Mugeng 719,Qingnong No.4 and Shengzhen No.1 were above 96%;the total root length of Heijingang grafted seedlings was the highest,which increased by 104.6%compared with that of the self-rooted seedlings;the grafting survival rate of Jingxinzhen No.2 was the highest,which was 98%;Mugeng 719 grafted seedlings had the highest plant height and the highest ribulose diphosphate carboxylase activity;the stem of grafted seedlings of Qingnong No.4 was the thickest,which was 96.4%higher than that of self-rooted seedlings;the net photosynthetic rate and chlorophyll content of Shengzhen No.1 grafted seedlings were the highest.In conclusion,the rootstock cultivars Heijingang,Jingxinzhen No.2,Mugeng 719,Qingnong No.4 and Shengzhen No.1 had better comprehensive results and could be used as grafting rootstocks for Tianbao.
