不同砧木嫁接对番茄生长及品质的影响

Effects of different rootstocks on the growth and quality of tomato

为了探讨不同砧木嫁接对番茄产量和品质的影响,以’粉霸2000’番茄为试验材料,选择’美砧一号"砧霸一号’’托鲁巴姆’’强力砧’’新纳姆’5个砧木品种进行比较试验,’美砧一号’砧木嫁接番茄成活率达90.67%,果实品质与对照无显著差异,单果质量0.24 kg,667 m^2产量7 002.79 kg,比自根苗分别增加了41.17%,58.97%。综合评价认为,’美砧一号’砧木嫁接番茄不仅成活率高,而且能显著促进植株生长,提高番茄产量,可作为番茄嫁接砧木选择的参考品种在盐城地区推广。

In order to study the effects of different rootstocks on the yield and quality of tomato,five different rootstocks(’Meizhen No.1’,’Zhenba No.1’,’Solanum torvum’,’Qiangli zhen’ and ’Xinnamu’) were applied to perform the comparative test in this research,the tomato variety ’Fenba2000’ from Zhengzhou Zhengyan Seedling Technology Co.,Ltd.was used as scion.The result showed that the survival rate of tomato seedlings grafted by ’Meizhen No.1’ was90.67%,but there was no significant difference in fruit quality when compared with the self-rooted seedlings.The average fruit weight was 0.24 kg and the yield per 666.7 m2 was 7 002.79 kg,which was 41.17% and 58.97% higher than these of the control,respectively.According to the comprehensive evaluation,when ’Meizhen No.1’ was used as rootstock,the survival rate of grafted seedlings was increased,the plant growth and yield were improved,so it could be used as the reference rootstock variety for tomato in Yancheng area.
