Effects of Different Eggplant Rootstocks on Growth and Development and Insect Resistance of Long Eggplants
In recent years,the production of eggplant in vegetables has been increasing,the occurrence of diseases and pests is also increasing.The grafted eggplant is better than ordinary eggplant in terms of yield,quality,disease resistance and pest resistance.In order to screen the excellent rootstock for eggplant grafting,three varieties such as Solanum torvum Sw.,round eggplant and line eggplant were selected as rootstocks,and long eggplant was used as scion.The grafting survival rate,root neck size,root area,stem diameter,leaf area and insect resistance were measured.The results showed that the grafting survival rate of Solanum torvum Sw.was the highest(100%),the root neck size was thicker,the root area was larger,the leaf area was the largest,the number of leaves was the largest,the plant height was the highest,the weight was the highest,the resistance to whitefly was the strongest,and the death rate was the lowest.All things considered,Solanum torvum Sw.is the better rootstock for eggplant grafting.
