Title: Effects of Growth Regulators on Autumn Tomato Plug-seedling and High-yielding Characters
Abstract: The effects of six different plant growth regulators on the seedling physiological indexes,vegetative growth and yield of tomato were investigated in greenhouse in autumn,by pouring them to tomato roots at seedling stage.The results showed that the ABT rooting powder treatment significantly increased the qualities of tomato seedlings,and the Bihu,Jinyunda-120,sodium nitrophenolate and chitin treatments increased the plant height,stem diameter,leaf area,root-shoot ratio,G-value,sound seedling index(SSI) and chlorophyll content of tomato seedlings in different range.After planting,all the growth regulator treatments increased the plant vegetative growth and the numbers of tomato bud,and the ABT rooting powder treatment was significantly increased the yield at early stage,weight of a single fruit and total yield of tomato.In conclusion,applying the 100-fold concentration of ABT rooting powder was optimum for growth of autumn tomato seedlings in greenhouse at one-leaf stage.
