Effects of different plant growth regulators on tomato plug seedling in southern Zhejiang
In order to screen the suitable plant growth regulators for the cultivation of strong tomato seedlings in southern Zhejiang,tomato rootstock variety Zhezhen 7 and scion variety Hongying 1 were treated with different concentrations of YELVSU P2-37,paclobutrazole,cycocel and Zhuangmiao 1 to study the effect of plant growth regulator on tomato plug seedlings.The results showed that different plant growth regulators had different effects on different tomato varieties,except for no significant effects on stem diameter,underground dry weight and leaf spread width of Hongying 1,different plant growth regulators had significant effects on other indexes of Hongying 1 and Zhezhen 7.All growth regulators had inhibitory effects on tomato plant height,but they had different effects on other indexes.For Hongying 1,the highest biomass indicators and the best seedling quality were observed in the 0.2 g·L-1 YELVSU P2-37 treatment,making it the best plant growth regulator for the cultivation of strong seedlings in this variety.For Zhezhen 7,0.13 g·L-1 YELVSU P2-37 treatment showed the best plant morphology and seedling quality,making it a recommended plant growth regulator and suitable concentration for this variety.
