摘　　要：为筛选出适宜浙南地区番茄壮苗培育的植物生长调节剂,以不同浓度的YELVSU P2-37、多效唑、矮壮素、壮苗1号处理番茄砧木品种浙砧7号和接穗品种红樱1号,研究植物生长调节剂对番茄穴盘育苗的影响。结果表明,不同植物生长调节剂对不同品种番茄的处理效应不同,除对红樱1号茎粗、地下部干重和展叶宽无显著影响外,不同植物生长调节剂对红樱1号和浙砧7号的其他指标都有显著影响。所有生长调节剂对番茄株高都有抑制作用,但对其他指标不同生长调节剂作用不同。对于红樱1号,0.2 g·L^(-1)YELVSU P2-37处理的各生物量指标最高,同时种苗质量也最佳,为该品种壮苗培育的最佳植物生长调节剂;对于浙砧7号,0.13 g·L^(-1)YELVSU P2-37处理植株形态和种苗质量均为最佳,为该品种的推荐植物生长调节剂和适用浓度。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.
