| 摘 要： | 为了研究LED光源在设施番茄育苗生产上的精准化利用。该试验以金鹏1号番茄植株为试材,研究了夜间红光处理对番茄植株形态、开花、激素含量和产量的影响,并建立了夜间红光处理次数与番茄株高、茎粗和开花所需时间的生长模型。结果表明,当夜间红光处理次数增加5次及以上时,番茄植株的茎粗和开花所需时间显著增加(P0.05),番茄植株的株高显著降低(P0.05),番茄植株茎叶中的赤霉素3(GA3)和生长素(IAA)含量显著降低(P0.05),番茄植株第1穗果的平均单果质量显著增加(P0.05)。当夜间红光处理次数增加到5次,即每隔2 h打断一次时,番茄植株的株高、茎粗、开花时间、茎叶中IAA和GA3的含量和番茄第1穗果的平均单果质量基本与夜间持续红光处理相一致。因此,可以通过调控夜间红光处理次数来控制番茄幼苗的株高和开花。
