摘要
以中熟茎瘤芥品种永安传奇为试验材料,设置光照时长和处理时间两个因素处理,研究短日照对北方温室茎瘤芥生长、瘤茎形成及产量、品质的影响。结果表明:短日照处理可以显著降低茎瘤芥的植株开展度,使茎瘤发生提前,其中6h/10 d处理对茎瘤芥的单株瘤茎质量和茎形指数无显著影响,而且瘤茎粗纤维含量降低,硫代葡萄糖苷含量增加;茎瘤芥瘤茎横径与累积日照时数呈正相关,与日均日照时数呈负相关。
The experiment taking medium maturing tumorous stem mustard variety‘Yonganchuanqi’as test material set up 2 factor treatments including light length and processing time to study effects of short-day conditions on the growth,the tumorous stem formation,yields and qualities of tumorous stem mustard in northern greenhouse.The results showed that short-day treatment could significantly reduce the plant expansion of tumorous stem mustard,promoting stem tumorous occurring early.With the treatment of 6 h/10 d,the weight of tumorous stem per plant and stem shape index appeared no obvious changes,accompanied with crude fiber contents decreasing and glucosinolates contents elevating.Linear regression analysis showed that tumorous stem diameter showed positively and negatively correlated with cumulative sunshine duration average daily sunshine duration,respectively.
