GA_3处理对蒙斯特薰衣草种子发芽的影响
|
摘要
以蒙斯特薰衣草(Lavandula munstead)种子为试材,采用两因素随机区组试验设计方法,研究了GA_3浓度和处理时间对种子发芽及幼苗生长的影响,并应用隶属函数法对各处理组合的发芽效果进行了综合评价。结果表明,GA_3浓度和处理时间两因素的交互效应对发芽势、发芽率、发芽指数和活力指数4个指标的影响达到极显著水平(P<0.01),对苗高和根长2个指标的影响不显著(P>0.05)。两因素对6个发芽指标的影响作用均为GA_3浓度>处理时间。除处理组合5以外,各处理组合分别使种子萌发时间提前1～13 d。蒙斯特薰衣草种子发芽的最优处理为800 mg·L~(-1) GA_3处理6 h,种子发芽率、发芽指数、活力指数、苗高和根长分别达到43.33%,0.394,0.014 9,5.00 cm和2.42 cm。
The seeds of Lavandula munstead were used as experimental materials. Using two-factor randomized block design method, the effects of GA_3 concentration and time on seed germination and seedling growth were studied. The results showed that, the interaction effect of GA_3 concentration and treatment time had a very significant effect on germination energy, germination rate, germination index and vigor index(P<0.01), while the seedling height and the length of root were not(P>0.05). The effects on 6 germination indexes were GA_3 concentration > treatment time. Except for the treatment 5, germination time of the seeds was 1～13 d advanced. The optimum treatment of L avandula munstead was 800 mg·L~(-1) GA_3 for 6 h, whose germination rate, germination index, vigor index, seedling height and the length of root were respectively up to 43.33%, 0.394, 0.014 9, 5.00 cm and 2.42 cm.
