摘要
为了探明BR与CCC对夏秋季穴盘番茄苗质的影响,试验配置了不同浓度的CCC以及BR和CCC复配溶液对2叶期番茄苗进行喷施处理,并对处理后穴盘苗的主要形态指标和生理指标进行测定分析。结果表明:夏季各处理与对照相比均有不同程度的壮苗效果,其中单独施用200mg/kg CCC的秧苗效果最好,与对照相比,株高显著下降,根冠比增加,壮苗指数显著升高,G值提高,根系活力增大,叶绿素显著增加,可溶性糖显著提高;秋季各处理也均利于提高秧苗质量,其中施用100mg/kg CCC+0.1mg/kg BR的秧苗壮苗效果最好,与对照相比,株高显著降低,根冠比显著增大,壮苗指数上升,G值显著增加,根系活力增大,叶绿素总量和可溶性糖都显著增加,可溶性蛋白有所下降。
In order to explore effects of BR and CCC on tomato plug-seedling quality in summer and autumn,the plug-seedlings were sprayed with different concentrations of CCC as well as CCC and BR compound solution at two-leaf stage,and morphological indexes and physiological indexes of Plug seedlings were measured and analyzed after treatment.The results indicated that all the treatments did positive effects for improving the seedlings quality compared to control whether in summer or in autumn,and treatment of 200 mg/kg CCC was significantly increased in root-shoot ratio,seedling index,root activity,soluble protein and decreased in height,compared to control in summer,while treatment of 100 mg/kg CCC ＋0.1mg/kg BR was significantly increased in root-shoot ratio,seedling index,chlorophyll,soluble sugar and decreased in height compared to control in autumn.
