N-苯基-2-萘胺对青菜种子萌发及幼苗生理参数变化的影响
Effects of N-phenyl-2-naphthylamine on the Seed Germination and Characteristics of Physiology Parameters in Chinese Cabbage Seedlings
摘要
Abstract
The seeds of Chinese cabbage were soaked by the various concentrations of N-phenyl-2-naphthyl-amine. The effects of N-phenyl-2-naphthylamine on the seed germination,the growth,the chlorophyll content and the change of antioxidant enzymes in Chinese cabbage were studied in this paper. The results showed that the germination energy and the germination percentage increased with the increase of N-phenyl-2-naphthylamine concentration, whereas they did not have significant difference compared to the control. The change trends of the germination index and the vigor index were the same with the germination energy and the germination percentage. The germination index and the vigor index increased under the lower N-phenyl-2-naphthylamine concentration, but there were no difference compared to the control. When the N-phenyl-2-naphthylamine concentration was less than 1.00 mg/L,the shoot height increased with the increase of N-phenyl-2-naphthylamine concentration. Especially, in the 0.50 mg/L treatment, the shoot height was biggest and had significant difference compared to the control. The trend of the root length change liked as the fresh weight. The root length and fresh weight indicated the trend of increase-decrease with the increase of N-phenyl-2-naphthylamine concentration. Under the lower N-phenyl-2-naphthylamine concentration, the chlorophyll content and antioxidant enzymes activities markedly increased with the increase of N-phenyl-2-naphthylamine concentration. However, the chlorophyll content and antioxidant enzymes activities markedly decreased compared with the control in the higher N-phenyl-2-naphthylamine concentration.关键词
