Study on Tobacco Growth Promotion of Psoralea Corylifolia L.Extract
The effect of Psoralea corylifolia L. seed extract on tobacco growth was investigated, which provided some theoretical reference for applying Psoralea corylifolia L. seed extract as a plant growth regulator. The influences of different concentrations of Psoralea corylifolia L. seed extract on tobacco growth indexes were investigated by pot experiment. The chlorophyll content and SOD, POD, CAT and other antioxidant enzyme activities of tobacco leaves were determined by physiological and biochemical methods. The results showed that when the extract of Psoralea corylifolia L. Seed extract was diluted by 2000 times, the growth of tobacco was the best, the plant height, aboveground fresh weight, aboveground dry weight, underground fresh weight and underground dry weight of tobacco reached the maximum; and the chlorophyll content and the activities of antioxidant enzymes such as SOD, POD, and CAT in plants were significantly increased.
