| Abstract: | In order to study the effects of different concentrations combination of plant growth regulators and microorganism agents on quality of tobacco seedlings， new flue-cured tobacco strain 20619 with floating seedlings as the experimental material， different concentrations mixture of sodium nitrophenolate & Bacillus subtilis agent was sprayed on 4 leaves 1 heart of tobacco seedlings， and determined and analyzed main growth and physiological indexes of tobacco seedlings with 8 leaves & 1 heart. The result showed that in 8 leaves 1 heart of tobacco seedlings after sprayed compound of sodium nitrophenolate & Bacillus subtilis agent， its dry matter accumulation content， root activity， chlorophyll content and nitrate reductase activity were better than that of the control， and dry weight （4.98 g·plant-1）， ratio of dry to fresh weight， roots activity （93.01 μg·g-1·h-1）， chlorophyll content （0.548 5 mg·g-1） & nitrate reductase （1.434 U·g-1） of tobacco seedlings were the highest of the treatment of spraied compounding agents of sodium nitrophenolate 20 mg & Bacillus subtilis agent 7.5 g， and activities of catalase， superoxide dismutase， peroxidase and malondialdehyde in leaves were the highest. It showed that spraying the mixture of sodium nitrophenolate & Bacillus subtilis agent on tobacco seedlings is beneficial to improve the quality of tobacco seedlings and cultivating strong seedlings. |
