Abstract:
Fermentation solution of Penicillium oxalicum was used as research object,via germination test,the influence of Penicillium oxalicum HB1 on the germination rate,seedling growth and root tolerance index of cucumber (Cucumeris),pepper (Purus) and cabbage (Seres brassica) seeds was studied to provide reference for the high quality vegetable seedling.The results showed that the fermentation solution of Penicillium oxalicum HB1 diluted for 106 times enhanced the germination of cucumber and pepper seeds and seedlings growth.The germination rates reached 100.00% and 98.67%,which were 1.18 times and 1.05 times higher than that of the control.The relative seedling height and root tolerance index for cucumber and pepper were 194.43%,173.72% and 125.62%,104.90%.For the cabbage seeds,the suitable level of fermentation liquid of Penicillium oxalicum HB1 was diluted to 107 times.The germination rate was 92.00% and 1.01 times higher than that of the control.The relative seedling height and root tolerance index were 140.50% and 144.45%.These indicated that low level of Penicillium oxalicum HB1 fermentation solution diluents was helpful to improve the seed germination rate,promote the growth of vegetable seedlings.The promotion of fermentation liquid for Penicillium oxalicum HB1 diluted to 106 times on cucumber and pepper seeds germination and seedlings growth was the most significant,and fermentation liquid diluted for 107 times for cabbage seeds.
