Effects of different solutions on germination potential,germination rate and germination index of Chinese cabbage
In order to meet the requirements of the sowing production and solve the problems of irregular emergence,lack of seedlings on the Chinese cabbage,this study compared the differences on the germination potential,germination rate and ger-mination index of Chinese cabbage vegetable Shanghaiqing','Jingguan rape','Jinbeibei with different solutions(2.5％Sodium chloride,350×X wood vinegar and 60 × Compound fertilizer).The results showed that the GP,GR and germination index of'Shanghaiqing'were increased by 10.27％,9.85％and 22.17％,but the effects were not obvious on'Jingguan rape'and'JinBeiBei'.The GP,GR and germination index of'Shanghaiqing'were significantly increased treated with wood vinegar(350×)and compound fertilizer(60×)(containing wood vinegar)for 2 h and 4 h.Priming by compound fertilizer(60×)had a best effect.Compared with the control,the GP,GR and germination index were increased by 10.27％,8.62％and 21.02％respectively,and reached 0.967,96.67％,97.94.The GR of'Jingguan rape'was remarkable increased by 4.3％when it prim-ing with 2.5％NaCl.And the germination index was remarkable increased by 8.9％when it priming with wood vinegar(350×).However,there had no impact on the GP,GR,germination index of'Jinbeibei when it priming by three different solu-tion.At the same time,through inter-subject effect analysis,varieties play a significant role in GP,GR and germination index.The germination indexes of three kinds of vegetables were significantly increased by the priming effect of different solutions and the interaction effect between varieties and different solutions.
