- Abstract:
- To study the effect of low concentration of sodium chloride in nutrient solution on the growth of Brassica campestris,two experiment stages had been set:the seed germination test,five concentration gradients （0-20 mmol·L-1） of NaCl were set in soaking treatment.The germination rate,germination index,vigor index and growth index of cabbage were measured;the cultivation test of Brassica campestris in nutrient solution,six concentrations （0-25 mmol·L-1） of NaCl in the nutrient solution were set up in treatments,the growth index and quality index of cabbage were measured.The results showed that in the seed germination test,10 mmol·L-1 NaCl treatment was better.The germination rate,root length,stem length and total fresh weight of cabbage were 3.58%,23.64%,13.88%,33.48% higher than CK respectively;in the nutrient solution cultivation experiment,10 mmol·L-1 NaCl treatment of Brassica campestris seedling growth was better.The increase of root length,stem length and fresh weight were 53.96,39.87,97.39 percent points.The contents of vitamin C and soluble sugar were increased by 22.24% and 46.44%,respectively.The contents of vitamin C and soluble sugar increased first and then decreased with the increase of NaCl concentration,the highest group was 10 mmol·L-1 treatment.The cellulose content were 6.25-6.80 mg·g-1,with the increase of NaCl concentration,the difference was not significant.The soluble protein content of Brassica campestris was the highest in 5 mmol·L-1 treatment of NaCl.From the test results could be concluded,5-10 mmol·L-1 NaCl solution could not inhibit the seed germination rate and seedling growth;the addition of 5-15 mmol·L-1 NaCl could not inhibit the growth of Brassica campestris seedlings and the quality of Brassica campestris.Keywords:Brassica campestris L．ssp. pekinensis (Lour) Olsson;NaCl;seed germination;nutrient solution cultivation;growth;quality
