Effects of salt and drought stress on the germination of sage seeds
To define the germination characteristics of sage seeds under adverse situations,the authors had done simulation experiments to research the influence of sodium chloride(NaCl) and polyethylene glycol (PEG6000) with different concentrations on the germination of sage seeds.The results showed that:NaCl and PEG6000 both had restraining influence on sage seeds in different degrees,which caused the decline of seeds' germination rate,germination power and germination index.Under the stress of 0.10 mol/L NaCl solution,the highest germination rate and power were 88.33% and 66.67%,respectively;when in the solution of 0.40mol/L concentration,the seeds could not germinate.Under the stress of 4% PEG6000 solution,the highest germination rate and power were 81.67% and 66.89%,respectively.These results indicated that the sage seeds can normally germinate in mild salt soil,but in heavy salt soil the germination ability of sage seeds will be lost.
