The sorghum seeds' germination and its seedlings' growth reacted to the stresses from NaCl and Na2CO3 in different concentrations(0,50,100,150,200,300 mmol·L-1) was researched.The results showed that the germination rate of sorghum seeds decreased with the increase of the salt-alkaline concentration,in which the germination rate of the sorghum seeds processed by Na2CO3 decreased significantly greater than NaCl.The growth potential of seedlings showed significant negative correlation with both salt and alkal...
