Abstract:
Taking five varieties of cucumber seeds as materials,the effects of different concentration NaCl stress treatments on the seed germination and radicle growthin culture dishes were studied.The results showed that NaCl stress treatments below 200 mM concentration didn’t apparently influence the seed germination and radicle growth of cucumber.The seed germination and radicle growth of cucumber were significantly inhibited above 200 mM NaCl,and with increasing NaCl stress concentration,the germination rate,germination vigor,germination index,vigor index of cucumber seeds were drastically reduced,the length and fresh weight of radicle,the number of the first lateral root of cucumber seeds were significantly decreased.Of five cucumber varieties,the depressed degree of the seed germination and radicle growth of ‘Jinchun No.4’ and ‘Jinyou No.10’,especially ‘Jinchun No.4’ by NaCl treatments were larger,which of ‘Jinchun No.2’ and ‘Jinyou No.2’ were less,which of ‘Jinyuan No.3’ was between the above two types.
