Abstract:: Taking 35 varieties of melon seed as materials,using petri dishes sprouting method,the effect of different concentrations of NaCl solution on germination rate,germination potential, germination index,the number of lateral roots were studied.The results showed that,NaCl stress on seed germination capacity with different degrees of inhibition,inhibition with increasing salt concentration strengthened;50 mmol/L NaCl solution stress could promote seed growth;germination rate,germination potential,germination index three indicators could be integrated together as a melon seed salt tolerance approach,‘Sugar Jar 2’ was the most salt-tolerant variety,‘7 inbred lines’was the least tolerant variety.
