Abstract
The effects seed water content,freezing temperature and time on the seed germination of maize were studied.The results showed that the antifreezing ability of Zong 3 was the best,and that of 478 was the worst.With low temperature freezing,the germination was lower when the seed water content was higher than 19%,the freezing had little effect on germination within 12 hours,and influenced the germination below-5 ℃ over 24 hours,and the seed germination decreased with time prolonged and temperature drop.
