作者就自然低温条件对玉米幼苗根尖分生组织的影响及其恢复状况,对变换低温处理期间进行了调查。并就静止中心在根尖分生组织恢复中所起的作用进行了探讨。试验把种根长15～20毫米的玉米幼苗在生育室进行水培。室内气温昼夜为20℃/15℃,
The authors investigated the effect of natural low temperature on the apical meristem of maize seedlings and their recovery status, and investigated the changes during low temperature treatment. The role of rest center in the recovery of apical meristem was also discussed. Test the seedling root length 15 to 20 mm corn seedlings in the reproductive room for hydroponics. Indoor temperature day and night is 20 ℃ / 15 ℃,
