| 摘 要： | 以蒙古柞、尖柞和槲柞树品种为材料,对解除柞树休眠所需的低温时数进行了试验研究。结果发现:解除柞树休眠与需冷量有关,低温时数对不同柞树品种的影响不同;柞树接触低温时间过长,其发芽开叶所需时间相对增长;柞树休眠后接触4~5℃低温时数达360h,蒙古柞、槲柞和尖柞树可有效提早解除休眠。

| Abstract: | With Quercus mongolica Fisch.,Quercus mongolica dentata and Quercus acutissima Carruth as materials,the chilling period needed for breaking dormancy of oak trees was discussed in this paper.The result of experiment showed that dormancy release of oak trees is connected with chilling requirement;and the effect of chilling period varies among different oak varieties.The more chilling period the oak trees accept,the longer time needed for their budding and leaves blossom.If the dormant oak trees were given 4℃ to 5℃ temperature up to 360h,the dormancy of Quercus mongolica Fisch.,Quercus acutissima Carruth and Quercus mongolica dentata would be broken in advance. |
