| 摘 要： | 2008年年初，曲靖市遭受了30年来同期最严重的冻害天气，各种植物均受到不同程度的冻害．重点分析了3种杜鹃花科植物在2006—2008年的物候期情况．经研究表明：2008年，3种植物的发芽始期、芽膨大期、展叶始期、展叶盛期、花蕾期、开花始期、开花盛期和开花末期均晚于2006年和2007年，虽然物候期推迟了，但都能正常完成生活史，说明这3种植物对低温具有一定的抗性，是比较优良的园林绿化植物．

| Abstract: | At the beginning of 2008, Qujing has suffered from the most serious freezing weather in the past 30 years and many kinds of the plants were badly injured. The phenological periods of three Ericaceae plants from 2006 to 2008 were analyzed and the results showed that, the initiation budding, budding swelling, initiation leafing, flushing leafing, bud flowering, initiation flowering, flushing flowering and ending flowering of most Ericaceae plants were delayed in 2008 compared with 2006 and 2007. However, all of these plants could fulfill their life history, which indicates that the 3 plants have certain resistance to low temperature and they can be chosen for landscaping plant. |
