摘要：为了揭示常见道路绿化树种抗寒能力,运用相对电导率法测定新乡5种不同绿化树种的半致死温度,并进行分析。结果表明:女贞、广玉兰、海桐、大叶黄杨及小叶黄杨半致死温度分别为-5.316、-16.951、-18.755、-11.258、-7.511℃;海桐和广玉兰抗寒性较强,大叶黄杨抗寒性中等;小叶黄杨和女贞抗寒性相对较弱。
In order to reveal the cold-resistant capability of common read green trees, the semi-lethal temperatures （LT50） of 5 kinds of affor-estation tree foliage freezing injury in Xinxiang were measured and analyzed by relative conductivity method. The results showed that the semi-lethal temperatures of Ligustum iucidum, Maqnolia grandiflora, Pittosporum tobira, Buxus megistophylla and Buxus sinica were - 5. 316, - 16.951, - 18. 755, - 11. 258 and -7.511 ℃, respectively, the cold-resistant capability of Pittosporum tobira and Maqnolia grandi-flora was stronger, Buxus megistophyUa was in the intermediate level, and Buxus sinica and Ligustum iucidum was weaker.
