摘要:: 以“陕林4号”和“07-69×青1”为试材，分别用浓度为0、5、10、15、20 mmol/L的CaCl₂溶液喷施杨树幼苗，4℃低温胁迫2 d后测定杨树幼苗的膜伤害率、丙二醛(MDA）含量、抗氧化酶(SOD和POD）活性以及可溶性蛋白质含量等生理指标，以探究低温胁迫下不同浓度外源Ca²⁺对杨树幼苗抗寒相关生理指标的影响。结果表明：在喷施10 mmol/L CaCl₂的作用下，杨树幼苗的各项抗寒相关生理指标最优，可显著降低杨树幼苗的膜伤害率，减少丙二醛(MDA）含量，提高超氧化物歧化酶(SOD）活性和过氧化物酶(POD）活性，增加可溶性蛋白质含量。外源Ca²⁺可以有效提高杨树幼苗的抗寒能力，缓解低温胁迫对杨树幼苗的伤害。

Abstract:: The young seedlings of ‘Shaanlin No4’ and‘07-69×P.cathayana 1’ were used as experiment materials.In this research，CaCl₂ concentrations of 0，5，10，15，20 mmol/L were sprayed before treated under 4℃ stress for 2 days.Then，physiological indexes including membrane injury rate，activities of antioxidant enzymes (SOD and POD)，contents of MDA and soluble protein were measured to investigate the effect of different Ca²⁺concentration on cold tolerance related physiological indexes in poplar under low temperature stress.The results showed that membrane injury rate and MDA content were decreased under 10 mmol/L CaCl₂ treatment，while antioxidant enzymes (SOD and POD) and soluble protein were increased significantly.In conclusion，it was made sense that exogenous Ca²⁺could effectively improve the cold tolerance of poplar seedlings and alleviate the damage caused by low temperature stress.
