研究了秋末迎春5号杨叶片激素含量的变化，并进行了温度相关性分析，发现随着气温的下降，ZR含量、ABA含量、IAA含量以及ABA／GA比值、IAA／GA比值呈上升变化，与温度的相关系数分别为－0．667、－0．907、－0．569、－0．871和－0．938；而GA含量为下降趋势，与温度的相关系数为0．774。ABA含量和IAA／GA比值与温度达到极显著负相关，ABA／GA比值到显著负相关，GA含量到显著正相关，表明这些指标可能与杨树抵御低温密切相关。
研究瞭鞦末迎春5號楊葉片激素含量的變化，併進行瞭溫度相關性分析，髮現隨著氣溫的下降，ZR含量、ABA含量、IAA含量以及ABA／GA比值、IAA／GA比值呈上升變化，與溫度的相關繫數分彆為－0．667、－0．907、－0．569、－0．871和－0．938；而GA含量為下降趨勢，與溫度的相關繫數為0．774。ABA含量和IAA／GA比值與溫度達到極顯著負相關，ABA／GA比值到顯著負相關，GA含量到顯著正相關，錶明這些指標可能與楊樹牴禦低溫密切相關。
연구료추말영춘5호양협편격소함량적변화，병진행료온도상관성분석，발현수착기온적하강，ZR함량、ABA함량、IAA함량이급ABA／GA비치、IAA／GA비치정상승변화，여온도적상관계수분별위－0．667、－0．907、－0．569、－0．871화－0．938；이GA함량위하강추세，여온도적상관계수위0．774。ABA함량화IAA／GA비치여온도체도겁현저부상관，ABA／GA비치도현저부상관，GA함량도현저정상관，표명저사지표가능여양수저어저온밀절상관。
Experiments were carried out to study the changes of hormone content of Populus בZhonglin Sanbei 1’ and the correlation with temperature .The result showed that the contents of ZR ,ABA ,IAA ,ABA/GA and IAA/GA were on the increase with the temperature declining .The correlation coefficients of various hormones and tem‐perature were -0 .667 ,-0 .907 ,-0 .569 ,-0 .871 ,-0 .938 respectively .The content of GA was declining and the e correlation coefficient was 0 .774 .The content of ABA and IAA/GA ratio reached extremely significant negative correlation with temperature .The ABA/GA ratio was significant negative correlation with temperature ,the content of GA was significant positive correlation with temperature .The data suggested that these indicators may be closely related with poplar resist low temperature .
