‘ｐｏｐｕｌａｒｉｓ３５－４４’）１年生插条苗进行盆栽试验，发现它们对空气和土壤干旱的耐性存在很大差异，其中Ｂｅｒｏｌｉｎｅｎｓｉｓ对空气干旱的耐性最强，对土壤水湿的耐性最弱；Ｉｔａｌｉｃａ和Ｒｏｂｕｓｔａ对土壤干旱反应敏感，当田间持水量（ＦＦＣ）降至４０％时，净光合速率（Ｐｎ）已显著降低，严重干旱（３０％ＦＦＣ）时，苗木下部１／４叶片脱落，同时，上部叶面积生长受到很大抑制；Ｂｅｒｏｌｉｎｅｎｓｉｓ和Ｐｏｐｕｌａｒｉｓ虽在干旱初期Ｐｎ下降显著，但７ｄ后Ｐｎ不同程度回升，并且受旱期间叶面积生长受到的影响较小，即显示出对土壤干旱的耐性，因此，杨树无性系对土壤干旱耐性依次为Ｐｏｐｕｌａｒｉｓ＞Ｂｅｒｏｉｉｎｅｎｓｉｓ＞Ｒｏｂｕｓｔａ＞Ｉｔａｌｉｃａ。
