[目的]为巴黎的栽培、育种及植物传粉生物学研究提供基础资料。[方法]观察巴黎属6种植物的花药开合现象，测定花药附近的温度、湿度和光照。[结果]巴黎重楼、巴黎重楼、巴黎滇重楼（Paris polyphylla var.yunnanensis（Franch）Hand.-结果表明，滇重楼和高邦重楼的花药开放和关闭时间比酒泉重楼、大理重楼、云南重楼和多叶重楼早1h左右，滇重楼、高邦重楼、大理杨和云南杨较长，玉泉杨和云南杨较短;巴黎属植物的花粉开放和闭合过程与一天内光照和温度的变化呈正相关，与空气相对湿度呈负相关。[结论]巴黎属植物的花药沿着气温的升高和相对湿度的降低而逐渐开放，巴黎花药开放和闭合的持续时间与花药大小有关。
[Objective] The study aimed to supply basic data for the cultivation,breeding and research on plant pollination biology of Paris.[Method] The anther opening and closing phenomena of 6 species of Paris genus were observed and the temperature,humidity and illumination near the anther were determined.[Result] The anther openings of Paris iuquanensis H.Li,Paris daliensis H.Li et V.G.Soukoup,Paris polyphylla var.yunnanensis(Franch) Hand.-Mazz and Paris polyphylla Smith in Rees were relatively earlier and that of Paris dunniana Levl and Paris caobangensis Y.H.Ji,H.Li Z.K.Zhou were relatively later.The anther closings of P.dunniana and P.caobangensis were about 1 h earlier than that of P.iuquanensis,P.daliensis,P.polyphylla var.yunnanensis and P.polyphylla.The durations of anther opening and closing of P.dunniana,P.caobangensis,P.daliensis and P.polyphylla var.yunnanensis were longer and that of P.iuquanensis and P.polyphylla were shorter.The anther opening and closing course of paris genus showed positive correlation with the variation of illumination and temperature in a day and negative correlation with relative air humidity.[Conclusion] The anthers of paris genus opened gradually along with the ascending of air temperature and the descending of relative air humidity.The durations of paris anther opening and closing related to the size of anther.
