摘　　要：以正常茭、雄茭、灰茭3种茭白为材料,测定并比较三者的形态指标、叶绿素含量、光合气体交换指标。试验结果表明,自然条件下,雄茭与灰茭、正常茭在形态上有着显著差异,而灰茭与正常茭间差异不显著;正常茭白的叶绿素含量最高,灰茭次之,雄茭最小;正常茭具有最强的光合能力,灰茭次之,雄茭最弱。Morphological characteristics,chlorophyll content and photosynthetic gas exchange were determined in the Zizania latifolia plants,the plants infected by M-T strain or T-strain of Ustilago esculenta,respectively.The results showed that in outdoor conditions,morphological characteristics of uninfected Z.latifolia were significantly different from the other two types,but no significant difference existed between T-strain infected and M-Tstrain infected Z.latifolia.The chlorophyll content of M-Tstrain Z.latifolia was the highest,followed by T-strain infected and uninfected Z.latifolia.
