| 摘 要： | 利用调制式叶绿素荧光仪研究甘蔗苗期水分胁迫下叶绿素荧光参数的动态变化与甘蔗抗旱性的关系。结果表明，水分胁迫下Fv/Fm、Fv/Fo、Yield、Rfd等荧光参数随水分胁迫强度增强而下降，变化幅度因品种抗旱性强弱而异。水分胁迫下上述荧光参数的动态变化可作为简便易行的抗旱性强弱诊断指标在甘蔗抗旱育种上应用。

| Abstract: | The relationship of drought tolerance and chlorophyll fluorescence characters during water stress in seedling of sugarcane was stuided by using modulated chlorophyll fluorometer. The results indicated that Fv/Fm, Fv/Fo, Yield, Rfd values decreased gradually under water stress. With water stress intensifying, Fv/Fm, Fv/Fo, Yield, Rfd value were decreased depending on the genotypes. The decrease of these chlorophyll fluorescence parameters was closely related to drought tolerance of sugarcane varieties. The possibility of determining the drought resistance in sugarcane using chlorophyll fluorescence characters was studied. |
