| 中文摘要: |
| 利用叶绿素荧光技术研究了59 个甘蔗细茎野生种质资源的叶片叶绿素荧光特性，为高光效甘
蔗细茎野生资源的筛选利用及高光效甘蔗品种改良提供参考。结果表明：光合特性4 个参数Fv/Fm×ETR
factor/2 最大电子传递产量、α 光合利用效率、ETRm 最大电子传递速率、Ik 最小饱和光强差异均达到达到
极显著。采用系统聚类分析方法，以α 光合利用效率为指标，将59 个材料分为4 大类，即Ⅰ类高光合利用
效率、Ⅱ类中高光合利用效率、Ⅲ类中光合利用效率和Ⅳ类低光合利用效率。筛选出云南75- Ⅰ-10、云南
82-61、福建登科8 号和四川88-34 等4 个高光效种质材料，在甘蔗原始创新上可加以利用。 |

| Chlorophyll fluorescence technology was applied to investigate the chlorophyll fluorescence
characteristics of 59 sugarcane germplasm resources，to provide a reference for the high photosynthetic efficiency of
sugarcane resources utilization and screening of high photosynthetic efficiency of sugarcane variety improvement.The
results showed that，the photosynthetic characteristics differences of the 4 parameters Fv/Fm * ETR factor/2，alpha
ETRm maximum light use efficiency，electron transfer efficiency，Ik minimum saturation intensity differences were
significant. Using cluster analysis method，α photosynthetic light use efficiency as the index，the 59 materials were
divided into 4 categories，namely class Ⅰ high photosynthetic efficiency，class Ⅱ in high photosynthetic efficiency
and photosynthetic efficiency in class Ⅲ and Ⅳ low photosynthetic efficiency. Four high efficiency germplasm
materials were selected，including Yunnan 75- I -10，Yunnan 82-61，No. 8 of Fujian dengke，and Sichuan 88-34，which could be used on the original innovation in sugarcane. |
