| Abstract (English): |
【Objective】To analyze the correlation of chlorophyll SPAD value and sugar content and root yield in root expansion stage and sugar accumulation stage, so as to provide theoretical reference for the promotion and planting of beet varieties.【Methods】The relative chlorophyll contents during yield at root expansion stage and sugar accumulation stage of sugar beet were tested by the SPAD-502 PLUS, and the sugar content and yield of beetroot were measured after ripening.【Results】The negative correlation between chlorophyll SPAD value and sugar content, Correlation coefficient -0.591.The correlation between chlorophyll SPAD value and yield per root, Correlation coefficient 0.279.The negative correlation between sugar content and and yield per root, Correlation coefficient -0.413.【Conclusion】High yield of root index is better than high sugar content index in sugar beet breeding and cultivation variety selection, and increasing the yield of root is the main way to increase the sugar yield of sugar beet, and chlorophyll SPAD value can be used as reference selection index.

目的 分析 58 个甜菜品种块根膨大期和糖分积累期的叶绿素 SPAD 值变化规律及其与含糖率及块根产量的相关性, 为甜菜品种的推广种植提供理论参考。方法 利用 SPAD-502 PLUS 便携式手持叶绿素仪, 测定甜菜膨大期和糖分积累期相对叶绿素含量, 并于成熟后, 测量甜菜含糖率和各小区甜菜块根产量, 计算产糖率。结果 甜菜叶绿素 SPAD 值与含糖率及块根产量具有不同程度相关性, 其中叶绿素 SPAD 值与含糖率存在负相关, 相关系数-0.591; 叶绿素 SPAD 值与产量存在相关, 相关系数 0.279; 含糖率与块根产量存在负相关, 相关系数-0.413。结论 在甜菜栽培品种选择上, 选择块根产量指标优于含糖率指标, 提高块根产量是提高甜菜产糖量的主要途径, 叶绿素 SPAD 值可作为参考选择指标。 [ABSTRACT FROM AUTHOR] |
