图5 高温胁迫5 d及恢复5 d时棉铃对位叶蔗糖、淀粉含量日变化幅度与碳水化合物输出效率的相关性 用同位素13C标记结果计算所得的碳水化合物输出效率与叶片中淀粉含量和蔗糖含量的日最大变化幅度进行相关性分析, 对应色块的颜色越深表明相关性越强。**表示1%显著水平。

Fig. 5 Correlation between diurnal variation of sucrose and starch content and carbohydrate transportation efficiency in cotton leaves after five days of high temperature stress and five days of recovery The darker the color of the block, the stronger the correlation between carbohydrate transportation efficiency and the diurnal conversion rates of starch content and sucrose content in subtending leaves. ** Significant at the 1% probability level.
