图2 高温胁迫下及胁迫解除后5 d叶片碳水化合物输出能力的变化及其在品种间的差异 k1和k3分别表示高温胁迫下PHY370WR与苏棉15碳水化合物输出效率的下降斜率; k2和k4分别表示高温胁迫解除后PHY370WR与苏棉15碳水化合物输出效率的恢复斜率。

Fig. 2 Differences of carbohydrate transportation efficiency in leaves of different heat-tolerant cultivars under and after high temperature k1 and k3 represent the decline slopes of PHY370WR and Sumian 15 under heat stress, respectively; k2 and k4 represent the recovery slopes of PHY370WR and Sumian 15 after heat stress released, respectively.
