虽然谷子各品种间叶绿素SPAD无显著差异（表3.4），但叶面积具有显著

Although no significant differences (Table 3.4) the SPAD chlorophyll millet varieties, but significant differences in leaf area having to Zhang heteroaryl maximum leaf area No. 5, No. 6 Zhang heteroaryl minimum leaf area. In the same environment, heteroaryl sheets 5 can intercept light in the ability of other species, photosynthesis higher than other crops. Millet jointing sheets No. 5 hybrid optimal agronomic traits.

Although there was no significant difference between the varieties of chlorophyll SPAD (Table 3.4), there was a significant difference in leaf area, with the largest area of the 5th leaf and the smallest leaf area of the no. 6. In the same environment, Zhang hen 5 can intercept the light energy is more powerful than other varieties, its photosynthesis is also higher than other crops. The best performance of the agronomic traits of Zhang hen no. 5 during the grain pull festival was excellent.

Although there was no significant difference in chlorophyll SPAD among varieties of Millet (table 3.4), there was significant difference in leaf area, among which zhangza 5 had the largest leaf area and zhangza 6 the smallest. Under the same environment, the ability of light energy interception of zhangza 5 is stronger than other varieties, and its photosynthesis is also higher than other crops. Zhangza No. 5 showed the best agronomic characters at jointing stage.<br>
