图5 栽培密度对抽穗期玉米穗位叶和穗下第4叶荧光参数的影响 LD: 低密度; MD: 中密度; HD: 高密度。柱上不同字母表示不同处理差异在0.05水平显著。

Fig. 5 Effects of planting density on fluorescence parameters of ear leaf and the fourth leaf below ear of maize at heading period LD: low planting density; MD: medium planting density; HD: high planting density. Bars superscripted by different letters are significantly different at the 0.05 probability level among different treatments.
