统计结果表明,水稻各叶位气孔数量组成的变化主要是由本身特性所决定的.环境条件有一定的影响,但各生态因素的影响途径和结果有所不同.水、温主要是影响伸长的叶位.干旱抑制细胞伸长,使叶面积减小而提高气孔密度,降低气孔长度,达极显著水平.在水稻生长温度范围内,提高温度的结果则相反,但不显著.弱光主要影响叶原基阶段气孔的分化形成,且使气孔密度和长度相应发生变化. The statistical results showed that the changes of the stomatal numbers in different leaf positions of rice were mainly determined by their own characteristics, the environmental conditions had a certain impact, but the ways and results of different ecological factors were different. Water and temperature mainly affected the elongation Of the leaf position.Drought inhibition of cell elongation, the leaf area decreased and increased stomatal density, decreased stomatal length, reaching an extremely significant level in the rice growth temperature range, the results increase the temperature is the opposite, but not significant. Which affects the formation of stomata at leaf primordial stage and changes the stoma density and length correspondingly.
