图3. 冷水淹没深度对水稻低温耐受性的影响
红色箭头指示茎尖生长点的位置, 该部位在处理I、II和III中分别处于水深的不同位置(虚线为水面)。图中百分数表示恢复生长7天后幼苗的存活率。以28°C水浴作为对照(左图)。Bars=6 cm
Figure 3. Effect of submerged depth of cold water on low temperature tolerance of rice
Red arrow indicated the site of shoot apical meristem under different water depth in chilling treatment I, II and III. Dotted lines represent the water surface. The survival rates were indicated on the top of the seedlings recoveried for 7 days. Treatment with 28oC water was used as control (left). Bars=6 cm
