Comparison of leaf sheath lengths in ‘TL3’ and ‘FR13A’ rice seedlings under submergence stress. a Photographs of 10-d-old upland and lowland rice seedlings after being exposed to air or submerged for 8 d. The distance from the 1st oldest leaf to the 2nd oldest leaf is leaf sheath distance I, and that from the 2nd oldest leaf to the 3rd oldest leaf is leaf sheath distance II. b and c Leaf sheath distances I and II of 10-d-old rice seedlings after submergence for 4, 6, 8, and 10 d. Air, non-submerged controls; Sub, full submergence; ‘TL3’, upland rice; and ‘FR13A’, lowland rice. Bar = 3 cm. Data points are means ± standard deviation of three separate experiments each with at least 30 seedlings of each genotype. Values with different letters are significantly different at P < 0.05, according to a post-hoc LSD test
