Characterization of rice (Oryza sativa) seedlings growth under different levels of submergence. a Photographs of 14 days-old rice seedlings after exposed different levels of submergence for 8 days. b The phenotypes of plant height after exposed different levels of submergence treatment for 8 days. (1st, 2nd and 3rd; length of the first, second and third leaf sheath). c Plant height of 14 days-old rice seedlings after treated submergence for 2, 4, 6 and 8 days. d The third leaves sheath length of 14 days-old rice seedlings after treated submergence for 2, 4, 6 and 8 days. Control check (CK), partial submergence (PS) and full submergence (FS). Bar = 3 cm. The data represent average values ± SD from 30 seedlings of each treatment obtained from six biologically independent experiments. Values with the different letters are significantly different at P < 0.05, according to post-hoc LSD test
