    Abstract

    A research to identify the effect of submergence stress on the growth of rice plants was done at the green house and the field of Faculty of Agriculture, Sriwijaya University with factorial randomized block design. Seven genotypes of rice used were B 5244g-Sm (V1), B 7003d-Mr (V2), B 6996d-Mr (V3), B 5565d-13g-Sm (V4), IR 37664 (V5), Kapuas (V6), and Siputih (V7); and the submergence treatments were P0 (no submergence), P1 (one day submergence), P2 (three day submergence), P3 (five day submergence), and P4 (seven day submergence). The result showed that submergence affected the growth of rice at vegetative stage, and the rice genotypes tested had their specific response not only during the submergence treatment period, but also during their recovery phase after submergence treatment terminated. Rice genotype of B 5244g (V1) and B7003d (V2) showed better agronomic characteristics and have possibility to be used as new rice strain that have submergence tolerance at vegetative stage. Some plant characters that might have important effect to improve plant recovery ability after submergence are leaf chlorophyll content after submergence and low height addition during submergence. Key words: Rice, Submergence Stress, Vegetative Stage
