Stagnant water/ waterlogging
Rice is affected
either by flash or stagnant flooding. A complete inundation for a short
duration (usually 1-3 weeks) occurs in flash flooding whereas 20-50 cm water
stagnates for up to a few months in case of stagnant flooding.
The SUB1 gene is effective only under flash
flood conditions. Stagnant flooding reduces yield through suppressing
tillering; leaf area development; panicle size, fertility, and survival.
