DENDROLOGY

Detailed explanation-1: -However, even rice plants can suffer yield loss or die if the water is too deep for a long time. In response to waterlogging, rice and many wetland plants form gas spaces called “aerenchyma” by inducing the death of cells inside the roots, allowing oxygen to be transported from leaves down to the roots.

Detailed explanation-2: -Rice crop requires more amount of water during irrigation as water and soil sediments assist rice plants in controlling the optimum temperature and maintain humidity in the surrounding area. Thus, the required supply of water is very essential for the survival of paddy crops.

Detailed explanation-3: -Strategies of adaptation to excess water stresses in the form of submergence or waterlogging in rice plants. Rice can adapt to submergence by internal aeration and growth control. For internal aeration, rice develops longitudinally forming aerenchyma and leaf gas films.
