Gas Exchange and NutritionThe limited diffusion of gases in water and the long, partly submerged herbaceous stems of deepwater rice with the normal cuticle layer of terrestrial plants obviously pose difficulties for the aeration of the plant. Part of the adaptation of floating rice to deeply flooded conditions lies in its ability to transport O. to the submerged organs.

Plant Population Dynamics and YieldThis aspect is given prominence because of its obvious relevance to eventual yield. Despite the fundamental importance of the seasonal dynamics of stand density, surprisingly few studies are available for broadcast rice, and none were known for deepwater rice until field studies started in Bangladesh in 1977.
