Abstract
The effect of AlCl3 on endosperm reserve mobilization of rice grains or dehulled rice grains during germination was investigated. AlCl 3 had no effect on grain fresh and dry masses, protein and starch contents, and α-amylase and protease activities in endosperm of germinating rice grains. However, when dehulled rice grains were treated with AlCl3, AlCl3 inhibited the decrease in fresh mass, dry mass, and starch and protein contents, and the increase in α-amylase and protease activities in endosperm. Evidence is provided to show that the hull is a barrier against influx of Al to endosperm.
