Abstract: The glume-opening of rice could be promoted by CO_2 gas or solution with aconcentrition higher than 5% or a pH lower than 5.6 mol/L with a solution of carbonateand dilute acid.The time needed for the induction of glume-opening by CO_2 was 20 se-conds.Further increase in CO_2 concentration or prolong
