Histochemical techniques were used to study aleurone grains in developing cotyledons of four cultivars of Phaseolus vulgaris L. The ninhydrin-Schiff’s reaction and the 2,2’-dihydroxy -6,6’ dinaphthyl-disulfide (DDD) method were used to identify total protein and proteinbound sulfhydryl and disulfide groups respectively. Aleurone grains of the subepidermal and adjacent mesophyll cells showed a more intense staining reaction to DDD 28 days after flower opening than the rest of the cotyledon, and… CONTINUE READING
