摘要：
Changes in acid and alkaline phosphatase activities in cytoplasmic and wall-bound fractions of developing mustard (Brassica juncea) seed were studied. Growth was measured by seed dry weight and water content. Seed dry weight data were fitted to a cubic polynomial equation. Seed water content and dry matter accumulation was significantly correlated. Cytoplasmic acid and alkaline phosphatase activities were substantially less in the cytoplasmic fraction than the wall-bound fraction. Wall-bound acid phosphatase activity was low initially, but high levels were maintained after day 25, indicating a relationship with dry matter accumulation. The results suggest that acid phosphatase plays an important role during mustard seed development.
