| Abstract:
The effects of temperature, water stress and plant bioregulators on the sexual differentiation of cv. Irwin mango flowers were investigated in a warm climate area of Japan. The proportion of perfect flowers was little different between the plants grown at 20C and 30C. Water stress caused by irrigation at two week intervals slightly lowered the proportion of perfect flowers. Sex ratio was affected by plant bioregulators GA350ppm appied to the undifferentiated panicles decreased the number of perfect flowers. On the other hand, application of BA 1000ppm when floral organs had differentiated in the panicle increased the number of perfect flowers. These results suggest that gibberellins and cytokinins are involved in the sexual differentiation of mango. | |
