| Abstract: | Certain embryological and biochemical effects of the cytokinin (SD 8339) in converting flower sex from male to hermaphrodite were studied in a clone of Vitis vinifera L. (sylvestris). The cytokinin accelerated the meiotic division of the megaspore mother cell, mitotic divisions of the megaspore and cells of pistillate tissue, and increased the rate of protein synthesis in flower buds. Two working hypotheses for the possible mode of action of the cytokinin in sex conversion are presented. |
