Thus, this study aimed to determine physiological and enzymatic changes during the maturation process of melon seeds of the cultivar BRS Anton, obtained from fruits at different maturation stages and subjected to post-harvest storage, by the action of total proteins and the enzymes catalase, peroxidase, and superoxide dismutase. Melon fruits were grown in a greenhouse at Embrapa Vegetables and harvested at five different times: 30, 45, 60, 75, and 90 days after anthesis (DAA). |

Conteúdo: |
Male meiosis is generally synchronous in higher plants. The regulation of the cell cycle is still not well understood, and a powerful tool for gaining an understanding of this regulation is the development of mutations that affect cell-cycle synchrony. We report here asynchronous microsporogenesis in an interspecific hybrid between two important tropical grasses. In young spikelets of the interspecific hybrid 49.10% of anther meiocytes entered meiosis, exhibiting typical phases of the first and second divisions, while the other 50.90% showed distinctive features of early prophase. In older spikelets, anthers containing mature pollen grains also displayed meiocytes still undergoing meiosis. At this time, the latter cells were enclosed by the exine wall. Despite asynchrony, all cells completed meiosis. Old anthers contained only pollen grains that appeared to be in the same stage of development. Pollen fertility was estimated to be 52.76% in dehiscent anthers. An independent genetic control for meiosis synchrony and meiotic stages is suggested. |
