| Abstract | This paper explores the morphological and physiological changes in Saluyot seeds as they reach physiological maturity. The experiment encompassed the period from anthesis to physiological maturity, with observations conducted at three-day intervals. Monitored parameters included seed pod and seed color, size, seed moisture content, seed dry weight, and seed germination rate. The results indicate a gradual increase in seed size from 21 days after anthesis (AA) to 39 days AA, followed by a decline at 42 days AA, with average seed sizes ranging from 1.18 mm to 1.46 mm and 1.42 mm, respectively. Additionally, the color of the seeds and their pods gradually changes from green to the formation of black spots, signifying chlorophyll degradation. The moisture content (MC) of the seeds also decreases progressively from 9 days to 24 days AA, with a rapid loss recorded from 27 days to 42 days AA, averaging between 86.78% and 78.21%, and 40.54% to 16.64%, respectively. Regarding seed dry weight, the maximum weight was observed between 39- and 42-days AA, at 0.71 mg and 0.70 mg, respectively, indicating the physiological maturity of seeds within this period. Moreover, Saluyot seeds displayed a low germination rate, with a maximum of 40% observed on 39 days AA. This low germination rate suggests the onset of dormancy in Saluyot seeds post-harvest. In summary, the physiological maturity of seeds, as indicated by maximum seed dry weight and germination rate, occurs at 39 days AA. |
