WebbFor citrus, there is no definition of the ideal fruit harvesting point for seed extraction. Some studies have shown the positive effect of postharvest refrigerated storage of fruits to obtain quality seeds.

Primary dormancy occurs while the seed is maturing on the mother plant or shortly thereafter. Primary dormancy, due to increased levels of abscisic acid (ABA), prevents seed germination in the pod known as precocious germination or vivipary.
WebbDormancy is a form of developmental arrest and is an adaptive trait that promotes the survival of many organisms. In flowering plants, dormancy occurs in seeds and vegetative propagules (Lang 1996). Seed dormancy increases the dis-tribution of germination over time, thus enhancing the sur-vival of plants in an ever-changing environment. Seed dor- http://psasir.upm.edu.my/id/eprint/99376/

ABA is a plant hormone that regulates many aspects of plant growth and development, including seed dormancy and germination. ABA levels increase in seeds as they mature, and high levels of ABA in seeds can induce dormancy by inhibiting germination. track near me runningWebbdormant seed.
