Abstract
We report a study on the growth and development of morphologically underdeveloped embryos in dill seeds, and their impact on germination. The influence of dill umbrella location on embryo growth and seed germination under standard conditions is investigated. In the process of germination in dynamics, the length of the embryo from umbrellas located on the shoots of the first and second orders of branching is measured. Parameters of the model of embryo growth and germination of dill seeds are calculated. The different quality of the initial length of the embryo (p < 0.001), a significant difference in the length of the embryo in full germination (p < 0.001), and growth time of 50% of the length of the embryo, necessary for germination (p = 0.009), are revealed. It is found that at the beginning of germination, embryos in seeds from different branching orders are at different stages of development. Studies show that under standard controlled germination conditions the germination rate and seed germination percentage depend on the stage of the embryo development.
