Abstract
The influence of the location of the umbel of dill (Centaurus variety) (Anethum graveolens L.) on the linear parameters of the seed was investigated. It was revealed that the average values of the dill seed length (3.85–3.43 mm), endosperm (3.37–2.99 mm) and the embryo (1.00–0.77 mm) varied significantly. Quality differences in the parameters of the morphological elements of the seed depended on both the architectonics of the seed plant and environmental conditions. The endosperm length averaged 88–89% of the seed length. The length of the embryo in the primary inflorescences was 26% of the length of the seed and 30% of the length of the endosperm; in secondary umbel - by 5 and 6% lower. The length of the seed and endosperm was mainly influenced by the environmental factor (P <0.001), and the length of the embryo by the matric factor (P <0.001). Correlation analysis showed that the effect of seed length on the length of the endosperm had a high positive dependence (r = 0.961 - 0.978). There is a weak correlation between the length of the embryo and the length of the seed, as well as between the length of the embryo and the length of the endosperm (r = 0.050–0.314 and 0.066–0.325, respectively).
