VARIABILITY AND RELATIONSHIP OF MORPHOLOGICAL ELEMENTS OF SEEDS OF DILL (ANETHUM GRAVEOLENS L.) UNDER INFLUENCE OF EXTERNAL AND INTERNAL FACTORS
An investigation was made on the effect of the location of the centrifuge dander of the Centaur variety ( Anethum graveolens L.) on the linear parameters of the seed. The seeds were sown on the experimental field of the FGBNU VNIIO in 2015-2016 years and grown to produce seeds. 30 plants were selected in threefold repetition for each variant at random, and umbrellas were cut in accordance with the experimental design. Then, the length and width of the seed, embryo and endosperm from umbrellas , located on shoots of first, second order of branching and control were measured. It was found, that the mean lengths of the elements of the seed (3.85 - 3.43 mm), endosperm (3.37 - 2.99 mm) and embryo (1.00 - 0.77 mm) of dill varied considerably and depended on architectonics of a seed plant and environmental conditions. The length of the endosperm averaged 88-89% of the length of the seed. The length of the embryo in the inflorescences of the first order was 26% of the length of the seed and 30% of the length of the endosperm, and in umbrellas of the second order - 5 and 6% lower. The length of the seed and endosperm was mainly influenced by growing conditions (77% and 81%, respectively), and the length of the embryo - the maternal factor (92%). Correlation analysis showed that the influence of the length of the seed on the length of the endosperm had a high positive dependence (r = 0.961-0.978). Between the length of the embryo and the length of the seed; Also the length of the embryo and the length of the endosperm, a weak linkage was noted (r = 0.050-0.314 and 0.066-0.325 respectively).
