Morphometric parameters of carrot seed quality and factors determining them

Relevance. The contribution of varietal and environmental factors to the variability of the length of the endosperm and the embryo of carrot seeds was studied. Materials and methods. The objects of study were the original seeds of Rogneda, Lubava and Chernozemochka, Chantene 2461 and Boyarynya varieties. The seeds were grown at the Voronezh and West Siberian experimental stations. The linear dimensions of the seed and endosperm were measured using a caliper. The length of the embryo was measured using a microscope (Micromed) and a video eyepiece (DCM 300 MD) at х40 magnification. Statistical processing of the research data two-factor experiment was carried out using analysis of variance. Differences in the compared parameters were considered statistically significant at p 0.05. Results. The linear dimensions of all the main elements of seeds, as well as the index of le/z on average for three years significantly differed in the studied carrot varieties (P
