Показана динамика развития научных основ селекции овощных культур за период дея тельности Грибовской селекционной станции - ВНИИССОК (1920-2010 годы).

The International Conference of Young Scientists «Advances in Botany and Ecology» was held in September 19-23, 2012,Uzhgorod, Ukraine. The meeting was devoted to achievements of botany, physiology, mycology, bryology and lichenology, plant physiology and biochemistry, systematic of vascular plants, plant ecology and phytosociology. The organizers of the conference are M.G. Kholodny Institute of Botany of National Academy of Sciences of Ukraine and Uzhgorod National University/

This review gives facts concerning the ecological situation in the world. The ways how to organize the enhanced consumption of ecologically safe food were shown.

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 Ie/z on average for three years significantly differed in the studied carrot varieties (P < 0.001). The maximum length of the seed (3.14±0.02 mm), the length of the endosperm (2.66±0.02 mm) and the length of the embryo (1.23±0.03 mm) on average for three years was observed in the Rogneda variety. The average coefficient of variation (V) of seed length was minimal and varied from 10.1% to 12.9%. The average values of the coefficient of variation (V) for the length of the endosperm varied in a wider range from 12.0% to 14.6%. The length of the embryo had a maximum level of variability from 18.7% in the Rogneda variety to 20.3% in the Chernozemochka variety 21.3%. The variety factor had a predominant influence (from 50.8 % to 86.5 %) on the size of the seed and its morphological elements. The contribution of the environmental conditions of the year of reproduction to the formation of morphometric parameters did not exceed 22.3 %. This allowed us to draw a conclusion about the prospects of selection and the possibility of selective changes in the morphological parameters of the seed.
