This paper shows the results of studying the varieties of blackberry 'Darrow', 'Thornfree', 'Smoothstem' to obtain organic production in the climatic conditions of the Republic of Moldova. The research was based on monitoring the phenological, organoleptic, and biometric indicators in 2011, 2013 and 2014. The use of varieties with increased resistance to environmental conditions, pests and diseases is one of the essential ingredients, originated from the organic farming. During the years 2013-2014 in all varieties studied was not observed frostbites on blackberry plants, no symptoms of disease and pest attack. Biochemical composition of fruits was determined to remark the nutritional qualities and taste of organic blackberry fruit. In assessing the coefficient sugar / acidity, best manifested variety was 'Thornfree' by the average amount of 2.87, followed by 'Smoothstem' variety - 2.76. After the dry matter content, stands out the Smoothstem variety, by the average amount of 12.02% for the period studied, but by the content of vitamin C is predominant the variety 'Darrow' with thorns by the average amount of 26.13 mg%. Regarding the level of productivity, the highest yields in 2014 were obtained from varieties without thorns, especially the variety 'Thornfree' with a value of 7.64 kg in a bush.

The paper presents the results of studying the varieties of blackberry 'Darrow', 'Thornfree', 'Smoothstem'. According to research conducted in assessing biochemical composition of fruits in the Republic of Moldova, to determine the content of dry matter, sugars, acidity, vitamin C, tannins and coloring substances in blackberry fruit for the years 2010-2011 and 2013. Of the varieties mentioned, on can noted 'Smoothstem' variety with a rich medium dry matter (12.67%) and a high coefficient of sugar / acidity (3.18). The variety 'Darrow' recorded the lowest average results of these indicators (10.67% 2.57%), but higher average values manifested by the content of vitamin C and tannins and coloring substances, reaching respective values of 26.05 mg% and 48.50 mg%.

This article presents the results obtained in a study of sea buckthorn varieties introduced in Republic of Moldova during the years: 2005; 2010; 2013. The plantation was established in 1999 by using a planting distance of 3.0 to 2.0 m and studied varieties: 'Nivelina', 'Botaniceskaya', 'Podaroc sadu', 'Trofimovskaya' and 'Otradnaya'. Our research allowed us to set the limit of variation for the values of accumulated nutrients in fruits, using the following indices: dry weight from 7.87 to 10.07%, the amount of sugar accumulated between 2.14 to 8.18%, between 1.5-4.5% titratable acidity, tannins and coloring substances from 29.10 to 83.14 mg% and the sugar / acidity coefficient from 1.15 to 4.81.
