Buletinul AŞM. Ştiinţele vieţii. Nr. 2(317) 2012 Abstracts +64.3 and +110.5%. The most performing late-ripening hybrid is Fr. 8-5-34V, with the highest indices of heterosis that has the highest content of essential oil – 5.098% (dry matter) 10 references, 3 tables, 3 fi gures. Keywords: Lavandula angustifolia - hybrid – heterosis - essential oil. Received May 08, 2012 UDC: 635.64:631.524.85 (478) MUTANT TOMATO FORMS AS A SOURCE OF ECONOMICALLY VALUABLE TRAITS FOR BREEDING. Makovei M.D., Ganea A. I. // Buletinul Academiei de Ştiinţe a Moldovei. Ştiinţele vieţii. 2012, No 2 (317), p. 91-100. This paper presents the most important morphological/biological and economically valuable features of collectible tomato mutant forms in relation to the breeding objectives. The genetic diversity of the mutant forms concentrated in the collection of the Center of Plant Genetic Resources has been shown. Forms with a stable manifestation of the traits studied, that may be included in breeding programs for their further use in the development of tomato varieties and hybrids have been identifi ed. 13 references, 2 tables. Keywords: Mutant tomato forms - morphological and biological characteristics - variability - plant growth type - growing season length - fruit color - fruit shape - fruit weight - pericarp thickness - seed chamber number. Received March 30, 2012 UDC: 639.21/.31.09:502.5(204)(478) THE STRUCTURE AND DYNAMICS OF ASIATIC CYPRINID POPULATIONS IN THE INTENSIVE EUTROPHICATION CONDITIONS OF THE REPUBLIC OF MOLDOVA AQUATIC ECOSYSTEMS. Bulat Dumitru, Bulat Denis, Toderaş Ion, Usatîi Marin, Toderaş Lidia, Fulga Nina, Şaptefraţi Nicolae. // Buletinul Academiei de Ştiinţe a Moldovei . Ştiinţele vieţii. 2012, No 2 (317), p. 100-117. This article analyses the situation of allogenic species of Asiatic origin (silver carp, grass carp, bighead carp) in the conditions of the Republic of Moldova beginning from their introduction in 1961 and to the present. It has been demonstrated that their effect is not invasive, the share being well controlled through fi sh population and extraction intensity. The abundance of these species has drastically increased in the natural aquatic ecosystems as a result of powerful fl oods that occurred in 2008 and 2010. In the condition of their possible naturalization, Asiatic cyprinids could become potentially invasive due to the accentuated competitive effect and unexpressed trophical selectivity. In addition, these species are basic objects of national fi shing and important biological ameliorators that may control the active eutrophication phenomenon of aquatic ecosystems. 45 references, 8 tables, 6 fi gures. Keywords: allogenic species - invasive effect - Asiatic cyprinid populations – eutrophication - biological ameliorator - aquatic ecosystems. Received 28 May, 2012 UDC: 573.6.086+615.9 ASSESSMENT OF THE TOXICITY <strong>DE</strong>GREE OF THE NANOPARTICLES CdSe, ZnSe AND ZnS ON THE MICROALGAE PORPHYRIDIUM CRUENTUM. Rudic V., Cepoi L., Rudi L., Miscu V., Chiriac T., Cojocari A., Sadovnic D., Guţul T., Todosiciuc A. // Buletinul Academiei de Ştiinţe a Moldovei. Ştiinţele vieţii. 2012, No 2 (317), p. 118-125. It was studied and established the toxicity of the luminescent nanoparticles on the Porphyridium cruentum culture that decreases in the sequence ZnSe>ZnS>CdSe. It was determinated the infl uence of these nanoparticles on the microalgae´s productivity that has an wave character 196

The specifi c method of the determination of the lipid peroxidation products permited the setting of the nanoparticles degree of toxicity. 13 references, 9 fi g Key words: Porphyridium cruentum – nanoparticles – toxicity - lipid peroxidation. Received March 27, 2012 UDC 579.083.13+579.24 BIOSYNTHESIS OF CARBOHYDRATES IN SACCHAROMYCES CEREVISIAE YEAST IN RELATION TO THE MEDIUM COMPONENTS. Chiseliţa Oleg, Usatîi Agafi a, Chiseliţa Natalia, Borisova Tamara. // Buletinul Academiei de Ştiinţe a Moldovei. Ştiinţele vieţii. 2012, No 2 (317), p. 126-134. The article presents the results of the impact of different carbon sources (glucose, saccharose, fructose, mannose, molasses), sulfate, acetate, and four coordinative zinc compounds on carbohydrate biosynthesis in the Saccharomyces cerevisiae yeast. A new culture medium is proposed, which increases the carbohydrate content in yeast biomass by 44.3%. 20 references, 2 tables, 3 fi gures. Key words: carbohydrates – yeast - Saccharomyces cerevisiae - carbon sources – acetate - coordinative zinc compounds. Received March 05, 2012 UDC: 579.61:616+616.992-078 RAPID INDICATION OF FUNGI OF THE CANDIDA GENUS IN ORAL CAVI- TY PATHOLOGY. Balan Greta, Puşcaş N., Melnic Iu. // Buletinul Academiei de Ştiinţe a Moldovei. Ştiinţele vieţii. 2012, No 2 (317), p.135-141. A nutrient medium has been developed, which allows a rapid indication of Candida spp. fungi. The method makes it possible to obtain a preliminary result at 9 hours after inoculation of the pathology material in comparison with conventional methods. This nutrient medium is simple to be used and available for microbiological laboratories of various levels. 8 references, 6 tables. Keywords: yeasts of the Candida genus - rapid indication - oral pathology. Received January 26, 2012 UDC:573.6.086.83 STABILIZATION OF ANTIOXIDANT ACTIVITY OF PORPHYRIDIUM CRUENTUM MICROALGA EXTRACTS USING VEGETAL PREPARATIONS. Sadovnic Daniela. // Buletinul Academiei de Ştiinţe a Moldovei. Ştiinţele vieţii. 2012, No 2 (317), p. 141-148. The article considers the feasibility of employment of polyphenol additives isolated from grape (var. Cabernet) seeds as protective agents (stabilizers) of the antioxidant activity of the extracts from red microalgae Porphyridium cruentum. It has been found that 55%, 65% and 96% ethanolic extracts from grape seeds are capable to stabilize antioxidants produced from Porphyridium biomass when used at low concentrations. 17 references, 5 fi gures. Key words: Porphyridium - grape seeds – antioxidants – stabilizers Received March 27, 2012 UDC: 582.263.2:577.355.3:541.572.5:546.723 THE EFFECT OF SOME COORDINATION Fe(III) COMPOUNDS WITH α-AMINO ACIDS ON THE PHOTOSYNTHETIC PIGMENTS CONTENT OF MICRO- 197
