Эффективность использования различных криопротекторов для разбавления и сохранения семени хряка ДАРИЙ, Григорий; ГРАНАЧ, Вера; МАРАНДИЧ, Елена Для длительного хранения семени хряка при комнатной температуре испытаны три антиоксиданта. Лучшие результаты показал антиоксидант М 22 (оплодотворяемость свиноматок от первого осеменения 77,8 %). Разработанный вариант среды может быть использован для разбавления и хранения спермы хряка при температуре 16-18°С в течение 5-7 дней, не снижая оплодотворяемости свиноматок.

The assessment of the impact of the eco-pedological conditions on cherry trees in Rudi village, Soroca district MOCANU, Emilian; MELNIC, Rodica; BACEAN, Ion The purpose of the research was to give the physical and chemical characteristics of the investigated soils, which are located on slopes with different inclination. Also was the evaluation of the cherries productivity on these soils. Cherry tree has high demands on soil structure and drainage. The best for this species are medium and light soils, permeable, depending on the humidity, which are easily heated and contain up to 4 - 6% active calcium. When planted in clay, heavy and cold soils, the cherry grows weak, suffers from frost, has glue leaks and lives little. It is one of the fruit species most sensitive to root suffocation, does not withstand stagnant water and flooding, even for short periods. Also, the cherry tolerates the insufficient water in the soil. On soils with advanced erosion, the cherry vegetates greedy and lowers fruit. The cherry gives good results on soils with a pH value of 5.2 - 7. The most favorable location for the cherry is in the middle third of the slope.; Scopul cercetărilor a fost de a determina caracteristicile fizice și chimice ale solurilor din zona studiată, care sunt situate pe pante cu înclinație diferită, precum şi evaluarea productivității arborilor de cireș ce cresc pe aceste soluri. Cireșul are cerințe mari în ceea ce privește structura și drenajul solului. Cele mai bune pentru această specie sunt solurile medii și ușoare, permeabile, în funcție de umiditate, care se încălzesc ușor și conțin până la 4-6% calciu activ. Când este plantat în soluri argiloase, grele și reci, cireşul crește slab, este sensibil la îngheț, suferă de scurgeri de clei și are o durată de viaţă scurtă. Cireşul este una dintre speciile de pomi fructiferi cele mai sensibile la sufocarea rădăcinilor, nu rezistă la apă stagnantă și inundații, chiar și pentru perioade scurte. În schimb, cireșul tolerează umiditatea insuficientă din sol. Pe solurile cu eroziune avansată, cireşul vegetează slab și fructifică puţin. Cireșul dă rezultate bune pe solurile cu valoarea pH-ului de 5,2 - 7. Locația cea mai favorabilă pentru cireș se află în treimea mijlocie a pantei.

Tetraploid maize - a new model for research in the field of ecological genetics BATÎRU, Grigore; COMAROVA, Galina The increase in the frequency of dry vegetation seasons in Moldova in recent decades determines the need to expand the range of research work on agroecology, in particular, in the field of ecological genetics. Specificity of understanding ecological genetics involves studying the genetic basis of variability and inheritance of adaptive plant reactions occurring at different levels of biological organization. In the present work it was suggested to use genomic (by tetraploid chromosome set) and gene (by the opaque-2 gene) mutations of maize as a contrast material for studying the adaptive response to various types of modeled drought. The results of the response of genomic mutants of maize in the process of ontogenetic development to various types of simulated drought are discussed: soil, air, and complex. The comparative study of the complex of physiological and biochemical parameters, such as the germination capacity, the content of photosynthetic pigments, the water-retaining capacity of the leaf apparatus, the leaf thickness stability coefficient, etc., allow us to identify specific features manifested by changing the genomic set of different maize genotypes, that in perspective expands the variation of germplasm for the selection of maize for drought resistance.

Algorithm for creating electrophoretic passports of maize hybrids ADAMCIUC, Arcadii; BATÎRU, Grigore; COMAROVA, Galina; BOUNEGRU, Serghei; ROTARI, Eugen One of the topical issues of seed production in the Republic of Moldova is the timely export of hybrid maize seeds and ensuring their quality. In this regard, it is necessary to involve the latest methods of express diagnostics of hybrid purity of the- se seeds and their passportization in order to be able to carry out their objective and adequate certiȀcation.
