Potato (Solanum tuberosum L.) is one of the most important food plants worldwide and holds over 18.6 million ha all over the world (FAO, 2011). In Romania, potato crops occupied areas between 250 and 300 thousand hectares after 1950, ranking 18th in the world and 2nd - 3rd in Europe in terms of total tuber production. The expansion of potato crops, including in southern Romania, is based on the extensive research conducted under ICAR between 1950 and 1967 and ICCS Brasov in 1967. Research conducted on the chromic luvosoil of Moara Domneasca Didactic Farm in 2013 aimed at checking the suitability of three potato varieties for the conditions of the area - Riviera, Bellarosa and Everest; the varieties were grown both as a non-irrigated and moderately irrigated crop (at a hydric regime specific to the normal one in the area). Observations and measurements were made on the emergence and development of plants, tubers, tuber production and commercial quality. In 2013, the variety Bellarosa achieved a maximum tuber yield 29,203 kg/ha, of which 25,494 kg/ha were tubers over 55 mm in size.

REPRESENTATIVES OF GENUS AEGILOPS AS A SOURCE OF PATHOGENS RESISTANCE

Published in AgroLife Scientific Journal, Volume 3, Number 1
Written by Hristo STOYANOV

The main purpose of breeding programs is to obtain high yields of common winter wheat (Triticum aestivum L.). Development of new lines and varieties resistant to economically important diseases related to the yield, is associated with proper selection of the initial breeding material. Most of the phylogenetic species closest to bread wheat, such as representatives of the genus Aegilops, possess valuable genes for biotic stress resistance. To establish appropriate accessions which could be involved in the hybridization and breeding programs of bread wheat, 32 accessions of the genus Aegilops (10 of Aegilops cylindrica, 12 of Aegilops tauschii, 6 of Aegilops ventricosa, one of the species Aegilops ovata, Aegilops neglecta and Aegilops speltoides) were observed, as regards their resistance to the pathogens of powdery mildew (Erysiphe graminis), brown rust (Puccinia recondita) and septoria leaf blight (Septoria tritici). The observation was conducted under field conditions in the ear formation stage. All studied accessions were completely resistant to the pathogen of septoria leaf blight (Septoria tritici). All accessions of Aegilops cylindrica, 3 of Aegilops tauschii and 2 of Aegilops ventricosa were susceptible to powdery mildew. Accessions of Aegilops cylindrica and also 8 accessions of Aegilops tauschii and 3 accessions of Aegilops ventricosa are susceptible to brown rust. Accessions of Aegilops ovata, Aegilops neglecta and Aegilops speltoides are completely resistant to the three pathogens. With the highest complex resistance are accessions AE192, AE1609 and AE20 compared to other accessions of Aegilops tauschii and Aegilops ventricosa. The combination of high complex resistance to diseases, and a large phylogenetic proximity with genus Triticum, makes Aegilops tauschii and Aegilops ventricosa valuable sources of genes for resistance which could be successfully transferred into different wheat species.

In this paper we present our results concerning further screening for optimal concentration of dispersant (Nacol C), nutrients and diesel oil to sustain metabolic activity of marine autochthonous microbiotain order to enhance the biological consumption of diesel oil. The results show that the overall metabolic activity (reported as ng reduced resazurine/hour/wheel), is decreased by diesel addition (10% final “concentration”) either in the absence or in the presence of dispersant (Nacol C 1/10.000 dilution); inorganic nutrients additions (both ammonium acetate and ammonium phosphate 0.5%) greatly (4 to 10 times) increase the rate of resazurine reduction whereas further organic nutrient addition sustains an even higher rate of resazurine reduction. Diesel oil consumption is 1.5 times enhanced by dispersant addition but organic and/or inorganic nutrients additions do not have a further effect on diesel consumption, the values obtained being within the level of standard deviations.

Selenium is a microelement necessary for normal growth, development and reproduction. In our research on carp at intensive breeding, we followed up the effects of selenium supplementation on the activity of the selenoenzyme glutathione peroxidase (in erythrocytes and in liver) and type I deiodinase (in serum). The experiments were performed in experimental pools in the fish farm “Boshava” during 2010, by introduction of inorganic (sodium selenate) and organic selenium (selenium starter) in supplemental food for young carps (0+). That way, at the end of the experiment a statistically significant length and weight growth was noticed in the youngsters’ groups fed with selenium supplemented food, compared to the control group fed without selenium supplement. Low mortality in the pools where selenium enriched food was implemented must be particularly pointed out. Mortality in the control group was 17.5%, in the group with inorganic selenium supplement 12.3%, and in the group with organic selenium supplement only 0.7%. In laboratory conditions we followed up the influence of cadmium in water (1.5 mg/l) on the activity of the enzyme glutathione-S-transferase, an enzyme important in the biotransformation of various pollutants. The activity of this enzyme is in correlation with the activity of the selenium-dependent enzyme, glutathione peroxidase. In relation to the control group, in the groups supplemented with selenium an increase of glutathione peroxidase activity in erythrocytes and liver was found, with simultaneous decrease of glutathione-S-transferase activity in carps’ plasma and liver.

Using the process of breeding, the native apple varieties well adapted to the climate of Romania can be an interesting premise for inducing natural genetic resistance to Venturia inaequalis. This paper aims to study in detail the terms of phenological and molecular tools a few Romanian old apple varieties, ('Prescurate', 'Gurguiate', 'Săciu', 'Venchi', 'Turnu', 'Calvil alb', 'Sângeriu', 'Iridium' etc) who showed in prior in the field conditions a natural genetic resistance to scab and after these studies could be reconsidered and reassessed in new breeding programs in Romania. For the beginning the screening with molecular markers to highlight the presence or absence of Vf gene, is the first step in reconsidering these old varieties of apple.

According to the FAO statistics and reports (2013) in the next 30 years the world's urban population will double and more than 60% of it will live in cities. Appropriate measures will be needed to ensure food and one of the key measures that address these changes is the development of policies, strategies, techniques and appropriate support mechanisms for sustainable management system for urban agriculture/horticulture, including permaculture.In this context, it was realized multidisciplinary research at UASVM of Bucharest and based on the results obtained were recommended varieties Deea, Elita 124 and Roxia from the species Ribes nigrum L. (black currant), Rolan, Jh. Van Tets from the species Ribes rubrum L. (red currant), V2 biotype from species Lycium barbarum L. (wolfberry) and Rares, Valeria, Carmela, Viorica, Bucovina, Ilinca from species Prunus armeniaca L. (apricot) that can be grown in urban and suburban gardens.Making them suitable for the characteristics of these varieties and biotypes are referring to: earliness of fruiting, production obtained in ecological conditions, low to medium volume of shrubs and trees, plant density per unit area, self compatibility in a high proportion of gametes and quality and organoleptic characteristics, biochemical and sanogene of fruits.Among the biochemical and sanogene characteristics, dry matter levels were high (15% blueberry,17% wolfberry and 22% apricot), vitamin C (24 mg/100 g in apricot, 60 mg/100 g wolfberry), flavonoids (1.12 mm rutin/ml currant), polyphenols (200 mg galic acid/100 g wolfberry), antioxidant capacity (48 RA% in wolfberries).
