The aim of the present research work was the screening of the effect of the main cytokinin (BAP, kinetin or zeatin) in different concentrations and combinations with the auxin NAA on androgenesis of white cabbage anthers cultivated in vitro. The results obtained are regarded as an intermediary stage for the development of a reproducible protocol

Lemon balm (Melissa officinalisL.) is a medicinal plant with a long history in traditional medicine. Classical propagation of this species is inefficient for establishing a good quality clonal plants. The aim of this work was to elaborate an in vitro propagation protocol for M. officinalis using apexes and uninodal fragments as explants. The highest multiplication

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a pest native from South America, which was first reported in Romania in 2009 (Satu Mare). Among the vegetable species, tomatoes are the main host of the pest, but can also be found on potato, black nightshade (Solanumnigrum), eggplant, bell peppers and tobacco.Yield losses caused by Tuta absoluta can

The experiment was carried out in 2020, under high plastic tunnels conditions, using the tomato hybrid Prekos F1 and aimed to evaluate the efficacy of different combinations of fungicides with insecticides for complex control of pathogens Alternaria solani (early blight), Fulvia fulva (leaf mold) and pests Tuta absoluta (tomato leaf miner) and Helicoverpa armigera (cotton

The present study aims to identify combinations of active substances for the complex control of pathogens and pests on eggplant crops in the field. The experiments were conducted between 2016 – 2017, in field conditions, using the variety of eggplant Luiza and the following experimental variants: V 1 – Acrobat MZ 69 WG 0.2% +

Psylla and fire blight resistance combined with fruit quality are still pearbreeding aims at Research Institute for Fruit Growing (RIFG) Pitești, Romania. The new pear cultivar ‘Pandora’ was registered in 2019, being released by interspecific hybridization between ‘Euras’ cv. [(PyrusserotinaxOlivier de Serres) x Doyenne d’hiver] and ‘Tse Li’ cv. (P.ussuriensis). The trees are medium vigor,

The study presents the behaviour of 28 apricot cultivars planted in 2017 in the Experimental Field of the Faculty of Horticulture within the University of Agronomic Sciences and Veterinary Medicine of Bucharest. The foreign cultivars grafted on Myrobalan 29C, Saint Julien A and GF 677, were planted at 4.5 x 1.5 m and 3.5 x

The aim of this study was to assess the yield and fruits quality of plum produced in ecological system.In 2019-2020 periods the influence of different fertilizers (Biohumus, Macys BC 28 and Cifamin BK) on yield and fruits quality at three plum cultivars (‘Centenar’, ‘Tita’ and ‘Stanley’) was carried out in a demonstrative plot from Research

The paper presents a 2-years study of the valuable characteristics in four foreign apple cultivars grown in northeastern Romania, named Moldavia area. The phenological stages, quality traits of fruits and some chemical parameters were evaluated. Start flowering was determined at April 17th (’Resse’), while end of flowering was identified the period April 27th -28th. Period

Grape pomace is a by-product obtained from the technological processing of grapes and represents on average 20% of the total amount of grapes taken for winemaking. Due to the medical, food and cosmetic interest in the valorisation of grape pomace, the present study presents the percentage of pomace resulting, the yield of must and the

Over time at Research and Development Stationfor Viticulture and Oenology Odobeşti, numerous intra- and interspecific sexual hybridizations have been carried out, in order to obtain new cultivars, with high productive and qualitative potential, with disease tolerances, resistant to stress factors, very well adapted to the climatic conditions specific to Vrancea vineyards.Thus, valuable hybrid elites were

The Dragasani vineyard is one of the most ancient existing in Romania being famous for obtaining red and white wines of the highest quality. The present study has performed during five years (2005-2009), focusing on the anthocyanin profiles of the autochthonous Novac grapevine cultivar, in comparison with Cabernet Sauvignon cultivar which, also provides wines of

A study concerning the influence of climatic conditions on the oenological parameters of wine cultivars was carried out using six wine cultivars under the climatic conditions of 2019. Wine samples were taken from Ştefăneşti–Argeş, Babadag and Drăgăşani viticultural centres. Determination of the oenological parameters has been made for the following wine cultivars: Riesling Italian, Fetească

Climatic accidents increase in frequency due to climatic changes. Hailstorms are typically localized events and are known few studies about their effect on grapevine. The objective of this study was to examine the vine vegetative balance responses to natural hail, registered when shoots were 10-15 cm height. Four grape cultivars (Vitis vinifera L.), two for

The aim of the present study was to investigate the production of extracellular enzymes in a number of twenty six autochtonous Saccharomyces and non- Saccharomyces strains selected in Dealu Mare region for wine production. The strains were screened for the production of extracellular b-glucosidase, esterase, pectinase and protease activity by inoculation the yeast strains onto

The determination of metals in different type of wines is of high importance for the nutritional, as well as toxic effects of these elements. The main purpose of this research is to determine the concentration of Cu, Fe, Mn, Cd, Zn and Pb in wine. The analyzed samples were wine samples obtained under micro-vinification conditions

The climate changes in Murfatlar vineyard in recent years consist inthe increase ofmonthly average temperatures, recorded in both cold and warm seasons, accompanied by an irregular distribution of rainfall during the year, which significantly influences the growth of grapevine, the quality and production of grapes.Six representative cultivars were studied, three for white wines: Chardonnay, Columna

non-Saccharomyces yeasts isolated from different stages of the natural must fermentation process. Screening of extracellular enzymatic activities was performed on agarized media in which the following substrates were added: arbutin, cellobiose, Tween 80, tributyrin, casein and citrus pectin, to highlight the activity of enzymes: ßglucosidase, esterase, lipase, protease and pectinase. Among the 30 Saccharomyces cerevisae

The influence of climatic factors on grape yield, fertility indicators of grapes (absolute coefficient of fertility, relative coefficient of fertility, absolute productivity indices, relative productivity indices), but also sugar and total acidity content in three cultivars of ‘Fetească’ (‘Fetească Albă’, ‘Fetească Neagră’ and ‘Fetească Regală’, respectively) was evaluated during 2016-2020 2016 period at the experimental

Chrysanthemum is one of the major crops in the word and it is grown for two basic ways for cut flowers and potted plants, depending of market demand. In the last years the cultivated areas with Chrysanthemum have gained a significant growth. Also, due to the progress made in the selection of chrysanthemum, in order

Trees irrigation is one of the major activities because the fruit production is proportional to water use. The current decrease of water resources leads to the urgent need to adopt a strategy which could be applied to efficiently utilize water without affecting the growth, yield and fruit quality. Therefore, deficit irrigation is an alternative. The

The objective of the study was to evaluate some postharvest parameters of fruit quality at seven strawberry cvs., (‘Alba’, ‘Clery’, ‘Coral’, ‘Magic’, ‘Premial’, ‘Queen Elisa’, ‘Record’) grown at RIFG Pitești, Romania in open field, in the 2016-2018 period. The storage method included three days in normal refrigeration condition (2-4ºC) followed by one day at room
