Behavior of some Eggplant Varieties in the Vidra Area - Ilfov

The main purpose of the experiences organized at Research and Development Institute for Vegetable and Flower Growing Vidra was to evaluate the behavior of different cultivars of eggplants in specific soil and climate conditions of the Vidra area and to identify those with high yields, with quality fruits and tolerant to soil borne pathogens attack. In 2016, 12 cultivars of eggplants were studied: 6 non-hybrid varieties (Daniela, Luiza, Dragaica, Zaraza, Belona, Black Beauty) and 6 hybrids (Andra F1, Rebeca F1, Bibo F1, Clorinda F1, Mirabelle F1, Epic F1).The highest yield was achieved in Rebeca F1 and Luiza cultivars. The highest vitamin C content was realized at Rebeca F1, Luiza, and Zaraza cultivars. The Mirabelle F1 hybrid and Black Beauty variety presented a reduced sensitivity to Verticillium dahliae and Fusarium oxysporum f. sp. melongenae

Behavior of some eggplant cultivars (Solanum melongena L.) at the pathogens attack in greenhouse and field

The experiences organized at RDIVFG. Vidra in 2016 had as main purpose the assessment of different varieties and eggplants hybrids on the specific soil and climate conditions in the Vidra area. Six eggplant cultivars were studied, 3 romanians created at RDIVFG Vidra (Belona, Andra F1 and L (Luiza x Pop Unirea) and 3 foreign (Estelle F1, Sharapova F1 and Madrid F1) in greenhouse and field. There were made assessments regarding the occurrence and evolution of the pathogen attack (Botrytis cinerea, Alternaria solani and Verticillium dahliae) in correlation with the environmental factors, the frequency and severity of the attack on the basis of which it was calculated the degree of attack. Also, observations have been made on the number of fruit per plant, the average fruit weight, yield and fruit quality. Among Romanian cultivars, the best yield was obtained at Andra F1 7.35 kg / sqm in greenhouse and 6.26 kg / sq m in the field. Among the foreign hybrids, have been highlighted Sharapova F1 with 9.04 respectively 7.8 kg / sq m yield and Estelle F1 with 8.44 respectively 6.63 kg / sq m in greenhouse respectively in the field. In greenhouse the average yield was higher with 10.1 t / ha comparatively with the field, and the quality I of yield was higher with 10.4 t / ha. The most sensitive hybrid of Verticillium dahliae (verticillium wilt) is Sharapova F1 (FA = 36.4%; GA = 15.9%), followed by Madrid F1 (FA = 36.4%, GA = 13.6%) and Estelle F1 (FA = 27.3%, GA = 18.2%). Among the varieties / hybrids created at RDIFG Vidra, Belona was not attacked by Verticillium dahliae and Andra F1 showed a low sensitivity

Areas cultivated with eggplants occupy a very large surface in greenhouses and greenhouses, after tomatoes, peppers and cucumbers. The rootstocks assure to the eggplants high productivity, high quality of fruits and resistance/ tolerance to diseases and pests. The biological material was represented by eggplant cultivars Luiza and Aragon F1 and rootstock Torvum vigor. The purpose of the experience was to study the rootstock's influence on the growth, fructification and resistance to pathogens and pests of grafted eggplants.Eggplant plants grafted on Torvum vigor had a 19.8%higher vigor than Luiza and 25.2% Aragon F1 non-grafted. The yield was higher in grafted plants with 18.5% to Luiza cultivar and 17.8% to Aragon F1 compared with non-graftedvariant. The Torvum vigor rootstock gives to graftedplants a high resistance to the attack of soil pathogens Verticillium dahliae and Fusarium oxysporumf.sp. melongena

RESEARCH CONCERNING THE BEHAVIOUR OF SOME EGGPLANT(SOLANUM MELONGENA L.) GENOTYPES IN VIDRA, ILFOV REGION

Researches undertaken were aimed to verify the behavior of some varieties and hybrids of eggplant in conditions of soil and climate of the Vidra area. The cultivars were studying in terms of earliness, yield and resistance of the attack of soil born pathogens. There have been studied 12 genotypes of eggplant: 6 varieties and 6 hybrids. The cultivars Epic F1 and Daniela were the earliest and the variety Black Beauty and the F1 hybrid Mirabelle the latest. Average fruit weight ranged from 250 g (Belona) and 560 g (Rebeca F1). The yield ranged from 38.2 t /ha (Bibo F1) and 51.0 t /ha (Rebeca F1). Attack of soil born pathogens Verticillium dahliae and Fusarium oxysporum f. sp. melongenae started since the I decade of September. Verticillium dahliae attack was the lowest in cultivars: Belona, Black Beauty and Mirabelle F1 and the high attack was recorded on Luiza, Rebeca F1 and Epic F1

Effect of Nutritive Media and PH on in vitro Mycelial Growth of some Pleurotus eryngii Strains

The mycelial growth rate of 4 strains of Pleurotus eryngii was first studied on different culture media - MEA, PDA and WEA (wheat extract agar). In the next experiment, we checked the mycelial growth on the same medium but at 3 different pHs. MEA medium ensured the highest growth rates for all the strains under test, followed by PDA. Pery-G strain showed the fastest growing rate on MEA (5.79 mm day-1) and PDA (3.04 mm day-1), respectively. Test concerning the mycelium growth on PDA at different initial pH values (5.5, 6.0, 6.5) showed the preference of our P.eryngii strains for media with weak acid to the neutral reaction , the optimal values being 6.0. There were no big differences among mycelium growing rates of the same strain for the three pH variant
