Potential Fertility of the Winter Buds in Clones of Variety Dimyat

Simeonov, I., Institute of Viticulture and Enology et al. [2012]

A study of the potential fertility of the winter buds in selected clones of variety Dimyat was conducted. It was found that there were no particularly large differences between most parameters of the potential fertility of the winter buds in variety Dimyat population and its clones. The more significant differences were found for the characteristics associated with the percentage of fruiting b ...

Response of Bulgarian Pepper Varieties to Causal Agent of Verticillium Wilt Verticillium dahliae Kleb.

Masheva, S., Maritsa Vegetable Crops Research Institute et al. [2012]

It was studied the response of nine Bulgarian pepper varieties to the agent of verticillium wilt Verticillium dahliae Kleb. during the period 2004 – 2006. The study was carried out on an artificial infection background verticillium plot. The experiment was set in the this area on alluvial meadow soil type by block method in three replications 5 plants in each replication. The disease was asses ...

Growing Response of Broccoli Seedlings in Mixture Enriched with Bioproducts in FLOATING System

Dincheva, Ts., Maritsa Vegetable Crops Research Institute [2012]

During the period 2009-2011 the ability to produce broccoli seedlings in FLOATING system was studied. The survey included three broccoli hybrids: Jade F1, Fiesta F1 and Coronado F1, for autumn production. Six variants of peat-perlite mixture 7: 3 vol/vol were evaluated. Four of them were enriched with bioproducts: Vermicompost – 100 l/m3; Humustim – 8.5 l/m3; Bionutrient – 330 ml/ m3; BactoFil ...

Studies on Development of Some Resistant Fusarium Tomato Genotypes in vitro

Dimanov, D., Institute of Tobacco and Tobacco Products et al. [2012]

The possibility of morphogenetic callus from three tomatoes genotypes resistance to cultural filtrate of two race fusarium has been explored. In the experiment, the food medium inducing morphogenetic callus has been optimised in the 3 genomes of tomatoes containing 3 α-NAA mg/l and 1 BAP mg/l. A Medium of 2 BAP mg/l is suitable for regenerating the tested genotypes tomatoes, the percentage of ...

The investigations were carried in the Institute of Forage Crops – Pleven, during the period 2009 – 2011. Dry seeds of the pea varieties E.F.B.33, Mir, Pleven 10 and Kerpo were irradiated with gammarays Cs-137 at the doses 40; 80 and 120 Gy. The data on emergence and survival shown that the relationship of dose/effect was valid in the variants irradiated with gamma-rays. With the highest perce ...
