Abstract:

During 2009-2010, greenhouse experiments were performed in Vegetable Research-Development Station Bacau – Romania, in order to evaluate the vegetable varieties and lines resistance to the soilborne disease attack both in mature and in seedling stage. The study was focused on the following vegetable species: tomato, cabbage, lettuce, pepper, egg plant and celery. The results obtained on sets of trials were as follows:

  • Thetrials: 01 – 101 in tomato
    • The tomato cultivars tested in the present study are recommended for cultivation in ecological agriculture.
    • The plants free of soil-borne diseases attack were Katerina and Bonavista.
    • The lowest degree of attack was in: Siriana, Venezia, Birdie, Bobalna and Unibac, 1,2 – 7,3 %.The percentage of health plants were 92,7 – 98,8 %.
    • A medium degree of attack was determined at: Belavista (9,4 attack degree).
  • The trials: 01 - 102 in cabbage
    • The degree of attack in Isalnita variety was low - 3,6%. The results obtained proved that 96,4% were healthy.
  • The trials: 01 - 103 in lettuce
    • The degree of attack was 7,2% and the percentage of health plant was 92,8%.
    • The lettuce variant had good ability for cultivation in organic agriculture.
  • The trials: 03 – 104 in pepper
    • The following varieties of pepper: Siret, Creola, Dariana Bac, Beladona, Verdrana and Salsa were very resistant to attack of diseases in seedling stage.The percentage of health plants was above 98,4%.
  • The trials: 01- 105 in eggplant
    • Edna hybrid and Contesa variety are indicated for cultivation in organic agriculture. Only 2,8% plant of Edna and 5,2 % plant of Contesa were sensible to soil-borne disease attack.
  • The trials: 03 - 106 in celery
    • The attack of soil-borne diseases of celery was very small. Bistrita variety has very good ability for organic agriculture, the percentage of health plant was 96,4 %.
