Abstract:

During the greenhouse experiments were performed over a three-year period (2008-2010) at the Vegetable Research-Development Station Bacau - Romania, in order to evaluate the behaviour of species with multiple uses in the seedling stage to the soil-borne diseases attack, the following observations were made.

The attack degree was low at: Tagetes patula nana - 1,2%, T. tenuifolia – 0, Salvia. Splendens - 4,2%, Dahlia variabilis - 2.1%, Ageratum mexicanum - 3.1%, Ocimum basilicum - 1.1%, Zinnia elegans - 4.2%, Nicotiana affinis - 2.1% and Callistephus chinensis - 3.1%. These species have very good ability for growing in organic agriculture, in seedling stage. Some species of annual plants are attacked by soil-borne diseases. The attack degree was: Portulaca grandiflora - 18.9%, Petunia hybrida - 17.7%, Gazania splendens - 7.3%. Their ability for growing in organic agriculture is low. The behaviour of perennial plants was different: Gypsophila paniculata - 6.3%, Echinacea purpurea, 5.7%, and Chrysantemum leucantemum, 5.2%. Salvia officinalis had an attack degree of 15,6% and was sensible to attack from soil-borne diseases in seedling stage.
