Abstract
During 2013 - 2014, greenhouse experiments were performed in Vegetable Research-Development Station Bacau - Romania, in order to evaluate the vegetable categories of multiplication at the soil-borne diseases attack in seedling stage. Experiments on round pepper (Creola), long pepper (Ionel) sweet pepper (Dariana Bac) and tomatoes (Unibac) were performed to compare the category: CA, CSD, PB, BS and C1 that presents soil-borne diseases attack. Experiments on Levisticum (Rarau) were performed to compare CA and C1 that presents soil-borne diseases attack. The attack on B and C1 generations at round pepper was between 0,3 - 0,7%. The plants of CA and CSD category after emergence were susceptible at soil pathogen attack (1,3 - 1,7%). The percentage of healthy plants was 98,3 - 99,7%. Long pepper - Ionel was tolerant to soil pathogens attack (CA - 0.3% CSD - 0.3%, PB - 0.1%, B - 0.1% C1 - 0). Sweet pepper showed a light susceptibility to soil pathogens attack after emergence: CA - 3.3% CSD - 3.3%, PB - 2.1% BS - 2.4% C1 - 2.1%. After transplanting in cell plastic trays the pathogen attack stopped. Lovage - Rarau presented a low attack of soil pathogens, behaving as a rustic species, resistant to low temperatures and soil pathogens attack. In both categories of multiplication the attack did not exceed 0.3%. The tomatoes due to low temperatures during emergence (8-20OC) had an uneven emergence, being infected with soil pathogens. There are differences between the attack depending on the category of multiplication: CA - 1,2%, CSD - 1,0%, PB - 0,5%, B - 0,7%, C1 - 1,0%.
