Abstract

Data on the viral load distribution by different leaves parts (upper, middle, lower leaves) in cucumber plants grown in protected ground are presented. Studies were conducted at the time of the visible infection manifestation. It was revealed that accumulation of virions of the cucumber green mottle mosaic virus (CGMMV), with the onset of manifestation, prevailed in the middle and lower leaves, which is probably due to the “slow” redistribution of the virus along the external phloem. This pattern is confirmed by a high correlation coefficient (r Data on the viral load distribution by different leaves parts (upper, middle, lower leaves) in cucumber plants grown in protected ground are presented. Studies were conducted at the time of the visible infection manifestation. It was revealed that accumulation of virions of the cucumber green mottle mosaic virus (CGMMV), with the onset of manifestation, prevailed in the middle and lower leaves, which is probably due to the “slow” redistribution of the virus along the external phloem. This pattern is confirmed by a high correlation coefficient (r = 0,99). It was also found that the viral load indicator has high variability (Cv = 63,77 = 63,77%). A similar coefficient of variation may indicate the fact that under constant environmental and nutritional conditions, which are provided under the conditions of protected ground, the individual susceptibility of cucumber plants to the phytopathogen affects the number of viral particles in the plant.
