Abstract:
Lesion sizes in leaves of Nicotiana tabacum cv. xanthi-nc treated with polyacrylic acid (PA), and showing 60% reduction in lesion numbers, did not differ significantly from those in untreated control plants. Protoplasts isolated from treated plants did not differ significantly in % infection or in the production of infectious virus at 24 or 48 h after inoculation in vitro, compared to the controls. Polyacrylic acid treatment was shown to have a differential effect on the susceptibility of xanthi-nc plants grown in different light intensities; highest resistance was induced in plants grown in low light. A study of the water relations of low light grown plants indicated increased osmotic potential and decreased pressure potential, compared with the controls. The transpiration resistance of treated plants was increased. Spraying of treated plants with an antitranspirant abolished PA-induced resistance. It is suggested that PA treatment may interact with the plant mechanism(s) affecting susceptibility to virus infection. © 1978.
