Total
phosphorus content was tested from three different samples taken at
different times, first after 50 days of planting of the crop when there
was no disease appeared while second samples were taken from healthy and
diseased plant individually, almost 30 days after the first appearance
of the symptoms on late blight. Results revealed that there was an
overall increase in the quantity of phosphorus in all tested lines after
disease appearance. This increase was ranged from 6.0 to 41.8 percent
over the healthy plants of that same age group. Maximum increase of 41.8
percent in phosphorus content after disease appearance was observed
potato line FD 64-3, while 6.0 percent increase of phosphorus content
was observed in line SH 704. Increase in phosphorus content was also
observed in the healthy plants of all potato lines/cultivars which were
not infected by the disease but this increase might be due to aging
factor and was quit insignificant and unnoticeable. All though the
phosphorus content was slightly increased in the plants which were not
diseased than that of healthy plants which were tested at the time when
disease was not appeared. It is apparent from the above figures that the
increase in phosphorus content was more pronounced due to the effect of
late blight of potato and there was no or very slight effect of aging
was observed. Cite this article as: Subhani MN, Sahi ST, Rehman A, Wakil W (2014). Effect of late blight caused by Phytophthora infestans (Mont.) de Bary on Phosphorus in leaves of advanced potato lines/cultivars. Acad. Res. J. Agric. Sci. Res. Vol. 3(1) pp. 4-7
