Abstract
Indices of amounts of weather fleck were evolved from field inspections of flue-cured tobacco subjected to variable amounts of irrigation water. The susceptibility of tobacco leaves to weather fleck increased with maturation, reaching a maximum when they became mature. Occurrence and intensity of the disorder were found to be directly related to amounts of incident water, which hastened leaf maturity and rate of plant growth.Keywords
