Published Paper Details:

The present paper deals with mineral contents in the leaves of Cochlospermum religiosum (L) Alston affected by Alternaria alternata fungus showing leaf blight symptoms. The mineral content was estimated by digesting healthy and infected leaves in Tri-acid. as prescribed by Toth et al.,(1948) method by Atomic Absorption Spectrophotometer (Thermo Fisher Scientific AAS -203 model),Spectrophotometer (Thermo Fischer Scientific UV 2100) and Flame Photometer Systronics-128 model). The element phosphorus was estimated by Sekine et al., (1966) method. Sulphur was estimated by Blanchar et al., (1965) method. The elements Sodium,Potassium and Calcium were estimated by Flame photometer, while Iron, Manganese, Zinc, Magnesium, Copper, Lead. Nickle was estimated by Spectrophotometer. The elements Manganse, Iron, Zinc and Sulphur were enhanced in the infected leaves of Cochlospermum religiosum (L) Alston, While Sodium, Potassium, Calcium, Magnesium, Copper, Lead, Nickle and Phosphorus contents were decreased in the infected leaves showing a high metabolic activity during pathogenesis.
