Pharmacognostical and Phytochemical Screening of Bauhinia variegata Linn leaves

ABSTRACT Pharmacognostical characters of the leaves of Bauhinia variegata Linn was studied which showed the presence of thin walled epidermis, parenchymatous cells, abundant solitary calcium oxalate crystals, vascular bundles and multicellular covering trichomes. Leaf constant viz., stomatal index -5.27, vein islet number -8.3, vein termination -6.6, palisade ratio -7.6 were also studied. Physiochemical parameter such as total ash -8 % w/w, water soluble ash value-2 % w/w, acid insoluble ash value -6 % w/w, alcohol extractive value-8 % w/w, water soluble extractive value -18.4 % w/w and loss on drying -7 % w/w were also determined. Phytochemical screening showed the presence of steroids, saponins, flavonoids, alkaloids and tannins

DISEASE DETECTION IN TREE LEAVES AND FRUITS USING IMAGE PROCESSING TECHNIQUES

India is the agriculture based country. Now a day, agricultural product yield is decrease for the reason of disease affect the plants like fungus, virus diseases. In this paper, we detect the tree leaves and fruits disease using image processing techniques. In this paper apple, grapes and pomegranate disease are detected. The apple diseases are apple scab, apple rot, Marssonina leaf blotch, black rot canker, apple mosaic. The grape diseases are black rot, powdery mildew, downy mildew, anthracnose, bacterial leaf spot, and rust. The pomegranate diseases are bacterial blight, aspergillus fruit rot, anthracnose, cercospora fruit spot, cescospora leaf spot
