Author(s): Sandeep Kumar, VP Chaudhary, Veer Singh and Krishna Kumar
Abstract: Biochemical studies of plant pathogen interaction revealed that soluble sugar, starch, chlorophylls, phenolic and tannin content were observed higher level in healthy leaves compared to pathogen infected leaves. Only scanty information is available for biochemical changes in coriander plants during the growth of Protomyces macrosporus. The aim of this study was to increase knowledge regarding the physiological and biochemical changes during the occurrence of stem gall disease and try to define changes in phenols, flavonoids and tannins that might be related to the potential antioxidants and may be efficient as preventive agents in the pathogenesis of same disease. The experiments were conducted during 2016 at Plant Pathological laboratory and Vegetable Farm, Department of Vegetable Science, Narendra Deva University of Agriculture and Technology, Narendra Nagar, Kumarganj, Ayodhya (U.P.) with four treatments and three replication. Biochemical studies were revealed that total phenol content was highest in healthy plant parts (2.97-6.20 µg/g) as compared with infected plant parts (2.53-5.58 µg/g). Total tannin content was found highest in leaves (3.29-3.92 µg/g) and lowest in inflorescence (2.31-2.79 µg/g) in both stem gall infected and healthy plants, flavonoids content in healthy plant parts was (0.98-1.47µg/g) as compared to infected plant parts (0.77-1.07 µg/g). Whereas saponin content was 0.99-1.80% in infected plant and 1.93-2.16% in healthy plants of coriander.
