Description 678-686
Deviations in the biochemical composition and the formation of secondary metabolites have all been linked to the
metabolic fluxes that underlie plant resistance. The current investigation was undertaken to know the induced defence
against Lipaphis erysimi (Kalt.) via altered metabolic flux in Brassica juncea (L.) Czern. Pusa Mustard 30,
RH 749, NRCHB 101, DRMR 150-35, RH 0406, Pusa Mustard 27 and Pusa Vijay had higher levels constitutive
photosynthetic pigments, activity of constitutive enzymes and total glucosinolates, except in a few cases. However, due to
infestation by the L. erysimi, the levels of photosynthetic pigments and total glucosinolates significantly decreased, while the
activity of antioxidative enzymes and myrosinase increased. However, decrease in the photosynthetic pigments was
significantly higher in NRCHB 101, RLC 3, DRMR 150-35, Chattisgarh Sarson and Pusa Double Zero Mustard 31, except
in a few cases. Further, RH 725, Pusa Mustard 26, DRMR 150-35, NRCHB 101 and RH 0406 displayed significant
enhancement in the antioxidative enzymes, except in a few cases. Total glucosinolate content reduced significantly in Pusa
Mustard 26, DRMRIJ 16-38, NRCHB 101, DRMR 150-35 and RH 749, while the activity of myrosinase enhance notably in
Pusa Vijay, Pusa Double Zero Mustard 31, Pusa Mustard 25 and NRCHB 101. Present study displayed phytochemicals
defence against L. erysimi through shift in the levels of various pigments, enzymes and glucosinolate content. Cultivars RH
725, Pusa Mustard 26, DRMR 150-35, NRCHB 101 and RH 0406 showed significant variation the induced levels of various
phytochemicals and enzymes, thus cane be used in Brassica breeding programme.
