A laboratory study was undertaken to ascertain the impact and the extent of feeding by different pests on biochemical constituents
and various enzyme levels in rice plants. The difference in these parameters due to the pest damage by three different modes
of feeding was also studied and compared. The borer pest—yellow stem borer (YSB), Scirpophaga incertulas (W); surface feeder—-leaf roller (LR), Cnaphalocrosis medinalis (G) and a sucking pest—brown plant hopper (BPH), Nilaparvata lugens (S) fed rice plants were analyzed for the quantitative and qualitative changes in biochemical profile and enzymatic changes
that occur as plant’s defensive responses were analyzed spectrophotometrically. The phenolic acids were analyzed using HPLC
and quantitated with the standard samples. The quantity of biochemicals such as proteins, phenols and carbohydrates has been
enhanced along with the enzyme activities of peroxidase (POD), catalase (CAT), chitinase (CHI). A decrease in superoxide dismutase
(SOD), phenyl alanine ammonia lyase (PAL), β-1, 3-glucanase (GLU) enzyme activities were evident in pest infested plants.
Phenolic acids like vanillic acid, syringic acid, cinnamic acid, and p-coumaric acids were mostly found in the infested plants. We demonstrate that the elevated levels of biochemicals, phenolic
acids, and enzymes may play a major role in plant defense. 相似文献
