ASSOCIATION OF BIOCHEMICAL FACTORS IN RICE AGAINST INFESTATION OF RICE LEAF FOLDER, CNAPHALOCROCIS MEDINALIS (GUENEE) (LEPIDOPTERA : PYRALIDAE)

摘要

The estimation of biochemical constituents viz., total sugars, total phenols, crude protein and total free amino acids in rice leaves collected from 30 day old plants of different resistant and susceptible genotypes was carried to establish the relationship between various biochemicals with the resistance/ susceptibility. The results revealed that the amount of total sugars, crude protein and total free amino acids in all susceptible genotypes was found higher compared to resistant genotypes. Whereas, the higher amount of total phenols was observed in all the resistant rice genotypes compared to the susceptible genotypes. However, the amount of total sugars, total phenols, crude protein and total free amino acids were not related to resistance. Hence, many of the resistant rice genotypes recorded comparable proportion of these bio chemicals.
