Abstract:

The experiment was carried out to assess the biochemical basis of resistance in response to the infestation by brown planthopper (BPH), Nilaparvata lugens (Stal) and white backed planthopper (WBPH), Sogatella furcifera (Horvath) in transplanted (TPR) and direct seeded (DSR) rice ecosystem. The changes of various biochemical constituents such as total sugars, free phenol and soluble protein, were assessed spectrophotometrically in two rice ecosystem before and after planthopper infestation. The estimation of biochemical constituents in both ecosystem of rice was done to establish the relationship between various biochemical contents and to compare it with resistance. The results revealed that the higher level of total sugars was observed in TPR ecosystem compared to DSR. The amount of phenols and soluble proteins in DSR was found higher compared to TPR. Total sugar content shows significant positive relationship with plant hoppers in TPR. Whereas, free phenols and soluble protein were showed negative correlation with planthoppers in DSR at 90 DAS. However, the amount of phenol and soluble proteins were related to resistance.
