abstract
Host plant resistance to yellow mite was studied by quantifying phenols, sugars, protein, proline and enzymes such as peroxidise and phenylalanine lyase in chilli varieties. Damage by yellow mite, Polyphagotarsonemus latus (Banks) and resistance in chilli germplasms had higher levels of total sugars and protein contents to encourage the mite infestation in susceptible chilli entries, while chlorophyll contents in leaves did not show any relationship with mite infestation levels. Consequent to mite infestation, the levels of phenols, proline, peroxidase and PAL were found enhanced (16.80 to 22.80 mg/g; 4.42 to 6.54 µ moles/g tissue; 825 to 1362 units/g of tissue; 3.20 to 4.67x10³Âµmoles/min/ml), might be due to induced resistance or hypersensitive reaction, particularly in resistant entries namely, Aparna, S 49, BVC 47, BVC 53 and Capsicum frutescence compared to susceptible entries which can be correlated to level of resistance to yellow mite.
