ABSTRACT

Host defence mechanisms can be elicited by using different elicitors produced from the pathogen/host. In this study, an effort has been made to study the effect of two fungal elicitors derived from Aspergillus spp. and A. parasiticus on induction of various defence related enzymes in Chilli. Foliar application was done on 20-days-old Chilli plant with 10% A. parasiticus fungal culture filtrate (APFCF) as elicitors to trigger systemic acquired resistance (SAR). As a response of SAR, an increase in activities of phenylalanine ammonia lyase (PAL), Total protein content, Total phenol content, Germination in form of vigor index were found highest on 4th day after treatment (DAT) in comparison with the control plants. The treated plants showed enhanced growth and development as well as increase in yield. About 100% survival rate was found in Chilli seeds treated with Aspergillus spp. and APFCF than control. The enhanced activities of defence enzymes and elevated protein, phenol, chlorophyll content in treated Chilli plants suggest the induction of SAR against Aspergillus spp and A. parasiticus by using the same fungal elicitors. Keywords: Aspergillus parasiticus, Capsicum frutescens (Chilli), Aspergillus parasiticus fungal culture filtrate (APFCF), Phenylalanine ammonia lyase (PAL), Enzymes
