Abstract
The cell suspension cultures of Capsicum frutescens were treated with two signalling compounds, salicylic acid (SA) and methyl jasmonate (MeJA), individually, and in combination. SA and MeJA were found to individually enhance capsaicin production, but when administered in combination there was no further enhancement in capsaicin production. Both the signalling compounds were also found to result in higher leaching of capsaicin into the medium. The endogenous polyamine (PA) levels were higher in the treatments with SA and lower in the treatments with MeJA. The endogenous PA levels were found to be the highest on the sixth day of culture, after which the ethylene levels were found to increase. Maximum ethylene production was on the 12th day of culture, coinciding with the highest capsaicin production. The correlation of capsaicin synthase levels and the increase in capsaicin production was also observed on the 12th day. It was concluded that ethylene did not show positive influence on capsaicin since, individually, SA inhibited ethylene production and MeJA enhanced it. However, both the treatments resulted in elicitation of capsaicin production.
