| dc.description.abstract | In the present study the vegetable seeds viz., Amaranthus, Carrot, Chilli, Onion, Radish and Watermelon were permeated with capsaicinoleoresin via organic solvents and evaluated for their seed quality parameters. High quality seeds responded negatively (10-40% reduction in germination) to the Capsaicin Oleoresin permeation. Among the source of capsaicin oleoresin extracts Capsicum frutescens with high capsaicin was profound negative effect compared to Capsaicin Oleoresin from C. annuum. However, among solvents used for capsaicin oleoresin extraction and permeation acetone recorded highest reduction of seed germination in Amaranthus, Chilli and Onion to extent of 15-40 per cent. While Carrot and Watermelon permeated seeds showed 20-30 per cent reduction in germination compared to that of non permeated dry seeds. Increase in fresh ungerminated seeds (FUS) was evident upon capsaicin oleoresin permeation in all the crops except Radish. The response of other quality parameters were as similar to that of the germination results. While, the chilli seeds subjected to six days of accelerated ageing and then permeated with capsaicin oleoresin through acetone recorded increased germination from 30 to 50 per cent showing the evidence of its antioxidant property. Capsaicin Oleoresin permeated seeds through organic solvents recorded decrease in seed infection percentage with an increase in Capsaicin-Oleoresin concentration in all the crops as a result of its antifungal property. However, these properties of Capsaicin- Oleoresin are better exhibited in chilli seeds and onion was found highly sensitive for Capsaicin-Oleoresin permeation and radish showed no response. | en_US |
