Abstract:

The aim of this study was to investigate the effects of high temperature on seed quality and peroxidase activity. High temperature stress was imposed on four brinjal genotypes at three levels (25 °C, 35 °C and 40 °C). Seeds were allowed to germinate on Petri-plates using two layers of filter paper in hot air oven and seed quality parameters were recorded. As expected, high temperature resulted in decreased seed quality parameters. In germination 100 percent reduction was observed in all the genotypes at severe temperature stress (40 °C), 53 % was recorded at moderate temperature stress (35 °C), whereas in control (25 °C) 88.5 % was recorded. Highest mean germination percentage was recorded in Arka Anand (57.33 %) and lowest was recorded in Arka Shirish (41.25 %). Peroxides activity was high in seedlings exposed to high temperature treatment when compared to control in all the samples. Genotype Arka Anand showed significantly higher activities of peroxidase enzyme in response to high temperature compared to those from the leaves of other genotypes.
