The effect of specific gravity separation on germination and enzyme activity of Casuarina equisetifolia seeds

Abstract

An attempt was made to separate the seeds based on the weight of the individual seed by using the specific gravity separator. Seed germinaton recorded by A grade seeds was significantly higher than B, C grades and ungraded bulk seeds. D and E grades did not germinate at all. The superiority of A grade seeds was also observed in enzyme activity viz. amylase, catalase, peroxidase and superoxide dismutase explained the increased seed and seedling vigour in the A grade seeds.

Keywords: Casuarina equisetifolia, Seed quality, Specific gravity grading, Enzyme activity, Germination.
