PHYSICAL AND BIOCHEMICAL ANALYSIS OF SODIUM AZIDE TREATED SORGHUM BICOLOR (L.) MONECH

Abstract

The present work was carried out to check the effect of different concentrations of Sodium
azide (0.5% and 1%) on the seeds of Sorghum. Germination rate, shoot length, root length, fresh
weight, dry weight, plant height at maturity, total and reducing sugar, total protein and chlorophyll
contents were checked from control as well as 0.5% and 1% sodium azide treated M1 plants.
The higher germination rate, root length, fresh weight, dry weight were observed in control
plants. It was also observed that in control plants total sugar and chlorophyll contents were high.
The higher shoot length, plant height at maturity, reducing sugar contents, total proteins contents
were observed in 1% sodium azide treated plants. It is concluded from these results that 0.5%
sodium azide treatment for sorghum is not suitable for plant growth but 1% sodium azide treatment
showed some effects on morphological and physiological characters of sorghum plant.
