RELATION BETWEEN LEAF AREA AND LEAF RELATIVE WATER CONTENT UNDER THE EFFECT OF DIFFERENT BORON CONCENTRATIONS.

The relative water content in leaf tissues is generally measured to assess the water status of plants while measurement of leaf area is most important for physiological and agronomical studies of crop growth. In the present investigation the effect of different boron concentrations on measurement of leaf area, leaf area ratio and relative water content of leaf tissues of sweet Sorghum c. v. Madhura was studied. The different concentrations of boron used as 10 ppm, 50 ppm and 100 ppm along with control i.e. 0 ppm as distilled water. The leaf area and leaf area ratio are showing increase due to 50 ppm boron concentration which ultimately increases relative water content. However further increase in boron concentration reduces both leaf area and relative water content in c. v. Madhura.
