Influence of boron on the morphological and physiological growth parameters of bean

Abstract

Effect of boron on Phaseolus vulgaris L. var. Cacahuate was studied in nutrient solutions containing 0.000; 0.005; 0.050 and 0.500 ppm of the element. The deficiency of boron affected root growth, leaf development and plant growth. Lower values of net assimilation rate (NAR) indicated reduced photosynthetic activity in the case of boron deficiency. No definite conclusions regarding the role of boron could be drawn on the basis of the other morphological or physiological parameters studied.
