TOLERANCE AND TOXICITY LEVELS OF BORON IN MUNG BEAN (VIGNA RADIATA (L.) WILCZEK) CULTIVARS AT EARLY GROWTH STAGES
Abstract
Boron (B) toxicity has been recognized as a serious problem in arid and semi arid regions of the world. This study was aimed to determine critical levels of B by studying phenotypic variation for B-tolerance/ toxicity at the germination and seedling stage in three mung bean (Vigna radiata) cultivars; M-6, M-8 & 96009. Boron levels ranging from 0-20 ppm were applied using Boric acid. Germination, growth and photosynthetic attributes were significantly (p<0.001) influenced by varying B levels. However, the cultivars were significantly invariable for germination, seedling height and leaf number. B levels (5-10 ppm) appeared to be nutritionally critical whereas
