Abstract

The present experiment was undertaken to examine whether shading affects the critical boron (B) concentration for leaf blade elongation in black gram. Six days after germination (D6), black gram seedlings were transferred to 8 pairs of pots containing basal nutrient solution: one pot of each pair contained 1 uM H3BO3 and the other 10 uM H3BO3. On D10, one day after the emergence of the first trifoliolate leaf blade (TF1) and one day before the emergence of TF2, four pairs of pots were shaded, decreasing the light intensity they received in the glasshouse to about 35% of full sunlight compared with 70% received by the unshaded plants. The response to B supply of dry matter (DM) and elongation rate (LBER) of TF2 were less pronounced in shaded than in unshaded plants. Critical B concentrations for LBER in TF2 of black gram were 10 mg B kg-1DM in shaded and 15 mg B unshaded plants, suggesting that shading may have decreased the B requirement for LBER. Thus the present results suggest that light may need to be considered when setting critical values for the diagnosis of B deficiency in black gram.
