Mungbean: a nickel indicator, accumulator or excluder?
Seeds of the two mungbean cultivars were exposed to 25, 30, 35 and 40 mg L(-1) nickel along with control. Nickel stress decreased growth, photosynthetic pigments, yield attributes and cation (Na(+), K(+) and Ca(2+)) accumulation in mungbean. This reduction was less at 25 mg L(-1) as compared to 40 mg L(-1) nickel. In addition, nickel was mainly stored in roots and restricted transfer to the aerial parts (shoot and least by leaves) was observed.
