“…Ni-induced improvements in seed germination and early growth in rice mimics its stimulatory effects (Das and Kar et al, 1978;Mishra and Kar, 1974). Furthermore, low concentration of Ni 2+ can promote the activities of peroxidase and ascorbic acid oxidase in alfalfa leaves and can enhance the disease resistance in crops (Theisen and Blincoe, 1984), nonetheless, the promotive effects of Ni 2+ in high plants still needs further investigation. Present study investigated the effects of exogenous application of Ni 2+ at lower concentrations on the physio-biochemical attributes and early growth of rice seedlings with the hypothesis that Ni 2+ being a trace element could improve the early growth of rice if applied at low concentration.…”

High Ni 2+ levels are toxic to plant growth; however, being a micro-nutrient, its application and/or presence in low concentration may improve plant growth. Present study investigated the effects of exogenous Ni application on morpho-physiological attributes of two rice cultivars in China i.e., Yuxiangyouzhan and Meixiangzhan 2. Nickel was applied exogenously to 11 days old seedlings as Ni(NO3)2 in a solution form in the following concentrations: 0.1 mM (Ni1), 0.2 mM (Ni2) and 0.5 mM (Ni3). The seedlings without Ni 2+ application were taken as control. Results showed that exogenous Ni 2+ application improved the early growth of seedlings in terms of seedling length, basal diameter, biomass accumulation and seedling index. Substantial improvements were also observed regarding chl a, chl b, total chl contents and carotenoids in plants under Ni 2+ application compared to CK. Furthermore, all Ni 2+ treatments decreased the content of Malondialdehyde (MDA). Among all applied concentrations, Ni2 proved better regarding its promotive effects, however further research is needed to explore the molecular basis of Ni-induced modulations in seedlings of both rice cultivars.

The essential trace element, nickel, is readily taken up by plants. The biochemical properties of the nickel complex in intrinsically labeled potato and alfalfa were compared and contrasted to ionic nickel. Potato and alfalfa exhibit a similar in vivo nickel complex. The approximate mol wt is 2200-2400 daltons. The complex has a lower polarity than does ionic nickel. The majority of the complex is a cationic species with a minor anionic species. This is confirmed with electrophoresis, ion exchange chromatography and the two nickel complexes' affinity for cationic and anionic resins. Protein does not appear to be associated with either complex.
