“…Panday and Total sugar content remains unaffected at lower concentration of nickel but reduced at higher level of nickel (Table 3). These results are similar to the finding of Ezhilvannn et al 43 in Arachis hypogaea and Espan et al 44 in radish. Rabie et al 45 reported decrease in carbohydrates with respect to the high levels of nickel in corn and broad bean and suggested that this decline is due to a role of nickel on the enzymatic reactions related to the cycles of carbohydrates catabolism.…”

An attempt was made to study the effect of nickel on the growth of Abrus precatorius, a medicinal plant growing in South Gujarat used in Ayurved. The seeds of Abrus precatorius were germinated in petri dishes by 25, 50, 100, 150, 200 ppm nickel sulphate solution for experimental work. The germination percentage, seedling growth, dry matter yield and changes in biochemical contents of total sugar, protein and pigments were investigated ten days after showing. The study indicates that the lower level of nickel has no adverse effect on germination, seedling growth and biochemical content whereas the higher concentration decreased the same accept the protein. Nickel increased the protein content at lower concentration and has been reducing effect at higher level.

“…Seed germination is sensitive to the nickel status of the environment because this mineral enters in the seeds during imbibition (Larcher 1995) and causes adverse effects on germination and subsequent seedling growth (Espen et al 1997;Gupta et al 2001;Parida et al 2003;Leon et al 2005). The present studies indicate decrease in germination percent as well as loss of seedling vigor when rice seeds are germinated in the presence of 200 or 400 lM Ni 2+ in the medium.…”

When the seeds of two rice cvs. Malviya-36 and Pant-12 were germinated up to 120 h in the presence of 200 and 400 lM NiSO 4 , a significant reduction in the germination of seeds occurred. Seeds germinating in the presence of 400 lM NiSO 4 showed about 12-20% decline in germination percent, about 20-53% decline in lengths and about 8-34% decline in fresh weights of roots and shoots at 120 h of germination. Ni 2+ exposure of germinating seeds resulted in apparent increased levels of RNA, soluble proteins, and free amino acids in endosperms as well as embryo axes. A 400 lM Ni 2+ treatment led to about 58-101% increase in the level of soluble proteins and about 39-107% increase in the level of free amino acids in embryo axes at 96 h of germination. Activities of ribonuclease and protease declined significantly with increasing levels of Ni 2+ treatment. Isoenzyme profile of RNase as revealed by activity staining indicated decline in the intensities of 3-4 preexisting enzyme isoforms in embryo axes of both the rice cultivars and disappearance of one of the two isoforms in endosperms of cv. Pant-12 due to 400 lM Ni 2+ treatment. Results suggest that the presence of high level of Ni 2+ in the medium of germinating rice seeds serves as a stress factor resulting in decreased hydrolysis as well as delayed mobilization of endospermic RNA and protein reserves and causing imbalance in the level of biomolecules like RNA, proteins, and amino acids in growing embryo axes. These events would ultimately contribute to decreased germination of rice seeds in high Ni 2+ containing environment.

“…Nickel, one of the important heavy metal pollutants is of considerable concern because its concentration is rapidly increasing in soils of different parts of the world (Echevarria et al, 1998;Faryal et al, 2007;Atiq-urRehman and Iqbal, 2008). The increasing concentration of Ni 2+ has been shown to inhibit seed germination and seedling growth of different plant species (Espen et al, 1997;Farooqi et al, 2009). Nickel stimulates many enzymatic activities at very low concentration and it found a part of active metallo center of hexamer enzyme urease (Gerendas et al, 1999).…”
