Germination And Growth

Heavy metal pollution is a major environmental stress than can affect plant growth. The toxic effects of nickel on germination and growth of Coriander (Coriandrum sativum) seedling were investigated for 8 days. Growth of seedling parts especially radicle was greatly reduced for concentration at and above 50 mg/l

The chapter covers various issues related to heavy metals. Here we attempt to document the possible definitions for heavy metals. Heavy metals, the elements having density higher than 3.5 g/cm2 are being added at high rate to our close vicinity. These metals lead to serious problems related to ecology and mankind. Toxic effects of heavy metals are dependent on the concentration of metals, reactivity of metal species and duration of exposure. There is a need to address the toxicological and remedial aspects of heavy metals.

The issue of heavy metal pollution is very much concerned because of their toxicity for plant, animal and human being and their lack of biodegradability. The present study aimed to determine the effects of various concentrations of Ni on seed germination of Pisum sativum. The maximum seed germination was observed at 50 mg/l of Ni for Pisum sativum.

The aim of this paper was the application of statistical analysis including principal component analysis to evaluate heavy metal pollution obtained by moss technique in the air of Ha Noi and its surrounding areas and to evaluate potential pollution sources. The concentrations of 33 heavy metal elements in 27 samples of Barbula Indica moss in the investigated region collected in December of 2016 in the investigated area have been examined using multivariate statistical analysis. Five factors explaining 80% of the total variance were identified and their potential sources have been discussed.
