The Study Effects of Heavy Metals on Germination Characteristics and Proline Content of Triticale (Triticoseale Wittmack)
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 10
Abstract
In order to study, the effects of copper sulfate, cadmium nitrate and lead nitrate on germination characteristics and proline content of Triticoseale Wittmack an experiment in factorial-laid out complete randomized design with four replications was conducted at Seed Technology Laboratory, Faculty of Agriculture, Mashhad Branch, Islamic Azad University-Mashhad Iran, in 2014. Factors were included of heavy metals in three levels (copper sulfate, cadmium nitrate and lead nitrate) and concentrations in six levels (0, 50, 150, 300, 500, and 1000 ppm). Analysis of variance showed that the effect of heavy metal, concentration and interaction between two factors on all traits were significant at 1% probability. Means comparisons (type of heavy metal × concentration) indicated that cadmium nitrate and copper sulfate with 1000 mg/L-1 concentration, had the highest inhibitory effect on all characteristics. So, measurement of proline content showed that the relation between proline content and heavy metal concentration (in every three metals) was linear, positive and significant. But the most accumulation of proline (3.2 µmol/gdw) observed in 1000 mg/L-1 of cadmium nitrate.
