Effect of lead and salicylic acid on some plant growth parameters in Pisum sativum L

Abstract

Lead is a ubiquitous pollutant in the environment widely distributed in soil and waters. Lead-polluted soils may be the major reason for reduction of agricultural products. Therefore, search of compounds with antitoxic properties seems a very actual task. This study was performed to investigate the possible antitoxic effect of salicylic acid using plants of pea (Pisum sativum L.) as experimental objects. It was detected that salicylic acid displayed selective action on plant growth parameters in pea. The possible explanations for the observed phenomena were presented. © IDOSI Publications, 2012.
