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.

In plants, the provided by Ecological-Biological Center of Kazan, toxicant may provoke growth alterations like production Republic of Tatarstan, Russia. The land plot had reduction, yellowing of leaves and disturbing loamy soil and was open to sun. Pea seeds photosynthesis [4]. Besides, it may present serious (Pisum sativum, breed Venetz) was provided by problems for human health [5]. Many methods of Tatar Scientific Research Institute of Agriculture, environmental monitoring of lead pollution were Russian Academy of Agricultural Sciences. In the control suggested [6] and a lot of approaches for lead variant, plants were not treated. There were 3 experimental detoxication were discussed [7, 8]. Among other variants – with lead acetate (Pb(CH COO) - 0.25 mg/L, detoxicants, salicylic acid was stated as potential agent in lead acetate plus salicylic acid (C H (OH)COOH) regulation of plant stress response [9-12]. Moreover, this 10(-4)M and with salicylic acid alone. All variants received compound was showed to be able to alleviate cadmium the same amount of irrigation. During 5 weeks, the toxicity in plants [13]. Thus, the aim of the present study following parameters were monitored -plant height, a was to investigate lead action on some plant growth number of tendrils, a number of leaves, leaf length and characteristics of Pisum sativum and the potential leaf width. For each variant, 50 individual plants were antitoxic effects of salicylic acid that was chosen as analyzed. Experimental data were presented as mean ± antitoxicant to lead. standard error. 3 2 6 4
