The influence of lead on growth and development of seeds and seed growth of vegetable pea

The objective of the research was to study the influence of lead on seed germination and biochemical composition of seedlings (carbohydrates, chlorophyll, phenolic compounds) of vegetable pea of the variety Ovoshchnoy 76. The problem of the relationship between the soil and plants, including agricultural crops, with heavy metals in the environment, including Siberia region is relevant. Various agricultural plants differ in the specificity of heavy metals accumulation. Their highest content was found in leafy vegetables, and the least in cereals, legumes, industrial crops. Among leguminous crops, peas and beans are the most resistant to lead compounds penetration. At the assessment of the effect of lead on the growth and development of seeds and vegetable pea seedlings, morphometric and biochemical indicators of seeds and seedlings of seed vegetable pea were studied. Morphometric indicators (energy of germination and viability) in laboratory experiment showed the decrease in the percentage of germination of seeds at the research of energy of germination by 1...
