Effect of Lead on Some Phenotypic Characteristics, Protein Changes and Productivity of Beta vulgaris var. cicle
Keywords:lead, amino acids, chard plant, genetic characteristics, phenotypes
This study was conducted at the College of Education for women, Tikrit University / department of biology,
and aims to find out the effect of lead in different concentrations (125, 250 and 500) mg / kg on the phenotypic,
physiological and genetic characteristics (amino acids) of chard Beta vulgaris var. cicle.
The results showed that soil pollution with lead leads to inhibition of vegetative growth through its effect on
the processes of division, cellular expansion and hormonal regulation, as well as negatively affects various
vital activities and different metabolic processes (photosynthesis, respiration, building of nucleic acids,
proteins, enzymatic activities, and other vital activities necessary for plant growth and reduces productivity).
