Abstract:
The aim of this study was to detect the ability of two maize verities seeds (Hudeiba one and
Hudeiba two) to germinate, grow and remove cadmium element from contaminated soil. In pot
experiment two maize varieties (Hudeiba one and Hudeiba two) seeds were grown in soil spiked
with different levels of cadmium concentration, which were 0, 10, 25, 50, 75 and 100 mg/L.).
Growth parameters and concentration of cadmium in plant tissues was measured. The results
showed that for the two varieties of maize Hudeiba one and Hudeiba two seeds have ability to
germinate and grow under different concentration of cadmium. Also it was found that cadmium
affected the most growth parameters such as leaves area, fresh shoot weight, fresh root weight,
dry root weight and dry shoot weight in all treatments. The results also indicated that the two
varieties of maize (Hudeiba one, Hudeiba two) seedlings and plant, can uptake cadmium element
from contaminated soil with different concentration levels up to 100 mg/kg-1. The results
indicated that low concretion levels of cadmium up to 100mg/L can enhance the germination of
seeds. Statistical analysis of the results showed that the accumulation of cadmium in roots was
greater than in shoots for both seedlings, for the different level of concentrated. In conclusion
maize variety, Hudeiba 1 and Hudeiba 2 seedlings can be used for phytoremediation of cadmium
contaminated soil. |
