A Research on Different Ecological Soil Condition on Level of Catalase Enzyme of Corn Plant
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2015, Vol 9, Issue 11
Abstract
To study the effect of different levels of salinity on physiological characteristics and the amount of antioxidant enzyme of corn leaves as an indicator of resistance to salt stress, a study in 2013 in agricultural Research Laboratory of KharazmiUniversity was performed as a factorial experiment and completely randomized with three replications. The experiments consisted of four different levels of salinity ( 35, 46, 19 , 16 dS m). Corn is considered as one of most important crop plants in Iran. And the area under cultivation is 0.25 million hectares and its production is 1.65 million tons. And it allocates the production of 2.8% of all cereal productions. In many areas of agriculture in the world, salinity is considered as one of limiting factors of agricultural production. And it affects 30% of world’s land and in Iran, about 50% of lands under cultivations are faced with the salinity problem. By increasing salinity levels, stomatal conductance, leaf’s relative water content are decreased. Treated samples were trained with system scattering and in perlite medium. The effect of salt stress was observed on the amount of antioxidant enzymes of leaves as meaningful changes. Treated corn shows the highest growth rate compared to other treated samples .with Libyan desert, despite having the highest level of salinity.
