Effects of aluminum toxicity on plant height, total chlorophyll (Chl a+b), potassium and calcium contents in spinach (Spinacia oleracea L.)
Journal Title: International Journal of Farming and Allied Sciences - Year 2016, Vol 5, Issue 2
Abstract
Toxicity of heavy metals such as aluminum and their accumulations in the food chain is one of the main environmental issues in agriculture and natural ecosystems. Aluminum is one of the most important factors limiting plant growth and reduces the efficiency of agricultural production in acid soils. Effects of the aluminum chloride (AlCl3) were studied on morphological and physiological traits in spinach (Spinacia oleracea L. var. Viroflay). For this purpose, attributes that contains plant height (root and shoot), total chlorophyll (Chl a+b) and concentrations of potassium and calcium were studied in a greenhouse. The aluminum toxicity reduced the plant growth, total chlorophyll and calcium concentrations drastically. In the presence of the aluminum, the potassium concentration increased. Due to a significant reduction in plant growth and Ca absorption which is associated with increased concentrations of aluminum, it can be concluded that Viroflay variety of spinach is not resistant to aluminum toxicity.
