Abstract

The mutual effects of boron (B) and zinc (Zn) on growth, total chlorophyll (Chl), membrane permeability (MP), and nutrient content were investigated in peanut (Arachis hypogaea L.). The soil was treated with five levels of B (0, 4, 8, 16, 32mgkg(-1)) and three levels of Zn (0, 10, 20mgkg(-1)). Plant growth was progressively depressed with increasing of B. However, Zn addition had an inhibitory effect on B toxicity and decreased growth reduction caused by excess B. In Zn-untreated plants, B and Zn contents were enhanced by increasing of B; moreover, both Zn and B addition enhanced Zn content. The Chl content decreased and MP increased, resulting from B toxicity; however, Zn addition partially ameliorated the adverse effects of B toxicity on Chl and MP. Increasing B enhanced phosphorus (P), potassium (K), calcium (Ca), iron (Fe), Zn, copper (Cu), and sodium (Na) contents in peanut shoots.
