Inoculation of Trichoderma asperelloides ameliorates aluminum stress-induced damages by improving growth, photosynthetic pigments and organic solutes in maize.

ABSTRACT: Excess aluminum (Al) is a stressful condition that affects plant growth and yield quality. This study evaluates growth responses and changes in the contents of photosynthetic pigments and organic solute in maize (Zea mays L.) plants inoculated with Trichoderma asperelloides isolates (T01, T02, T74, T76, or T96) and treated with increasing doses of Al (0, 50, 100, 150, and 200 µM of Al). Uninoculated unstressed plants served as control. Absolute growth rate, root length, dry biomass (shoot, roots and total) and shoot:root ratio were significantly affected in Al-stressed maize plants inoculated with T. asperelloides. Also, chlorophylls (a, b and total) were significantly reduced, whereas carotenoids and anthocyanins increased in those plants. Except for car
