A Petridish and hydroponic culture experiments were conducted at Crop Physiology Laboratory, Department of Crop Botany, Growth Chamber and Agriculture Chemistry Laboratory, Bangladesh Agricultural University, Mymensingh, during the period from August to October 2011 to investigate the effect of aluminium on morphological characters and growth of wheat seedlings and status of minerals in roots and shoots. The experiment comprised two levels of aluminium concentrations viz., 0 μM (control) and 100 μM and five varieties viz; Kanchan, Shatabdi, Sourav, Bijoy (BARI-23) and Sufi (BARI-22). The experiment was laid out in two factors completely randomized design with three replications. Applications of 100 μM aluminium had a profound influence on hypocotyls and epicotyls length, germination percentages, and roots hoot length and fresh and dry mass production in wheat. The results obtained indicate that germination percentage, hypocotyls and epicotyls length, root and shoot length, leaf length, leaf sheath length, plant height, fresh and dry mass plant were greater in the control than in aluminium stress conditions. This shows that wheat seedlings are susceptible to aluminium. However, among the studied varieties, the reduction of dry mass under aluminium stress was minimum in Shatabdi followed by Kanchan which indicates that Shatabdi was more tolerant to aluminium stress than the other varieties. Aluminium stress severely affected the uptake of essential nutrients especially in the sensitive varieties and tolerant varieties have the self-ability to uptake more nutrients even under aluminium stress condition.
