Abstract

Concentration of 5, 10, 20, 80, 320 and 1280 p.p.m. of 1,2-dibromo-3-chloropropane (DBCP) were applied to banana plants growing in a vermiculite medium supplied with a nutrient solution. After four weeks, plant heights were significantly increased by concentrations of 10 and 20 p.p.m. DBCP. Compared with controls, internode lengths were significantly higher (P= 0·05) in plants treated with 10 p.p.m. DBCP. Uptake of S in plants was significantly increased by concentrations of 5, 10, 20 and 80 p.p.m. DBCP. The uptake of N, P, K, Ca and Mg were significantly lower (P=0·05) in plants treated with 1280 p.p.m. DBCP.
