Abstract

The effect of alachlor [2-chloro-2′,6′-diethyl-N-(methoxymethyl)acetanilide] and gibberellic acid (GA3) on increase in length of corn (Zea mays L.) epicotyl segments and the interactions between alachlor (0, 5 × 10-6, 5 × 10-4, 4.4 × 10-4, and 5 × 10 M) and GA3 (0, 1 × 10-6, 2.8 × 10-4, and 1 × 10-4 M) were investigated. Alachlor significantly inhibited growth of these segments while GA3 usually increased growth. GA3 in combination with alachlor caused a significant increase in growth compared to alachlor alone resulting in growth comparable to that occurring in untreated tissues. The magnitude of GA3 induced growth in the presence of alachlor depended upon the concentrations of the herbicide and GA3 employed. Alachlor was, however, able to inhibit the GA3 induced growth. The maximum degree of growth inhibition resulted from exposure of the segments to alachlor with or without GA3 from the start of incubation. This inhibition decreased as the exposure to alachlor was delayed. Alachlor started inhibiting growth in the presence of GA3 after the first 9 hr of incubation and after the first 21 hr of incubation in the absence of GA3.
