Effects of Paclobutrazol and Daminozide on the Growth of Acacia mangium Seedlings
Abod, Sheikh Ali and Yasin, Sulaiman (2002) Effects of Paclobutrazol and Daminozide on the Growth of Acacia mangium Seedlings. Pertanika Journal of Tropical Agricultural Science, 25 (2). pp. 143-147. ISSN 0126-6128
Low concentrations of paclobutrazol and daminozide at 0, 5, 10 and 15 mgt] were foliar sprayed on 12 week old A. mangium seedlings at three different frequencies of application i.e. 1 (week 0), 2 (week 0 & 4) and 3 (week 0, 4 & 6). Either chemical was effective in controlling growth but paclobutrazol was more potent than daminozide. A low concentration of 5 mgt] paclobutrazol at 1 application was sufficient to cause a significant reduction in height growth compared to daminozide which required a minimum concentration of 10 mgt] with 2 applications. In general, the main effects of the chemicals increased with increasing concentration and frequency of spray.
