Abstract

Flowering phenology in the 4 year-old of Acacia auriculiformis and Acacia mangium plot in tin tailing area located in FRIM sub-station Bidor Perak was observed. The flowering intensity of 22 trees per species was recorded weekly between May 2003 and April 2004. A. auriculifonnis flowered continuously throughout the 12 month observations while A. mangium flowered only in certain months. The peak of flowering seasons for A. auriculifonnis are in July 2003 and January 2004 while only one peak flowering season was observed in A. mangium that is in January 2004. Both species flowered synchronously in January 2004. The relationship of flowering intensity and natural microclimate was analyzed. Generally there is no significant correlation between microclimatic condition and flowering intensity of A. auriculifonnis. Maximum and minimum temperatures found to give moderate microclimate model explained 53 of variation in flowering intensity ofA. mangium.
