Ang L. H., . and Mullins C., . and Maruyama Y., . and Seal W. E., . (2000) Effects of irradiance and atmospheric drought on phyllode temperature of Acacia mangium and Acacia auriculiformis grown on sand tailings. [Proceedings Paper]
Abstract
Two acacias were planted on sand tailings situated at about 8 m above standing water table level. The water supply to the study site was mainly rain fed. The air temperature irradiance and phyllode temperature of both acacias were quantified with appropriate sensors logged on datatakers. The results showed that phyllode temperature of Acacia mangium normally was higher than Acacia auriculiformis and exceeded the critical leaf temperature 40C for a duration than 30 minutes in midday. The study indicates that the high phyllode temperature of both species was due to atmospheric drought and could be very severe especially for Acacia mangium if a mild drought occurred. Both acacias grown on the study site would suffer heat stress after a continuous six dry days.
