Yulianti, Sudrajat DJ. 2016. Morphological responses, sensitivity and tolerance indices of four tropical trees species to drought and waterlogging. Biodiversitas 17: 110-115. Indonesia’s climate model predicts an increase in threat of drought and waterlogging in several areas. However, knowledge on variations between tropical forest tree species, i.e. Anthocephalus macrophyllus, Anthocephalus cadamba, Fragrea fragrans, and Magnolia champaca to drought and waterlogging stress are still limited, though they are relevant to future development of forest ecosystem. The objective of this research is to investigate the adaptability of four potential tree species to drought and waterlogging stress in a controlled greenhouse. The results showed that the adaptive responses of four tropical tree species were different, according to the results, all species were more tolerant to waterlogging than to drought stress, which can be observed from morphological, seedling survival, stress tolerant and stress sensitivity indices. The waterlogging resistant in four species followed the order of: A. cadamba > F. fragrans > A. macrophyllus, and > M. champaca, while for the drought resistant species followed the order: A. macrophyllus > A. Cadamba > F. fragrans and > M. champaca. © Biodiversitas, 2012. All Rights Reserved.
