Comparative analysis of plant functional traits between invasive (Prosopis juliflora) and native (Acacia nilotica) species.
The interaction of invasive species with native species are often been discussed but sparse data has been available on comparative studies of invasive species with native dominant species. In this study, we compare different plant functional traits of invasive tree Prosopis juliflora (Sw.) DC. and dominant native tree Acacia nilotica (L.) Willd. ex Delile, because better plant functional traits mean better adaptability and invasiveness of a particular alien species. Both P. juliflora and A. nilotica are from the same family 'Fabaceae' and occupy the similar habitat. Most of the leaf traits including leaf chlorophyll content and leaf span are significantly higher for P. juliflora than A. nilotica. Prosopis juliflora also performs much better as compared to A. nilotica in terms of growth rate parameters such as root length and shoot length. Leaf nutrient content is also better in P. juliflora, which means better nutrient uptake capacity as compared to A. nilotica. The present study clearly inflicts that P. juliflora possesses better functional traits than A. nilotica.
