Shea (Vitellaria paradoxa C.F.Gaertn.) seedlings recovery after fire: gas-exchange, growth and biomass partitioning assessment
ABSTRACT Shea (Vitellaria paradoxa C.F. Gaertn) is native to the savanna ecosystem, an ecosystem prone to periodic bushfires due to the long dry season and accumulated combustible biomass. We studied the effects of simulated fire on shea seedlings gas exchange, growth and biomass allocation in a greenhouse experiment. We hypothesized that fire decreases photosynthetic performance of regrown leaves leading to lower growth and altered biomass allocation in shea seedlings. Sixteen weeks after fire treatment, none of the measured photosynthetic, growth and biomass parameters showed a significant difference between fire treated seedlings and, control seedlings. Shea seedlings have therefore shown exceptional recovery of gas exchange performance, growth and biomass allocation patterns 4 months after fire.
期刊介绍：
Forests, Trees and Livelihoods originated in 1979 under the name of the International Tree Crops Journal and adopted its new name in 2001 in order to reflect its emphasis on the diversity of tree based systems within the field of rural development. It is a peer-reviewed international journal publishing comments, reviews, case studies, research methodologies and research findings and articles on policies in this general field in order to promote discussion, debate and the exchange of information and views in the main subject areas of.
