Shea Tree

Vitellaria paradoxa, commonly known as the shea tree, is a tree of the family Sapotaceae and represents a traditional African food plant. It has been claimed to have the potential to improve nutrition, boost food supply, foster rural development, and support sustainable land care. Despite its multiple potentials, statistical data relating to its production are non-existent and/or unexploited in several African communities. To contrast this tendency, the present study aims to assess the intra-seasonal variation in fruit production of a sample of 115 shea trees and then to establish a correlation between yield parameters and several dendrometric features. Dendrometric (i.e. tree height, trunk girth, and crown basal area) and pomological (i.e. fruit and nut length and width) parameters, as well as yield parameters by monitoring daily fallen fruit from each sampled shea tree, carried out for five years consecutively, were considered for this study. The results showed inter-year fluctuation of shea fruit/nut number and shea fruit/nut weight. In addition, the results showed a significant increase in the annual average of shea fruit/nut yield per tree and as well per girth and/or crown basal area interval class, randomly generated by Sturge and Yule's formula. Interestingly, potentially high producing trees emerged within each considered interval class. Then, observed intraclass variation between trees determining shea yield can be exploited in selecting elite shea trees.

The Brazilian cerrado has undergone an intense process of fragmentation, which leads to an increase in the number of remnants exposed to edge effects and associated changes on environmental conditions that may affect the phenology of plants. This study aimed to verify whether the reproductive phenology of Xylopia aromatica (Lam.) Mart. (Annonaceae) differs under different light conditions in a cerrado sensu stricto (a woody savanna) of southeastern Brazil. We compared the reproductive phenology of X. aromatica trees distributed on east and south cardinal faces of the cerrado during monthly observations, from January 2005 to December 2008. The east face had a higher light incidence, higher temperatures and canopy openness in relation to south face. X. aromatica showed seasonal reproduction at both faces of the cerrado, but the percentage of individuals, the synchrony and duration of phenophases were higher at the east face. The study demonstrated the influence of the environmental conditions associated to the cardinal orientation of the cerrado faces on the phenological pattern of X. aromatica. Similar responses may be observed for other species, ultimately affecting patterns of floral visitation and fruit production, which reinforces the importance of considering the cardinal direction in studies of edge effects and fragmentation.
