Talisia esculenta seed quality in function of drying temperatures and times
Talisia esculenta Radlk is a species of the Sapindaceae family native to the Amazon region. Its fruits are principally obtained by collecting in natura; its propagation is by seeds, which are of the recalcitrant type, with low longevity and sensitivity to dehydration. We evaluated the effects of di...
