Última The adaptive value of shoot differentiation in deciduous trees and its evolutionary relevance Boletín de la Sociedad Dörken,Veit M.; Stützel,Thomas. Pronounced long shoot/short shoot differentiation is typical for deciduous angiosperm trees. It also occurs in a number of gymnosperms and very few evergreen angiosperm trees. The study of 719 angiosperm tree species (602 deciduous and 117 evergreen species) demonstrated that the deciduous condition is nearly always associated with shoot differentiation. Detailed measurements in 38 angiosperms showed that the leaf area of an entire short shoot equals the leaf area of a single long shoot leaf of the same species and individual. In the few cases where the leaf area of the short shoot is slightly larger than that of a single long-shoot leaf, the short shoot leaves shade each other and the projection of the short shoot equals the area of a single long shoot...
