Title: Carbon translocation as affected by shade in saplings of shade tolerant and intolerant species
Author: Souza, RP
Valio, IFM
Abstract: Carbon translocation was affected by shade in different tropical tree species differing in successional status and degree of shade tolerance, Plants of the early-successional shade-intolerant species Cecropia pachystachya and Schizolobium parahyba and of the late-successional shade-tolerant species Myroxylon peruiferum and Hymenaea courbaril were grown under full sun (FS) and natural shade treatments (NS) and assessed for [C-14]-sucrose translocation, Most of the C-14 was retained in the fed leaf after a 24 h translocation period. Under FS, the growing apical part of the plant was the most intense sink for most species, Shade affected growth and sink intensity differently in early and late successional species, Growth was more markedly affected in the early species, Whereas these continued to invest carbon into the growing apical part of the plant under shade conditions, the late successional species invested relatively more into other sinks.
