Entropia, informação e estresse hídrico em Eucaliptus camadulensis in vitro

Abstract

The aim of this was to explore a new approach on plant development through the interpretation of their entropic states. The Eucaliptus camadulensis entropic states, in vitro cultivated under water deficit conditions, were evaluated through the dry matter production utilizing the Clausius and Shannon functions. The plants cultivated under water deficit followed the thermodynamic second law like a dissipative structure. Whereas the entropic production increased the leaf tissues diffrentiation decreased, there was a reduction of the plant organization, mainly at the -1.5 MPa osmotic potencial. The ideal thermodynamic efficiency for the analised material was between 0.57% and 0.62%.
