Ecophysiological behavior sugar cane (Saccharum officinarum L.) and an analysis of scaling up

Abstract

Brazil became the main country producing from sugar cane, an alternative fuel to oil. But several factors interfere with the production of this crop, from soil, climate, management and even the variety. This work aims to quantify and model the water balance of a portion of the culture of cane sugar. Knowledge of water flows is essential for defining the mechanisms of water transfer within a hydrological context. Thus, we intend to perform a monitoring of the main flow of water through the installation of an experimental device, which will provide measurements of: rainfall, interception of precipitation on vegetation, transpiration, water potential, development and ecophysiological function of culture cane sugar, proposing the change of scale from leaf to plant and extrapolating to the hydrographic basin. The information generated by the work will help to establish the water balance and the development of a hydrologic model to one installment. This model could be used for the simulation of water flows in watersheds of the sugar cane regions, especially for the region of Piracicaba river basin. (AU)
