Abstract
Our purpose is to understand some aspects of sucrose yield by addressing physiological, morphological and anatomical traits. This strategy will increase the subjacent knowledge about sucrose yield and let us to a more complex scenario about this important agricultural theme. In fact, improvement in the understanding of ecophysiological aspects related to phytomass production and sucrose yield of sugarcane is an essential condition to the development of the Brazilian sugar-ethanol sector. However, little is known about the relationship between plant traits and sucrose yield in the Brazilian sugarcane genotypes, an important issue for sugarcane breeding programs and modeling. The following questions are relevant for the Brazilian agriculture, mainly considering that sugarcane breeding programs have periodically launched many productive cultivars: why do sugarcane genotypes accumulate differential sucrose amount in stalks? Is it a physiological and/or morphological and/or anatomical matter? Is it related to the source, sink or source-sink characteristics? Is the high sucrose yield related to differential sensitivity of sugarcane genotypes to stressful conditions found during the winter season? Is the differential sensitivity found in a specific phenological stage or in entire crop cycle? About those questions, an integrated approach for studying sugarcane plants is essential to study plant growth and sucrose accumulation. This challenge will be addressed in sugarcane genotypes with differential sucrose yield and canopy architecture growing under field and controlled (greenhouse and growth chamber) conditions. Several physiological, morphological and anatomical traits related to photosynthesis and sugar metabolism will be evaluated, with this project being the first step towards an integrative and interdisciplinary approach to understand the ecophysiology of Brazilian sugarcane genotypes. A team of experts from several well-recognized Brazilian institutions is prepared to deal with biomass production and sugar yield under a holistic point of view. (AU)
