“…Each stage has its own environmental and physiological needs. Factors that influence the induction of cane flowering include photoperiod (12-012.5 h of light), temperature (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32) C), thermal amplitude (<13 C), latitude (between 10 N and 10 S), and humidity (>60 %), among others [38]. Outside of these conditions, or under adverse conditions, flowering occurs, but often synchrony between male and female lines remains a challenge; therefore, strategies such as sowing at different dates and photoinductive treatments are needed to aid crossbreeding.…”

Sugarcane is the main source for sugar production and the most important crop for energy production, as well as for byproducts like ethanol and fibers in the world. With a complex genome, the plant has its species from crosses between species of the genus Saccharum, which were the basis for sugarcane breeding programs worldwide. The production of sugarcane has increased worldwide due to breeding programs that have developed more productive clones for specific uses and adapted to different climatic conditions. The future objective of breeding programs is to develop sugarcane with high productivity, high sucrose content, drought tolerance, and high production of ethanol and biomass, i.e., plants with high fiber content and with cell walls easily broken to favor the production of ethanol from bagasse, efficient plants with low nitrogen fertilizer use, and others, and consequently to reduce environmental impacts. Currently, the demand for products derived from sugarcane is consistently increasing; the ethanol byproduct has been pointed out as one of the important sources to feed the demand for renewable energy in fossil and nonrenewable fuel substitution programs in different countries around the world. This chapter describes the genetic improvement of sugarcane and its current goals.

“…Houve tendência de aumento dos sólidos solúveis totais ( o Brix) para maiores valores de lâmina de água aplicada, assim como para Pol (%), pureza e ATR (açúcares totais recuperáveis). Quando ocorrem condições favoráveis e a planta atinge uma maturação relativa de desenvolvimento, pode ocorrer o florescimento , que é um fenômeno indesejável em áreas comerciais, devido ao elevado consumo de sacarose e redução do volume de caldo, resultando no aumento do teor de fibras (ARALDI et al, 2010).…”

“…The flowering process occurs simultaneously with the ripening process. Araldi et al (2010) reported that the factors that influence flowering are the sensitivity of the variety to flowering, minimum age of the plant (varieties that are very sensitive to flowering may be induced at six months), photoperiod (optimum is approximately 12.5 hours) and light intensity, temperature (small variations in temperature can cause significant changes in flowering), humidity (humid and cloudy days favor flowering, which is less common in hot, dry regions), altitude (lower altitudes favor flowering), chemical products (various hormonal chemical products decrease flowering, which is of great practical interest) and fertilization (excess nitrogen can hinder or prevent flowering).…”
