Yield components as indicators of drought tolerance of sugarcane

Abstract: Water deficit is one of the major factors limiting the production of sugarcane (Saccharum officinarum L.). A study of the effects of limited water condition on yield components and their relationship with productivity can aid breeding programs in selecting for high yielding genotypes under this condition. The objective of this study was to investigate the relationships among the parameters stalk number, stalk height, stalk diameter, and stalk weight with cane yield in sugarcane growing in a field under moderat… Show more

“…In fact, SILVA et al (2008) found a positive correlation between these variables and productivity, showing that the increase in these two variables caused by the ideal supply of water directly influenced the production of stalks. It was found that there was no statistically significant difference in the evaluated technological parameters, demonstrating that the system of subsurface drip-irrigation did not alter the quality of sugarcane.…”

“…Silva et al (2008) relataram que maior produtividade de canade-açúcar foi observada para a cultivar que manteve maiores atributos biométricos, tais como número massa e altura de colmos sob condições de estresse hídrico provocado por seca. Ainda a falta de água reduz a quantidade e a razão da fluorescência (Fv/Fm) da clorofila e o conteúdo relativo de água nas folhas, variáveis correlacionadas com produtividade (Silva et al, 2007).…”
