“…These results were found in accordance with already reported findings in literature which state that droughttolerant sugarcane genotypes exhibited high relative water content as compared to the drought-sensitive genotypes [4,2]. For variability parameters studied, RWC at 60 days after planting exhibited low magnitude of PCV and GCV (6.11 and 3.67%) under normal (E1) environment whereas under water stress (E2) environment, a high magnitude of PCV and moderate GCV (20.37 and 11.61%) was recorded, respectively.…”

“…Although derived for sweet corn, the method compared well with sugarcane stomatal diffusion resistances measured under ambient atmospheric [CO 2 ] by Venkataramana et al (1986), Grantz and Meinzer (1990), Souza et al (2008), and Vu and Allen (2009).…”

This study evaluated the effects of climate change on sugarcane yield, water use efficiency, and irrigation needs in southern Brazil, based on downscaled outputs of two general circulation models (PRECIS and CSIRO) and a sugarcane growth model. For three harvest cycles every year, the DSSAT/CANEGRO model was used to simulate the baseline and four future climate scenarios for stalk yield for the 2050s. The model was calibrated for the main cultivar currently grown in Brazil based on five field experiments under several soil and climate conditions. The sensitivity of simulated stalk fresh mass (SFM) to air temperature, CO 2 concentration [CO 2 ] and rainfall was also analyzed. Simulated SFM responses to [CO 2 ], air temperature and rainfall variations were consistent with the literature. There were increases in simulated SFM and water usage efficiency (WUE) for all scenarios. On average, for the current sugarcane area in the State of São Paulo, SFM would increase 24 % and WUE 34 % for rainfed sugarcane. The WUE rise is relevant because of the current concern about water supply in southern Brazil. Considering the current technological improvement rate, projected yields for 2050 ranged from 96 to 129 tha −1 , which are respectively 15 and 59 % higher than the current state average yield.Climatic Change (2013) 117:227-239 DOI 10.1007/s10584-012-0561-

“…Drought is one of the most important environmental stress factors limiting sugarcane production worldwide (Venkataramana et al, 1986). Water-deficit stress alters a variety of growth and physiological processes in sugarcane, which cause decreased yields (Zhang et al, 2001;Silva et al, 2007).…”

Problem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and 2010 to evaluate the physiological and growth responses of sugarcane to water-deficit stress during formative growth. Treatments included organic (muck) and sand soils and two water regimes Well Watered (WW) and Water-Deficit Stress (WS). Sugarcane cultivar CP 80-1743 was planted in pots and fertilized with N, P and K based on soil analyses. All pots were well watered until 58 days after planting, when water was withheld from the WS pots. During the WS treatment, plant growth rate, leaf Relative Water Content (RWC), proline content and photosynthesis components were measured. Final tillers, Green Leaf Area (GLA) and shoot biomass were determined 27 (in 2009) or 22 (in 2010) days after initiating the WS treatment. Results: Stress symptoms of sugarcane plants appeared 7-10 days earlier on sand soil than on muck soil. Water stress reduced stomatal conductance (gs), Photosystem II Photochemical Efficiency (ΦPSII), leaf Photosynthesis rate (Pn), the number of tillers and GLA, resulting in reduced shoot biomass, especially on sand soil. Neither leaf RWC nor proline content was a sensitive WS indicator. Conclusion: Nondestructive measurements of physiological traits of gs, ΦPSII and Pn during the formative stage may be useful for early detection of water stress in sugarcane.
