Problem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand&#13; soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on&#13; organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand&#13; soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and&#13; 2010 to evaluate the physiological and growth responses of sugarcane to water-deficit stress during&#13; formative growth. Treatments included organic (muck) and sand soils and two water regimes Well&#13; Watered (WW) and Water-Deficit Stress (WS). Sugarcane cultivar CP 80-1743 was planted in pots&#13; and fertilized with N, P and K based on soil analyses. All pots were well watered until 58 days after&#13; planting, when water was withheld from the WS pots. During the WS treatment, plant growth rate, leaf&#13; Relative Water Content (RWC), proline content and photosynthesis components were measured. Final&#13; tillers, Green Leaf Area (GLA) and shoot biomass were determined 27 (in 2009) or 22 (in 2010) days&#13; after initiating the WS treatment. Results: Stress symptoms of sugarcane plants appeared 7-10 days&#13; earlier on sand soil than on muck soil. Water stress reduced stomatal conductance (gs), Photosystem II&#13; Photochemical Efficiency (FPSII), leaf Photosynthesis rate (Pn), the number of tillers and GLA,&#13; resulting in reduced shoot biomass, especially on sand soil. Neither leaf RWC nor proline content was&#13; a sensitive WS indicator. Conclusion: Nondestructive measurements of physiological traits of gs,&#13; FPSII and Pn during the formative stage may be useful for early detection of water stress in sugarcane
