“…Flooding affects soils by altering soil structure, depleting O 2 , accumulating CO 2 , inducing anaerobic decomposition of organic matter, and reducing solubility of iron and PHYSIOLOGY OF CITRUS FRUITING manganese (Kozlowski, 1997;Liao and Lin, 2001;Jackson and Colmer, 2005). Most soils suitable for growing citrus become reduced within a few days of flooding (Syvertsen et al, 1983;Davis and Albrigo, 1994). For example, sulfides are reduced to hydrogen sulfide by sulfur-fixing bacteria and this conversion is rather damaging to citrus roots in view of their high sensitivity to hydrogen sulfide.…”

“…In the shoot, flooding reduces stomatal conductance and net CO 2 assimilation, leading to photosynthesis inhibition, altered production and transport of carbohydrates (Phung and Knipling, 1976) and oxidative damages (Gómez-Cadenas, unpublished results). Reduced transpiration impairs hydraulic root conductivity, and hence water uptake (Syvertsen et al, 1983;Vu and Yelenosky, 1991;Pezeshki et al, 1996). In addition, waterlogged soils are very propitious to the proliferation of soil-borne fungi such as Phytophtora.…”

“…Durante o período experimental, a temperatura do solo variou entre 18,7 e 27,5°C, a 40 cm de profundidade (em julho e fevereiro, respectivamente), e entre 11,9 e 21,8°C, a 5 cm de profundidade (em julho e janeiro, respectivamente) (Figura 1B). De fato, temperaturas do solo abaixo de 15°C reduzem a absorção de água pelas raízes dos citros Syvertsen, 1982;Syvertsen et al, 1983), induzindo a menores valores de Ψ f .…”

“…À medida que a planta perde água para a atmosfera via transpiração, vai ocorrendo aumento na tensão da coluna de água no interior dos vasos de xilema. Essa variação diurna de Ψ f ocorre mesmo em plantas com boa disponibilidade hídrica no solo e, em média, esses valores de Ψ f , em laranjeira 'Valência', variam entre -0,4 e -2,4 MPa ao longo do dia (Syvertsen & Albrigo, 1980;Ribeiro, 2006).…”

“…A number of studies have shown increased root resistance to water entry to meet transpirational needs [91][92][93][94]. This may be the result of loss of root hairs or microrrhiza as hypoxia persists, or changes in membrane properties reducing the hydraulic conductivity of roots.…”
