“…The closing of the stomata is one of the most prominent responses to flooding, leading to a decrease in gas exchange (Nicolás et al, 2005) and consequently to a decrease in photosynthesis and in stoma conductance. However, an optimization promoted by an increase in the number of stomata can favor a greater intake of carbon dioxide gas, which diminishes the stomata resistance and facilitates the carbon assimilation process (Henrique et al, 2010). This probably occurred in the 'Saracura' maize, because there was an increase in the stomata number, both by area and by number of epidermis cells in the last selection cycles, which might benefit the gas exchange.…”

“…Resultados semelhantes foram obtidos por Henrique et al (2009) nos quais, plantas de Caesalpinia peltophoroides Benth. (Caesalpinioideae), submetidas ao alagamento total, apresentaram efeito negativo no crescimento, com uma queda de aproximadamente 41% na produção de biomassa seca aos 25 dias após a indução do estresse.…”

“…Embora as condições sob as águas sejam desfavoráveis no que diz respeito à disponibilidade de luz e CO 2 , em algumas espécies, a fotossíntese subaquática pode aumentar a concentração de O 2 interno e o teor de carboidratos, resultando em continuação da respiração aeróbia (MOMMER;VISSER, 2005). Reduções nos teores de carboidratos em folhas e raízes também foram observadas em plantas de Potamogeton pectinatus (DIXON et al, 2006); em Caesalpinia peltophoroides (HENRIQUE et al, 2009) e em Sesbania virgata (ZANANDREA et al, 2010), quando totalmente submersas em água. Quando as plantas são sujeitas a imersão parcial também há privação do O 2 no seu sistema radicular, levando a fermentação alcoólica, cuja eficiência para produção de energia (ATP) é baixa.…”

“…Cell-wall ingrowths or phi-thickening have been reported in loquat (Eriobotrya japonica Lindl.) root [11], apple (Pyrus malus) [12], geranium (Pelargonium hortorum) roots [12] Sibipiruna (Caesalpinia peltophoroides) [13] with solute movement (salt stress) [12], water logging [13], and drought stress [11]. Although the effect of early season drought on ingrowths and phi-thickenings has not been investigated in peanut and further investigations are necessary to understand phi-thickenings.…”
