Abstract: Water deficit is one of the most important abiotic stress limiting upland rice yield in the "Cerrado" region of Brazil. Selecting drought tolerant cultivars is an important strategy to overcome this constraint. Two greenhouse experiments were conducted at Santo Antônio de Goiás, state of Goiás, Brazil, to compare the response of normalized transpiration rate (NTR) of three modern (BRS Primavera, BRSMG Curinga and BRS Soberana) and one traditional (Douradão) upland rice cultivars to soil water deficit during th… Show more

“…This information will help scientists choose genotypes that are more tolerant to hydric deficiency for breeding (HEINEMANN;STONE;FAGERA, 2011). The reported work aimed to evaluate the effects of Si supply on leaf concentrations of Si, proline content and peroxidase activity in upland rice cultivars grown either with or without exposure to soil water deficits.…”

“…According to Bouman et al (2007), irrigated lowland rice receives approximately 24 to 30% of the freshwater consumed worldwide, and these rice systems are threatened because of the increasing demand for freshwater by humans, industry, and animals. Therefore, the development of technologies that conserve water, such as growing rice under aerobic conditions in a no-tillage system (NTS) instead of flooding , would augment and stabilize upland rice yields in addition to consuming less water (Crusciol, Soratto, & Mateus, 2006;Heinemann, Stone, & Fageria, 2011).…”

“…Moreover, relative transpiration in NSG19 (0.35) and IR20 (0.48) quite differ when plants are subjected to water deficit (PEG-induced -0.5 MPa) for 6 days (Cabuslay et al, 2002). The normalized transpiration rate (NTR) in three modern rice, BRS Primavera, BRSMG Curinga and BRS Soberana and one traditional rice, Douradão has been investigated as indicator in plant responses to the fraction of transpirable soil water (FTSW), which is identified the p factor (at 0.95 NTR) as the adaptability of rice genotypes to drought prone environments (Heinemann et al, 2011). In previous publications, the plant morphological characters i.e.…”
