“…bras., Brasília, v.43, n.11, p. 1441-1448, nov. 2008 A longer R1-R4 phase may increase the number of days in which plants are exposed to high temperatures, which may cause spikelet sterility. An exposure to 35 o C, during anthesis, can cause 20-30% sterility (Horie, 1993;Matsui et al, 1997). In the scenarios used in the present study, maximum temperature during the 100 years was equal to or greater that 35 o C in 4, 7, 11, 15, and 21% of the days in scenarios 1a, 2a, 3a, 4a, and 5a, respectively, and 4, 6, 8, 11, and 15% in scenarios 1b, 2b, 3b, 4b, and 5b, respectively, compared to only 2% in the non-climate change scenario (current climate).…”

“…The State of Rio Grande do Sul is the largest Brazilian rice producer, with an average yield of 6.7 Mg ha -1 , in about one million hectares of flood-irrigated fields (Instituto Rio Grandense do Arroz, 2007). Red rice (Oryza sativa L.) is one of the top weeds and it has caused considerable yield reduction in paddy rice fields worldwide (Noldin et al, 1999;Marchezan et al, 2004).…”

-The objective of this study was to assess the development response of cultivated rice and red rice to different increases in minimum and maximum daily air temperatures, in Santa Maria, Rio Grande do Sul State, Brazil. One hundred years climate scenarios of temperatures 0, +1, +2, +3, +4, and +5 o C, with symmetric and asymmetric increases in minimum and maximum daily air temperatures were created, using the LARS-WG Weather Generator, and a 1969-2003 database. Nine cultivated rice genotypes (IRGA 421, IRGA 416, IRGA 417, IRGA 420, BRS 7 TAIM, BR-IRGA 409, EPAGRI 109, EEA 406 and a hybrid), and two red rice biotypes (awned black hull-ABHRR, and awned yellow hull-AYHRR) were used. The dates of panicle differentiation (R1), anthesis (R4), and all grains with brown hulls (R9) were estimated with a nonlinear simulation model. Overall, the duration of the emergence-R1 phase decreased, whereas the duration of the R1-R4 and R4-R9 phases most often increased, as temperature increased in the climate change scenarios. The simulated rice development response to elevated temperature was not the same, when the increase in minimum and maximum temperature was symmetric or asymmetric.Index terms: Oryza sativa, global warming, phenology, simulation, weeds. Impacto do aumento na temperatura média do ar sobre o desenvolvimento do arroz e do arroz-vermelhoResumo -O objetivo deste trabalho foi avaliar a resposta do desenvolvimento do arroz cultivado e do arroz vermelho a diferentes aumentos nas temperaturas mínima e máxima diárias do ar, em Santa Maria, RS, Brasil. Foram criados cenários climáticos de cem anos de 0, +1, +2, +3, +4 e +5 o C, com aumentos simétricos e assimétricos nas temperaturas mínima e máxima diária do ar, usando o Weather Generator LARS-WG e uma base de dados de 1969-2003. Foram usados nove genótipos de arroz cultivado (IRGA 421, IRGA 416, IRGA 417, IRGA 420, BRS 7 TAIM, BR-IRGA 409, EPAGRI 109, um híbrido e EEA 406) e dois biótipos de arroz-vermelho (casca preta aristado e casca amarela aristado). A data da diferenciação da panícula (R1), a antese (R4) e todos os grãos com casca marrom (R9) foram estimados com um modelo não linear. Em geral, a duração da fase emergência-R1 diminuiu, enquanto a duração das fases R1-R4 e R4-R9 aumentaram, com o aumento da temperatura nos cenários de mudança climática. A resposta simulada do desenvolvimento do arroz à elevação da temperatura não foi a mesma, quando o aumento na temperatura mínima e máxima foi simétrico ou assimétrico.Termos para indexação: Oryza sativa, aquecimento global, fenologia, simulação, planta daninha.

“…Decreasing transpiration rates from panicle under elevated [CO 2 ] could increase temperature on the panicle, resulting in increased sterility (Matsui et al, 1997). In addition, Sumida and Ohyama (1990) found that silica uptake by rice plants increased with the increased temperature.…”

“…In japonica rice, the critical temperatures to induce 50% sterility were estimated to be about from 36.5 to 38.5°C [2]. The effect of high temperature on spikelet sterility is found to be exacerbated under high humidity [7].…”

“…Rice pollen sterility induced by high temperatures is exacerbated under increased CO 2 concentrations [7], suggesting a further future threat of rice yield constraints given the simultaneous increases of both air temperature and CO 2 concentrations. Matsui et al [7] suggested that high CO 2 concentrations induce stomatal closure, which leads to reduced transpirational cooling thereby causing plants to be more vulnerable to heat stress.…”

Physiological studies have provided clear evidence of heat-induced spikelet sterility in rice, which can cause significant yield reductions. However, it is rather difficult to evaluate such yield losses in real world situations in farmers' fields, especially across large areas. State-of-the-art technologies, such as remote sensing and crop modeling, can offer solutions for evaluating the heat-induced yield penalty in rice across a spatial area. Remotesensing technologies, especially Synthetic Aperture Radar (SAR), can provide spatial detection of the start of the rice-growing season. This information, combined with time-series temperature data, can be assimilated into a crop simulation model, which can provide a thorough assessment of any heat-induced yield penalty over a specific geographic region. In this paper, we demonstrate how SAR can be used to assess the effects of heat stress in rice in two districts of Andhra Pradesh, India, during the 2017 rabi (dry) season. The accumulated data suggest that 53,623 and 21,436 ha of rice fields in Nellore and West Godavari districts, respectively, had yield losses due to heat stress. Rice fields in Nellore suffered higher yield and production losses due to heat stress because of steeper trend of increasing temperatures during the rice plants' reproductive stage.
