“…On the other hand, the variable Y h is the simulated yield at a given temperature condition after the maximum temperature exceed the high temperature threshold above. Critical temperature affecting rice heat stress assumed in this study with the background of relationship between daily maximum temperature and fertility percentage of rice spikelet reported by [3,5,12] for non elevated CO2 level, [6] for lowland indica with the 7% spikelet fertility reduction for every ºC increase in temperature (1) and upland japonica with 2.4% spikelet fertility reduction for every °C increase in temperature (2), [2], and as described by the Equation 1…”

“…Flowering is the most sensitive stage in which heat stress causes a reduction in spikelet fertility and harvest index in rice [1,2,3,4]. Zakaria et al [3] found that high temperatures of from 32 to 40°C occurring from the 4th day after heading cause a decrease in panicle weight and an increase in empty grains in the upper and lower parts of the panicle. Das et al [5] reported that a temperature of 35°C or higher adversely affects panicle extrusion, flowering period and number of anthesing (opened) spikelets in rice.…”

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.

“…The optimal temperature for grain fi lling of Japonica rice in Japan was reported to be in the range from 20 to 22 C (Matsushima and Manaka, 1957;Murata, 1964;Yoshida, 1981). High temperature increases respiration rate, affects the translocation of photosynthates to grains, resulting in a decrease in grain weight, an increase in the number of sterility and partially fi lled grains, and consequently the decrease in grain quantity and quality (Matsushima and Wada, 1958;Morita, 2000;Zakaria et al, 2002). According to Terashima et al (2001), the percentage of the fi rst grade rice in Iwate prefecture in 1999 was signifi cantly lower than that in normal years because of the high temperature during the early ripening stage.…”

“…The chalky grain appearance was associated with the development of numerous air spaces between loosely packed starch granules and a change in light refraction (Tashiro and Wardlaw, 1991). The endosperm cells had many small amyloplasts containing small single starch granules (Zakaria et al 2002). Rice yields decrease with a high nighttime temperature associated with global warming (Peng et al 2004).…”

Rice grain filling is impaired by high-temperature stress during seed development. This event results in reduced grain yield and quality because of formation of smaller and chalky grains, and often causes problems in agriculture. Hightemperature stress causes disorders in primary metabolism pathways including ATP accumulation in the developing seeds. To determine the effect on the genes for ATP biosynthesis, we created the transformant rice plants in which expression of an F1-ATPase β subunit gene (AtpB) was reduced by its RNAi gene, and elevated in developing seeds by its overexpression using the GlutelinB4 promoter. The transformants, which showed a high level of ATP accumulation as well as abundant AtpB transcript in the developing seeds, showed acquired tolerance to high-temperature stress during seed development because the ratio of perfect grains without any chalky part was significantly increased. In contrast, transformants harboring the RNAi gene showed reduction of grain quality with increase of ratio of white-core and white-berry grains when they were developed in the normal growth condition. Most of these seeds never germinated, and the RNAi transgene was poorly inherited by the progenies. These results suggest that AtpB plays important roles in rice seed development and that its gene expression is strongly influenced by high-temperature stress during the grain filling stage.
