“…Due to their economic importance, the effect of temperature stress on the reproductive process has been extensively studied in cereals (see Barnabás et al, 2008 andThakur et al, 2010 for extensive reviews on the subject). Special mention must be given to the work done in rice (Oryza sativa L.), initiated in the 1970s by Japanese researchers (Nishiyama, 1984;Satake and Hayase, 1970) and later confirmed by many authors (e.g.…”

Research on plant responses to temperature stress is receiving increased interest due to the growing awareness about global warming. High and low temperature stresses help establish the narrow geographic distribution of some cultivated plants, the limited geographic extension of some other economically nutritionally important species, and also induce irregular bearing for some species. However, the understanding of plant responses to temperature stress lags behind other biotic and abiotic stresses probably due to the complex response at the molecular, cellular, and organismal level. Temperature stress affects, indeed, many developmental processes during the plant's life cycle. However, the reproductive stage, the outcome of which represents the economic value for many cultivated plants, is especially vulnerable. Here the effect of low and high temperature stresses during the flowering phase is reviewed in flowering plants in an attempt to unravel sensitive stages that are behind irregular cropping. The review presents detailed findings from 33 previously published reports spanning 19 different flowering plant species. Both the male and female organs of the flower are especially sensitive to temperature fluctuations both during their development before pollination and during the post-pollination stage. The effect of temperature stress is, however, obscured by the complex male-female interaction superimposed on the individual behavior of each organ. Interestingly, a review of the literature on this topic shows that genetic variation does exist in reproductive behavior under temperature fluctuations. This genetic diversity must be preserved and characterized in further detail to understand how plants naturally cope with changing environmental conditions, which will, undoubtedly, help us to design better strategies to face current and future challenging temperature fluctuations.

“…To overcome a similar phenomenon and to account for the asynchronous floral development in a rice panicle, marking protocol has been used to quantify heat stress impact during anthesis (Jagadish et al 2008(Jagadish et al , 2010a. More importantly, cold (Thakur et al 2010) and heat stress (Hedhly 2011) are known to delay and enhance most developmental stages, respectively, making it impractical to extend progress achieved with cold stress phenotyping directly to study heat stress. Hence, a phenotypic marker to quantify heat stress impact at microsporogenesis stage needs to be identified and extensively tested for extending its applicability across different rice genotypes and environmental conditions.…”

Abstract. Gametogenesis in rice (Oryza sativa L.), and particularly male gametogenesis, is a critical developmental stage affected by different abiotic stresses. Research on this stage is limited, as flowering stage has been the major focus for research to date. Our main objective was to identify a phenotypic marker for male gametogenesis and the duration of exposure needed to quantify the impact of heat stress at this stage. Spikelet size coinciding with microsporogenesis was identified using parafilm sectioning, and the panicle (spikelet) growth rate was established. The environmental stability of the marker was ascertained with different nitrogen (75 and 125 kg ha -1 ) and night temperature (22 C and 28 C) combinations under field conditions. A distance of -8 to -9 cm between the collar of the last fully opened leaf and the flag leaf collar, which was yet to emerge was identified as the environmentally stable phenotypic marker. Heat stress (38 C) imposed using the identified marker induced 8-63% spikelet sterility across seven genetically diverse rice genotypes. Identifying the right stage based on the marker information and imposing 6 consecutive days of heat stress ensures that >95% of the spikelets in a panicle are stressed spanning across the entire microsporogenesis stage.

“…For example, changes in the variability of temperature can greatly influence dry matter production as both high and low temperatures decrease the rate of dry matter production and, at extremes, can cause production to cease (Grace, 1988;Ingver, Tamm, Tamm, Kangor, & Koppel,, 2010). Likewise, water deficit occurring immediately before flowering can lead to pollen sterility and will result in a drastic decline in grain yield (Ingver et al, 2010;Nguyen & Sutton, 2009;Thakur, Kumar, Malik, Berger, & Nayyar, 2010). Previous research relating predicted climatic variations to crop response have offered the potential to anticipate changes in crop production early enough to adjust critical decisions (Blench, 2003;Hansen, 2002;Letson et al, 2001).…”

“…In the grains group we chose barley, spring wheat, oat, canola, and dry peas. Grains have been documented (Joshi et al, 2011;Subedi, Gregory, Summerfield, & Gooding, 1998;Thakur et al, 2010;Willenbockel, 2012) to be very vulnerable to changes in temperature and precipitation; therefore historical data on grain yields can serve as proxy to understand future effects of variable weather conditions. Likewise, fruits such as blueberries and raspberries, as well as vegetables such as green beans are susceptible to water deficit.…”

The goal of this research was to model the potential impact of climate change on food production, in the Fraser Valley and Peace River regions of British Columbia (BC), using historical crop yield and climate data. We identified eight indicator crops of importance for these regions of BC and utilized historical Census of Agriculture and climate data (temperature and precipitation) to model future potential impacts of climate change on agriculture. We developed three climate change scenarios for these eight indicators crops (extreme, moderate, and business as usual). Under the most extreme climate model scenario the Fraser Valley is expected to experience cooler summers and springs and wetter summers, with incremental increases in oat, blueberry and green bean yields by 2050. These same climate conditions were predicted to decrease the yields for raspberry crops by 2050, while barley and wheat crop yields remain steady. The business as usual scenario, where springs and summers are warmer and summers are wetter in the Fraser Valley, predicted increased barley, oat, wheat, and blueberry crop yields by 2050, while yields of raspberries were predicted to decrease and green bean yields are expected to be steady. Under the more conservative climate change scenario conditions, yields should remain steady for all crops, except green beans where yields will increase by 2050. Future climate conditions for the Peace River area were much different from the Fraser Valley. All three scenarios forecasted warmer and wetter springs and summers with decreased evapotranspiration and moisture deficits. These changes in climate conditions predicted declines in wheat, canola, and barley crop yields by 2050, while incremental increases in oat and dry pea crop yields could be expected by 2050.
