“…Quinoa pollen viability was reduced significantly due to high temperature (40/24°C) ( Figure 2). The reduction of pollen viability by high temperature has been reported in different crops including maize (Herrero & Johnson, 1980), sorghum (Prasad, Boote, Allen, Sheehy, & Thomas, 2006), groundnut (Prasad, Craufurd, & Summerfield, 1999), pearl millet , wheat (Dwivedi et al, 2017;, tomatoes (Pressman, Peet, & Pharr, 2002;Zhou et al, 2017), cotton (Kakani, 2005) and beans (Porch & Jahn, 2001). Pressman et al (2002) suggested that the reduction of pollen viability in tomato is due to the lower soluble sugar concentration in the developing pollen grains.…”

Quinoa (Chenopodium quinoa Willd.) has gained considerable attention worldwide during the past decade due to its nutritional and health benefits. However, its susceptibility to high temperatures has been reported as a serious obstacle to its global production. The objective of this study was to evaluate quinoa growth and pollen morphology in response to high temperatures. Pollen morphology and viability, plant growth and seed set, and several physiological parameters were measured at anthesis in two genotypes of quinoa subjected to day/night temperatures of 22/16°C as a control treatment and 40/24°C as the heat stress treatment. Our results showed that heat stress reduced the pollen viability between 30% and 70%. Although no visible morphological differences were observed on the surface of the pollen between the heat‐stressed and non‐heat‐stressed treatments, the pollen wall (intine and extine) thickness increased due to heat stress. High temperature did not affect seed yield, seed size and leaf greenness. On the other hand, high temperature improved the rate of photosynthesis. We found that quinoa has a high plasticity in response to high temperature, though pollen viability and pollen wall structure were affected by high temperatures in anthesis stage. This study is also the first report of quinoa pollen being trinucleate.

“…is susceptible to heat stress Lidon, 2010 andWang et al, 2016). Optimum temperature during wheat anthesis and grain filling ranges from 12-22°C (Farooq et al, 2011 andDwivedi et al, 2017). Wheat yield declines by 3-4% for every 1°C increase above 15°C and grain number decreases by 12.5% as temperature increases by 1°C from 25/20 to 35/20°C day/night (Wardlaw & Wrigley, 1994).…”

With the changing climatic scenario and increasing global mean temperature, heat stress became a major limiting factor for today's agriculture. To identify the underlying mechanism associated with heat tolerance in peanut, two experiments (field and growth chamber) were conducted with four genotypes (ICGS 44, GG 7, AK 159 and DRG 1) having differential high temperature stress sensitivity. Field grown plants under three different temperature (D1, D2 and D3) regimes simulated three temperature treatment effects with a variability of 3–4/4–5°C in mean day/night temperature, respectively. In growth chamber, imposition of heat shock (10°C above ambient inside growth chamber) revealed not only rapid induction (within 0.5 hr) of HSPs, especially small HSPs (HSP 17, HSP 40) in tolerant genotypes, but also its sustenance for longer duration (2 hr), which might help them to have better physiological adaptation strategies under high temperature stress. This was evident from significant advancement in phenophases observed with increase in temperature by 15–18 days at physiological maturity, while pollen viability and membrane stability reduced below 50% and 41%, respectively in DRG 1 with increase in mean day/night temperature. Maintenance of higher photosynthesis and transpiration rate and stomatal conductance helped the tolerant genotype ICGS 44 to keep relatively cooler canopy and higher photosynthates, ensuring better physiological condition in this genotype under heat stress. Significant increase (~2.5‐fold) in inositol and hexoses (glucose and fructose) content and reduction (>50%) in sucrose content in leaf tissues indicated degradation of storage carbohydrates for improved osmotic adjustment especially in tolerant genotypes under elevated temperature.
