“…The results of our experiment confirmed that the rise of environment temperature to the optimum level was followed by a significant increase in seedlings dry matter; twenty day after sowing DMplant at 24°C was 71% higher than at 18°C. Similar effects of environment temperature on dry matter weight of the root system and the whole plant are reported in cauliflower (Kuç i et al, 2012), Arabidopsis (Zhu et al 2015), and rice (Kiet and Nose, 2016). The difference in DMplant was mostly a consequence of sharp increase in DMshoot.…”

The effects of different environment temperatures, priming treatments and priming durations on germination parameters and early growth of pepper seedlings were investigated. Seeds were hydro primed in distilled water, or osmo primed in two different water potentials (-0.15 and -0.5 MPa) of polyethylene glycol (PEG) 8000. Both, hydro primed and osmo primed seeds were subject of two different imbibitions periods, 48 and 72 hrs. In addition to primed seeds, an equal sample of non primed seeds was included in the experiment as a control variant. Following priming, the seeds were subjected to germination tests at two different environment temperatures, respectively 18 0C and 24 0C. In general, there was no significant effect of hydro priming on germination parameters or early growth of pepper seedlings. On the contrary, significantly higher germination percentage and germination speed and significantly shorter mean germination time than the non primed seeds were obtained due to seed osmo priming by PEG. Similarly, an enhanced seedling growth, especially under suboptimum temperature conditions was evidenced in PEG primed seedlings. Apart from germination speed, the increase of PEG concentration from -0.15 to -0.5 MPa had no effect to germination parameters of pepper seeds. The extent of the imbibitions period over 48 hrs did also have no benefits on germination parameters.

“…An elevated temperature promotes the ripening and reduction in grain weight because of shortens the duration of grain filling, which ultimately reduces yield. Rice exposed to 10 °C elevated temperature than ambient, at heading and anthesis, reduced photosynthesis which might be due to structural changes in the organization of thylakoids and the loss of stacking of grana in the chloroplast ( Kumar et al., 2015 ; Kiet and Nose, 2016 ).…”

Increasing atmospheric temperature is the consequence of global warming, which is expected to influence crop growth and development, resulting in declining productivity in the tropical agriculture system. The selection of temperature tolerant crop cultivars with higher productivity to meet the future demand of the world expanding human population requires a thorough understanding of crop growth feedback to increasing temperature. Therefore, a field experiment was conducted during the Kharif season of 2012 and 2013 to understand the response of yield and yield-related traits of eleven rice cultivars to elevated temperature grown inside field mounted temperature gradient tunnel (TGT) in the Bhabar region of the Indian Himalayas. The elevated temperature significantly impacted growth and yield and yield-related traits, especially tillers, panicles, filled and chaffy grains, grain, and 1000 grain weight, yield, and harvest index of all the cultivars during both years. The cultivars, i.e.

“…The rate of photosynthesis decreases when the temperature increases above the optimum value for plant growth [25], and it has thus been shown that a reduced ripening period leads to an inadequate accumulation of carbohydrates and to a decrease in yield due to increases in sterility and immature grains [26][27][28][29][30]. In the present study, the yields were significantly higher in the Si application compared to the control.…”

The Increase in the Arsenic Concentration in Brown Rice Due to High Temperature during the Ripening Period and Its Reduction by Silicate Material Treatment

We investigated the effect of temperature during the ripening period on the rice yield and arsenic (As) concentration in brown rice, using temperature gradient chambers (TGCs). Rice grown in Wagner pots (1/5000a) was placed in three TGCs (each TGC was set at four temperature levels: ambient, mildly-high temperature, moderately-high temperature, and super-high temperature) from one week after heading until harvest. In the TGCs, a range of mean air temperatures was observed in the range of 2 °C above the ambient temperature. There was a significant negative correlation between the brown rice yield and the air and soil temperatures, and the increase in air and soil temperatures resulted in a decrease in the yield. The reduction in yield was significantly mitigated by the application of calcium silicate. The concentration of As in the brown rice was significantly positively correlated with the air and soil temperature, and the concentration of As increased with increasing air and soil temperatures. When calcium silicate was applied, the concentration of As in brown rice was significantly lower at all temperature ranges, and its application was effective in reducing the arsenic concentration even at high temperatures. These results suggest that the application of silicate material may help mitigate the decrease in yield and the increasing As concentration in brown rice even under high-temperature conditions.
