Application

Application Comment Organism
agriculture incubation of excised developing grains of ambient grown plants at 15°C, 25°C, 35°C and 45°C. Elevated temperature does not lead to a decrease in grain growth. High temperature tolerance is associated with higher catalytic efficiency of soluble starch synthase at elevated temperature and higher content of HSP 100 Triticum aestivum
agriculture incubation of excised developing grains of ambient grown plants at 15°C, 25°C, 35°C and 45°C. Elevated temperature leads to a significant decrease in grain growth Triticum aestivum
