Figure 5

Schematic diagram showing the declined effect on growth and photosynthesis in response to the stimulus of hypergravity. Average percentage decrease in growth (values in red) and rate of photosynthesis, PN (values in green) with an increase in hypergravity (g) value as compared with control in wheat with ambient environmental conditions, i.e., temperature 30 ± 2°C, relative humidity 40 ± 5%. THL and THH indicate the lower threshold and the higher threshold at 400 g and 1,000 g, respectively.
