What is the suitable temperature for the growth and development of sorghum?
What kind of temperature is suitable for the growth and development of sorghum? Please provide an introduction. The optimum temperature for sorghum seed germination is 18-35°C. If the temperature is too high, the seedlings will be tall and spindly; if the temperature is too low, in severe cases the seeds will rot, and in mild cases the seedlings will grow slowly. The optimum temperature for seedling growth and development is 20-25°C, and the suitable temperature during jointing and booting is...
What kind of temperature is suitable for the growth and development of sorghum? Please provide an introduction.
The optimum temperature for sorghum seed germination is 18-35°C. If the temperature is too high, the seedlings will be tall and spindly; if the temperature is too low, in severe cases the seeds will rot, and in mild cases the seedlings will grow slowly. The optimum temperature for seedling growth and development is 20-25°C, and the suitable temperature during jointing and booting is 25-30°C. The suitable temperature during heading and flowering is 26-30°C. If the temperature is too high, it can cause the pollen of some spikelets to shrivel and become ineffective; low temperatures can cause the glumes not to open, the anthers not to dehisce, a reduction in pollen amount, and a delay in the flowering period. In the late growth stage, the suitable daily average temperature is 20-24°C. When the daily average temperature drops below 16°C, grain filling stops.
