What symptoms can flowers appear after high temperature injury? How to carry out nursing?

After flowers are injured by high temperature, many physiological mechanisms are abnormal, photosynthesis is inhibited, necrotic spots appear on leaves, chlorophyll is destroyed, leaves turn yellow and brown, and even lead to plant death.

For flowers injured by high temperature, they should be shaded or moved to shade places in time, and those indoors should be opened for ventilation in time, and should not be watered immediately, but should be sprayed or watered after the temperature drops below 30 ℃ to prevent physiological drought. After several days of careful maintenance, it can generally recover, but the injured chloasma on the leaves will stay with the leaves for the rest of their lives.
