Ethephon is a common plant growth regulator, which is widely used all over the world. It mainly promotes seed germination, flowering and fruiting, ripening and falling. Ethephon mainly enters into plants through leaves, bark, fruits and seeds, and then spreads to the active parts to release ethylene. It can promote the ripening and coloring of fruits, promote the shedding of leaves and fruits, dwarf plants, change the ratio of male and female flowers, and induce male sterility of crops. Ethephon can be used in a variety of crops, such as rice, corn, Jinqiu pear, grape, peach, tomato, cucumber, melon, cotton, etc. For example, the application of ethephon in cotton can accelerate the boll cracking, reduce the flower after frost, effectively improve the quality of cotton, so as to improve the yield of cotton.
