Which plant growth regulators should be used under drought stress?
Under drought stress, several plant growth regulators can be used to improve plant drought resistance, reduce water loss, and increase crop yield.
The following are some specific plant growth regulators and their effects:
Brassinolide (BRs):
Known as a powerful plant growth stimulant, it activates growth enzymes in plants, promoting plant cell division and growth, and enhancing plant resistance, especially in extreme environments such as drought or climate change.
Paclobutrazol (Paclo):
By inhibiting plant growth hormones, it reduces longitudinal growth in plants, allocating more nutrients to fruits or roots, thereby improving the plant's drought resistance to a certain extent.
Sodium Nitrophenolates (Atonik):
Considered a versatile plant growth regulator, it promotes plant growth, improves disease resistance, and plays a restorative role when crops are affected by pests and diseases, helping plants maintain growth under drought stress.
In addition, the mechanisms of action of plant growth regulators include simulating or inhibiting the signal transduction pathways of hormones in plants and regulating gene expression, thereby affecting plant growth and development. When using these regulators, attention should be paid to the dosage and timing of application to avoid negative impacts on plants and the environment.
