How can we reduce plant growth?
Excess growth can be slowed by growing crops cooler with increased spacing and using less water, a term called growing “harder. If space allows, increase plant spacing and if crops can take colder temperatures in the 60º F range, you may want to consider this approach. Plant growth is influenced by four primary factors: light, water, temperature, and nutrients. These four factors influence the plant’s growth hormones, causing it to develop faster or slower.
What are the 5 plant growth regulators?
There are five groups of plant-growth-regulating compounds: auxin, gibberellin (GA), cytokinin, ethylene, and abscisic acid (ABA). For the most part, each group contains both naturally occurring hormones and synthetic substances. The correct answer is Abscisic acid. Abscisic acid (ABA) is a plant hormone that plays a crucial role in inhibiting growth and promoting dormancy in plants. It is known as a stress hormone because it helps plants respond to environmental stresses such as drought, salt, and cold.
