Abscisic acid (ABA) In Cannabis Growing

Abscisic acid (ABA) is a plant hormone that is naturally produced by cannabis plants and plays a critical role in their growth and development. It is an essential component of the plant’s signaling system and helps to regulate a variety of physiological processes, including seed dormancy, drought tolerance, and stress response.

In cannabis plants, ABA is synthesized in response to a variety of stressors, including drought, heat, and high salinity levels. When the plant experiences these stressors, ABA is produced in the roots, leaves, and other tissues and travels throughout the plant via the vascular system.

One of the primary functions of ABA in cannabis plants is to regulate water use and prevent dehydration. When the plant is under stress, ABA triggers the closure of stomata, the tiny pores on the surface of leaves that allow for gas exchange. This reduces the amount of water lost through transpiration, helping the plant conserve moisture.

ABA also plays a role in seed development and germination. It can induce seed dormancy, preventing the seed from germinating until conditions are favorable for growth. This can be important for ensuring that seeds do not germinate during periods of drought or other unfavorable environmental conditions.

In addition, ABA helps to regulate the plant’s response to other hormones, such as auxin and gibberellins, which control growth and development. ABA can inhibit cell division and expansion, which can help the plant conserve resources during periods of stress.

Overall, ABA is a critical component of the plant’s stress response system, helping to ensure that cannabis plants can survive and thrive under a wide range of environmental conditions. Understanding the role of ABA in cannabis plants can help growers optimise cultivation practices and improve crop yields.
