NAA Alpha A 1 Naphthaleneacetic Acid Plant Growth Regulator

Basic Info

1-Naphthalenoacetic acid (NAA) belongs to the auxin plant growth regulator class. In addition to its basic functions as a general auxin, it can also promote the formation of adventitious roots and roots in plants, and is used to promote seed rooting, cutting rooting, and fibrous root growth in Solanaceae crops.
It can promote the rapid expansion of fruits and tubers, so it can be used as a Swelling agent on vegetables and fruit trees.
It can improve the flowering and fruit setting rate, prevent flower and fruit drop, and has anti drop function.
Not only can it increase yield, improve quality, promote lush branches and leaves, and make plants robust, but it can also effectively enhance crop resistance to early cold, waterlogging, disease, salt alkali, and stress.
