The intermediate naphthyl methyl radical was formed during the reaction of sulfate radical anion with NAA. [5] In micropropagation of various plants, NAA is typically added to a medium containing nutrients essential to the plants' survival. It is added to help induce root formation in various plant types.

When the apex of the plant is removed, the inhibitory effect is removed and the growth of lateral buds is enhanced. This is called decapitation, usually performed in tea plantations and hedge-making. Auxin is sent to the part of the plant facing away from the light, where it promotes cell elongation, thus causing the plant to bend towards the ...

Neutron activation analysis is a sensitive multi-element analytical technique used for both qualitative and quantitative analysis of major, minor, trace and rare elements.. NAA was discovered in 1936 by Hevesy and Levi, who found that samples containing certain rare-earth elements became highly radioactive after exposure to a source of neutrons
They are used to regulate the growth of cultivated plants, weeds, and in vitro-grown plants and plant cells; these manmade compounds are called plant growth regulators (PGRs). Early in the study of plant hormones, "phytohormone" was the commonly used term, but its use is less widely applied now.
