Effect of Some Phenolic Compounds and Gibberellic Acid on Growth and Development of Cheena Millet (Panicum Miliaceum L.)

Gibberellic acid (GA₂) and phenolic compounds salicylic acid (SA), β-naphthol (β-N), ehlorogenic acid (CA) and tannic acid (TA) hasten the emergence of ears and increase plant height, number of grains and 1, 000-grain weight in cheena millet (Panicum miliaceum L.). The effect of treatment with some combinations of G A, with a phenol was more than with the phenol alone. It is suggested that the effect of phenols may be mediated through an increase in mobilization of reserve food materials and is not related to their structural configuration as is considered by some workers.
