Abstract
The objective of this study was to optimize the concentration of different plant growth regulators or hormones for callus induction of cotton (Gossypium hirsutum L.). Different types and concentrations of growth regulators were tested in order to obtain the best callus formation. Four growth hormones such as 1-naphthaleneacetic acid NAP), 6-Benzylaminopurine (BAP), Kinetin and 2,4-dichlorophenoxyacetic acid (2,4–D) were used in this study. It was found that growth regulator type and concentration had a significant effect on the callus induction, the increment of callus index and callus physical appearance. The higher frequency of callus growth (95-100%) were observed on both epicotyls and cotyledon explants cultured on basal medium supplemented with 0.1mg/l NAA + 0.5mg/l Bap and various concentrations such as 0.2+0.1, 0.5+0.1, 1.0+0.2mg/l of NAA + BAP also shows good callus response but at higher concentration of the same hormones s...
