Influence of kinetin on growth, flowering and alkaloidal contents of Hyoscyamus muticus L.
Plants treated with Kinetin responded very markedly and were more bushy and darker in colour than the controls. The physical yield was maximum in the plants treated with 50 PPM followed by 100 PPM and 200 PPM. Early flowering was induced in treated plants than the controls and it was seen first in 50 PPM. Growth and flowering was not very promising in higher concentration of the Kinetin. Height measurement indicated that plants treated with the Kinetin were larger than controls throughout the observation period. This indication was prominent in 50 PPM Kinetin treated plants followed by neat higher concentrations. Chemical assay has shown that the concentration of alkaloids has increased though it is not very appreciably as compared to the physical yield of each plant. Lower concentrations have better effects both on physical yield and alkaloids percentage as compared to the higher ones. From these observations it us assumed that the use of Kinetin as plant growth regulator on Hyoscyamus muticus is economical and its further investigations may prove more useful especially on other solanaceous plants.
