Abstract
Effects of natural growth regulators on micropropagation of potatoes
Highlights
To find the cheapest substitutes for synthetic growth regulators such as Gibberillic acid (GA3), natural growth substances that are not patent yet so named as TANG and ARQ, were evaluated for their performance in the Murashiage and Skoog (MS) medium for micropropagation of potatoes (Solanum tuberosum L.)
Maximum numbers of roots were observed in the medium supplemented with ARQ (1.87) whereas the medium containing GA3 (1.75) was second to it while minimum numbers of roots (1.375) were observed in medium having TANG (Fig. 1)
Statistical analysis shows that there was no significant difference between the natural growth substances and synthetic growth regulators
Summary
To find the cheapest substitutes for synthetic growth regulators such as Gibberillic acid (GA3), natural growth substances that are not patent yet so named as TANG and ARQ, were evaluated for their performance in the Murashiage and Skoog (MS) medium for micropropagation of potatoes (Solanum tuberosum L.). The average number of shoots plant-1 after six days of culturing indicated that the medium containing TANG produced maximum (1.37) number of shoots were observed whereas the medium supplemented with GA3 (1.12) and the medium having ARQ (1.12) induced similar number of shoots plant-1 (Fig. 9).
