In vitro tuberization of potato sprouts as affected by ethrel and gibberellic acid

Summary

In vitro tuberization of etiolated potato sprouts was considerably advanced by a dose of 50 ppm ethrel (2-chloro-ethyl-phosphonic acid). The adition of ethrel also increased the number of tubers, produced shorter and thicker stolons and reduced root development. Some of these effects are opposite to those induced by gibberellic acid which is known to retard tuberization and to promote elongation. When both substances were simultaneously supplied to the medium, they showed a clear antagonistic interaction.
