Effect of Carbon Dioxide and Ethylene on Tuberization of Isolated Potato Stolons Cultured in Vitro

Abstract

Carbon dioxide stimulates tuberization of isolated potato (Solanum tuberosum L.) stolons cultured in vitro. The stimulatory effect is inhibited by C2H4 which is by itself also inhibitory of tuberization. Furthermore, C2IL inhibits kinetin-induced tuber initiation. Both the formation and elongation of roots are inhibited by C2H4. The antagonistic actions of C02 and CH4 on tuberization are discussed.
