Open the CIPO recordAbstract From the Canadian patent
A method of plant micropropagation is provided whereby a thin section of noncallus tissue obtained from a monocotyledonous plant such as sugarcane, wheat , or sorghum, is cultured in the presence of a cytokinin and/or an auxin. Optimal regeneration occurs when a basal surface of the thin section is oriented so as to be substantially not in contact with the culture medium. This micropropagation method produces mature monocotyledonous plants by either organogenic or embryogenic regeneration without substantial callus formation. By avoiding use of callus as a starting tissue this method reduces the , likelihood of propagated plants displaying somaclonal variation.
