Batatasins: New dormancy-inducing substances of yam bulbils.
Three growth inhibitors, for which the names batatasins I, II and III are proposed, occur in dormant yam bulbils. Application of these inhibitors suppresses the sprouting of bulbils, and the inhibition is reversible by low-temperature stratification. Batatasins I and III were isolated as crystals and partially characterized as phenotic compounds not identical with known inhibions.
