Abstract
Leafy stem cuttings of Hibiscus rosa-sinensis L. and H. schizopetalus (Masters) Hook. f. were treated with 2 auxin concentrations and planted in 2 mist beds at different light levels in August, October and November 1969. Increased auxin and extra light tended to lessen the number and the dry weight of roots, and the proportion of rooted cuttings. Rooting was greater in H. rosa-sinensis than in H. schizopetalus. The number and the dry weight of roots, and the percentage of rooted cuttings decreased in H. rosa-sinensis and increased in H. schizopetalus from August onwards. It is suggested that endogenous growth substances rather than carbohydrates caused the seasonal patterns in rooting.
