Abstract

|
Rooting of Ficus benjamina and Ficus nitida stem cuttings was experimented to see the comparative effect of NAA, IBA and ethychlozate (trade name: Figaron), and the results are summarized as in the following compendia;
1. When soft-wood cuttings of new shoot from the two species were taken and dippingtreated with either NAA, IBA or ethychlozate at varied concentration levels, their rootings were mostly more superior to the control for without the growth-regulant treatments. Appropriate level of these auainic substances for the cutting practice was regarded approximately 200㎎/ℓ of either NAA or IBA for 30 minutes, and 10㎎/ℓ of ethychlozate for 30 minutes, while number of roots produced and rooting rate were greatest with NAA, IBA and ethychlozate in that orde.
2. Relatively high-molecular nutritive substances as protein and starch in the cuttings seemed to increase for the first stage of the cutting period and then either gradually decreased or no distinctive change in the quantity occurred as rooting of the cutting progressed toward the end of the cutting period, whereas soluble substances as sugars in the cutting decreased quantity-wise as the time went on. This seems to indicate the fact that immediate use of the water-soluble sugars takes place most likely to maintain the survival and rooting of the cutting.
