The experiment were carried out on the cuttings of the following plants:
Prunus yedoensis MATSUMURA.
Acer palmatum THUNB.
var. Matsumurae MAKINO.
Osmanthus fragrans LOUR.
var. aurantracus MAKINO.
by means of mist propagation.
The author resulted as follows.
1) The effect of rooting hormone (Rootone) were depended upon the kind of plants.
In Osmanthus and Acer attained highe rpercentage of rooting on each lot-viz., control, day treatment and whole day treatment, of experimental sections.
However, in Prunus were obtained not remarkable different percentage from the other sections.
2) Could not obtained the remarkable difference among the kind of rooting media.
Since the favourable results obtained both in rooting medium of loam and Kanumatsuchi on Prunus, the rooting media should be of enough draingage and so the cuttings remains erect while in constant mist.
3) The result obtained from Prunus and Acer, mist spraying looks enough be keeping the plant constantly moist only on day but not necessary on night.
However, as for Osmanthus, the highest percentage of rooting were obtained in whole day mist treatment.
According to the results obtained, it seems differs between the deciduous and ever-green trees.
4) From the result obtained from 3), probably the plant that apt to rot while on cutting should not spraying on night and with cutting bed and the kind of cutting media of enough drainage, moreover on cutting that not easily rot looks prefer with whole day mist spraying.
Notwithstanding, the author will not determine these problem this time as the above results were obtained from just a few kind of plants.
