Abstract

|
|
According to the results of this experiment, the conditions for rooting of cuts could be inferred through the correlation between the supply of water and oxygen;
The moisten cutting bed was the moat suitable condition among three cutting beds (M₁ : The cutting bed with constantly watered condition, M₃: The cutting bed with constantly moisten condition, and M₂: The cutting bed with alternation of M₁, in the day time and M₂ at night) in the rooting of cuts, but M₂ produced the larger number of rooted cuts than M₃, for cuts on M₃ were apt to wither with the lack of water.
Therefore, M₃ possessed the most suitable condition as cutting bed in case of (1) the small quantities of cuttings, (2) the lack of enough time for curling work, and (3) cut roots hardly in cutting bed, while M₂ possessed the most favorable condition as cutting bed in cafe of (1) the large quantities of cuttings, (2) enough time for cutting work, and (3) cut roots easily in cutting bed.
One year old shoots from two years old mother trees were too young to be cuts; one year old shoots from ten years old mother trees were more suitable to be cuts than those from two years old mother trees.
The treatment of I.B.A. to the cuts showed the effect of shortening the rooting period and of upwardness of tooting node.
A great deal of oxygen is reqired for the functioning of I.B.A.
