Abstract
|
|
|
The rootability of hardwood cutting of mulberry (Morus alba L.) depending upon the kinds of cutting beds, soil of cutting beds, effect of growth regulator (Rootone-F), pretreatments of cutting scion, parts of branches were investigated, The results were as follows;
1. Rootability was the highest is cutting after callus formed on sand bed, whereas null in the treatment of rice seedling hot bed.
2. Optimum cutting season was around March 26, showed 100% rootability in all treatments except wooden box filled with sand.
3. The order of rootability related with cutting gart of branch was upper<middle<lower, however 70~100% rootability showed in cutting after callus formed, even in upper and middle part.
4. Growth regulator, Rootone-F, increased rootability in upper and middle part cutting than without growth regulator, and in 20cm depth hot bed. However, the rest of treatments was not shown the clear effect.
5. No distinctive differences were not showen in rootability related with bed soils.
6. The pretreatments such as cutting after preservation of branch (cut on March 15) for 2-5 weeks in ice warehouse (Temp. 5-7°C), and cutting after formation of callus increased rootability, whereas cuttings left in open air for 5 days showed null rootability.
