Abstract: This paper describes a cutting experiment in closed plastic bags in sweet-scented osmanthus, Japanese late cherry, sweet cherry and apple. Semilignified or fully lignified cuttings of three nodes with two half-leaves were used in the experiment. After being treated with hormonal solution, the cuttings were inserted in moist rooting media contained in clear plastic bags. The plastic bags were then sealed and placed at an open site. Shade was provided when temperature was too high on sunny weather in summer and early autumm. It was shown that the temperature in the plastic bags was relatively stable and acceptable for the cuttings and the media stayed moist throughout the experiment. The leaves of the cuttings were turgid. Callus occurred about one week after cutting and roots were produced three to four weeks later depending on the plant materials, media and shading regiemes. All the plant species used in the experiment were successful in root formation though varying in rooting rate. A rooting rate of more than 70% was achieved in Japanese late cherry cuttings subjected to the combination of "Emei Xiantu" media and shading during 10:00-17:00 on sunny weather in June.
