Since the intensive cultivation of peach needs a lot of nursery trees at a time, cheap nursery trees producing method via simple process have been detected in this experiment using $quot;Sunagowase$quot;, $quot;Okubo$quot;, and $quot;Yumyeung$quot; peach cultivars. Hardwood cuttings obtained from different and softwood cuttings treated different etiolation period have been carried out to determine the optimum seasons of hardwood cuttings and the effect of etiolation period on the performance of softwood cuttings. The summarized results are as follows.
1. The peach cultivar $quot;Sunago-wase$quot; gave the highest rooting percentage compared to $quot;Okubo$quot; or $quot;Yumyeung$quot; cultivar.
2. The optimum time of hardwood cuttings has been found to be late January judging from the rooting, root number, root length and root fresh weight regardless of the differences of cultivars examined.
3. The $quot;Sunago-wase$quot; peach cultivar, has higher root development than $quot;Yumyeung$quot; cultivar and showed higher contents of N, P, K, Ca and total content of carbohydrate in the bark of hardwood cuttings.
4. Regardless of the difference of cultivars, the total carbohydrate contents from hardwood cuttings of January 28, which time showed the highest root development, were higher than those from hardwood cuttings December 28, February 28 and March 20.
5. Providing softwood scions the pre-etiolation treatment prior to putting cuttings in the bed in a mist room showed higher rooting percentage than rooting of the cuttings without pre-etiolated control. While, etiolating for 35 days gave the best rootability compared to 25 or 45 days treatment.
