The yield and shoot growth of cuttings whose mother stocks were grown in rockwool were examined. The cultivars were autumn flowering 'Syuhonochikara' and summer-autumn flowering 'Seiun'. In the case of the autumn flowering cultivar 'Syuhonochikara' grown in rockwool, the number and weight of the cuttings increased as much as 1.7 times and 1.5 times compared to those in a soil culture. From July to August there were no significant differences in the shoot growth of cuttings originating from rockwool or soil culture, while the plant height and foliage weight of cuttings from the rockwool culture significantly increased toward the end of September, compared to those of the soil culture. By the way, in summer-autumn flowering cultivar Seiun grown in rockwool, the number and weight of the cuttings increased 1.5 times compared to those of the soil culture. No significant differences in the shoot growth of cuttings were observed between the rockwool and soil cultures. FRY percent of the visible buds were found in long-day treated shoots of cuttings from mother stocks in which cutting production was performed at three months for both rockwool and soil cultures, indicating that cutting production of cultivar 'Seiun should be done within two months
