The effects of rooting volume restriction on leaf number、leaf area、weight of various organ,and flower quality at 30、73、107、 172 days after transplanting (DAT) were significant. Growth was positively cor related with container volume,but the tuber weight was similar among the conta iners. Plants of cyclamen were shown to flower earlier when grown in 130ml pot s. Total flower number、flower longevity ,and flower quality were greatest wit h container size increased. Cyclamen plants with flower bud 1-2 mm ,treated wi th 25ppm GA3 (5ml) could flower earlier by 1-2 months. Plants grown in 240ml c ould flower earlier than other container size.

Ebb and flow sys tem was suggested to be not suitable in cyclamen , especially in spring and su mmer.The proposed miniature cyclamen production in Taiwan was as follows: (1) Seeds sown in February and March, the plug seedlings transferred to highlands for growing from summer to fall , transplanted to 130-240ml pots, and then sol d from October to Christmas ; (2) For growers in lowlands: buy the liner (130- 240ml pot) from highlands in fall ,and transfer the liner to 450-650ml pots, u sing cooling system to hasten flowering, and then sold the plants from the Chi nese New Year to March. The display period lasts for 3 months. Lee,Nean 李哖 --- 1998 學位論文 ; thesis 100 zh-TW
