Abstract
臺灣一葉蘭為高山落葉性蘭科植物中之球根花卉，原產於臺灣海拔1,500~2,000m山區。球莖每年更新，經低溫打破休眠後於室溫下定植三星期開花，球莖貯運及促成栽培特性，可與鬱金香相抗衡。定植時母球已具子球及孫球三代同堂。球莖自第一年茅體之發生，第二年花茅形成，第三年之開花結球，至第四年之供應養分與老化，歷時3.5年。
生長於海拔2,100m南役縣梅舉山區，較海拔1,200m霧社為佳，臺北平地所種之球瘦小，花芽分化途中遇夏天高溫夭折。花芽形成及生長適溫在15~20℃，夜溫超過25℃，不會花芽分化。母球具5g以上者，具60%以上開花率，球愈大開花率愈高，個體增殖率亦愈大，但祗2~3倍而已。可依球產量高低，受繁殖母球大小、個數及重量增殖倍數及栽培密度而定。
Pleione Jormosana Hayata is an alpine orchid which has annually replaced corms and single decidous leaves. The sprouting and anthesis occurs three weeks after cold storage (5℃ for 2 months). The life span of Pleione formosana is about 3.5 years. The life processes runs from bud visibility in the first year, to flower formation in the second year, anthesis and bulbing in the third year, through nutritional supply for anthesis and early daughter corm growth and senescence in the fourth year.
Dry weight of daughter corms grown in the high altitude of Mei-Feng (2100 m) are greater than corms grown at Wu-Shah (1200 m) and Taipei (50 m). Flower initiation occurs after the leaf has fully expanded while the corm is growing actively. The optimum temperature for growth and flower differentiation in ranges 15-20℃. Flower initiation cannot occur at night temperature above 25℃.
The marketable size of corm is above 5 gram which has 60 percentage of flowering. The production of salable corns depends on size of mother corms, number and weight increase and planting density.
