Abstract: 
將長形山藥之塊莖催芽後,於4月下旬種植,自6月中旬起每隔1個月將植株挖掘收穫,調查塊莖鮮重、根鮮重及地上部莖葉鮮重。結果顯示,長形山藥單株之地上部莖葉鮮重於6月中旬為181.3g,6至7月間生長旺盛,至7月中旬快速增至527.2g;其後地上部莖葉之生長漸趨緩慢,地上部莖葉鮮重於9月中旬達高峰,重達636.1g;但10月起因氣溫降低,莖葉漸趨枯萎掉落,而地上部莖葉鮮重下降。在塊莖之形成與發育上,6月中旬調查時單株之塊莖鮮重即已達33.3g,顯示塊莖之形成甚早,在6月時即已形成;7月中旬時塊莖鮮重達580.0g,8月中旬調查時快速增加至1507.2g,塊莖鮮重持續增加至11月中旬達2446.0g。本研究結果可供了解長形山藥各時期地上部及地下部之生育情形,做為栽培管理時之參考。
The seed tubers of long-shaped yam (Dioscorea batatas) were planted in late April. In order to investigate plant growth and tuber development, the plants were harvested each month since the middle June. Fresh weight of tuber, root and haulm were measured. The results showed that the fresh haulm weight was Thl.3g per plant in June. From June to July, the haulm grew vigorously. The fresh haulm weight increased to 527.2g in middle July. After that, the haulm growth slowed down, and reached the maximum 636.1g in middle September. During October, the leaf fell initially, and the fresh haulm weight decreased. Considering the tuber initiation and development, the fresh tuber weight was already 33.3g per plant in middle June. It clearly indicates that tuber initiation was earlier than June. The fresh tuber weight was 580.0g in middle July, and increased quickly to 1507.2g in middle August. The fresh tuber weight continuously increased to 2446.0g in November.
