摘要: 
為瞭解不同北蔥種子含水量對種子貯藏生理影響及影響種子貯藏性之因素進行本實驗。北蔥種子於25°C、RH82%下經一天後,種子含水量提高至14%,將14%及5%含水量種子以紙袋包裝貯藏於室溫及8°C下。含水量5%的種子貯藏於8°C,種子發芽率達80%以上,於室溫下者,14%含水量種子經五個月貯藏其發芽率為0%。貯於8°C含水量5%種子內全可溶性糖及澱粉較其他處理者高出10%,於室溫下貯藏種子內五種脂肪酸較8°C下者含量增加,總過氧化物與MDA含量顯著減少10%以上,SOD及CAT分別增加13%及25%。

The objective of this research was to approach the effect of seed moisture content on welsh onion seed longevity. Welsh onion seeds with 5% or 14% moisture content were stored for five months at 8℃ or at room temperature [25±5℃/15±5℃]. Germinationof seeds stored in a paper package at room temperature was significantly lower around 80% than that of seeds stored at 8℃. For seeds with 5% moisture content stored at 8℃, germination was greater than 80% after stored for 5 months, CO2 production was 210 μ1/ g FW/hr , and soluble sugar content were 60 mg/g DW. For three seeds, total peroxide and malondialdehyde (MDA) content were 60 mg/g DW.For three seeds, total peroxide and malondialdehyde (MDA) content were 10% lower, superoxide dismutase (SOD) activity was 13% higher, and catalase (CAT) activity was 25% higher than in seeds stored at 8% with 14% moisture content.
