'''發芽'''（Germination）是指植物從種子中或真菌從孢子中發出的過程。在園藝上多指的是胚根從種皮突出的狀態，但廣義來說，發芽可以指任意一個從小的存在或[[生殖细胞]]展開擴大的過程。

==== 發芽率(germination percentage)： ====
發芽種子數佔總播種種子數之百分率。

==== T<sub>50</sub>： ====
達到發芽率50%所需要的時間。

==== 平均發芽日(mean germination time, MGT)： ====
<math>MGT=\frac{\sum({fi}\times{di})}{N}</math>，fi：播種後第i天之發芽數。di：播種後天數。N：發芽試驗期間之總發芽數<ref>{{Cite journal |last=Ellis |first=R. H. |last2=Roberts |first2=E.
