[請益] 又是關於試驗單位的問題 麻煩大家...幫我解惑一下
今天報告了試驗單位
大家對於組培培養基配置有點疑問
想來問問大家
我是拿複因子講義p.10的金線蓮組織培養來當例子
試驗目的:比較施用三種cytokinins對金線蘭莖節培養癒傷組織誘導的效果
處理方式:
於基礎培養基分別加入A.B.C三種cytokinins,再分裝到30個錐形瓶
每個錐形瓶內接種5個莖節。
講義上有提到,每個處理只有一個試驗單位,這個實驗要重新做過才能評估再現性。
但是...台下的大家都覺得每個重複都要重新配培養基,
在實際執行上並不可行(處理多的時候工作量會太多)
他們認為重複是為了控制植物材料的不確定性
藥品的純度很高,這樣重複的是沒有意義的...
他們認為每個錐形瓶是一個試驗單位
裡面的金線蓮是抽樣單位
請問大家我要怎麼解釋會比較好呀!!!
....................................................................
P.S. 做肥料試驗的時候,每個重複的肥料應該要重新配置
還是用同一次配置的肥料施用在不同植物就好....
麻煩大家幫我解惑一下^^
