| Abstract: | 培養兩個栽培品種的菸草Nicotiana tabacum L. cv. Wisconsin 38 (2n=48)及 Vam-Hicks (萬國士,2n=48)含單核早期至雙核晚期花粉的花葯,以觀察花粉植株之形成及花粉植株染色體的數目。W38的花葯分兩組培養,一組培養基中加1%活性碳(實驗組),另一組不加活性碳(對照組)。花葯經培養後,可以直接長出花粉植株,而植株出現的時間,因花葯的時期不同而異;單核早期的花葯形成植株所需的時間比其他時期的花葯遲一週以上。W38實驗組,W38對照組及萬國士分 Anthers of two cultivars of Nicotiana tabacum L., “Wisconsin 38” (W38) and “Vam-Hicks” (VH), containing pollen in early uninucleate stage to late binucleate stage were cultured in vitro to test the relationship between the distribution of chromosome n |
