| 摘 要： | 【研究目的】探讨台湾桤木花粉萌发的适宜培养基组成、培养温度及台湾桤木花粉生活力的快速测定方法。【方法】以台湾桤木新鲜花粉为试材,采用花粉离体培养萌芽法及TTC染色法、I2-KI染色法、过氧化物酶沉淀法等方法进行研究。【结果】台湾桤木花粉离体培养的适宜培养液为:10%蔗糖 100mg/L硼酸;最适培养温度为25℃。过氧化物酶沉淀法是快速测定台湾桤木花粉生活力的适宜方法。【结论】蔗糖和硼是台湾桤木花粉萌发的必要条件。

| Abstract: | [OBJECTIVE]In order to study the suitable media components,temperture of Alnus formosana pollen,and the fast detetminination method of its pollen viability.[METHOD]With fresh pollen of Alnus formosana as the experimental material,in vitro culture and 3 staining tests(TTC staining,I2-KI staining and peroxidase settling process)were conducted to determine the pollen viability.[RESULTS]The optimum culture solution was sucrose 10g/L H3BO3 10mg/L.Peroxidase settling process was the optimum staining for the fast determination of Alnus formosana pollen viability.[CONCLUSION]Sucrose and H3BO3 were essential for pollen germination of Alnus formosana. |
