摘要: 为筛选出适宜于矾根花粉萌发的培养条件和离体培养基,本研究以矾根‘红妆魅影’为实验材料,采用单因素实验分别对培养基的pH值、培养温度及培养时间进行优化,然后用正交设计试验进一步优化矾根花粉萌发的离体培养基配方。研究结果表明当培养基pH值为5.5、培养温度为25℃、培养时间达100 min时,萌发效率最高;对矾根‘红妆魅影’花粉萌发的影响程度依次为蔗糖>PEG4000>硼酸>氯化钙;最优处理组合为A3B1C3D5(11),即在10 %蔗糖+0 mg/L氯化钙+100 mg/L硼酸+20 %PEG4000的处理组合下,矾根‘红妆魅影’的花粉平均萌发率最高达73.2%。本研究优化所得的培养基组分及培养条件可为矾根属植物有关花粉活力相关研究奠定基础。

Abstract: To screen out an appropriate medium component in vitro and a suitable cultivation condition for Heuchera plants, Heuchera ‘Hongzhuangmeiying’ was used as materials. In this study, three factors including pH value of medium, cultivation temperature, and cultivation time were firstly optimized by single factor experiments, and then an orthogonal experiment was further designed to optimize the formula of pollen germination in vitro for Heuchera ‘Hongzhuangmeiying''. The results demonstrate that the pollen germination rate is the highest when the pH value of medium is 5.5, cultivation temperature is 25℃, and the cultivation time is 120 min, and the effects of 4 factors on the pollen germination in vitro for Heuchera ‘Hongzhuangmeiying’ are as following: sucrose> PEG4000 > boric acid >calcium chloride. The best combination is the eleventh treatment (A3B1C3D5) formulated with 10 % sucrose, 0 mg/L calcium chloride, 100 mg/L boric acid, and 20 % PEG4000, and the highest average pollen germination rate attained to 73.2 %. This optimization results would give a good foundation for the studies associated with pollen vitality for Heuchera plants.
