迷迭香水培诱导生根繁殖技术研究

为探讨生物植物生长调节剂对迷迭香水培诱导生根的可行性及其最佳营养液,分析了9种不同配比生物植物生长调节剂以及9种不同配比营养液对迷迭香根系生长特性的影响。结果表明,在水培条件下,迷迭香根系可正常生长,且吸收功能正常。自制植物生长调节剂椰子汁50 g/L最有利于迷迭香的生根诱导培养;诱导迷迭香水培生根最适的营养液配比为硼酸30 mg/L、硝酸铵40 mg/L、VB130 mg/L、磷酸二氢钾40 mg/L,迷迭香植株生长势最强。

月季花色炫丽、香气怡人,深受人们的喜爱。选取月季的嫩枝或当年生硬枝插入"水基质"中,提供适合的环境条件,利用自身的再生能力长出根系,该繁殖方法清洁、易操作,被养花爱好者所采用。

几种室内观赏植物的水培试验

试验以3种室内观赏植物富贵竹、豆瓣绿和绿萝为材料,研究了营养液种类和换液间隔天数对3种水培植物生根的影响。结果表明:3种植物在浓缩营养液中生长良好,且发根快、生根多、根长而粗壮,生根率高;其中,绿萝发根最早且根长,豆瓣绿的根粗壮,它们的生根率均达到95%以上。

Propagation of Abies beshanzuensis by Water Cultured Medium

[Objective] The experiment aimed to explore the influences of phytohormones (ABT and IAA) and nutrient solution on rooting of Abies beshanzuensis M.H.Wu by water cultured medium. [Method] The Abies beshanzuensis M.H.Wu were treated by water (CK), 10 mg/L ABT+ water, 10 mg/L IAA+ water, 10 mg/L ABT+ hoagland solution, 10 mg/L IAA+ hoagland solution, then the rooting process was observed and the formation rate of callus, rooting rate, number of rooting, and root length were investigated and analyzed. [Result] ABT and IAA had obvious influences on callus induction, rooting rate and the number of root of Abies beshanzuensis M.H.Wu by water culture, so they were suitable to be used in water propagation of Abies beshanzuensis M.H.Wu. The treatments of phytohormones had no regular influences on the longest root length and average root length. The nutrient solutions would not generate obvious influence on propagation of Abies beshanzuensis M.H.Wu at firstly stage, but they generated influence on root growth after rooting. [Conclusion] The research provided new ideas for propagation of Abies beshanzuensis M.H.Wu, which could make it out of endangerment situation quickly.

Tissue Culture and Gemmae Propagation of Shoot Tipof Huperzia serrata

To solve the problems of microbial contamination and no rooting during the tissue culture of Huperzia serrata, wild seedlings of Huperzia serrata were cultured by indoor hydroponics or soil cultivation methods, then the stem tips were used in tissue culture. The above operation significantly reduced microbial contamination during tissue culture process. Different types and concentrations of hormones were added into the basic medium MS to screen the optimal formula for induced plantlet growth and rooting. It was found that 1/2MSCO was the best medium on which stem, leaves and roots of tissue culture plantlets of Huperzia serrata grew quickly. At the same time, sand planting was a convenient and effective approach for gemmae propagation of Huperzia serrata, the survival rate of seedlings germinated from gemmae was nearly 100%.
