中文摘要:
      以克隆植物积雪草为研究对象,通过添加不同剂量的挥发性有机化合物壬酸,对其组培苗的存活率、生长形态和生物量变化等进行了研究。结果发现:不同壬酸处理对积雪草组培苗的叶片数量、叶柄均长、叶片生物量、叶柄生物量和愈伤组织生物量等未产生显著影响,但对叶柄总长度、根生物量、匍匐茎生物量和总生物量等产生了显著影响。其中,6 μL和8 μL壬酸处理显著不利于积雪草组培苗的正常生长,8 μL壬酸处理下的组培苗不仅死亡率高,而且均不产生根系;2 μL和4 μL壬酸处理则有利于组培苗匍匐茎的产生,并显著提升其根系生物量、匍匐茎生物量和总生物量。本研究预示:适量的壬酸添加可以在一定程度上改变克隆植物幼苗的形态可塑性,促使其匍匐茎等克隆器官的生长,进而可能会影响其觅食行为的发生。
英文摘要:
      The survival rate, growth morphology and biomass of tissue culture seedling of clonal plant Centella asiatica were studied by adding different doses of volatile organic compound nonanoic acid. The results showed that different nonanoic acid treatments had no significant effects on leaf number, petiole length, leaf biomass, petiole biomass and callus biomass, but had significant effects on total petiole length, root biomass, stolon biomass and total biomass. Among them, 6 μL and 8 μL nonanoic acid treatment significantly damaged the normal growth of tissue culture seedlings, 8 μL nonanoic acid treatment not only had high mortality, but also did not produce roots; 2 μL and 4 μL nonanoic acid treatment was conducive to the production of stolon of tissue culture seedlings, and significantly increased the root biomass, stolon biomass and total biomass. This study indicated that the addition of nonanoic acid could change the morphological plasticity of clonal plants to a certain extent, promote the growth of clonal organs such as stolon, and then may affect the foraging behavior of clonal plants.
