现有的研究表明,一定浓度的富氢水(hydrogen-rich water,HRW)对植物的种子萌发和幼苗的根系生长具有促进作用。而HRW对球根类切花生长发育的影响,还未见报道。本实验采用种球浸泡及植株浇灌的方法,研究一定浓度的HRW处理对小苍兰植株生长、开花以及种球发育的影响。结果表明,与不施用HRW的对照相比,不同浓度的HRW浸泡种球和浇灌植株均显著增加了小苍兰叶片长度和叶片宽度,缩短了开花用时,增加了花茎长度、花朵直径和小花数。和对照植株相比,不同浓度的HRW浸泡种球均显著增加了小苍兰大球的直径和鲜重。10%和50%HRW浸泡种球后,小苍兰小球的数量、鲜重和干重显著增加。同样浓度的HRW浇灌植株后,大球直径、干重、干物质含量,小子球的数量、鲜重和干重显著增加。实验结果对小苍兰切花生产以及植物氢气生物学的研究,均具有重要的指导意义。
The existing research shows that a certain concentration of hydrogen-rich water (HRW) promotes the seed germination of plants and the root growth of seedlings. The impact of HRW on the growth and development of bulbous cut flowers has not been reported yet. In this experiment, we used bulblet soaking and plant irrigation methods to study the effects of certain concentrations of HRW on the growth, flowering and bulblets development of freesia plants. The results showed that the HRW immersing bulbs and watering plants significantly increased the leaf length and leaf width of freesia, shortened the flowering time, increased the length of the stem, the diameter of the flower and the number of small flowers . Compared with the control plants, different concentrations of HRW soaking bulbs significantly increased the diameter and fresh weight of freesia bulbs. The number, fresh weight and dry weight of freesia beads increased significantly after soaking the bulbs with 10% and 50% HRW. After watering the plants with the same concentration of HRW, the diameter of big ball, dry weight, dry matter content, the number of small ball, fresh weight and dry weight increased significantly. The experimental results on cut freesia cut flowers and plant hydrogen biology, are of great guiding significance.
