中文摘要:
      为研究醇提莪术对绿豆种子萌发及幼苗生长发育的影响,在不同浓度梯度醇提莪术溶液作用下对绿豆种子进行浸种试验,来判断中药莪术是否可作为植物源生长调节物质。采用室内水培,培养皿纸上发芽法,分光光度法测定叶绿素含量,蒽酮比色法测定可溶性总糖的含量。试验结果表明,醇提莪术对绿豆种子萌发及幼苗的生长有明显的低浓度促进、高浓度延缓作用,且延缓效果随溶液浓度的升高而升高;绿豆种子的发芽指标及幼苗的根长、株高、下胚轴长、鲜重、干重及根冠比均呈先增长后下降的趋势,其生长最适浓度在150 mg/L。绿豆幼苗叶绿素含量及可溶性总糖含量也呈先增大后减小的趋势,其有机物质积累最适浓度在300 mg/L。研究结果表明醇提莪术溶液低浓度促进植株生长,但不利于有机物质积累;较高浓度延缓植株生长,但有利于有机物质的积累。
英文摘要:
      To study the effects of Curcuma zedoaria with alcohol extraction on seed germination and seedling growth of mung bean, we conducted a soaking test of mung bean with different-concentration gradients of Curcuma zedoaria with alcohol extraction to determine whether the traditional Chinese medicine Curcuma zedoaria could be used as a biological plant growth hormone. We used the indoor hydroponics and germination on the petri dish paper. The content of chlorophyll was determined by pectro photometric method and the contents of soluble sugar were determined by anthrone colorimetry. The results showed that: the seed germination and seedling growth of mung bean were promoted by low concentration, were delayed by high concentration, and the delayed effect increased along with the increasing concentration. The germination index, root length, plant height, hypocotyl length, fresh weight, dry weight and root-shoot ratio increased first and then decreased, and the optimum concentration was 150 mg/L. The chlorophyll content and soluble sugar content of mung bean seedlings also increased first and then decreased, and the optimum concentration of organic matter was 300 mg/L. The results indicated that the low concentration of Curcuma zedoaria with alcohol extraction promoted the growth of the plant, but it was not conducive to the accumulation of organic matter. High concentration of Curcuma zedoaria with alcohol extraction delayed the growth of plant, but was beneficial to the accumulation of organic matter.
