【摘要】 [目的]为牛大力种子检验和种子质量标准的制定提供参考。[方法]分别进行不同种子处理在同一光照培养箱中的发芽试验和不同基质种子发芽试验,研究不同种子处理及河沙、赤红壤和石灰土等不同萌发基质对牛大力种子萌发的影响。[结果]清水浸种为较好的牛大力种子处理,种子平均发芽率达61.25%;其次为40℃水浸种,种子平均发芽率为59.75%;而磨伤后清水浸种,种子平均发芽率仅42.50%;不磨皮、不浸种的对照组种子平均发芽率仅35.50%。河沙为较好的牛大力种子萌发基质,播种后35d就开始发芽,种子平均发芽率达55.00%;其次为石灰土,播种后38d开始发芽,种子平均发芽率达43.50%;而赤红壤播种后40d陆续发芽,种子平均发芽率仅37.00%。[结论]牛大力种子直接用清水浸种处理后发芽效果较佳;用河沙作萌发基质可以得到较好的发芽效果。更多还原

【Abstract】 [Objective] The reference for the standard of Millettia speciosa Champ.seed quality and its evaluation was provided through the research.[Method] The experiment in the germination of Millettia speciosa Champ.seeds,treated with different method,in one incubator and in three kinds of matrixes:sand,red soil and lime soil,was conducted so that the effect of different treatment of seed and different matrix conditions on the germination of Millettia speciosa Champ.seed was analyzed.[Results] The Millettia speciosa Champ.seed soaked with clean water was the best one with the average rate of its germination of 61.25%;then,soaked with 40 ℃ clean water with the average rate of its germination of 59.75%;the seed broken and then soaked with clean water was the third one with the average rate of its germination of 42.50%,and the CK group(the seeds nonb-roken and non-soaked)was the worst one with the average rate of its germination of 35.50%.The sand was the best matrix with its germinating on the 35th day after its sowing and average rate of its germination of 55.00%;then,the lime soil,on the 38th day and 43.50%and the red soil was the last one with its germinating on the 40th day after its sowing and average rate of its germination of 37.00%.[Conclusion] The best efficiency on Millettia speciosa Champ.seed germination was come from the treatment of seed its seed soaked with clean water and cultured in sands.更多还原
