【摘要】 在大田和大棚两种试验条件下,采用完全随机区组试验设计,研究了生长素处理、插穗规格等因素对红花刺槐根段的插根繁殖的影响,并且对大棚扦插的红花刺槐测定乙烯释放量。试验结果表明,根段长度对生根影响不大,粗度表现为较粗的效果好,生长素处理以稀土50 mmol/L效果最好,乙烯释放量较大的根段出苗率也相对较高。有些不适当的生长素处理则表现为抑制作用。更多还原

【Abstract】 The effects of different auxin treatments and cutting standards on the root reproduction of the root section for Robinia pseudoacacia var. decaisneana were studied in the fields and the plastic shelters, and the emission of ethane for Robinia pseudoacacia var. decaisneana was determined. The result showed that the root length of cuttings had little effect on rooting, the cuttings with larger diameters were better, and the treatment with 50 mmol/L of rare earth was the best. The sprouting rates of those root sections with larger emission of ethane were relatively higher. Some inadequacy auxin treatments showed inhibitory effects.更多还原
