- 摘要:
- 对文冠果硬枝扦插苗生根根系形态特征进行定量分析，研究其根系总长度、根系总表面积、总体积等根系形态指标及其与IBA浓度变化的关系。结果表明：与清水对照（CK）相比较，IBA显著（P＜0.05)提高了插穗根系总根长、总表面积、总体积形态指标；随着IBA浓度的升高，根系各形态指标呈现先升高后降低的趋势，总根长和总表面积峰值均出现在IBA浓度为800 mg/L，且生根率达到了65.40%；经IBA处理的插穗生根根系主要分布在径级＞2.0 mm区间；根系总根长、总表面积、总体积与IBA浓度相关性均达到显著性水平。经回归分析，当IBA浓度保持在795～820 mg/L时，文冠果插穗可获得较高的根系形态指标。
- Abstract:
- The rooting morphology of the hardwood cuttings of Xanthoceras sorbifolia Bunge was quantitatively analyzed to investigate the root length，total root surface area，total volume，and the changes of the rooting morphology under different concentrations of IBA treatments.The results showed that,compared with the water control (CK)，IBA treatments significantly (P<0.05) increased total root length，total surface area，total volume.Indices of the root morphology increased firstly and decreased subsequently with the concentration of IBA increased，and the peak of the total root length，the total surface area and the total volume occurred at IBA concentration 800 mg/L，and rooting rate reached 65.40%.The roots of shoots of cutting with IBA treatments were mainly distributed in diameter classes>2.0 mm.There were significant correlation among the total root length，the total surface，the total volume and the concentration of IBA.Through regression analysis，the shoots for cutting of Xanthoceras sorbifolia obtained the higher root morphology when the concentration of IBA in 795～820 mg/L.
