- 摘要:
- 为研究影响‘河津’樱扦插生根的主要因素,采用9种基质配比、10种激素浓度配比、3种不同部位的插穗,以及不同的扦插时间对‘河津’樱进行扦插繁殖试验。结果表明,不同的基质配比能显著影响插穗的生根率和生根数量,影响力大小依次为草炭>珍珠岩>椰糠,最佳基质配方为珍珠岩∶草炭∶椰糠10∶4∶2;植物激素IBA能有效提高‘河津’樱扦插生根率,随着IBA浓度的增加生根率呈现先增后减的趋势,其最佳浓度为3 000 mg·L-1;在相同处理条件下枝条中段部分的扦插生根率最高,优于下段和上段;‘河津’樱最适宜的扦插繁殖时间在6月下旬。
- Abstract:
- In order to study the main factors affecting the rooting of Cerasus campanulata×kanzakura ‘Kawazu-zakura’ cuttings, 9 kinds of substrates, 10 kinds of hormone concentrations and 3 kinds of cuttings from different parts were used, and different cutting time to C. campanulata × kanzakura ‘Kawazu-zakura’ cuttage propagation experiment. The results showed that the rooting rate and rooting quantity of cuttings were significantly affected by different matrix ratio. The order of influence was peat> perlite> coco bran, and the best matrix formula was perlite: peat: coconut bran 10∶4∶2; IBA could effectively increase the rooting rate of C. campanulata×kanzakura ‘Kawazu-zakura’ cuttings. With the increase of concentration, the rooting rate showed the trend of increasing first and then decreasing, the optimum concentration was 3 000 mg·L-1, and the rooting rate of the middle part of the branch was better than the lower and upper parts under the same treatment conditions. The optimum time for cuttage propagation was in late June.
