以越南抱茎茶(Camellia amplexicaulis(Pitard)Cohen Stuart)半木质化枝条为插穗材料进行扦插试验,研究了不同扦插基质、不同生长调节剂对越南抱茎茶扦插生根的影响。结果表明:以基质M1(100%赤红壤)插穗生根质量最好,其生根率、生根数量、根长最大,分别为80.31%、12.90条/穗、5.32cm,其次为M2(赤红壤∶草炭=2∶1),基质M3(赤红壤∶柳糠=2∶1)生根效果最差;5种生长调节剂中以组合型生长调节剂N1(IBA 1 000mg/L+NAA 200mg/L)处理的插穗生根效果最好,生根率和生根数量最大,分别为83.00%、14.00条/穗,N2(IBA1 000mg/L)次之。试验中插穗为愈伤生根型,即切口生根,未发现有皮部生根。 相似文献

以丰花月季品种"红帽子"为试材,选取生长健壮充实、无病虫害、品质优良的半木质化枝条作插穗,采用4因素3水平试验,研究基质(A)、生长素(B)、枝条部位(C)和扦插深度(D)对扦插繁殖效果的影响,以期为丰花月季种苗繁育提供理论依据及技术支撑。结果表明:基质、生长素、枝条部位和扦插深度等因素对生根率的影响顺序为A(基质)D(扦插深度)C(枝条部位)B(生长素);对生根数的影响顺序为A(基质)B(生长素)C(枝条部位)D(扦插深度);对根长的影响顺序为A(生长素)D(扦插深度)C(枝条部位)B(生长素)。丰花月季扦插的最佳组合为A_2B_2C_2D_1,即珍珠岩+IBA+中部枝条+扦插深度3cm,其生根率达75.79%;平均生根数7.12条;平均根长6.87cm。 相似文献

植物生长调节剂对酸枣扦插繁殖的影响 总被引:2,自引:0,他引:2
以酸枣为试材,进行不同植物生长调节剂和不同浓度处理的嫩枝扦插试验,研究3种植物生长调节剂对酸枣扦插繁殖的影响。结果表明:NAA、IAA的3000mg/L浓度速蘸效果为好,生根率分别达到74%和64%。酸枣进行嫩枝扦插,插穗类型平均生根率存在较大差异,枣头一次枝梢部平均生根率明显高于其它插穗类型,平均生根率为71.8%,枣头中基部插穗次之,平均生根率为45.3%,枣头二次枝平均生根率最低,平均生根率为42.6%。 相似文献

为了解决番茄实生苗育种周期长,高品质种子价格昂贵等问题,在扦插育苗中通过施用不同生长调节剂,调节处理时间、处理浓度,以缩短番茄育苗周期,提高幼苗品质,降低种苗成本。以番茄品种7558和劳拉的侧枝作为试验材料,研究在浓度为0、20、40、60、80、100mg/L的生根粉、吲哚乙酸、萘乙酸,分别处理10、20、30 min条件下番茄侧枝扦插的生长情况。结果表明:品种7558在生根粉、吲哚乙酸(IAA)、萘乙酸(NAA)分别为60 mg/L/30 min(处理浓度/处理时间)、80 mg/L/30 min、60 mg/L/10 min时,品种劳拉在生根粉、IAA、NAA分别为60 mg/L/30 min、100 mg/L/30 min、80 mg/L/10 min时生长状况较好,且不定根的发生情况较好,其中品种7558生长最好;从整体生长势和根系活力来看,萘乙酸对扦插苗生长的影响更显著,而生根粉的效果相对较弱。番茄扦插繁殖生产中,可优先选择萘乙酸进行侧枝处理。 相似文献

There was a positive correlation between shoot length and the proximal diameter of the prepared cutting in stockplant sources of Prunus insititia ‘Pixy’ that had different rooting potential. The precise relationship depended on source, with shoots from a severely pruned micropropagated source, and those developing from the trunks of various stock- plants, usually being thinner for any given length than normal distal cuttings from pruned and non-pruned conventional source stockplants. To a large extent rooting percentage, root numbers and root length increased between sources as the overall ratio of proximal stem diameter to shoot length decreased. Cuttings from the relatively thick, short shoots of the unpruned source were among the poorest rooting, while those from the relatively thin, long shoots from the trunk, and from the micropropagated source, rooted best. This between-source effect reflected the fact that within the less ready rooting sources there was also a negative correlation between the proximal diameter of the cutting and its rooting ability. This relationship was lost progressively as the rooting potential of sources increased, thus giving no opportunity for a trend to occur in the trunk-derived cuttings from the micropropagated source where virtually all cuttings rooted. 相似文献
