Abstract

Keywords

To investigate the effects of substrate，cutting type，and cultivar on the cutting propagation of Bougainvillea spp.， this study selected woody and semi-woody cuttings from three cultivars as experimental materials.Five types of substrates were chosen for the cutting experiments： commercial potting mix， rock wool， coconut coir， sandy soil，and peat soil. ForB.spectabilis‘Splendens’，the germinationrate of woody cuttingswas 6.67% inrock wool and 0% inother substrates; the rooting rate was 0% acrossallsubstrates.For B. glabra ‘Elizabeth Angus’，woody cuttings achieved the highest germination rate in peat soil and rock wool （93.33%） and the highest rooting rate in rock wool and coconut coir （80%） .For B. glabra‘Sao paulo’，semi-woody cuttings showed higher germination rates than woody cuttings except in potting mix，with the highest rooting rates in potting mix （93.33%） . The germination rate of Bougainvilla spp.cuttings isdetermined bycultivar characteristics， cutting type，and substrate selection.Notably，B.spectabilis‘Splendens’is unsuitable for cuttingpropagation，whereasB.glabra‘Elizabeth Angus’and B.glabra‘Sao paulo’can be successfully propagated using appropriate substrate selections.

文章亮点

1）从基质类型、品种差异、插穗类型3个角度综合分析了三角梅的扦插繁殖潜力；2）筛选了不同品种不同插穗类型适合的扦插基质类型，为行业生产及应用提供参考；3）通过探究不同品种的扦插繁殖特性，得出“毛叶紫’不适合扦插繁殖的结论，一定程度上驳斥了三角梅无性繁殖存活率高的理论，其扦插存活率存在品种差异。（剩余8084字）
