以八仙花(Hydrangea macrophylla)不同品种的杂交种及银边绣球(Hydrangea macrophylla)与圆锥绣球(Hydrangea paniculata)杂交种为材料,利用胚培养对具有杂交障碍的组合进行胚抢救。结果表明:银边绣球(Hydrangea macrophylla)不同品种的杂交种在胚获得数、胚发芽率均存在较大差异;银边绣球(Hydrangea macrophylla)×圆锥绣球(Hydrangea panicu-lata)杂交种绝大多数胚发育不良;利用胚培养对杂交种进行胚抢救,是克服杂交障碍、获得杂交后代的有效措施。
Embryo culture was used to rescue embryos with crossbreed hybrids from Hydrangea macrophylla hybrids and Hydrangea macrophylla and Hydrangea paniculata hybrids. The results showed that there were significant differences in embryo germination percentage and embryo germination rate among different varieties of Hydrangea macrophylla hybrids. Most Hydrangea macrophylla × Hydrangea panicu-lata hybrids, Embryonic hypoplasia; Embryo culture hybrid embryos rescue, is to overcome the barriers to hybridization, access to hybrid progeny of effective measures.
