摘　　要：为了较为科学合理的进行油茶种植,提高油茶产量,研究了江西11个油茶高产无性系的花期、花粉生活力及杂交组合坐果情况和种子含油率。结果表明:①通过花期观察,确定赣55、赣无1、赣无2、赣无16和赣无24花期基本一致。②11个油茶高产无性系的花粉生活力均达到50%以上,在油茶种植配置上花粉活力不会成为油茶高产的限制因子。③通过比较分析杂交组合坐果情况和种子含油率,确定赣无1、赣无16、赣无2、赣无11、赣55、赣190和赣无8混栽为科学合理的配置模式。④综合考虑11个油茶高产无性系的花期、花粉生活力及授粉组合坐果情况和种子含油率,以赣55、赣无1、赣无2和赣无16为主栽品种进行油茶种植,是最佳的配置模式。In order to cultivate Camellia oleifera more scientifically and rationally and improve its yield, the florescence, pollen viability, fruit setting and seed oil content of cross combination of the eleven high-yield clones of C. oleifera were studied. The results showed that： The florescence of G55, GW1, GW2, GW16 and GW24 were basically identical by florescence observation; the pollen viability of eleven high-yield clones of C. oleifera were all above 50%, which will not be the limiting factor of C. oleifera high yield in the planting allocation; the mixed planting of GWI, GW16, GW2, GWll, G190 and GW8 were scientific and reasonable allocation model through the comparative analysis of fruit setting and seed oil content of cross combination; by comprehensive consideration of florescence, pollen viability, fruit setting and seed oil content of cross combination of the eleven high-yield clones of C. oleifera, the C. oleifera planting of using G55, GW1, GW2 and GW16 as main cultivars were the best allocation model.
