摘　　要：以一品红 ( Euphorbia pulcherrima)品种‘自由红色’( Freedom Red)、‘自由白色’( Freedom White)为试材 ,研究了采穗对母本苗所产盆花品质的影响。结果表明开花时一品红母本苗所产盆花的株高、冠幅、最大花径、枝长、节数、节长和有效枝百分率都高于只摘去顶端生长点的对照 ,表明采穗不会降低一品红盆花的观赏品质。自繁扦插苗所产盆花的品质与购买苗差异不大 ,表明自繁扦插苗是可行的 ;不足之处是分杈严重。The effect of harvesting cuttings on the pot flower quality of mother plants were studied in Freedom Red and Freedom White poinsettia (Euphorbia pulcherrima Willd.).Plants were pinched in one of the two ways:① Removal of the apical meristems plus 2～3 full expanded leaves and could be used as a cutting;② Removal of the apical meristem plus all immature leaves with petiole remained.The results showed that harvesting cuttings did not reduce the visual quality of pot flower produced by mother plants with higher plant,bigger canopy and inflorescence diameter,longer shoot and node,more node and higher percentage of effective shoot.Self-propagated plantlets produced pot flowers of equal quality compared to purchased plantlets.So it is possible to produce plantlets by cutting.But the percentage of splitting was more than 50% in self-propagated cuttings.The mechanism of pinching position on visual quality and the splitting of self-propagated plantlets were discussed in relation to axillary bud sprouting and ontogenetic age,respectively.
