摘　　要：以牡丹单瓣品种‘凤丹白’、重瓣品种‘洛阳红’和‘玉楼点翠’为试验材料,研究其开花及衰老过程中叶片和花瓣的碳水化合物含量变化规律。研究结果表明:在整个开花过程中,3种牡丹花瓣可溶性糖含量呈前期上升后期下降趋势,而淀粉含量则逐渐降解;由于受生殖抑制的影响,叶片中碳水化合物也发生一定的变化,但不同品种牡丹碳水化合物变化略有不同,说明碳水化合物在牡丹花开放和衰老过程中具有重要作用。Using single petal tree peony variety ‘Fengdanbai’,double petal varieties ‘Luoyanghong’ and ‘Yuloudiancui’ as test materials,the carbohydrates change rule was studied during the blossom and senescence of petals and leaves.The results showed that in the whole process of blossom,the soluble sugar contents of these three kinds of tree peony petals increase earlier and drop later,while strach content is gradually degraded.For reproductive inhibiting,carbohydrate in leaf also has certain change,but different kinds of tree peonys change different.The results suggested that carbohydrates play an important role in the blossom and senescence of tree peony.
