Introduction And Propagation Of Cut-flower Cultivars In Herbaceous Peony

Herbaceous peony(Paeonia lactiflora.) is a traditional plant native to China.The herbaceous peony is popular as cutting-flower with straight peduncle,elegant flower pattern,and long florescence.The herbaceous peonies have high ornamental value and wide prospect of market both at home and in the international.Herbaceous peony cut-flower cultivars were introduced to Beijing from Netherlands,their biology habits and ornamental values were researched.We have got the first-hand data of the new group, which will be beneficial to coming commercial production and popularization.The results showed that.1,13 cut-flower cultivars were introduced.They can grow and bloom normaly in Beijing without any special maintenance.They appeared strong diseases resistance,high ornamental value,which are good cut-flower advantages.So it is feasible to introduce them into the zone which have similar climate to Beijing.2,Most cultivars are excellent cut-flower varieties with beautiful flower,straight stem which are good cut-flower traits.The introduced herbaceous peony cut-flower cultivars will rich domestic market,which have very wide prospect of market and breeding application value.3,The greastest cultivars are 'Pink Hawaiian coral'and'Kansas' by cut-flower evaluation.4,Crown division was the most used way to propagate intersectional herbaceous peonies,which can get high livability,near 100%.5,The result of root cutting reprofuction show that root cutting reprofuction is a efficient path for improve peony propagation coefficient,and there are significant differences between different varieties in root cutting reprofuction survival.
