Abstract:
Taking ‘Jinling’，‘Zhongshan’ and ‘Yuhua’ series of 15 Dendranthema morifolium varieties as materials，series of freezing injury of the petals and leaves of Dendranthema morifolium,the recovery number of emergent rhizomes were compared and studied,and the cold hardiness was evaluated，in order to screen out the cold hardiness and suitable for the northeast area the application of Dendranthema morifolium.The results showed that the strongest cold hardiness of petals was the varieties ‘Yuhua’，then the ‘Zhongshan’ and the ‘Jinling’ was worst.There was no difference in the cold hardiness of leaves among them.The number of the emergent rhizomes of the varieties ‘Yuhua’ was the most than the varieties ‘Zhongshan’ and ‘Jinling’，which of the varieties ‘Jinling’ was the lest.
