| 摘 要： | 总结引种洛阳后萌发较晚的紫斑牡丹茎叶生长规律情况,结果表明,萌发期为3月上旬;7个品种紫斑牡丹的茎高、叶长和叶宽年平均生长量存在差异,表现出植株高矮和叶片大小的不同,但各指标的变化趋势基本一致。物候期比原产地提前30天。茎高生长起始时间早,速生期短,生长集中;叶生长的持续时间相对要长;叶宽生长的结束期更迟于叶长。3月12日-4月16日为这些紫斑牡丹茎生长高峰期,平均茎高生长量达23.56 cm;4月24日已完成茎高全年生长量,年平均生长量为23.99 cm。从3月下旬至4月中旬是叶片的迅速生长期,4月16日叶片大小定形,平均叶长、叶宽分别达到28.16 cm和23.80 cm。花期集中在4月16-26日,培育晚开新品种有重要意义。

| Abstract: | The stem and leaves growth rhythm of Paeonia rockii which germinates late after introduced to Luoyang Region was concluded. The results showed that the germination period occurs in early March. And the 7 varieties of P. rockii show the yearly differences in stem height, leaf length and leaf width, which are reflected in different heights and leaf size, but the changes of different index remain basically the same. The phenophase is 30 d earlier than that in the original place. Stem height grows early but for a short period with concentrated growth. Leaf has longer time to grow, and the growth of leaf width ends late than the growth of leaf length. These P. rockii growth comes to the peak during 12th March to 16th April, with the average stem growth being 23. 56 cm. Annual growth of stem comes to the end at 24th April, with the average stem height growth of 23. 99 cm. Leaves enter the rapid growth from late March and middle April, with the annual average growth being Different stem height growth starting time, and the final size of leaves is formed at 16th April, with average leaf length and leaf width being 18. 16 cm and 23. 80 cm, respectively. Florescence concentrates in 16th-26th April. It is importantly significant to cultivate new varieties. |
