摘　　要：对2004年从甘肃兰州引进的7个紫斑牡丹品种在黑龙江省森林植物园内进行了引种试验。结果表明:不同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,但各指标的生长趋势基本一致。物候期比原产地延后30d。茎高生长起始时间早,速生期短,生长集中;而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。An experiment was conducted to study the growth rhythm of seven varieties of Paeonia rockii introduced from Lanzhou, Gansu Province to Heilongjiang Forest Botanical Garden in 2004. Results showed that there were some differences in average annual increments of stem height, leaf length and leaf width of different varieties judged from the various plant heights and leaf areas, but the growth tendencies of all the indexes were similar. Phenological stage was postponed for about 30 days. The initial growth of stem was earlier than that of leaf, but its fast-growing period was brief. The growth period of leaf was longer than that of stem. The growth stopping period of leaf width was later than that of leaf length.
