1. In order to obtain basic data on breding of tree peony, principal factor and cluster analysis were conducted. In result, main factor was closely related with flower stalk and leaf length. Cluster analysis showed that a hybrid cv. Gunpouden between cv. Hanadaijin and Kamadafuji belonged to the same cluster. Interspecific yellow cultivars differed clearly from the other cultivars. Chinese cultivar, Meijonohomare also distinguished from Japanes cultivars. 2. Forced flowering of eary late December was studied. Yield in 4-year-old plants with large roots was higher than that in 2-year-old plants with small roots. Floweing in late December was possible, using winter-blooming cutivar treated with low temperature. 3. Flower pigments in tree and herbaceous peony were peonidin-3-glusoside, peonidin3,5-glucoside, cyanidin-3-glucoside, cyanidin-3,5-glucoside, pelargonidin-3-glucoside and pelargonidin-3,5-glucoside.Flowers with deep color has many kinds of pigments. Clutiver classification of herbaceous peony was possible from difference of patterns in flavone and flavonoid. 4. Sprouting of Japanse cultivars were between May 1 and 5, while that of Chinese cultivars were late April. 5. Optimum temperature of pollen geramination in Japanese and Chinese cultivars 15ﾟC.6. Seeds were not obtained from cross between tree and hearbaceous peony.

1.为了获得牡丹育种的基础数据，进行了主因子和聚类分析，结果表明，主因子与花梗和叶长密切相关。和 Kamadafuji 属于同一簇，种间黄色品种与其他中国品种有明显区别，Meijonohare 也与日本品种有区别。研究表明，使用经过低温处理的冬季开花品种，12 月下旬开花的结果是，4 年生大根植物的产量高于 2 年生小根植物。 3. 乔木和草本牡丹中的花色素有芍药苷-3-葡萄糖苷、芍药苷-3,5-葡萄糖苷、花青素-3-葡萄糖苷、花青素-3,5-葡萄糖苷、天竺葵素-3-葡萄糖苷和天竺葵素-3,5-葡萄糖苷。颜色深的花有多种色素，可以根据黄酮和类黄酮4的模式差异对草本牡丹进行分类。日本品种的发芽时间为5月1日至5日，中国品种的发芽时间为4月下旬。 5.日本和中国品种的花粉萌发最适温度为15℃。6．未从乔木与芍药杂交获得种子。
