Twelve anthocyanins （1-12） were isolated from the red flowers of camellia hongkongensis Seem. by chromatography using open columns. Their structures were elucidated on the basis of spectroscopic analyses, that is, proton-nuclear magnetic resonance, carbon 13-nuclear magnetic resonance, heteronuclear multiple quantum correlation, heteronuclear multiple bond correlation, high resolution electrospray ionization mass and ultraviolet visible spectroscopies. Out of these anthocyanins, a novel acylated anthocyanin, cyanidin 3-O-（6-O-（Z）-p-coumaroyl）-β-galactopyranoside （6）, two known acylated anthocyanins, cyanidin 3-O-（6-O-（E）-p-coumaroyl）-β-galactopyranoside （7） and cyanidin 3-O-（6-O-（E）-caffeoyl）-^- galactopyranoside （8）, and three known delphinidin glycosides （10-12） were for the first time isolated from the genus camellia. Furthermore, pigment components in C. japonica L., C. chekiangoleosa Hu and C. semiserrata Chi were studied. The results indicated that the distribution of anthocyanins was differed among these species. Delphinidin glycoside was only detected in the flowers of C. hongkongensis, which is a special and important species in the section camellia. Based on the characterization of anthocyanins in the section camellia species, there is a close relationship among these species, and C. hongkongensis might be an important parent for creating new cultivars with bluish flower color.

对福建种源及广西区内100个山茶花(camellia japonica)品种进行种质收集,通过相同造林技术管理,调查成活率、保存率,分析其种质收集技术,以及对干热河谷气候的适应性。结果表明,100个山茶花品种平均成活率为84.1%,保存率64.5%,大部分树种能正常生长开花,能完成种质收集和实现其观赏研究价值。同时,对成活率和保存率在90%以上的27个适应较强的品种进行年生长量、开花情况分析,结果显示,‘烈香’‘东方亮’在27个优势种中生长最为优越,其次是黄的旋律;27个山茶花品种间生长量存在着极显著差异(P<0.01)。

本文研究0%、50%、70%、90%等4种遮阳率处理15个月时对2个山茶(camellia japonica)品种‘赤丹’(‘Chidan’)与‘迪斯’(‘Dees’)的生长增量、生物量、叶绿素、光合特性等指标的影响。研究发现:‘迪斯’各项生长和光合指标随着遮阳率上升呈现下降趋势,全光照处理时‘迪斯’生长增量、生物量、叶绿素SPAD值、净光合速率(Pn)、蒸腾速率(Tr)、气孔导度(Gs)和胞间CO_(2)浓度(Ci)等各项光合特性指标值均显著优于其他处理。‘赤丹’在50%遮阳率处理时生长增量和生物量达到最大值,其次是全光照,70%和90%遮阳率处理时最差;光合指标随着遮阳率增长呈先降后升趋势。结果表明,‘迪斯’适宜全光照环境下生长,‘赤丹’则适宜半阴环境下生长。
