黑老虎生物学及其观赏特性研究

Study on the Biological Characteristics of the Landscape Plant Kadsura Coccinea

研究黑老虎形态特征和生长发育特性,为野生资源保护、园林景观应用及规范种植提供指导.通过林间系统定点观察和普遍调查相结合的方法,进行黑老虎形态特征和生长发育特性的研究.老虎为多年生常绿攀援木质藤本植物,通过3余年观察结果表明,黑老虎年生长发育阶段过程具有明显的萌芽、快速生长、缓慢生长、休眠等规律,具体归纳为萌芽期每年的3～4月、快速生长期5～8月上旬、高温缓慢生长期8～9月,秋发期10～11月,低温休眠期12月至次年2月等五个时期;花期4～10月,果期6～12月,聚合果球形,幼果青色,熟时红色.为进一步研究、开发野生药用兼观赏植物提供参考.

To study the morphological characteristics and growth characteristics of Kadsura coccinea in landscape plants, and provide guidance for wild resources protection, landscape application and standardized planting.The morphological characteristics and growth and development characteristics of Kadsura coccinea were studied by the combination of frest system fixed point observation and general investigation.Kadsura coccinea is a perennial evergreen climbing woody vine.Through 3 years observation, results show that the growth and development process of Kadsura coccinea has obvious stages of germination, rapid growth,slow growth, dormancy consistent rule, such as five stages, that is, germination period from annual March to April, fast growth period from May to July, high temperature slow growth period from August to September,autumn period from October to November,athermobiosis from December to February; Flowers from April to October, fruit from June to December, fruit globose ,young fruit eyan ,ripe red.It provides theoretical basis for further study ,cultivation management and garden application, and provides refrenee for developing wiht medicinal and ornamental plants.
