项目摘要

Based on major factors of flowering, Higuchi et al. (1993) categorized ornamental plants into three types, namely, Photoperiodicity-, thermoperiodicity-, and vegetative reproductive growth periodicity-type (VR). This categorization is outstanding and able to classify various ornamental plants according to the developmental phases and flower-inducing factors. There are a large number of published works about growth habits and flowering control of ornamental plants, however, most of them are not useful for Higuchi et al. ' s categorization because of lacking data on developmental phases.Our studies added several ornamental plants to Higuchi et al.' s categories and also showed that their categorization did not cover the following plants: (1) Anemone (No qualitative requirements for germination, flower bud differentiation and flowering. Low temperature of 10℃ for 4-5 weeks increased the number of cut flowers and improved flower quality) ; (2) Madagascar jasmine (Flower bud differentiation … More was stimulated by intermediate temperature, but inhibited by high temperature. Flower bud development was stimulated at high temperature. At low temperature it was inhibited by long days, and strongly inhibited by short days. A day-neutral plant) ; (3) Sucuteraria baicalensis (No qualitative requirements of photoperiod and temperature for flower bud differentiation and flowering) ; (4) Heliopsis helianthoides (No requirements of temperature for flower bud differentiation and flowering. A qualitative long-day plant) ; and (5) Campanula lactiflora (No qualitative low temperature requirements for flower bud differentiation and flowering. A qualitative long-day plant).Takeda (1999) has proposed different and more easily applicable categorization to practical culture, Which is based on the responses of ornamental plants to the environment rather than on the developmental phases chageable with environmental conditions. In his categorization ornamental plants are grouped by the vegetative growth periods, flowering times, and effects of temperature and photoperiod on flowering.In any case, the definition of technical terms such as vernalization and dormancy is prerequisite to categorize ornamental plants.

Higuchi等（1993）根据开花的主要因素将观赏植物分为光周期型、热周期型和营养生殖生长型（VR）。该分类法具有突出的特点，能够根据不同的观赏植物的发育阶段和开花诱导因素进行分类。关于观赏植物的生长习性和开花调控的研究已有大量发表，但由于缺乏发育阶段的数据，大多数研究成果对Higuchi等人的分类方法没有帮助。（1）银莲花（Anemone）（对发芽、花芽分化和开花无质量要求）。10℃低温处理4-5周，可增加切花数量，提高花品质）;（2）马达加斯加茉莉（花芽分化 ...更多信息中温刺激，高温抑制。高温促进了花芽的发育。在低温条件下，长日照抑制，短日照强烈抑制。白天中性植物）;（4）向日葵（Heliopsis helianthoides）（对花芽分化和开花无温度要求）。（5）乳花风铃草（Campanula lactiflora）对花芽分化和开花无质的低温要求。Takeda（1999）提出了不同的、更容易适用于实际栽培的分类方法，这种方法是基于观赏植物对环境的反应，而不是基于可随环境条件变化的发育阶段。在他的分类中，观赏植物是根据营养生长期、开花时间以及温度和光周期对开花的影响来分类的。在任何情况下，诸如春化和休眠之类的技术术语的定义都是对观赏植物进行分类的先决条件。少
