Studies on the establishment of year-round production systems by categorizing ornamental plants based on the growth habits and eco-physiological characteristics

根据开花的主要因素，Higuchi et al.(1993)将观赏植物分为光周期、热周期和营养生殖生长周期(VR)三种类型。这种分类是突出的，能够根据不同的发育阶段和开花因素对各种观赏植物进行分类。关于观赏植物的生长习性和开花控制的研究成果很多，但对于Higuchi等人来说，这些著作大多是不实用的。‘由于缺乏发育阶段的数据，S进行了分类。我们的研究增加了几种观赏植物。S的分类，也表明它们的分类不包括以下植物：(1)银莲花(对萌发、花芽分化和开花没有质量要求。低温10℃处理4-5周可增加切花数量，改善花质)；(2)马达加斯加茉莉花(花芽分化…MUX受中温刺激，但受高温抑制。高温对花芽发育有促进作用。低温下受长日照抑制，短日照抑制较强。花芽分化和开花对光周期和温度没有质量要求；(4)向日葵对花芽分化和开花没有温度要求。(5)乳花风铃(对花芽分化和开花没有质量低温要求)。武田(1999)对实用栽培提出了不同的、更容易适用的分类，这种分类是基于观赏植物对环境的反应，而不是基于随环境条件变化的发育阶段。在他的分类中，观赏植物按营养生长期、开花时间以及温度和光周期对开花的影响进行分类。无论如何，春化和休眠等术语的定义是对观赏植物进行分类的前提。较少

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.
