通过实地调查,对厦门地区冬季观果和观花园林植物进行统计,分析其生活型、观赏特征、色彩和应用频度。结果表明,厦门冬季具有观赏价值的观果植物有20科22属25种(含种下等级),观花植物有33科51属63种(含种下等级)。厦门冬季观果植物以常绿乔木、灌木为主,果色以红色系为主,高应用频率的观果植物优势不明显;观花植物以乔木为主,花色以红色系、黄色系为主,高应用频率的观花植物优势明显,开花呈衬式花相的种类占多数。厦门冬季观果与观花植物资源较为丰富,但冬季表现较好的观果种类较少,而一些表现较好的植物未普遍应用,植物景观营造不合理,针对此问题提出改善厦门冬季植物配置的建议。  相似文献

为了解睡莲属(Nymphaea)植物开花的日变化规律,以广州华南农业大学湿地公园的睡莲属植物为对象进行观察和分析。结果显示,晚上开花类的热带睡莲,其日变化是花朵于晚上开放并持续至第二天上午,白天开花类的热带睡莲和耐寒睡莲,其开放时间为白昼,开放时间因种类不同而有所差异。白天开花的热带睡莲‘独立’(Nymphaea‘Independence’)和耐寒睡莲‘科罗拉多’(Nymphaea‘Colorado’)单朵花期3~4 d,耐寒睡莲墨西哥黄睡莲(N.mexicana)单朵花期2 d,雌雄蕊先后成熟以达到异花授粉的目的,单朵睡莲开放期间雄蕊群呈现不同形态。‘独立’睡莲呈现日出而开,日落则合的开花生物钟,10月至12月,光照时间缩短导致‘独立’睡莲开闭节律缩短。观察结果可为园林水景中睡莲属植物配置提供准确的数据支持。  相似文献

Aims In recent years, intercropping system has become one of the major practice of peanut (Arachis hypogaea) cultivation in northern China because of the high land and energy utilization efficiency, to some extent compensating for the production loss caused by decreasing area of cultivation land. Intercropped peanut plants often have a lower pod yield compared with monoculture due to constraint on light availability. This study was conducted to explore the shade-tolerance mechanism in two peanut cultivars, ‘Huayu 22’ and ‘Baisha 1016’, that grew in an intercropping system, by studying chloroplast ultrastructure and rubisco activity under different levels of shading.
Methods A field experiment was conducted with three levels of light treatments, including full natural light (CK), 50% natural light indensity (NLI), and 15% NLI. The ‘Huayu 22’ was used as a shade-tolerant cultivar and the ‘Baisha 1016’ as a shade-susceptible cultivar based on previous studies. Experimental plants of both cultivars were shaded for 40 days from emergency in 2006. Rubisco activity, the number and shapes of chloroplasts and starch grains, and number of grana and granum lamella were investigated in functional leaves of plants in all treatments.
Important findings The functional leaves of peanut plants in the 50% and 15% NLI treatments had a lower rubisco activity than those in the CK treatment. In the ‘Baisha 1016’, the reduction in rubisco activity was 40.1% in the 50% NLI treatment and 59.4% in the 15% NLI treatment, respectively, compared to the CK treatment;whereas no significant differences were found among treatments in the ‘Huayu 22’ in the rubisco activity. Compared with the CK, the number of chloroplasts remained unchanged, the number of grana and lamella in grana increased, and the individual chloroplast was longer and in perfect development in the functional leaves of plants of the ‘Huayu 22’ grown in the 50% NLI treatment. In contrast, the number of chloroplasts, grana and starch grains of the ‘Huayu 22’ plants decreased significantly, the chloroplast membrane and grana lamella were damaged, the number of granum lamella increased, and the individual chloroplast became longer in the 15% NLI treatment. The number and ultrastructure of chloroplasts in the ‘Baisha 1016’ plants followed similar patterns of changes as those of the ‘Huayu 22’ in the 50% NLI treatment. For plants of the ‘Baisha 1016’ in the 15% NLI treatment, their chloroplasts became more roundly shaped, with decreasing number of grana lamella and increasing number of starch grains, compared with the CK. There were a greater decrease in the grana number and more damage in the grana lamella in plants of the ‘Baisha 1016’ than those of the ‘Huayu 22’. In conclusion, the shade tolerance of the ‘Huayu 22’ resulted from lack of changes in rubisco activity and less damage in the ultrastructure of chloroplasts when under low light stress compared with the ‘Baisha 1016’.  相似文献

After analysis, statistics and conclude 1175 species (variety) of plants,1370 Dai names and 1691 meanings were obtained to elucidate how the Dai people recognize and define the plant. They used ‘hong e bin’, which means‘the things with life come out from the ground’ to define the plant. This is similar to the modern science which defined the plant as ‘anything that grows from the ground’. This is a highly synthesized scientific term that seldom seen in many other ethnics in the world. In their method of naming plants, they used the types of plant life form and economic type for ‘generic’ names, and used the meanings of plant morphogenesis and characters, economic uses, ecological distribution, and stories and legends etc. for ‘specific’ names. Among the 1691 meanings, they are occupied 60%, 30%, 8% and 2% respectively. This reflected that the naming method of Dai for plant ‘Just see what′s looking alike on naming them’ is similar to Linnaeus′ bi nomenclature of the modern botanical taxonomy. Moreover, the folk plant classification system based on the structure of Dai names is then established, including 5 categories as plant kingdom, tow ‘families’ of wild or cultivated plant, about 20 ‘genera’ of life forms and economic types, and more than 3000 species and over 1000 varieties, by the ‘two names’ in the paper as well.  相似文献

In introduced organisms, dispersal propensity is expected to increase during range expansion. This prediction is based on the assumption that phenotypic plasticity is low compared to genetic diversity, and an increase in dispersal can be counteracted by the Allee effect. Empirical evidence in support of these hypotheses is however lacking. The present study tested for evidence of differentiation in dispersal‐related traits and the Allee effect in the wind‐dispersed invasive Senecio inaequidens (Asteraceae). We collected capitula from individuals in ten field populations, along an invasion route including the original introduction site in southern France. In addition, we conducted a common garden experiment from field‐collected seeds and obtained capitula from individuals representing the same ten field populations. We analysed phenotypic variation in dispersal traits between field and common garden environments as a function of the distance between populations and the introduction site. Our results revealed low levels of phenotypic differentiation among populations. However, significant clinal variation in dispersal traits was demonstrated in common garden plants representing the invasion route. In field populations, similar trends in dispersal‐related traits and evidence of an Allee effect were not detected. In part, our results supported expectations of increased dispersal capacity with range expansion, and emphasized the contribution of phenotypic plasticity under natural conditions.  相似文献
