| 摘 要： | 对重庆南山植物园展览温室引种的160科（近1 000种）植物进行了度夏适应性调查及生态因子分析。结果表明：引种植物适应性好的（Ⅰ、Ⅱ级）为124科（77.5%）;适应性一般的（Ⅲ级）为21科（13.1%）,明显不适应的（Ⅳ、Ⅴ级）为15科（9.4%）。引种植物大多数是热带分布型和温带分布型。分析结果表明,影响展览温室植物度夏适应性的因素主要与植物的原产地、温室内的环境因子、植物群落结构配置有关。在引种时,须充分认识迁出地与迁入地环境条件的差异,改善迁入地的环境条件。该研究结果可为温室植物的成功迁地保护提供科学依据。

| Abstract: | The summer adaptability of the introduced 160 families(about 1 000 species) of plant in the exhibition greenhouse of Chongqing Nanshan Botanical Garden were investigated and their ecological factors were analyzed.As indicated by the results,124 families(77.5 %) adapted well and belonged toⅠand Ⅱ grades;21 families(13.1%)adapted averagely and belonged to Ⅲ grades;15 families(9.4%) obviously could not adapt and belonged to Ⅳ and Ⅴ grades.Most of the introduced plants in the exhibition greenhouse were distributed in the tropical and temperate areas.The analysis results showed that the summer adaptability of the plants in the greenhouse was mainly influenced by its place of origin,the environmental factors in the greenhouse and the structure of plant community.The introduction of the plants should take full into account the difference between the environmental conditions of the out-introducing places and in-introducing place,and improve the environmental conditions of the in-introducing place.The study results provided scientific basis for the successful protection of the ex-situ greenhouse plants. |
