湖南植物引种历史,现状和前景 总被引:1,自引:2,他引:1
对湖南省植物引种工作历史与现状做了概述,将湖南植物引种史划分为两个自然时期:即新中国成立之前的自发零星引种时期和新中国成立之后的组织批量引种时期后一时期又划分为3个阶段:盲目引种阶段、探索阶段、系统引种阶段。作者认识,通过百余年的植物引种实践,既积累了丰富的成功经验,在生产中产生了明显的经济效益;同时也得到了不少失败的教训?作者简析了成败原因,指出了弊端,提出建议并展望前景。 相似文献

浅议我国棕榈科观赏植物栽培应用现状与展望 总被引:7,自引:0,他引:7
一、回顾过去 成果卓著 1.建立了我国棕榈科植物科研生产基地。棕榈科植物主产于热带及亚热带地区,全科约有250属3500种,而我国仅产约20属70余种,主要分布于广东、广西、福建、海南、云南、台湾、及港澳地区。由于该科大部分种类喜温暖耐寒性差的特点,其主要栽培应用区域也集中在上述华南、西南各省份。栽培种类以引进国外种为主,挖掘本国野生种为辅。自五十年代以来,华南、西南几大植物园开始棕榈科植物引种栽培,成果卓著。 相似文献

Amazonian palms are prime candidates for sustainable management of non-timber forest products and yet useful species are often harvested destructively. This paper examines a promising management initiative for one of the most useful Amazonian palms – Mauritia flexuosa – in a rural community of northeastern Peru. Based on data from household surveys (n = 57), filmed in-depth interviews, focus groups and participant observation, we identify the factors that influence: (1) the adoption of a locally developed climbing device for wild-harvesting of aguaje palm fruit; (2) the continued practice by some households of palm felling for harvesting fruit; and, (3) investment by households in planting and cultivation of aguaje palm. Our findings identify key conditions for palm management and point to the particular importance of the adoption of palm-climbing devices, not only for reducing wild palm felling but also for stimulating broader community-level conservation as well as efforts to cultivate the palm. 相似文献

Robinia pseudoacacia 'Idaho' (Robinia×ambigua 'Idahoensis', R. pseudoacacia×R. viscosa) modified by a mtl-D gene went through five lines and had characteristics of drought tolerance. Three stages of their micropropagation had been studied by previous investigators. The other two stages, in vitro shoot rooting and plantlet acclimatization, still remained unsolved in the laboratory. For this paper, we studied the later two stages based on the previous achievements. Results showed that the highest rooting rate of Idaho locust was 98.4% when the in vitro shoots, over 2.5 cm in height and 0.08 cm in diameter, were placed on a half strength MS basal medium with 0.4 mg·L-1 IB A and 0.1 mg·L-1 NAA as supplements and were solidified with 0.5% agar; the highest survival rate was 98.3% when the rooted plantlets were potted in vermiculite. All the stages for micropropagation of the Idaho locust, modified by the mtl-D gene, were assembled completely. The tissue culture plants grow well in the field. 相似文献
