天然香料，商机无限

我国香料植物品种繁多，热带植物品种尤为丰富，但多数品种因生产周期长、见效慢，均没得到良好的发展。目前一个从外国引进的香料品种落户在吉林公主岭市特种植物示范园并试种成功。该品种为一年生草本香料植物。不受南北区域限制，适合我国大部分地区种植。表现为生产周期短，对土质要求不严，抗干旱、耐瘠薄，对气候适应性极强等特点，是大力发展的香     

生物燃料的类型划分

生物燃料主要包括由玉米和甘蔗、秸秆制造的燃料乙醇、生物柴油、由纤维素制造的燃料乙醇以及其它生物燃料，因此甘蔗是一种高产量的热带植物，在茎部积累了大量的蔗糖；玉米是美国产量最大的农作物，2005年总产量约2.82亿t,玉米种子中约60％为淀粉。     

Investigation of natural VOC emitted from tropical vegetations in China

Twenty-three kinds of typical plants in Xishuangbanna, the tropical area of southwestern China, were screened to estimate the emission rates of isoprene and monoterpenes by adopting bag-enclosure and curette sampling methods followed by a GC-FID analysis. It was found that the Ficus species were mainly emitting isoprene and most tropical vegetations were mainly releasing monoterpenes. The results also showed that the emissions of isoprene were affected by both temperature and PAR( Photosynthetic Active Radiation), while monoterpene emissions were mainly temperature-dependent.     

修复生态的神奇之草

10月6日，第三届国际香根草大会在广州隆重召开，来自28个国家和地区的300多位代表与会，泰王国诗琳通公主、中科院副院长陈竺、广东省副省长宋海分别在开幕式上致辞。人们也许会感到奇怪，香根草究竟是何方神圣?区区一种小草怎么会受到国际政要和学术界的青睐?现在，让我们来看看这种草的神奇之处吧。
