摘要：文心兰为文心兰属（Oncidium Sw.）植物的总称,为世界四大观赏洋兰之一,原产于墨西哥、巴西和牙买加等热带和亚热带地区,全属约有400个野生种[1],目前已有70余种被引种栽培,并培育出大量的杂交品种.香水文心兰（Oncidium SharryBaby‘Sweet Fragrance’）在花盛开时具有浓郁的巧克力香味[2-3],且可四季开花,观赏价值较高.
In order to investigate the effect of light on flower aroma of Oncidium Sw., flower aromatic components and relative contents of Oncidium Sharry Baby ‘Sweet Fragrance’ at full flowering stage under illumination intensity of 1 510,2 170, and 3 240 lx conditions were detected and compared by GC-MS technology. The results show that under illuminationintensity of 1 510, 2 170, and 3 240 lx conditions, there are obvious differences in flower aromatic components and relative contents, but relative content of ocimene is the highest. There are 36, 43, and 35 kinds of flower aromatic components under illumination intensity of 1 510, 2 170, and 3 240 lx conditions, respectively; in addition, relative contents of mostflower aromatic components are the highest under illumination intensity of 2 170 lx condition, but are the lowest underillumination intensity of 1 510 lx condition. Sensory evaluation result shows that flower aroma concentration index isrelatively small under no light and weak light conditions, but relatively large under strong light condition. It is suggested that there is an obvious effect of light on flower aroma of Oncidium Sharry Baby ‘Sweet Fragrance’, in which, number and relative contents of flower aromatic components are basically the highest under illumination intensity of 2 170 lx condition.
