英语翻译
To test the nose,the team presented it with healthy leaves from cucumber,pepper and tomato plants,all common greenhouse crops.Then the scientists collected samples of air around damaged leaves from each type of crop.These plants had been damaged by insects,or by scientists who made holes in the leaves with a hole punch (打孔器).ks5u
The e-nose,it turns out,could identify healthy cucumber,pepper and tomato plants based on the volatile compounds they produce.It could also identify tomato leaves that had been damaged.But even more impressive,the device could tell which type of damage – by insects or with a hole punch – had been done to the tomato leaves.ks5u
With some fine tuning,a device like the e-nose could one day be used in greenhouses to quickly spot harmful bugs,the researchers say.A.device like this could also be used to identify fruits that are perfectly ripe and ready to pick and eat,says Natalia Dudareve,a biochemist at Purdue University in West Lafayette,Ind.who studies smells of flowers and plants.Hopefully,scientists believe,the device could bring large benefits to greenhouse managers in the near future.ks5u

为了测试电子嗅觉器,小组人员给其提供的全部是平常的绿色蔬菜叶子,如黄瓜叶、辣椒叶、西红柿叶.然后科学家从每种植物已损坏的叶子周围采集气体样本.这些植物或被昆虫叮咬,或人为地用打孔器打上孔.
测试结果表明,电子嗅觉器通过这些植物所散发出来的化合物可以分辨健康的黄瓜、辣椒和西红柿.它同样可以分辨出损坏了的西红柿.更让人惊奇的是,电子嗅觉器可以说出西红柿相应的损坏方式——是由于昆虫还是人为的.
研究人员说,通过适当的调整(改进),类似于电子嗅觉器的装置将被应用于温室以快速确定害虫的位置.来自印度西拉斐特普敦大学研究植物和花朵气味的生物化学家纳塔利娅杜拉利维说“类似的装置可以用来判断水果是否成熟,以便适时采摘、食用.”科学家们满怀希望相信在不久的将来该设备可以给温室种植户带来很大的利益.
