This fascinating experiment showed that plants not only detect and react to specific wavelengths of light, plants can also detect and react to changes in the ratio of one wavelength to another.
这个有趣的实验表明，植物不仅能探测和对特定波长的光产生反应，还能探测不同波长比率的变化并对其做出反应。
But when the ratio became 3:4 (9 versus 12), the fish showed no indication that they could detect a difference.
但是当比率变为3：4(9对12)，没有迹象表明它们察觉到不同。
