For the past decade, he has used the phototropic properties of cyanobacteria to produce images in Petri dishes.
The record (Fig. 127) shows that the phototropic effect increases with the directive angle.
Thus no phototropic response is found in the tendril of Passiflora even under the action of strong light.
I shall now describe the phototropic effect of unilateral light in pulvinated, and in growing organs.
But the same leaflets acted on by light from below exhibit a folding upwards, the phototropic effect being now negative.
We shall find in the next chapter that the intensity of phototropic effect is proportional to the quantity of incident light.
