The light‐induced unrolling of primary leaves of dark‐grown wheat ( Triticum aestivum L. cv. Weibull's Folke) and barley ( Hordeum vulgare L. cv. Weibull's Ida) does not follow the reciprocity law but shows maxima and minima like the phototropic dose‐response curve. These fluctuations of the unrolling can be explained by differences and non‐synchronizations of the growth in width of the two sides of the leaves. As the thickness of the leaves is small, even minute differences between the widths of the two sides will give rise to great changes in the unrolling and thus in the projection values.
