Photosynthesis in the Ear of Barley

Nature volume 184, pages 20312032 (26 December 1959) | Download Citation



THE ear of cereals such as barley and wheat is an important photosynthetic organ in providing carbohydrate substrate for grain filling. This has been established by several workers, most recently by Archbold1 for barley and Asana and Mani2 for wheat. Their technique, as of previous workers, involved opaque shading of the ear to prevent photosynthesis, the resulting reduction in grain weight being taken to represent the normal ear contribution. Reductions of the order of 30 per cent have been obtained (Archbold measured whole ear weight only).
