In this paper we present the application of a new methodology (Laser Biospeckle) to the study of barley (Hordeum vulgare L.) seeds. A brief description of the speckle phenomena and the used algorithm are discussed. We find that it is possible to characterize the biological activity of the seed. The activity of the embryo can be distinguished from that of the endosperm. Experimental results are shown. Biospeckle could be a potential methodology to assess viability, dormancy detection and water sensitivity in barley seeds
