Glossiness of Leaf Blades in Sorghum (<i>Sorghum bicolor</i> L. Moench); Its Visual and Ultrastructural Studies
The glossy leaf is an important character related with disease and pest resistance as well as varietal differences in Brassica oleracea and Zea mays. The author aimed to clarify the characteristic of glossiness that was newly found in sorghum cultivars. The visual difference between glossy and non-glossy plants could be identified by whether or not sprayed water adheres to leaf blades. The phenotype of non-glossy plants whose leaves shed water was due to the high density of star-shaped waxes that were detected in the ultrastructural observations. Moreover, true-glossy plants which water adheres to the surfaces of all leaves from 1st to flag leaf stages were found among Indian indigenous cultivars. The visual character of true-glossy plants was due to a reduction in the number of star-shaped waxes on leaves from 1st to 5th leaf stages in the observation by scanning electron microscope (SEM).
