Abstract
Marked differences in silicon content in internodes of two sugarcane cultivars as revealed by neutron activation analysis, were closely correlated with number of silica cells per unit area in the epidermal system of the internodes of the two cultivars, as indicated by scanning electron microscopy and X-ray analysis. Light microscopy of epidermal peels showed that silica cells are capable of transmitting significantly more light through themselves than do other types of adjacent epidermal cells. This could be of great significance to total amount of carbon fixed by photosynthesizing mesophyll cells in leaves and cortical cells in internodes below the epidermis, especially in sugarcane cultivars with high densities of silica cells in their shoot epidermal systems. This has led to propose a window hypothesis, which indicates that silica cells in sugarcane, and in other grasses, act like windows in the epidermal system, allowing more light to be transmitted to photosynthetic tissue below than would occur if silica cells were absent.
