To visualize the penetration of applied substances into the leaf, a fluorescent analog of glucose solution (NBDG: 2-NBDG = 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxyglucose. λ Ex/Em (nm) 465/540) was applied to the leaf surface. The NBDG solution was prepared and used at a concentration of 30 mM.
