Water status in living woody plants, Prunus yedoensis Matsuma and Zelkova serrata Makino was observed using an NMR microscope. Propriety of tracers, such as Mn and Cu , was wood species dependent, and successful observations of the water flow in vessels of the trees were determined by the appropriate paramagnetic ion species. These tracers were absolutely necessary to perform the three dimensional and real time reconstruction of the flow in vessels of the trees. Accumulation of the large amount of water in the cambium represented active metabolic activity in it. Swift water flow was observed in the outermost vessels and water transport rate in the inner vessel was more than 10 times slower than that in the outermost ones.

Coumarin, together with o-hydroxycinnamic acid and other compounds, has been reported in wood and barks of infected stems of Prunus yedoensis (60). The simple coumarins (Table 7.1.3.A) vary in their substitution of the aromatic ring. Prenylation (i.e., dimethylallyl substitution) also contributes to the great diversity. Umbelliferone (26), aesculetin (27), and scopoletin (28) corresponding in structure to j9-coumaric, caffeic, and ferulic acid - and various types of derivatives, are the three most common hydroxycoumarins in plants, including many species...
