| seasonal changes in needle water content and needle aba concentration of japanese red pine, pinus densiflora, in declining forests on mt. gokurakuji, hiroshima prefecture, japan. | to evaluate the effects of air pollution on the decline of pinus densiflora forests, various research has been conducted around mt. gokurakuji (34 degrees 23'n, 132 degrees 19'e, 693 m a.s.l.) north of the seto inland sea, west japan. to investigate the mechanisms responsible for decreases in photosynthesis (pn) and stomatal conductance (gl), delta13c of needles and seasonal changes in the water content (wc) and abscisic acid concentration (aba) of needles were measured in various stands. the de ... | 2006 | 16607566 |
