Abstract
The purpose of this study was to understand water stress development in pine seedlings inoculated with Bursaphelenchus xylophilus. Leaf water potentials of four years old Pinus densiflora seedlings inoculated with the nematode were measured with a plant moisture system at predawn and midday. The midday leaf water potentials on the 35th day after the inoculation were -1.04 MPa in the infected seedlings, while -0.94 MPa in the non-infected seedlings. The predawn water potentials on the 56th day were -0.71 MPa in the infected, while -0.26 MPa in the non-infected. At this time the leaves of the infected seedlings became yellow and resin did not exude on the cut basal stem. Density of the nematode was maximum on the 28th day, but dropped sharply on the 68th day. The phloem and pith tissues became brown and the resin exudation reduced in the infected seedlings. In conclusion, pinewood nematode inoculation developed water stress in pine seedlings in a month.
