The Effect of Acid Rain on the Defense Response of Pines to Pinewood Nematodes
نویسندگان
چکیده
We examined the invasion rate of virulent and avirulent isolates of the pinewood nematode to Japanese black pine seedlings pretreated with simulated acid rain (SAR) at pH 3 and 2. Pretreatment with SAR at pH 3 reduced the invasion rate of virulent nematodes compared to control seedlings in both juvenile seedlings and 1-year-shoot segments of 3-year-old seedlings. This suggests that acid rain at pH 3 activates some defense response(s) of pines to the nematodes.

Pinewood Nematode, Bursaphelenchus xylophilus, Associated with Red Pine, Pinus resinosa, in Western Maryland.
Red pines Pinus resinosa in Garrett and Allegany counties, Maryland, were examined during 1982-84 to determine distribution of the pinewood nematode, Bursaphelenchus xylophilus, within and among trees. Approximately 25-year-old (younger) and 47-year-old (older) trees were subdivided into the following categories: 1) trees with mostly green needles; 2) trees with mostly reddish-brown needles; 3)...
متن کاملRelative susceptibility of four pine species to infection by pinewood nematode.
Mature trees of eastern white, jack, Scotch, and shortleaf pines were inoculated with 25,000-34,000 pinewood nematodes, Bursaphelenchus xylophilus, isolated from infected Scotch pines in Missouri. Equal numbers of trees of each species inoculated with distilled water served as controls. Nine of fifteen Scotch pines died within 4 months of nematode infection or during the winter and early spring...
متن کاملTransmission of Pinewood Nematode Through Feeding Wounds of Monochamus carolinensis (Coleoptera: Cerambycidae).
Transmission of pinewood nematode, Bursaphelenchus xylophilus, to mature, field grown Scots pines through feeding wounds of Monochamus carolinensis was investigated by caging nematode-infested beetles on pine branches for 24 hours. Nematodes were transmitted to 31 of 64 branches. Frequency of successful transmission was independent of the sex of the beetle but dependent upon beetle age. Transmi...
متن کاملRole of Phytotoxins in Pine Wilt Disease
Characteristic rapid death of pines after infection by Bursaphelenchus xylophilus suggests the involvement of phytotoxins in the pine wilt disease syndrome. Crude extract from diseased pine is toxic to pine seedlings, whereas an extract from healthy pine is not. The response of seedlings to the crude toxin is more prominent in susceptible pine species than in resistant ones. Benzoic acid, catec...
متن کاملThe pinewood nematode: regulation and mitigation.
In North America, the native pinewood nematode (PWN), Bursaphelenchus xylophilus, kills exotic pines. When inadvertently introduced to Japan and other Asian countries, PWN became a destructive pest of pines. The PWN has been intercepted in pine shipments from North America to Europe, where there is concern that it may also kill pines and other conifers. To protect their forests from the PWN and...
