Japanese larch

Samples of wood of various species were steam-treated at 150 °C, or oven-heated in air at 150°C, for various time periods and attack by the termite species C. formosanus or R. speratus determined (Doi etal., 1997, 1999). Steam heat treatment had the effect of encouraging attack upon the treated wood specimens, whereas dry heat treatment had little effect except for heat-treated Japanese larch with R. speratus.

Several flavonoids were isolated from either the wood of the Japanese larch Larix leptolepis (Pinaceae) or from the wood of Prunus species.152 In total, 14 flavonoids were tested for antifeedant activity against C. formosanus. Although all flavonoids did exhibit antifeeding behavior, there were large variations. Three compounds,... 

Cause Larch branch canker. This fungus produces sunken areas on the bark that are surrounded with drops of resin. Cut out and destroy affected parts as soon as detected once established, there is no control. European larch Larix decidua) is prone to serious infections Japanese larch L. kaempferi) is less susceptible to the disease.

Provenance testing for this species has not been extensive, probably because of the North American interest in provenances of much faster growing exotic larches such as L. kaempferi (Japanese larch), which can grow up to three times as much volume on some sites in eastern Canada (Fowler et al, 1988). Tamarack has been infrequently included in the provenance trials of exotic larches, and then only as a control (Boyle et al, 1989). Thus, comprehensive provenance trials of tamarack are young relative to those of many other species.
