“…japonica on the agar appeared more suitable as inoculum than fungal material detached from cultures, though there are examples of fungal inocula prepared on wood placed on the surface of colonized media, for example wooden tooth picks colonized with Amylostereum laevigatum used to inoculate Cryptomeria japonica (Tabata 2003), and from the use of Perenniporia subacida to inoculate Ch. obtusa (Tabata et al 2002). Isolate C20 was not suitable as PA inoculum in inoculation test 1.…”

The ascomycete Cistella japonica was cultured on potato dextrose agar medium (PDA) for inoculation into Chamaecyparis obtusa, enabling the development of an inoculation method suitable for use in a breeding programme aimed at selecting for families of Ch. obtusa resistant to resinous stem canker. Using PDA to generate the inoculum resolved the problems encountered with the previously used mixed medium of rice bran and wheat bran, including unfavourable characteristics, uncertain growth of Ci. japonica mycelia, and a complex culturing operation. The inoculation test induced resin exudation similar to that observed in natural infections, and reproduced clonal differences with regard to damage severity.

The clonal structure of Perenniporia subacida, a wood-rotting basidiomycete, was studied in a 30-year-old stand (site A; 1 ha) and a 43-year-old stand (site B; 0.5 ha) of Chamaecyparis obtusa in northern Kagawa Prefecture, Japan. A total of 110 isolates from decayed trees, stumps, wooden fences, logs, and mycelial mats were analyzed by amplified fragment length polymorphism (AFLP) and somatic incompatibility test (SIT). The results of AFLP, which agreed with those of SIT, revealed that the P. subacida population consisted of at least 17 genets at site A and 6 genets at site B. Individual genets were found in 1 to 9 trees at site A and in 1 to 7 trees at site B. One particular genet had spread over a distance of 70 m. Root contacts were observed among roots of decaying stumps and living trees at both sites. White mycelial mats were often found where roots made contact between stumps and neighboring trees. These results suggest that P. subacida spreads vegetatively over significant distances through root contacts.
