Inoculum Preparation

Mycelial slurries prepared from agar plates of ectomycorrhizal fungi were used to inoculate 7-week-old container-grown jack pine. Seven of 15 species formed mycorrhizae after 18 weeks and included Thelephoraterrestris Ehrhart ex Fr., Laccariaproximo Boudier, Hebeloma sp., Pisolithustinctoris (Pers.) Coker & Couch, Sphaerosporellabrunnea (Alb. & Schw. ex Fr.) Svrcek & Kubicka, Cenococcwngeophilum Fr., and an E strain (sensu Mikola) isolate. Species of Tricholoma, Suillus, Amphinema, and Hydnum failed to form mycorrhizae. The use of a mycelial slurry has the advantage of saving considerable time in inoculum preparation and should be useful for experimental purposes.

Colony Forming Units

Two species of ectomycorrhizal fungi, Paxillus involutus and Suillus tomentosus, and a bacterial strain of Bacillus subtilis, were tested against Fusarium moniliforme, the causal agent of damping-off in jack pine (Pinus banksiana) seedlings. Both P. involutus and B. subtilis inhibited in vitro growth of F moniliforme. The culture filtrates of P. involutus and B. subtilis were toxic to F moniliforme, but chlamydospore formation of F moniliforme was observed. Greater jack pine seedling survival was observed when co-inoculated with P. involutus and B. subtilis than with F moniliforme alone. S. tomentosus neither inhibited in vitro growth of F moniliforme nor increased survival of jack pine seedlings against F moniliforme. F moniliforme reduced ectomycorrhiza formation on jack pine seedlings by P. involutus and S. tomentosus. The number of colony forming units of F moniliforme was significantly reduced when seedlings were inoculated with P. involutus and B. subtilis alone or in combination. S. tomentosus, on the other hand, did not reduce the number of colony forming units of F moniliforme. The suppression of F moniliforme growth by P. involutus and B. subtilis involved production of antifungal compounds.

Substrate Fertility

Containerized jack pine (Pinusbanksiana Lamb.) seedlings were grown in a peat moss – vermiculite substrate and inoculated at sowing with pure cultures of three ectomycorrhizal fungi. After 18 weeks of growth in the greenhouse, seedlings inoculated with Laccariabicolor had 97% of their short roots mycorrhizal, while those inoculated with Hebelomacylindrosporum had 36% of their rootlets mycorrhizal. No mycorrhizae were obtained with Rhizopogon sp. After both 12 and 18 weeks of growth with the fertilization schedule used, seedlings colonized with L. bicolor and H. cylindrosporum were significantly smaller than those inoculated with Rhizopogon sp. or control seedlings. After 18 weeks of growth, the available nitrogen (N) content of the substrate was considerably greater with L. bicolor inoculated seedlings than with control seedlings, whereas the available phosphorus (P) content of the substrate was the same for these two treatments. Also, after 18 weeks, seedlings mycorrhizal with L. bicolour had a. greater concentration (%) of N and P in their tissues than control seedlings; however, they contained fewer milligrams of N and P than control seedlings. From our results on substrate fertility of mycorrhizal seedlings, we state that it is possible to induce mycorrhiza formation of jack pine seedlings with L. bicolor when substrate fertility in available N and P is less than or equal to 39 and 60 ppm, respectively, and that it is possible to maintain L. bicolor mycorrhizae when N and P fertility is less than or equal to 24 and 28 ppm, respectively. From analysis of tissue nutrient content in mycorrhizal seedlings, it appears that the appropriate N and P concentrations to maintain mycorrhiza formation of jack pine seedlings with L. bicolor are less than or equal to 1.6 and 0.2%, respectively.

Flooding is an environmental stress for plants that not only limits aeration and nutrient acquisition, but also disturbs underground plant-associated fungal communities. Despite frequent flooding, red pine (Pinus densiflora) seedlings thrive in streamside environments. However, whether the compatible ectomycorrhizal fungi (EMF) of red pine are affected by natural flooding is unclear. As EMF are vital symbionts for the development of many trees and allow them to overcome various environmental stresses, in this study, the EMF species associated with red pine seedlings in a streamside environment in Korea were investigated after flooding. The EMF species in 47 seedlings collected from the streamside site were identified by observing their different morphotypes using internal transcribed spacer sequence analysis, and a total of 10 EMF species were identified. The EMF species diversity was lower than that in samples collected from a nearby forest analyzed as a control. The dominant EMF species of streamside seedlings included Amphinema spp., Rhizopogon luteolus, Suillus luteus, and Thelephora terrestris. This study could serve as a basis for investigating the mechanisms by which advantageous EMF aid plant development under flooding stress.

Accelerated Growth

Jack pine (Pinusbanksiana Lamb.) seeds were sown in October, January, and March, and the seedlings were cultured under accelerated growth conditions in a greenhouse. At biweekly intervals, from May 15 to August 15, they were transplanted to a nearby nursery and sprayed with GA4/7 or GA4/7 + NAA. The following spring a fourfold increase in flowering was noted in trees receiving either of the GA4/7 treatments. Trees in the March sowing did not flower. The data suggest that the increased flowering was caused by GA4/7-mediated differentiation of lateral long-branch primordia into ovulate strobili.

Survival And Growth

Abstract This paper is the first general review of the affects of container volume on the survival and growth of containerized white spruce, black spruce, and jack pine seedlings. The review shows that the literature on this topic is fragmentary and inconsistent. Seedling growth in the greenhouse production phase has been more completely quantified than subsequent establishment and growth after out-planting in the field. In the greenhouse production phase, seedling growth increased from 72 to 360% when the container volume was tripled in size. After outplanting in the field, seedling growth trends were more variable. Seedling height growth increased from 34 to 84% when container volume was tripled in size. Seedling survival was more difficult to assess because of limited data. Only white spruce showed a 10% increase in survival with an increase in container volume. The indications from this literature review suggest that nursery managers and practicing foresters should become more aware of the limitations imposed on seedling survival and growth due to container volume. To maintain optional survival and growth for white spruce, black spruce and jack pine, the container volume should range from 90 to 120 cm3. North. J. Appl. For. 5:185-189, Sept. 1988.
