Twelve tubes in each of three replications/treatment were fumigated in continuously-stirred tank reactors in a greenhouse for 6 h/day on 4 consecutive days/week. Soil was watered 3 days/week with deionized water amended with ions and adjusted to pH 4.3 with H2SO4 + HNO3 (70 meq SO4(2-): 30 meq NO3(-)). After 10 weeks the amount of soil surface covered by moss (predominantly Ditrichum pusillum, but also D. lineare, and Pohlia nutans) was estimated visually and assigned a rating on a scale of: 1 = 0-25%; 2 = 26-50%; 3 = 51-75%; 4 = 76-100%. Linear regression analysis revealed a significant (p < 0.001) negative relationship between coverage ratings and O3 concentration. Surface coverage in tubes exposed to 0.32 or 0.24 ppm was about half of that for 0.00 ppm (mean ratings of 1.1, 1.4 and 2.6, respectively). Coverage differences appeared to be due in part to O3 suppression of plant numbers.

Soil water potential was maintained near pot capacity (−0.03 MPa) or soil was allowed to dry to approximately −1.0 MPa and resaturated. Chlorotic mottling and flecking of needles due to O3 injury were observed for seedlings from all pine families. Soil water deficit lessened the intensity of O3 symptoms, possibly due to stomatal closure. Exposure to O3 and soil water deficit each resulted in less seedling volume growth and dry weight, and changed the nonstructural carbohydrate content of seedlings compared with controls. Increasing O3 concentrations resulted in a linear reduction in foliar starch content but did and affect hexose or sucrose content. Soil water deficit resulted in less starch and soluble sugar contents in above- and below-ground plant parts compared with controls. Soil water deficit did not affect numbers or percentages of roots that formed ectomycorrhizal tips. A linear dose-response relationship between O3 and ectomycorrhizae was observed. The number of ectomycorrhizal tips/cm long root and the percentage of feeder roots that formed ectomycorrhizae were lower as O3 concentration increased. Overall, each stress alone caused less seedling growth and carbohydrate content compared with controls, but only O3 was responsible for suppression of ectomycorrhizae.}, number={1}, journal={ENVIRONMENTAL POLLUTION}, author={MEIER, S and GRAND, LF and SCHOENEBERGER, MM and REINERT, RA and BRUCK, RI}, year={1990}, pages={11–27} }

Ectomycorrhizae were quantified as the total number of ectomycorrhizal tips per centimeter, and as the number of ectomycorrhizal tips for each morphotype and for Cenococcum geophilum. Rain solutions were applied to the soil alone, to foliage and stem alone, or to entire potted seedlings. Final soil pH was linearly related to rain solution acidity. Lower base saturation, calcium and zinc content, and higher exchangeable acidity were observed after pH 2·5 treatments if the soil was exposed. Rain solutions and the subsequent changes in soil characteristics did not affect the total numbers of ectomycorrhizal tips. Four morphotypes of ectomycorrhizae observed for these seedlings were unaffected by simulated rain. However, the numbers of ectomycorrhizal tips formed by C. geophilum tended to increase with rain solution acidity after 50 applications. Method of rain deposition did not affect ectomycorrhizae, suggesting both plant and soil mediated responses may favor certain mycobionts. The results of this study indicate that short-term acidic deposition does not induce significant changes in the frequency of ectomycorrhizae, but higher numbers of C. geophilum tips suggest there may be changes in the relative occurrence of specific morphotypes of fungus species.}, number={4}, journal={ENVIRONMENTAL POLLUTION}, author={MEIER, S and ROBARGE, WP and BRUCK, RI and GRAND, LF}, year={1989}, pages={315–324} }

Miller. Canker incidence ranged from 0 to 70%. Horizonal soil samples were analyzed for their chemical and physical properties, and aspen leaf lamina tissue was analyzed for nutrient concentrations. A model accounting for 92% of the variation in canker incidence was constructed, utilizing 56 measured parameters, through the use of simple- and multi-correlation statistical analyses. Highly significant negative correlations were observed between canker frequency and each of aspen cover density, soil moisture, abundance of soil mottles, soil consistence, exchangeable soil Mn, Ca, and Na, and aspen tissue concentrations of Mn, Ca, and Na. Positive correlations were observed between canker incidence and each of soil temperature, soil depth, bulk density, rooting depth, and soil fractions over 2 and 10 mm. The association between exchangeable soil nutrients and aspen tissue concentrations was highly significant (p = 0.01). It is concluded that physical and chemical parameters of the soil which related most directly to moisture comprise a system of variables which are highly related to Hypoxylon canker incidence in trembling aspen. }, number={1}, journal={CANADIAN JOURNAL OF FOREST RESEARCH}, author={BRUCK, RI and MANION, PD}, year={1980}, pages={17–24} }
