“…Mosse & Phillips (1971), for example, found that development of VA mycorrhizas in culture was dependent on adequate supplies of iron in the medium. Szaniszlo et al (1981) suggested that ectomycorrhizal fungi might provide plants with iron by liberating iron chelators, which were demonstrable in axenic culture and stable over a wide range of pH, and an increase of iron in seedling leaves of A. pseudoplatanus inoculated with Glomus has been reported to occur in a rendzina (Kabre et al, 1982). It can also be postulated that mycorrhizas increase plant tolerance of iron when it is present in excessive amounts.…”

“…B. pendula and A. pseudoplatanus have figured in several studies in which specific mycorrhizal fungi have been inoculated under axenic conditions and stimulation of plant growth has been recorded (Mason, 1975;Gaie, 1977;Le Tacon, Garbaye & Kabre, 1979;Kabre, Garbaye & Le Tacon, 1982). Controls in some cases included untreated soils, but few soil types were represented.…”

SUMMARYMycorrhizal infection of two-year-old seedlings oi Betula pendula Roth, and Acer pseudoplatanus L. was examined in a pot experiment, in relation to several soil variables (pH, organic matter, N, P, K, Ca, Fe, and phosphatase activity), host uptake of ^^P, and plant performance (height and weight), in 25 Cumbrian soils from natural and semi-natural habitats (such as woodland, carr and upland heath). Soils were used in a fresh state to maintain indigenous mycofloras and seedlings were raised from several seed-lots to include possible ecotypic variation. Infection (incidence and intensity) of both ' immature' and ' mature' mycorrhizas was estimated.Most plants were mycorrhizal, ectomycorrhizas occuring on Betula and vesicular-arbuscular (VA) endophytes in Acer. Differences in the degree of infection between soils, but not between seed-lots, were highly significant. Infection of one or both species was highly correlated with several soil factors (pH, organic matter, phosphorus and iron), and with all the plant variables. In Betula, evidence for most of these relationships was obtained only from 'immature' mycorrhizas, suggesting early physiological activity. Mycorrhizas accounted for a small but significant proportion of the variation in growth of both hosts, and soil properties accounted for a high proportion of the variation in both the plant growth and mycorrhizal infection, as shown by multiple regression analyses. Growth of Acer appeared to have a greater infiuence than soil factors on the variation in VA infection. 'Beading' of Acer roots was negatively correlated with plant weight and soil phosphorus, suggesting a morphological response to P-deficiency. Possible causal relationships between hosts, fungal symbionts and soils are discussed.

“…V. A. mycorrhizae enhance mineral uptake, especially that of phosphorus (ABBOTT and ROBSON 1977). Mycorrhizal plants often take up more phosphate from P deficient soils than non-mycorrhizal plants (KABRE et al 1982). SANDERS and TINKER 1971;MOSSE et al 1973;POWELL 1975;GIANINAZZI-PEARSON et al 1981 investigated the source of extra phosphate taken up by mycorrhizal and non-mycorrhizal plants in soils labelled with ''^P.…”

Responses of endomycorrhizal and non‐mycorrhizal plants of Acer pseudoplatanus to different levels of soluble and non‐soluble phosphorus

A greenhouse experiment compared growth and mineral nutrition of mycorrhizal and non‐mycorrhizal seedlings of Acer pseudoplatanus on a fumigated soil. The effects of mycorrhizal inoculation were examined at six rales of soluble phosphate and five rates of non‐soluble phosphate. Inoculation with Glomus mosseae markedly stimulated phosphorus uptake and growth only at the lowest level of soluble phosphorus. With 200 ppm of added monocalcium phosphate mycorrhizal infection depressed growth and considerably modified the relationships between yield and phosphorus concentration in plant tissues. The possible causes of growth depression at high level of added soluble phosphorus are discussed.
