The biology of micorrhiza
[Text] : монография / J.L. Harley. - London : Leonord Hill (Books) Limited, 1959. - 233 p. : рис., цв.ил. - (Plant Science Monographs / Ed. by N. Polunin). - eng. - Библиогр.: c. 205-222. - 30.80 р.
Аннотация: The roots of all plants are associated in the soil with fungi and very many form specialized mycorrhizal organs with them. The ways in which these micorrhizal organs function is a problem of importance not only to academic botanists, but also to those concerned with the cultivation of economic plants. This book consists of a careful and detailed analysis of the available experimental evidence made against the background of a critical survey of the known facts about all aspects of the subject, the coherent picture that emerges, that various kinds of mycorrhiza are functional absorbing organs, has enabled the author to highlight the more important problems which remain to be solved

Antagonistic effects of some soil fungi on Fomes annosus in laboratory experiments
[Текст] = Antagonistiska effekter mot Fomes annosus hos nagra marksvampar i laboratorieforsok : научное издание / A. Hyppel. - Stockholm : Skogshogskolan, 1968. - 18 с. : рис. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 64). - eng. - Библиогр. в конце ст. - 0.20 р.
Аннотация: A wide antagonistic spectrum was demonsrated both within and between the species. The inhibition established was of a fungistatic type. In order to widen the knowlwdge of the variation in sensivity of F. annosus, 85 isolated mainly from field trials in Norway spruce were selected and screened to three strongly active mucorrhiza-forming fungi. As a rule all root rot isolates were highly sensitive to all three antagonists. Only three exceptions were obtained. A strong correlation exists between the time advantage and the toxic level obtained

Effect of Fomes annosus on seedlings of Picea abies in the presernce of Boletus bovinus
[Text] = Fomes annosus' inverkan pa groddplantor av Picea abies i narvaro av Boletus bovinus : научное издание / A. Hyppel. - Stockholm : Skogshogskolan, 1968. - 16 p. : рис. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 66). - eng. - Библиогр. в конце ст. - 0.20 р.
Аннотация: The mycorrhiza-forming fungus Boletus bovinus (L. ex Fr.) O. Kuntze was shown to protect seedlings of Norway spruce from the usually fatal attacks, which result from treatment with the root rot fungus Fomes annosus (Fr.) Cke. New techniques were developed for the culture and application of both species of the microorganisms. The investigation was performed under greenhouse conditions

Utilisation of various nitrogen sources, in particular bound soil nitrogen, by mycorrhizal fungi
[Text] = Mykorrhizasvamparus utnyttjande av olika kvavekallor, sarskilt bundet markkvave : научное издание / G. Lundeberg. - Stockholm : Skogshogskolan, 1970. - 95 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 79). - eng. - Библиогр.: с. 84-87. - 1.00 р.
Аннотация: Mycorrhiza-forming species mainly of the genera Amanita, Boletus and others and some litter-decomposing species were employed. For ecological characterisation of the experimental material, most of these species were tested for the ability to produce the extra-cellular enzymes, cellulase, pectinase, proteinase and laccase. The result from experimental series having raw humus as the only nitrogen source indicated that the myccorhiza-forming fungi, like most of the litter-decomposers, could utilise to a very limited extent or not at all the nitrogen bound in the humus. The inoculation of cultures of pine seedlings on gamma-sterilised, N15- labelled raw humus with pure culture suspensions of different mycorrhiza-formers and litter-decomposers influenced to varying degrees both the supply of assimilable nitrogen and plant development.

Mycorrhiza and tree nutrition in poor forest soils
[Text] = Mykorrhiza och naringsupptagning hos skogstrad i mager skogsjord : научное издание / E. Bjorkman. - Stockholm : Skogshogskolan, 1970. - 24 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 83). - eng. - Библиогр.: с. 22-23. - 0.25 р.
Аннотация: In the present paper it is shown how Boletus subtomentosus, that normally is a mycorrhiza forming fungus can stimulate the development of pine plants. A physiological strain of this fungus is used which has the ability to decompose litter. The typical mycorrhiza fungus also stimulated the plant growth to a certain extent. However, the stimulating effect ceased when strong fertilization was used or when the light intensity was reduced. Constant illumination resulted in the plants developing well and with good mycorrhiza formation. When the period of illumination was reduced to 16 hours a day the plants developed less vigorously and the mycorrhiza formation was reduced.

Plant condition and plant growth: Planting experiments with spruce (Picea abies (L.) Karst.) on Calluna heath land
[Text] = Plantkondition och tillvaxt : Planteringsforsok med gran pa ljunghedar : научное издание / E. Bjorkman. - Stockholm : Skogshogskolan, 1970. - 36 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 88). - eng. - Библиогр.: с. 33-34. - 0.36 р.
Аннотация: A study has been made of the effects of different methods of fertilizing spruce plants (Picea abies (L.) Karst.) in the nursery before planting them on Calluna heath land in S.W. Sweden. It was found that the use of superphosphate led to strongly stimulated development of the plants after planting. The same was also the case after fertilizing with NPK, while the use of only a similar amount of nitrogen or potassium as is contained in NPK did not have a positive effect. The growth of spruce was often further promoted if a dose of lime (5,000 kg/ha) was added in the nursery. Fertilization after planting was effective only if carried out after the plants had overcome the stunt period of juvenile development.
