The growth of the extramatrical mycelium of ectomycorrhizal fungi and the growth response of Pinus sylvestris L.
SUMMARY Nine ectomycorrhizal fungi have been studied for their effect on the growth of Pinus sylvestris L. seedlings. The plants were kept growing for six months in root chambers with a changeable… Expand
Germination ecology of eleven species of Geraniaceae and Malvaceae, with special reference to the effects of drying seeds.
Germination and survival of water-impermeable seeds of 11 species of Geraniaceae and Malvaceae were monitored during dry storage and during burial in soil for up to 2.5 years. During dry storage,… Expand
Short-term phosphorus uptake rates in mycorrhizal and non-mycorrhizal roots of intact Pinus sylvestris seedlings.
SUMMARY Short-term phosphate uptake rates were measured on intact ectomycorrhizal and non-mycorrhizal Pinits sylvestris seedlings using a new, non-destructive method. Uptake was quantified in… Expand
Seasonal cycles in the germination capacity of buried seeds of some Leguminosae (Fabaceae)
Summary • The influence of seasonal factors on the germination of impermeable seeds of Fabaceae was studied. Seeds of 14 herbaceous species were buried for up to 2.5 yr and exposed to natural… Expand
Multiple environmental signals required for embryo growth and germination of seeds of Selinum carvifolia (L.) L. and Angelica sylvestris L. ( Apiaceae )
Germination and dormancy breaking requirements were studied in Selinum carvifolia (L.) L. and Angelica sylvestris L. ( Apiaceae ). Seeds of these two species have an underdeveloped embryo and are… Expand
Combinational dormancy in winter annual Fabaceae.
Among 14 species of herbaceous Fabaceae , all six winter annuals show a marked non-deep physiological dormancy of the embryo in addition to physical dormancy. This physiological dormancy is apparent… Expand
Zinc toxicity in ectomycorrhizal Pinus sylvestris
Six strains of ectomycorrhizal fungi were compared for their ability to increase zinc tolerance in Pinus sylvestris L. seedlings. Pioneer and ‘late-stage’ fungi as well as one strain collected from a… Expand
The use of inositol hexaphosphate as a phosphorus source by mycorrhizal and non‐mycorrhizal Scots Pine (Pinus sylvestris)
1. The external mycelia of the ectomycorrhizal fungi Thelephora terrestris and Suillus luteus, associated with Pinus sylvestris roots, exhibited a substantial extracellular acid phosphatase activity.… Expand
Morphological and physiological dormancy in seeds of Aegopodium podagraria (Apiaceae) broken successively during cold stratification
A low-temperature requirement for dormancy break has been observed frequently in temperate-climate Apiaceae species, resulting in spring emergence of seedlings. A series of experiments was performed… Expand
Seasonal dormancy cycles in the biennial Torilis japonica ( Apiaceae ), a species with morphophysiological dormancy
Torilis japonica (Apiaceae) has a widespread distribution, extending from western Europe to eastern Asia. In Europe, it usually behaves as a springgerminating biennial species. Ripe seeds of T.… Expand
