physiological aspects underlying the improved outplanting performance of pinus pinaster ait. seedlings associated with ectomycorrhizal inoculation. | mycorrhizal inoculation of conifer roots is a key strategy to optimize establishment and performance of forest tree species under both natural and cultivated conditions and also to mitigate transplantation shock. however, despite being a common practice, inoculation in outdoor nursery conditions has been poorly studied. here, we have evaluated effectiveness of four fungal species (lactarius deliciosus, lactarius quieticolor, pisolithus arhizus, and suillus luteus) in the production of mycorrhiza ... | 2013 | 23674120 |
bioactive microconstituents and antioxidant properties of wild edible mushrooms from the island of lesvos, greece. | crude composition, fatty acids, sterols, total phenolic content (tpc), individual polyphenols and terpenic acids were determined in five wild edible mushrooms species (lactarius deliciosus, lactarius sanguifluus, lactarius semisanguifluus, russula delica, suillus bellinii) from lesvos island, greece. in addition, the dpph scavenging capacity, the ferric ion reducing power (frap) and the ferrous ion chelating activity of mushroom methanolic extracts were assessed. among sterols, ergosterol predom ... | 2013 | 23354393 |
structure feature and antitumor activity of a novel polysaccharide isolated from lactarius deliciosus gray. | a novel heteropolysaccharide was isolated from the fruiting bodies of lactarius deliciosus gray through deae-cellulose column and sephadex g-100 column. the l. deliciosus gray polysaccharide (ldg-a) had a molecular weight of 1.1×10(4) da and was mainly composed of l-mannose and d-xylose (l-man and d-xyl) which ratio was 3:1. as a precondition to understand the bioactivity, structural feature of l. deliciosus gray polysaccharide (ldg-a) were investigated by a combination of total hydrolysis, meth ... | 2012 | 24750736 |
