Phenolic composition of Pine (Pinus spp.) honey from Turkey

open access: yesJournal of Apitherapy and Nature, 2020
In this study, the phenolic components of pine honey, which is a secretion honey, were studied. Total polyphenol content and total flavanoid contents of the honeys were ranged from 30 to 52 mg GAE/100 g and 0,86 to 1,58 mg QE/100 g, respectively. The phenolic composition of the honeys were analyzed by HPLC-UV assay with C18 column.

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

open access: yesOikos, EarlyView.
By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.

Importância da micorrização em viveiros de Pinus spp.

open access: yesAgropecuária Catarinense, 2002
A micorrização é particularmente importante para o desenvolvimento de espécies dos gêneros Pinus e Eucalyptus, entre outros gênerosde plantas, que dependem dessas associações simbióticas para um bom crescimento. Para Pinus, a associação com fungos ectomicorrízicos é indispensável ao estabelecimento e desenvolvimento das plantas.
