Rhizopogon is a hypogeous fungal genus that grows in an ectomycorrhizal symbiosis mostly with members of the Pinaceae family and its worldwide distribution correlates with natural and exotic Pinaceae forests. In Iran, Rhizopogon species have received scant attention from collectors in the past and have not been adequately collected. Few older studies, report the presence of R. luteolus (Saber 1...

the major objectives of this study were to find out the mechanism behind the sapstaining fungal hyphae penetration into wood elements using electron microscope and to evaluate the exact role of phenolic compounds existing in wood vinegar towards the sapstaining fungal growth inhibition. to formulate the new environmental friendly wood preservative, we neutralized (to ph 7) wood vinegar with nao...

effect of fire on phyto-sociology of understorey vegetation in chir pine forests of three different silvological characteristics was compared with pure grassland. 15 grasses, 1 sedge, 5 legumes and 21 non-legumes were recorded in the four study sites. floristic composition gradually increased from june to august and then declined slowly by october in all the plots. maximum number of species was...

abstract this study was performed in order to determine a suitable alternative substrate for peat in soilless culture in 2007. different plant wastes including carbonized rice hull, saw dust and dry pine leaves (pinus eldarica) were examined. treatments were 100% peat as control, peat plus dry pine leaves (1:1 v/v), peat plus carbonized rice hull (1:1 v/v) and peat plus saw dust (1:1 v/v). the ...

Pinus roxburghii Sarg. (syn. Pinus longifolia Roxb.) (Pinaceae), found in the Himalayan region, furnishes an oleoresin which is used as insecticides, disinfectants and liver disorders. P. roxburghii are reported to have wound healing, cytotoxic, antibacterial, antifungal and spasmolytic actions. The plant also shows beneficial effects in the treatment of cough, ulceration and genito-urinary dis...

Proanthocyanidins are among the most abundant constituents in pine bark extracts (PBEs). This review summarizes medical research on PBEs from Pinus pinaster, Pinus radiata, Pinus massoniana, and other less well characterized species. The precise mechanisms of the important physiologic functions of PBE components remain to be elucidated, but there is evidently great potential for the identificat...

In this study, the Scots pine (Pinus sylvestris L.) C needles (i.e. the current-year-needles) were used as bioindicators in determining the aerial distribution pattern of sulphur emissions around industrial point sources at Kemi, Northern Finland. The average sulphur concentration in the C needles was 897 mg/kg (d.w.), with a standard deviation of 118 mg/kg (d.w.) and range 740 – 1350 mg/kg (d....
