Resin tapping is an activity designed to extract resin from trees, especially species of the genus Pinus. Current systems and collecting are well known, but further study needed make these more efficient profitable for producers. Therefore, this work aimed evaluate effect five during different collection periods on production growth trees a population Pinus elliottii var. planted in Itapetining...

Introduction Pinus taeda stands for productivity and quality of its timber [1]. Researches using biotechnology are of great importance and have been applied to the improvement of its timber and plantation [2]. The main method of Pinus propagation is by seeds, once the minicuttings depends on the season of the year or depends of juvenile material [3-5]. Thus, researches on micropropagation of Pi...

Diplodia scrobiculata, a latent pathogen of Pinus spp. and other conifers with a limited distribution in the United States, Mexico and southern Europe, has not been reported previously in the southern hemisphere. This is unlike its close relative Diplodia pinea that is found in most parts of the world where pines are native or have been introduced. During an intensive D. pinea survey conducted ...

Pine wilt disease (PWD) constitutes a serious threat to pine forests. Since development depends on temperature and drought, there is a concern that future climate change could lead to the spread of PWD infections. We evaluated the risk of PWD in 21 susceptible Pinus species on a global scale. The MB index, which represents the sum of the difference between the mean monthly temperature and 15 wh...

Bakernema dauniense n. sp., a bisexual species from the rhizosphere of Pinus halepensis Mill. in Italy, is described and illustrated. Primary differentiating characteristics of the female are body annules bearing short, membranous projections 1.4-2.2 mum long, an anterior vulval lip slightly overlapping the posterior, and a linearly arcuate vagina.

background: diabetes mellitus type 2 with dyslipidemia is a common disease. previous studies suggest that chemical constituent present in pinus eldarica (p. eldarica) nut posesess antioxidant properties and positively affect glucose metabolism. however blood glucose and cholesterol lowering effects of p. eldarica nut have not been studied so far. objective: the present study was undertaken to e...

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...

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...
