The white pine cone beetle, Conophthorus coniperda, exhibited dose and enantiospecific responses to alpha-pinene in stands of mature eastern white pine, Pinus strobus, in a seed orchard near Murphy, N...
I report on the attraction of the white pine cone beetle, Conophthoru.s coniperda (Schwarz) (Coleoptera: Scolytidae), to traps baited with the host monoterpene limonene in western North Carolina. Both...
The enzyme preparation, about 100 fold purified, shows optimal activity at pH 4.8 and 5.9. This activity lessens rapidly at 40-60 degrees C, and retains 20% at 100 degrees C. These results of heat sta...
Oils were extracted from fully ripen Pinus pinea L. and Pinus halepensis Mill seeds and fatty acid composition has been established by capillary gas chromatography. Seeds are rich in lipids, 34.63-48....
Pretreatment of mice with ammonia extract of seed shell of Pinus Koraicenis, via the intraperitoneal or intravenous route, effectively protected them from lethal infection of Escherichia coli, Klebsie...
Acid treatments significantly change the physical and chemical properties of red-yellow soil by lowering its pH value and leaching out aluminum(Al) ions that are harmful to the growth of plants. The s...
Changes in nucleic acid fractions of Pinus resinosa during seed germination were studied. At various stages of seed germination, embryos and megagametophytes were surgically separated and nucleic acid...
