Maturing Pine Tracheids
The cytoplasm of the interior of maturing pine tracheids is revealed by scanning electron microscopy as a lamellate and filamentous intravacuolar reticulum immersed in vacuolar sap. Formation of cytoplasmic spherules and the breakdown of the cytoplasmic reticulum initiate protoplast disintegration that terminates in tracheid maturation. The process is believed to involve vacuolar membrane trans...
متن کاملStatistical Downscaling HadCM3 Model for Detection and Perdiction of Seasonal Climatic Variations (Case Study: Khabr Rangeland, Kerman, Iran)
Rangelands are one of the most vulnerable parts concerning the climatechanges‟ impacts. These impacts are even stronger in the arid and semi-arid areas whererangeland ecosystems are in critical conditions. Therefore, it is crucial to figure out theactual dynamics of climate variations on the rangelands. The aim of this research was todetermine climate changes in Khabr rangeland, Kerman, Iran. S...
متن کاملFluorescence microscopy for measuring fibril angles in pine tracheids.
—Observation and measurement of fibril angles in increment cores or similar small samples from living pine trees was facilitated by the use of fluorescence microscopy. Although some autofluorescence was present, brighter images could be obtained by staining the specimens with a 0.1% aqueous solution of a fluoro chrome (Calcozine flavine TG extra concentrated, Calcozine red 6G extra, rhodamine ...
متن کاملFoliar moisture content variations in lodgepole pine over the diurnal cycle during the red stage of mountain pine beetle attack
Widespread outbreaks of the mountain pine beetle (Dendroctonus ponderosae Hopkins) in the lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of North America have produced stands with significant levels of recent tree mortality. The needle foliage from recently attacked trees typically turns red within one to two years of attack indicating successful colonization by ...
