The germination and infection of conidia of brown spot needle blight fungus (Lecanosticta acicola) on pine needles were observed under scanning electron microscope (SEM). Results showed that the conidia on the needles of Pinus massoniana, P. elliottii and P. thunbergii all germinated in the same...
Many changes have taken place in the appearance and some physical properties of pine pollen in the process of wall breaking. The color changes to light yellow. Under the microscope, they found that the air sac structure was separated from the main structure of pine pollen, and the pine pollen...
All immunoreac- tions were observed using an Axio-phot microscope (Carl Zeiss, Germany) and these results were quantified using the Image J 1.46 software (NIH, Bethesda, MD, USA). AChE activity. Acetylcholinesterase (AChE) activity in hippocampus was determined using a AChE activity assay kit ...
annual resin duct number was quantified year-by-year with a binocular microscope separately in the earlywood, the latewood and total ring and expressed as the number of resin ducts per year (RD year−1). Annual resin duct density was calculated as the number divided by the corresponding...
Amy Orduño-Baez, Kyle Gunther, Mario Galvan, Stephanie Stragier, and Brian Myers for facilitating plant collections; Katya Geissler, Alice Hossfeld, and Sandra Hyssat for their help in leaf morphology; and The Binational Species Group and the Flores-Renteria laboratory for feedback on the manus...
(Figures1E, F, G). A continuous ring of mature and active cambium, and a complete ring of secondary xylem were developed in non-competent hypocotyls and epicotyls from 90-day-old seedlings, with interruptions at the primary leaf-axillary bud traces in epicotyls. However, while the cambium ...
Screw-pine strips were subjected to microstructural analysis using Field Emission Scanning Electron Microscope (FESEM) and Scanning Electron Microscope (SEM). The morphological structure of the un-treated screw-pine leaf was also analyzed as a control. The morphology was observed using SUPRA55VP with...
Sections were photographed with a digital camera attached to a microscope (×100 magnification) at a resolution of 1.8 μm per pixel. The radial diameter of the lumen and double cell wall thickness were measured and used to calculate radial TD on all individual cells along three to five files...
Broadleaf deciduous trees and shrubs are also present, and sometimes deciduous conifers such as Larch (Larix) species, but there is no doubt that evergreen conifers are particularly well adapted to harsh boreal conditions, including short growing seasons and cold, snowy winters. Thus, evergreen ...
The larvae that crawled out of galls with populations of 5, 6, 7, 8 or 9 larvae were frozen in the refrigerator for 2–3 min, and then the body length and body width of each larva were measured under an anatomical microscope. No fewer than three galls were treated in the different gr...
