According to the cell configuration observed under the microscope, the hypocotyl tissues looked healthy, so the trial to get the embryo may be succeeded. The callus derived from the cultured female gametophyte was cultured for over two years was observed. The cells of the callus were quite ...
A small amount of spores was selected in the ultra-clean workbench and a freehand section was made, which was observed under an optical microscope. After determining the spore morphology of the fungus, the spores were washed with sterile water and a single spore was selected and purified under...

The pilot study was based on tree rings covering 7 years (1999–2006, inclusive), representing four trees from one provenance grown on one planting site block. Tree rings were separated with a scalpel under a stereo microscope (Leica Wild M3B, Wetzlar, Germany). Whole-wood samples were homog...
Under the microscope, I extract the genitalia from the ring sclerite, and remove the parameres from the aedeagus in a separate little dish containing 100% ethanol. Once the pieces are all ready, I dip the sharp forceps into a vial of Euparal, and put the drop in the well of the card...
In using the electron microscope we have found that many cytoplasmic structures may be completely destroyed during embedding (not necessarily during fixation). In spite of this, tubules (Ger. Röhren) or strands (Ger. Stränge) have been visible in young coniferous sieve cells using electron ...
A simple, quick, and inexpensive technique to improve visualization of aspen (Populus tremuloides) tree rings under the microscope, the 'shadow technique', is described. The technique assumes appropriate preparation of increment cores or cross-sections and works well on the lighter portions of the ...
Three intact leaves per individual were selected from the FAA solution, and the leaf sections with a thickness of 6 μm were obtained by the paraffin section technique and stained [9]. The leaf sections were observed by a light microscope (Olympus Electronics, Inc., Tsukuba, Japan), and pho...
2a). The cells were segregated for these tissues, and under a microscope we could observe lignin only in xylem cells (based on the lignin stain safranine; Fig. 2b). We did not observe the perforation on the end walls, indicating that these cells are tracheids (Fig. 2b). The average ...
Development of flowers with petaloid stamens Following origination from the leaf meristems, the floral meristems of ancestral species of P. ostii differentiate into carpels, stamens, petals, sepals, bracts and leaves but not petaloid stamens (Supplementary Fig. 11a). However, parts of the ...
