increase in pollen aperture number, suggesting that pollen apertures are under strong selection pressure. This trend can be observed by comparing the aperture patterns in basal angiosperms (including monocots) with those of eudicots. Different developmental strate-gies operate for pollen apertures in basal angiosperms
Reuse your fountain pen by refilling the ink. Use the method that is suitable for your type of pen. 1  Fill ink in a piston converter pen by removing the cap and barrel and then dipping the nib inside the ink bottle. 2  Lower the piston to remove the air inside. 3  When you pull up the piston, the ink will be sucked in.
If the wood hasopen grain then I catch sanding dust on the sandpaper and use thedust to make slurry with CA. This slurry is used to coat the pen andfill the open grain. This layer of thin CA is sanded off, leaving thedust/CA slurry in the grain as filler.The dust is collected on thesandpaper underneath the pen.Thin CA is drizzled on and allowed tomix with the dust forming the slurry. Do this for the entire lengthof the pen. Use a scraper or sand paper to remove the CA layer backto the wood.I then sand 180-600 and 1500-12000 micromesh. I micromesh all wooden pens prior to applying the CA/BLO finish.o this for the entire lengthof the pen. Use a scraper or sand paper to remove the CA layer backto the wood.
