Buxus sp. TS stained

#1 Post by mazo4033 » Sat Aug 21, 2021 10:16 pm

Buxus sp., a favorite of mine because its common name is "boxwood," and the transverse sections are rather box-shaped! :lol: But the wood from the shrub was commonly used to make boxes, among other pieces of woodworking, which is where the common name really comes from.

1 - introduction

Buxus sp. (sempervirens, I think)

Buxus sp. is either a shrub or a small tree. It is commonly grown as an ornamental plant and is ideal as a hedge or for topiary.

2 - procedure
A young shoot of the Buxus was hand-sectioned with a single-razor blade. Sections were mounted in a glycerin & PVA-glue-based mounting medium for a temporary mount. Three staining procedures were followed. Safranin-O and crystal-violet (separately) - the procedures are the same as detailed in my previous posts - then an experimental combination of methylene-blue and fuchsin.

3 - results

Safranin-O

Crystal-violet

Methylene-blue + fuchsin

4 - conclusion
I am happy with the results - I particularly like the staining of safranin-O, and I think that the methylene-blue + fuchsin combination produced a nice purple :)
