plant identification with microscope?
I can sometimes identify plants with the aid of a field guide and sometimes not. Sometimes leaves and other stuff from the plant falls on the ground and is easily collected for its own sake, just to have a record of what I found. I own a microscope which can give magnification from 50X to 675X. I don't have a laboratory and am certainly not going to try doing DNA sequencing. I'm just wondering whether there are easy ways to distinguish, say, different trees by looking at parts of them (e.g. leaves) under a microscope. E.g. maybe their cells look different? -- Ignorantly, Allan Adler * Disclaimer: I am a guest and *not* a member of the MIT CSAIL. My actions and * comments do not reflect in any way on MIT.

There are certain traits which are correlated with ploidy level (e.g. size of stomata, size of pollen grains). These could be used to distinguish cytotypes. I suspect that in some groups examination of trichomes can distinguish non-flowering material of related species. (At the right time of year one can distinguish material of Tilia platyphyllos and Tilia x vulgaris from the texture of the leafs; the pubescence of the former is not always visible to the naked eye, but can be detected by touch.) -- Stewart Robert Hinsley |
