I remember reading an old Carolina Biological Supply catalog when I was in high school which listed seeds for albino corn and albino tobacco. These plants are dead white because they have no chlorophyll. To raise one, I believe you had to slice off part of a leaf and attach an agar block rich in sugar (or some similar procedure, I am hazy on the details) I would like to know what kind of sugar or sugars are the best emulation of a leaf. Glucose? Fructose? Sucrose? Or would it make any difference?

Glucose? Fructose? Sucrose? Or would it make any difference? Sucrose is the best imitator of most leaves, but glucose may be taken up more readily by the seedling. Either would work. They would also provide a nice substrate for bacteria if the set-up is not sterile. Bob Vickery School of Biological Science University of New South Wales Kensington, NSW, Australia

Glucose? Fructose? Sucrose? Or would it make any difference? Plants may produce many kinds of sugars but they all love glucose :-) -- Mechael Kanovsky : BITNET kanov@bimacs.bitnet Biology dept. : UUCP uunet!mcvax!humus!bimacs!kanov Bar-Ilan University : ARPA kanov%bimacs.bitnet@cunyvm.cuny.edu Ramat-Gan Israel : CSNET kanov%bimacs.bitnet%cunyvm.cuny.edu@csnet-relay : NO-NET 4a hertzel st.
