Title
Leuco-anthocyanins. 3. The nature and systematic distribution of tannins in dicotyledonous plants.
E. C. Bate-Smith; C. R. Metcalfe Journal of the Linnean Society of London Botany 1957. doi:10.1111/j.1095-8339.1957.tb00030.x
Other claims from this paper (8)
- Association Presence or absence of tannins in stems coincides with leuco-anthocyanins in leaves in 83% of cases.
- Mechanism The histological tannin reaction is most commonly due to leuco-anthocyanins.
- Association In about one-fifth of the disagreeing cases, ellagic acid is present in the leaves.
- Observation Leuco-anthocyanins are present in the stems of Cornus, Sambucus and Passiflora although absent from the leaves.
- Observation Some dicotyledonous families are highly tanniniferous while in others little or no tannin is detected.
- Observation The occurrence of tannins shows no more than a limited agreement with the composition of the orders.
- Association The occurrence of tannins runs parallel to the phylogenetic status of the families.
- Association The capacity to synthesize tannins seems to decrease as the advancement index increases.
