| Abstract: | Measurement of nuclear magnetic resonance (NMR) relaxation times (transverse [T2] and longitudinal [T1]) for Hedera helix L. cv. Thorndale (ivy) bark water indicates the presence of at least two populations of water with different relaxation characteristics. One population of water with short T2 and T1 was found to be composed of both hydration water and extracellular free water. The second population of water with long T2 and T1 was identified as intracellular bulk water. |
