Physico-Chemical Properties of Plant Saps in Relation to Phytogeography

The Physico-Chemical Properties of Plant Saps in Relation to Phytogeography was first published in 1934. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.This book includes data on native vegitation gathered by the noted botanist J. Arthur Harris in the eastern and western United States, the Hawaiian islands, and Jamaica over a period of 18 years. Included more than 12,000 series of determinations of freezing-point depression, specific electrical conductivity, chloride and sulphate content in grams per liter of sap, and occasional determinations of hydrogen ion concentration. A separate index to the data is included for use by those wishing to make ecological studies of plants in particular communities.
