Abstract

Differences in the oxidation potential of tissue fluids of the sexes in dioecious plants have long been known and they appear to be causally related to the contrasts of the staminate and pistillate metabolism (2, 3, 5, 12, 13). Many plant scientists have considered the Manoilev oxidation reaction a valuable test in studies of this type (9, 10, 11). Although its simplicity and wide applicability decommend the Manoilev test, it has not been wholly satisfactory or reliable (8). Color reactions are often unsuitable as quantitative measures of oxidase activity due to the small amount of oxidation necessary to produce marked color change (7). This investigation describes the use of an iodimetric reaction in a study of press sap from staminate and pistillate plants in several dioecious species of flowering plants. Five different dioecious species were investigated comprising asparagus, hemp, Rumex, spinach and Smilax.
