Sulfuric acid scarification of wax currant seeds from New Mexico

Abstract:

The germination response of 6 New Mexico sources of wax
currant (Ribes cereum Dougl.[Grossulariaceae]) to combinations of 0 to 120 d cold stratification and 0 to 8 min of acid scarification varied widely among seedlots. For most seedlots, cold stratification was more effective than scarification in improving germination, and scarification improved germination only at low, ineffective levels of cold stratification. For
3 of 6 seedlots, maximal germination was achieved without
scarification. For the remaining 3 seedlots, optimal scarification duration varied. Variability in sensitivity to acid scarification is discussed in terms of environmentally induced effects on seed coat structure and physiology.
