Abstract

Summary Chase, M. W. & Hills, H. H.: Silica gel: An ideal material for field preservation of leaf samples for DNA studies. ‐ Taxon 40: 215–220. 1991. ‐ ISSN 0040‐0262. Silica gels an inexpensive and reliable substance to preserve field‐collected leaves for molecular studies of variation in DNA. A method for its utilization is explained, and results are presented, comparing total cellular DNA samples extracted from a set of fresh and silica‐gel dried samples of the same species, as well as examining the efficiency of endonuclease restriction and intactness of DNA from of a set of field‐collected leaves preserved with silica gel.
