Abstract:

In this paper, domestic and international research in recent 30 years on pecan including plant growth substance, genetic diversity and species identification, chemical constituents and utilization were reviewed. The author introduced the role of plant growth substance in exocarp cracking and its dynamic pattern, summarized the use of three genetic diversity analyses and species identification methods in pecan-the biological character identification, isozymes and molecular markers, summarized the research about antioxidants, protein, grease and other chemical components in pecan and their dynamic pattern, and the research frontier of pecan utilization. We thought learning of the advance research achievement was important. At the same time, research and development of suitable domestic cultivated variety and excellent plant of pecan was also crucial to pecan industry development.
