摘要

For over thirty years, scientists with the University of California Pomology Department at Davis, in cooperation with their colleagues in Cooperative Extension, have researched the cause and solution for pistillate flower abortion (PFA) in walnut (Polito et al.). Included in this dedicated team are Dr. Vito Polito, Pomology Department Chair and Professor, Dr. Peter Catlin, Professor Emeritus who spent much of his career studying multiple cultural factors suggested as the cause for PFA, and Farm Advisors Steven Sibbett (Tulare County, retired and Emeritus), Joe Grant (San Joaquin County) and Kathy Kelley (Stanislaus County).
