Walnut Pollen Studies

investigations were initiated this year to develop field and laboratory viability assays for stored walnut pollen, indentify conditions suitable for in vitro pollen germination and pollen tube growth, and determine pollen tube growth rates in pistillate flowers. Results of this project will provide background information for future investigations of transmission of pollen-borne virus, factors i...
