Flowering and Fruit Characteristics of Black Walnuts: A Tool for Identifying and Selecting Cultivars (2008)

Abstract

Black walnuts (Juglans nigra L.) are valued for their uniquely fruity flavor and are often used as an ingredient in baked goods and ice cream or are eaten as a snack food. Although black walnuts can be harvested from wild trees, several cultivars have been selected for such characteristics as ease of cracking, size of kernel and thickness of husks and shells. Other characteristics, such as date of budbreak, time of flowering, length of season and date of harvest, are also important as there is considerable variation within the species.
