The Almonds and Related Species
Identification, Characteristics and Uses
Chapter
Almond species, in addition to their historical importance as food crops, are becoming increasingly utilized in reforestation, ecological restoration, and urban landsca**. Their historical distribution exten...
Chapter
Commercial almond cultivars (Prunus dulcis) are self-sterile, expressing gametophytic self-incompatibility and requiring insect pollinators for cross-pollinations. Self-fruitfulness is a major objective of almond...
Chapter
Considerable published information on almond species utilization focuses on their potential as valuable sources for genetic improvement through the breeding of cultivars and rootstocks. A number of useful trai...
Chapter
Taxonomic classifications utilize morphological, biochemical, and molecular differences. Almond species show a particularly large variation in nut and kernel traits. These often quantitative traits are less af...
Chapter
Almonds have hard shells (endocarps), and in some species, mechanical and/or chemical scarification, such as immersion in sulfuric acid, is required to achieve more consistent levels of seed germination. Seed ...
Chapter
Almonds and their wild relatives are grouped within the genus Prunus. Over 30 almond species and over 20 interspecies hybrids have been reported worldwide. Several reported species may be the same and are thus sy...
Chapter
Originally classified as Amygdalus communis, cultivated almonds, as well as their close relatives, are currently classified in the genus Prunus within the order Rosales, the clade Rosids, the family Rosaceae, and...
Chapter
Related species provide adaptation to a wide range of soils and climates, making them historically important as regional rootstocks. Utilization as rootstocks ranges from top-working naturally occurring specie...

Chapter
Cultivated peach is of global importance as both fresh market and processing cultivars and as rootstocks. Limited genetic options for breeding resistance to biotic stress is a consequence of a limited initial ...
