Avocado trees reach up to 60 feet in height and thrive in USDA zones 9-11. All parts of the tree, including fruit, are toxic to animals. Trees need at least 8 hours of sunlight daily. Best planted outdoors in spring, 10 feet from structures
Agronomy combines biology, chemistry, economics, ecology, and genetics for plant production. Agronomists study plants for food, fuel, fiber, chemicals, recreation, and conservation. Plant breeding increases yields and improves nutritional value of crops
Parthenocarpy is the production of seedless fruit without fertilization. First scientifically described by Fritz Noll in 1902. Occurs naturally as a mutation affecting all flowers
Asexual reproduction produces genetically identical offspring without gametes. Occurs through budding, fragmentation, spore formation, regeneration and vegetative propagation. Vegetative reproduction involves structural modifications of stem, roots or leaves. Clonal colonies form through vegetative reproduction, with single ramet being identical. Pathogens can be transmitted from parent to offspring in vegetative reproduction
