Explore the fascinating history and complex origins of citrus fruits in this 47-minute lecture by Professor David J. Mabberley. Discover how common citrus fruits like oranges, grapefruit, lemons, and limes are actually complex hybrids that originated in the forests of south-east Asia and do not exist in the wild. Learn about their spread westward through Arab traders and their deep cultural significance in both Asian and Western societies, from religious festivals like the Moon Festival and Feast of the Tabernacles to their influence on the House of Orange, the term "limeys," state flags, and even the Mafia. Understand the modern threats facing citrus crops, particularly the devastating huanglongbing (Citrus Greening) disease that endangers the future of citrus production and breakfast orange juice worldwide. Gain insights into promising research on Australian citrus species that may offer hope for the industry's survival. Professor Mabberley, a distinguished botanist and author of "Citrus: a world history," draws from his extensive research and expertise in tropical tree taxonomy to reveal how these hybrid fruits became the world's most significant tropical fruit crops while examining both their rich cultural heritage and uncertain future.
