Applications of biotechnology to tropical fruit crops in Australia and worldwide

摘要: Tropical fruits play an important role in the world economy. They make a substantial contribution to human nutrition and are used for medicine, timber, fuel livestock feed. The major tropical fruit crops banana, mango, pineapple, papaya citrus; however, it is estimated that more than 400 species harvested Asia, Pacific Oceania region. Other regions such as Central South America rich biodiversity. During last 20 years, biotechnology has been applied many species. In Australia, micropropagation systems have developed papaya, ginger, passionfruit coffee; good embryogenic protocols employed mango papaya. Cryopreservation being of Transformation produce disease resistant cultivars banana papaya; and, prevent blackheart, control flowering delay ripening pineapple. single significant commercial application transformation Papaya Ringspot Hawaii.
