Kiwifruit banana. Once a kiwifruit is ripe, however, it is preserved optimally when stored far from other fruits, as it is very sensitive to the ethylene gas they may emit, thereby tending to over-ripen even in the refrigerator. If stored appropriately, ripe kiwifruit normally keep for about one to two weeks. "Pseudomonas syringae actinidiae" (PSA) was first identified in Japan in the 1980s. This bacterial strain has been controlled and managed successfully in orchards in Asia. In 1992, it was found in northern Italy. In 2007/2008, economic losses were observed, as a more virulent strain became more dominant (PSA V). In
Actinidiaceae to four genera could be placed within the Actinidiaceae. Micromorphological characters have confirmed that "Sladenia" does not belong in the Actinidiaceae. Furthermore, biological characteristics of the cells, and molecular evidence have confirmed the three genera currently circumscribed in the Actinidiaceae, "Clematoclethra", "Saurauia", and "Actinidia", do indeed form a monophyletic group. Actinidiaceae The Actinidiaceae are a small family of flowering plants commonly known as the Chinese gooseberry family. The family has three genera and about 360 species and is a member of the order Ericales. They are temperate and subtropical woody vines, shrubs, and trees, native to Asia ("Actinidia" or kiwifruit,
