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
Kiwifruit of fruit, one male vine for every three to eight female vines is required. Other varieties can self pollinate, but they produce a greater and more reliable yield when pollinated by male kiwifruit vines. Kiwifruit is notoriously difficult to pollinate, because the flowers are not very attractive to the honeybees that farmers generically attempt to hire. This is, in part, because the flowers do not produce nectar. Honeybees are very inefficient pollinators in general, because they visit all species of flower indiscriminately, therefore the pollen needed for one plant is diluted. With Kiwi flowers it's worse, because the bees quickly
