Kiwifruit vines require vigorous pruning, similar to that of grapevines. Fruit is borne on 'one-year-old and older' canes, but production declines as each cane ages. Canes should be pruned off and replaced after their third year. In the northern hemisphere the fruit ripens in November, while in the southern it ripens in May. Four year-old plants can produce up to 14,000lb (6,400kg) per acre while eight year-old plants can produce 18,000lb (8,200kg) per acre. The plants produce their maximum at eight to ten years old. The seasonal yields are variable; a heavy crop on a vine one season generally comes with a light crop the following season. [1] Storage [ edit ] Clones of the new variety SunGold have been used to develop orchards in China, resulting in partially successful legal efforts in China by Zespri to protect their intellectual property. [25] In 2021, Zespri estimated that around 5,000 hectares of Sungold orchards were being cultivated in China, mainly in the Sichuan province. [26] Cultivation [ edit ] Tokoeka (Apteryx australis)- Also known as the Southern Brown Kiwi, the Tokoeka Kiwi is one of the largest types of this bird. They have a dark brown coloration with streaks on their feathers. Their legs are fairly short, and they have a long bill. People who smoke are at higher risk of plaque buildup, so eating kiwis may help prevent platelet accumulation and reduce the risk of atherosclerosis in this population ( 13). Many people enjoy eating kiwis raw. You can also incorporate them into a number of recipes, both sweet and savory.

Some people experience allergic reactions to kiwi. Anyone who develops hives, a rash, or swelling after eating kiwi should seek medical attention. Antioxidants — including vitamin C, choline, lutein, and zeaxanthin — help remove free radicals from the body. Free radicals are unstable molecules that the body produces during metabolism and other processes.

It can also improve overall bowel function if you suffer from conditions like irritable bowel syndrome or inflammatory bowel disease. ( 5) Plays a Role in a Healthy Heart

For this reason, eating foods rich in vitamin C like kiwis can help promote optimal immune function. Summary Lucas, Jane SA; Lewis, Stella A.; Hourihane, Jonathan O'B (2003).

One type of kiwi allergy called “pollen food syndrome” can cause tingling, swelling, or itching in the lips, mouth, or throat as soon as you eat raw kiwi. These symptoms are usually mild. ( 14) Every year, between March and June, the kiwis undergo a unique mating ritual. After calling out to each other, the pair then meets in the nesting burrow every three days, and while copulating, males emit a distinctive purring sound. The kiwi form close breeding pairs that usually mate for life unless a more desirable partner happens to come along. Fiber, the indigestible part of plant foods, keeps your digestion running smoothly. Kiwi is an excellent source of fiber, with 5 grams in a 1-cup serving. Much of its fiber is in the skin, so just wash and cut — don’t peel — your kiwi. (Yep, it’s OK to eat the fuzzy brown parts!)

Raw kiwifruit contains actinidain (also spelled actinidin) which is commercially useful as a meat tenderizer [44] and possibly as a digestive aid. [45] Actinidain also makes raw kiwifruit unsuitable for use in desserts containing milk or any other dairy products because the enzyme digests milk proteins. This applies to gelatin-based desserts, due to the fact that the actinidain will dissolve the proteins in gelatin, causing the dessert to either liquefy or prevent it from solidifying. Actinidia chinensis (yellow kiwi or golden kiwifruit) has a smooth, bronze skin, with a beak shape at the stem attachment. Flesh colour varies from bright green to a clear, intense yellow. This species is 'sweeter and more aromatic' in flavour compared to A.deliciosa, similar to some subtropical fruits. [18] One of the most attractive varieties has a red 'iris' around the centre of the fruit and yellow flesh outside. The yellow fruit obtains a higher market price and, being less hairy than the fuzzy kiwifruit, is more palatable for consumption without peeling.

Evolving in the absence of most large predators, the kiwi bird fills a similar ecological niche as many land mammals elsewhere, a fact reflected by the kiwi’s anatomy. Like many mammals, their bones are filled with marrow. They rely on their sense of touch and smell. And their soft feathers feel very much like fur. Nevertheless, despite considerable conservation efforts, this animal is in danger of becoming extinct. An Amazing Bird: 4 Kiwi Bird Facts! Hunter DC, Skinner MA, Wolber FM, et al.

Kiwifruit is native to central and eastern China. [1] The first recorded description of the kiwifruit dates to the 12th century during the Song dynasty. [4] In the early 20th century, cultivation of kiwifruit spread from China to New Zealand, where the first commercial plantings occurred. [1] The fruit became popular with British and American servicemen stationed in New Zealand during World War II, and later became commonly exported, first to Great Britain and then to California in the 1960s. [1] [5] Etymology [ edit ] Studies show that diets high in carotenoids may help protect against certain health conditions, including heart disease ( 1, 7). Laboratory findings have indicated that kissper may help manage inflammation in the human intestines. During pregnancy Most kiwifruit sold belongs to a few cultivars of A.deliciosa (fuzzy kiwifruit): 'Hayward', 'Blake' and 'Saanichton 12'. [2] They have a fuzzy, dull brown skin and bright green flesh. The familiar cultivar 'Hayward' was developed by Hayward Wright in Avondale, New Zealand, around 1924. [14] It was initially grown in domestic gardens, but commercial planting began in the 1940s.
