THE FRUITS OF OUR CHANGING CLIMATE
How Climate Change Affects Fruit Production
INTRODUCTION
GLOBAL: THE APPLE
Apples, one of the most common fruits in the world, according to a study that was published in PLoS One, a peer-reviewed journal, may become more expensive or not possible at all in some areas, due to rising winter temperatures. Evan Girvetz, a Nature Conservancy climate scientist and co-author of the study, says:
“…many fruit and nut trees, such as cherries, apples, apricots, walnuts, and almonds, require cold weather during the winter and early spring time to cue the trees to flower and produce good yields of fruits and nuts. These trees have evolved in areas that freeze, and they go dormant during the

The fact that rising temperatures could make apple trees flower earlier had been shown in previous work. Toshihiko Sugiura, a fruit-tree specialist of the National Agriculture and Food Research Organization in Tsukuba, Japan, and his colleagues Hidekazu Ogawa, Noriaki Fukuda and Takaya Moriguchi, chose to look at how this change affects the quality of the fruit. They then analysed four decades' worth of data gathered from two apple varieties – Fuji, one of the world's leading varieties, and Tsugaru, the second most common in Japan – that were grown in the Nagano and Aomori prefectures, the top two apple-producing regions in Japan.
According to their report that was published on nature.com, the team found during this period of apple cultivation that:
- The annual mean air temperature rose per decade by 0.31°C and 0.34°C in Nagano and Aomori, respectively.
- The dates of bud break and full bloom in both cultivars in both areas advanced earlier by 1.0 – 2.3 days.
- The fruits' acid concentration decreased by 0.16–0.20 g L−1 per decade, firmness by 0.04–0.33 kg and watercore rating by 0.17–0.38, while sugar concentration increased by 0.20–0.28°Brix per decade.
Sugiura stated that these changes may not have been too obvious to consumers as it occurred so gradually over decades, but also has said that “if you could eat an average apple harvested 30 years before
When one considers fruit, there may be bland thoughts of healthy living, diets and the whole nine yard of the dos and don’ts of organic eating. However, when I think of fruits, I feel they are all endowed with a powerful medicinal by-product that is naturally stored within them. Hence my product choice for export. To the Chief operating officer of Investors Inc., I present to you my platform. In the Caribbean, many feel that all fruits are grown on each island in the exact same abundance; this is indeed a myth. Each Caribbean island has its unique crops that are harvested in its soil and grows based on weather conditions. In the Bahamas, the soil is excellent for the growth and harvest of year-round coconuts. Therefore, I plan to use the coconut
Apple trees generally do not begin to blossom and bear fruit until they are 5 to 8 years old. They reach maximum production at about age 20; commercial orchards are generally replaced when they reach 35 to 40 years in age. Although the trees would live longer, the fruit from old trees is generally smaller and poorer in appearance and more expensive to care for. Apple trees can withstand temperatures as low as -40 degrees C. Here in the United States apples mainly grow in Washington, Pennsylvania, New York, Michigan and California. The trees need a period of cold or dormancy to grow and bear fruit properly. So they cannot grow in tropic areas.
Survey, survey was caused mainly because low vitamin C intake, Due to the poor diets at the time, Lots of people were poor, so they couldn’t afford fresh fruit that contained
A predicted increase in global temperatures of 3 C is believed to cause a drastic affect in the quality of life for all things living. Areas that experience more precipitation would be more likely to experience droughts. Due to certain species only being able to evolve and reproduce, their extinction rates could increase because of the changing global temperatures. Probably more of the more interesting aspects are the fact that the sea level would become higher and result in an increase in strong and dangerous hurricanes.
Handfuls of differences come with caring for apple and orange trees, for both are unique species that have totally different needs when it comes to growing them. To start off all different kinds of trees grow better in different climates. The average apple tree is hardyer and can grow in the colder climate with less humidity. However, the orange tree needs a relatively warm temperature year round or it will die because the ground temperature is too cold for it to sustain life. Another issue related to climate is pests and diseases, which has an ability to hinder a tree's growth or even kill it. Since the orange trees live in such a warm environment most of the pest are out of the sun and the diseases are carried off in the breezes there is
The season for fresh fruit is quickly approaching as weather conditions continue to improve. Fresh fruit is a beautiful and exciting way to incorporate important nutrients into the daily diet. Unfortunately, fruit does not stay fresh forever, so it useful to know how to properly preserve fruits to keep them safe and nutritious.
The harvesting phase took place on day 71 and a total of 43 seeds were
Here’s another heroic reason why the apple is the most beneficial fruit in the world; it is now proven that asthma symptoms can be lowered by eating the phenomenal apple. In a study by UK researchers in the American Journal of Respiratory Critical Care Medicine, that adults who are to eat a minimum of two apples a week their asthma risk reduced by one third. A new study which further explains in Thorax, that mothers who ate apples during pregnancy were 27% less likely to have their child suffer from asthma or asthma symptoms until they were five years of age. This happens for a couple of reasons, firstly because an apple’s peel (especially the red ones) contain a lot of antioxidants which help fight against inflammations in the airways. Also
Secondly, when apples turn brown, their appearance does not only change, but the flavor, scent, and nutritional value alters, usually in a bad way. Additionally, when the produce is affected so badly, money is wasted (Gritzer, 2015). It is a fact that American shoppers do not understand the fact that produce tend to bruise, brown, wilt, oxidize, ding, or discolor once and awhile (Chandler, 2016). And, for a four-person American family, the value of discarded produce is averaged to nearly $1,600 a year! (Chandler, 2016). To fix this, there are various ways to reduce the oxidation process in apples (McLandsborough, 2007). Preserving fruits is the best way to save money, especially when there are gardens, fruit trees, berry bushes, and more nearby (Simmons,
Two significant patterns which have occurred due to climate change are temperature and precipitation dispersion. These two patterns strongly correlate which each other and help us to explain processes and therefore implications both socially and economically which are caused from climate change. The earth’s temperature due to climate change is rising; however this temperature rise is not evenly distributed throughout the earth. Inland regions of continental lands masses (excluding the Arctic and Antarctic) heat up far more so than coastal regions, this is because radiation from the sun is these places are high and rock is a poor conductor of heat. Meaning the radiation is only absorbed by the surface. Coastal regions suffer far less from this effect because the ocean conducts heat much more effectively, allowing much more even heating of the ocean and therefore a smaller overall heat increase. The higher levels of heat experienced in the equator due to high sun radiation are an example of how the ocean regulates heat. Through ocean currents this heat is dispersed and is eventually ends up flowing all the way to the poles where its heat energy is released. This means the temperature of coastal regions is far less extreme than inland regions in general. However, because of this temperature regulation throughout the oceans the arctic, Greenland and Antarctic are heating up more rapidly than they otherwise would have. Currents which lead heat energy from the equator are a key
When firstly experienced a mango, I was surprised at the terrific flavor as well as its big size of seed. As the world is globalized on account of development of technology and transportation, even though mango is one of fruits from tropical countries, it is easily introduced to people’s table.
The neo-caloric revolution sprouted during times of energy inefficiency in the early 1900s (Lecture notes, 11/8). Around this time the Fuerte breed was struggling, and around the time of WWII, the ‘Hass’ cultivar was discovered. A Guatemalan seedling variety was introduced by Rudolph Hass who “planted three seedlings in each hole with the idea that the strongest would be grafted and the other two pulled out. The seedlings were to be field-grafted to the popular ‘Fuerte’ variety, but after three attempts, Hass could not get the Fuerte buds to take on one of the seedlings. After the last attempt at grafting, Hass let the seedling tree grow, but the tree was ignored. Hass thought the fruit was ugly, with rough purple-black skin” (Arpaia, Avocado Production in California, 6). From this mistake, the most dominant avocado crop was born. Forty years after its introduction, ‘Hass’ surpassed ‘Fuerte’ in total volume marketed from California. By 1990, ‘Hass’ accounted for 83% of California’s avocado production (vs. only 2% for Fuerte). By the end of the crop year 2010-2011 ‘Hass’ comprised 94.5% of the avocados grown commercially in California” (Arpaia, “Avocado Production in California”,
Besides, the prices of mango are unstable, very expensive during the rainy season and starts to decline in December, the start of the dry season. Mango prices continue to slide down and experienced its lowest at its peak harvest in the month of March and April. The instability of prices for mango is primarily due to an overabundance of produce and short ripening period. Mango is not sun dried due to the following reasons: a) unhygienic (El-Ammin et al., 2006), b) loss of vitamin A and C are excessive by the direct exposure to ultraviolet rays from solar radiation (Madhlopa, Jones, and Kalenga Saka, 2002), and c) due to their high moisture content, drying them to the desired level for safe long storage is a challenge (Achachukwu and Kayode,
Fruit volume, Physiological weight in loss of Kesar ' mango gradually increase till the end of shelf-life and exhibited inversely proportional relationship with specific gravity of fruit while the maximum physiological loss in weight in immature fruits with sp.gr. less than 1.00 as compared sp.gr. more than l.00. Whereas, maximum organoleptic evaluation reported in sp.gr. more than 1.02. Dip treatment of harvested fruits in bavistin 500 ppm for 5 min. had been found to be useful for enhancing the flavour and consumer acceptability. Beneficial effect on minimizing physiological weight loss, maximum fruit volume and firmness in wax coating (6%) followed by bavistin 500 ppm for 5 min. Delay in PLW, maximum fruit volume and firmness with lower organoleptic score were registered at 150C of storage temperature with 85% RH.
Fruit firmness is one of the most important quality variables; it is an indirect measurement of ripeness and its accurate assessment
