PEACHES AND (WINGS OF THINGS PHOTO BLOG)




Hi Everybody!!
I hope everyone is enjoying Spring Break. I am having a busy Spring helping a friend write something, but if the sun comes out, I am outside among the new flowers planting more. The warmth is bringing out the bees. Your photostudy tonight is of 'the previously covered in ice' Peach Tree Blossoms. And here to show off his new Spring Wings is JerryBuzz (formerly babybuzz last summer). Of course, I have shared some info from Wikipedia below. Let Spring come in to your heart. Enjoy!

Peach

From Wikipedia, the free encyclopedia

The peach (Prunus persica) is a deciduous treenative to North-West China, in the region between the Tarim basin and the north slopes of the Kunlun Shan mountains, where it was first domesticated and cultivated. [2] It bears an edible juicy fruit also called a peach. The species name persica refers to its widespread cultivation in Persia, whence it was transplanted to Europe. It belongs to the genus Prunus which includes the cherry and plum, in the family Rosaceae. The peach is classified with the almond in the subgenus Amygdalus, distinguished from the other subgenera by the corrugated seed shell.
Peaches and nectarines are the same species, even though they are regarded commercially as different fruits. In contrast to peach whose fruits present the characteristic fuzz on the skin nectarines are characterized by the absence of fruit skin trichomes (fuzz-less fruit); genetic studies suggest nectarines are produced due to a recessive allele, whereas peaches are produced from a dominant allele for fuzzy skin.[3]
China is the world's largest producer of peaches and nectarines.

Cultivation[edit]

Peaches grow very well in a fairly limited range, since they have a chilling requirementthat low altitude tropical areas cannot satisfy. In tropical and equatorial latitudes, such as EcuadorColombiaEthiopiaIndia and Nepal, they grow at higher altitudes that can satisfy the chilling requirement.[14][15] The trees themselves can usually tolerate temperatures to around −26 to −30 °C (−15 to −22 °F), although the following season's flower buds are usually killed at these temperatures, leading to no crop that summer. Flower bud kill begins to occur between −15 and −25 °C (5 and −13 °F), depending on the cultivar (some are more cold-tolerant than others) and the timing of the cold, with the buds becoming less cold tolerant in late winter.[16]
Typical peach cultivars begin bearing fruit in their third year and have a lifespan of about 12 years. Most cultivars require between 600 and 1,000 hours of chilling; cultivars with chilling requirements of 250 hours (10 days) or less have been developed enabling peach production in warmer climates. During the chilling period, key chemical reactions occur before the plant begins to grow again. Once the chilling period is met, the plant enters the so-called quiescence period, the second type of dormancy. During quiescence, buds break and grow when sufficient warm weather favorable to growth is accumulated. Quiescence is the phase of dormancy between satisfaction of the chilling requirement and the beginning of growth.[17]
Certain cultivars are more tender, and others can tolerate a few degrees colder. In addition, intense summer heat is required to mature the crop, with mean temperatures of the hottest month between 20 and 30 °C (68 and 86 °F). Another problematic issue in many peach-growing areas is spring frost. The trees tend to flower fairly early in spring. The blooms often can be damaged or killed by frosts; typically, if temperatures drop below about −4 °C (25 °F), most flowers will be killed. However, if the flowers are not fully open, they can tolerate a few degrees colder.[citation needed]

Cultivars[edit]

There are hundreds of peach and nectarine cultivars. These are classified into two categories—the freestones and the clingstones. Freestones are those for whom the fruit flesh separates readily from the pit. Clingstones are those for whom the flesh clings tightly to the pit. Some cultivars are partially freestone and clingstone, and these are called semi-free. Freestone types are preferred for eating fresh, while clingstone for canning. The fruit flesh may be creamy white or deep yellow; the hue and shade of the color depends on the cultivar.[18]
Peach breeding has favored cultivars with more firmness, more red color, and shorter fuzz on fruit surface. These characteristics ease shipping and supermarket sales by improving eye appeal. However, this selection process has not necessarily led to increased flavor. Peaches have short shelf life, so commercial growers typically plant a mix of different cultivars in order to have fruit to ship all season long.[19]
Different countries have different cultivars. In United Kingdom, for example, the following cultivars have gained the Royal Horticultural Society's Award of Garden Merit:-
  • 'Duke of York'[20]
  • 'Peregrine'[21]
  • 'Rochester'[22]
  • 'Lord Napier' (nectarine)[23]

Planting[edit]

Most peach trees sold by nurseries are cultivars budded or grafted onto a suitable rootstock. This is done to improve predictability of the fruit quality.
Peach trees need full sun, and a layout that allows good natural air flow to assist the thermal environment for the tree. Peaches are planted in early winter. During the growth season, peach trees need a regular and reliable supply of water, with higher amounts just before harvest.[24]
Peaches need nitrogen rich fertilizers more than other fruit trees. Without regular fertilizer supply, peach tree leaves start turning yellow or exhibit stunted growth. Blood mealbone meal, and calcium ammonium nitrate are suitable fertilizers.
The number of flowers on a peach tree are typically thinned out, because if the full number of peaches mature on a branch, they are under-sized and lacking in flavor. Fruits are thinned midway in the season by commercial growers. Fresh peaches are easily bruised, and do not store well. They are most flavorful when they ripen on the tree and eaten the day of harvest.[24]
The peach tree can be grown in an espalier shape. The Baldassari palmette is a palmette design created around 1950 used primarily for training peaches. In walled gardens constructed from stone or brick, which absorb and retain solar heat and then slowly release it, raising the temperature against the wall, peaches can be grown as espaliers against south-facing walls as far north as southeast Great Britain and southern Ireland.

Wing

From Wikipedia, the free encyclopedia
wing is a type of fin with a surface that produces aerodynamic force for flight orpropulsion through the atmosphere, or through another gaseous or liquid fluid. As such, wings have an airfoil shape, a streamlined cross-sectional shape producing a useful lift to drag ratio.
The word "wing" from the Old Norse vængr[1] for many centuries referred mainly to the foremost limbs of birds (in addition to the architectural aisle.) But in recent centuries the word's meaning has extended to include lift producing appendages of insectsbats,pterosaursboomerangssome sail boats and aircraft, or the inverted airfoil on a race car that generates a downward force to increase traction.
Various species of penguins and other flighted or flightless water birds such as auks,cormorantsguillemotsshearwaterseider and scoter ducks and diving petrels are avid swimmers, and use their wings to propel through water.[2]
A wing's aerodynamic quality is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitudegreater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift.
