Almonds
The almond (''Prunus amygdalus'', syn. ''Prunus dulcis'') is a species of tree from the genus ''Prunus''. Along with the peach, it is classified in the subgenus ''Amygdalus'', distinguished from the other subgenera by corrugations on the shell ( endocarp) surrounding the seed. The fruit of the almond is a drupe, consisting of an outer hull and a hard shell with the seed, which is not a true nut. ''Shelling'' almonds refers to removing the shell to reveal the seed. Almonds are sold shelled or unshelled. Blanched almonds are shelled almonds that have been treated with hot water to soften the seedcoat, which is then removed to reveal the white embryo. Once almonds are cleaned and processed, they can be stored for around a year if kept refrigerated; at higher temperatures they will become rancid more quickly. Almonds are used in many cuisines, often featuring prominently in desserts, such as marzipan. The almond tree prospers in a moderate Mediterranean climate with cool ...

Almond Cultivation In California
California produces 80% of the world's almonds and 100% of the United States commercial supply. Although almonds are not native to California, a hot, dry Mediterranean climate and developed water infrastructure create favorable conditions for commercial cultivation of the crop. In 2020, there were devoted to almond farming in California, producing . Almonds are the state's most valuable export crop. Farmers exported $4.9 billion worth to foreign countries in 2019, about 22% of the state's total agricultural exports, with the European Union, China and India as leading destinations. California almond farms import the majority of US commercial bee colonies to the state of California during the almond pollination season. Almond production in California is the source of several major environmental problems, including high demand for water and abundant waste of almond shells. As of 2021, due to a historic long-term drought in California, production was forecast to decline, and many a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus
''Prunus'' is a genus of flowering plant, flowering trees and shrubs from the family (biology), family Rosaceae. The genus includes plums, cherries, peaches, nectarines, apricots and almonds (collectively Drupe, stonefruit). The genus has a cosmopolitan distribution, being native to the temperate regions of North America, the neotropics of South America, and temperate and tropical regions of Eurasia and Africa, There are about 340 accepted species . Many members of the genus are widely cultivated for their sweet, fleshy fruit and for decorative purposes of their flowers. ''Prunus'' fruit are drupes, or stone fruits. The fleshy Fruit anatomy, mesocarp surrounding the Fruit anatomy, endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel"), which is edible in some species (such as sweet almonds), but poisonous in many others (such as apricot kernels). Besides being eaten off the hand, m ...

Marzipan
Marzipan is a confectionery, confection consisting primarily of sugar and almond meal (ground almonds), sometimes augmented with almond oil or extract. It is often made into Confectionery, sweets; common uses are chocolate-covered marzipan and small marzipan imitations of fruits and vegetables. It can also be used in biscuits or rolled into thin sheets and glazed for icing cakes, primarily birthday cakes, wedding cakes and Christmas cakes. Marzipan may also be used as a baking ingredient, as in stollen or banket (food), banket. In some countries, it is shaped into small figures of animals as a traditional treat for New Year's Day or Christmas. Marzipan is also used in Roscón, Tortell, and in some versions of king cake eaten during the Carnival season. Around the world Europe The Geographical indications and traditional specialities in the European Union recognize two marzipans in Europe: one in Toledo (Spain) and one in Lübeck (Germany).

Climate Change In California
Climate change in California has resulted in higher than average temperatures, leading to increased occurrences of droughts and wildfires. Over the next few decades in California, climate change is predicted to further reduce water availability, increase wildfire risk, Effects of climate change on agriculture, decrease agricultural productivity, and threaten coastal ecosystems. The state could also be impacted economically due to the rising cost of providing water to its residents along with revenue and job loss in the agricultural sector. Economic impacts also include inflation from rising Climate change and insurance in the United States, insurance premiums, Carbon price, energy costs and food prices. California has taken a number of steps to mitigate impacts of climate change in the state. Paleoclimatological evidence Paleoclimatology, Paleoclimatological studies indicate that the last 150 years of California's history have been unusually wet compared to the previous 2000 ye ...

Droughts In California
The historical and ongoing droughts in California result from various complex meteorological phenomena, some of which are not fully understood by scientists. Drought is generally defined as "a deficiency of precipitation over an extended period of time (usually a season or more), resulting in a water shortage." A lack of rainfall (or snowfall) or precipitation in meager quantities, higher than average temperatures and dry air masses in the atmosphere commonly underlie drought conditions; these natural factors are further complicated by increases in populations and water demands. Since the California water supply is attained from numerous sources, fulfilled by varied and intricate weather patterns, there is no one cause of drought. California is not only the most populous state and largest agricultural producer in the United States, it is also the most biodiverse; as such, drought in California can have a far reaching economic and environmental impacts. There are five major ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batsch
August Johann Georg Karl Batsch (28 October 1761 – 29 September 1802) was a German naturalist. He was a recognised authority on mushrooms, and also described new species of ferns, bryophytes, and seed plants. Life and career Batsch was born in Jena, Saxe-Weimar to George Lorenz Bratsch and Ernestine (''nee'' Franke) Bratsch. He studied at the Jena City School, and then had private tuition. He showed an aptitude for natural sciences and drawing, and so subsequently studied medicine and philosophy at the University of Jena (now known as the Friedrich Schiller University of Jena), entering in 1772 and obtaining his doctorate in philosophy in 1781 and in medicine in 1786, his supervisor being Justus Christian Loder. Batsch was married in 1787 to Amalie Pfaundel. They had three children, Friedrich (born 1789), George Friedrich Karl (1792), and Karoline (1795). He died in 1802 after a short illness. In 1786 Batsch began to teach natural history at the University of Jena and in 1787 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twig
A twig is a thin, often short, branch of a tree or Bush (plant), bush. The buds on the twig are an important diagnostic characteristic, as are the abscission scars where the leaves have fallen away. The color, texture, and patterning of the twig bark (botany), bark are also important, in addition to the thickness and nature of any pith of the twig.Alan Crivellaro and Fritz Hans Schweingruber There are two types of twigs: vegetative twigs and fruiting spurs. Fruiting spurs are specialized twigs that generally branch off the sides of branches and are stubby and slow-growing, with many annular dendrochronology, ring markings from seasons past. The twig's age and rate of growth can be determined by counting the winter terminal bud scale scars, or annular ring marking, across the diameter of the twig. Uses Twigs can be useful in starting a Campfire, fire. They can be used as wikt:kindling, kindling wood, bridging the gap between highly flammable tinder (dry grass and leaves) and ...

Deciduous
In the fields of horticulture and botany, the term deciduous () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed Leaf, leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their Leaf, leaves for part of the year. This process is called abscission. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the Plant stem, stem. It is able to twist the leaf to face the sun, producing a characteristic foliage arrangement (spacing of blades), and also optimizing its exposure to sunlight. Outgrowths appearing on each side of the petiole in some species are called stipules. The terms wikt:petiolate, petiolate and wikt:apetiolate, apetiolate are applied respectively to leaves with and without petioles. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be Sessility (botany), sessile or apetiolate. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaves
A leaf (: leaves) is a principal appendage of the stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper ( adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax, and other features. Leaves are mostly green in color due to the presence of a compound called chlorop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
