Cucurbita Lundelliana
''Cucurbita lundelliana'' is a mesophyte plant species of the genus ''Cucurbita''. It is native to Mexico, Guatemala, and Belize. It has not been domesticated. It is found in the Yucatán region near sea level among limestone cliffs. In Guatemala it is found in Parque Nacional Yaxha Nakum Naranjo along Rio Ixtinto and near Laguna Julequito (west of west end of Lake Yaxha). It has yellow-orange corollas and gray-green seeds. Its leaves are slightly similar to those of '' Cucurbita ficifolia''. It is resistant to powdery mildew and crown rot. In 1962 the first successful cross of a wild ''Cucurbita'' with a domesticated ''Cucurbita'' occurred. In that study by Whitaker, ''C. lundelliana'' was mostly dominant in a cross with '' Cucurbita moschata''. The purpose of the study was to find the ancestral plant species of the domesticated ''Cucurbita''. ''C. lundelliana'' crosses rather well with the five cultivated species of ''Cucurbita''. The species was formally described by Libe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liberty Hyde Bailey
Liberty Hyde Bailey (March 15, 1858 – December 25, 1954) was an American horticulturist and reformer of rural life. He was cofounder of the American Society for Horticultural Science.Makers of American Botany, Harry Baker Humphrey, Ronald Press Company, Library of Congress Card Number 61-18435 As an energetic reformer during the Progressive Era, he was instrumental in starting agricultural extension services, the 4-H movement, the nature study movement, parcel post and rural electrification. He was considered the father of rural sociology and rural journalism. Biography Born in South Haven, Michigan, as the third son of farmers Liberty Hyde Bailey Sr. and Sarah Harrison Bailey. In 1876 Bailey met Lucy Millington who encouraged his interest in botany and mentored him. Bailey entered the Michigan Agricultural College (MAC, now Michigan State University) in 1877 and graduated in 1882 (he had taken a year off from study for health reasons). The next year, he became assistant to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cucurbita Ficifolia
''Cucurbita ficifolia'' is a species of squash, grown for its edible seeds, fruit, and greens. It has common names including Asian pumpkin, black seed squash, chilacayote, cidra, fig-leaf gourd, and Malabar gourd. Compared to other domesticated species in its genus, investigators have noted that samples of ''C. ficifolia'' from throughout its range are relatively similar to one other in morphology and genetic composition. Variations do occur in fruit and seed color, some isozymes, and photoperiod sensitivity. This species is grown widely from Argentina and Chile to Mexico. It is also cultivated in regions of the world including India, Japan, Korea, China, the Philippines, Ethiopia, Kenya, Tanzania, and Angola. No named agricultural cultivars have been recognized. Research suggests that ''C. ficifolia'' represents an earlier evolutionary branch than the other major cultivated ''Cucurbita'' species, but biosystematic investigations have established that ''C. ficifolia'' is n ...

Flora Of Guatemala
According to Parkswatch and the IUCN, Guatemala is considered the fifth biodiversity hotspot in the world. The country has 14 ecoregions ranging from mangrove forest (4 species), in both ocean littorals, dry forests and scrublands in the eastern highlands, subtropical and tropical rain forests, wetlands, cloud forests in the Verapaz region, mixed forests and pine forests in the highlands. Over one third of Guatemala (36.3% or about 39,380 km²) is forested (2005). About half of the forests (49.7% or roughly 19,570 km²) is classified as primary forest which is considered the most biodiverse forest type. Tree species include 17 conifers (pines, cypress, including the endemic '' Abies guatemalensis''), the most in any tropical region of the world. Guatemala has 7 wetlands of international importance that were included in the Ramsar List. Guatemala has some 1246 known species of amphibians, birds, mammals and reptiles according to figures from the World Conservation M ...

Flora Of Belize
The flora of Belize is highly diverse by regional standards, given the country's small geographical extent. Situated on the Caribbean coast of northern Central America the flora and vegetation have been intimately intertwined with Belize's history. The nation itself grew out of British timber extraction activities from the 17th century onwards, at first for logwood (''Haematoxylum campechianum'') and later for mahogany ('' Swietenia macrophylla''), fondly called "red gold" because of its high cost and was much sought after by European aristocracy. Central America generally is thought to have gained much of it characteristic flora during the "Great American interchange" during which time South American elements migrated north after the geological closure of the isthmus of Panama. Few Amazonian elements penetrate as far north as Belize and in species composition the forests of Belize are most similar to the forests of the Petén (Guatemala) and the Yucatán (Mexico).

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cucurbita Moschata
''Cucurbita moschata'' is a species originating in either Central America or northern South America. It includes cultivars known as squash or pumpkin. ''C. moschata'' cultivars are generally more tolerant of hot, humid weather than cultivars of '' C. maxima'' or '' C. pepo''. They also generally display a greater resistance to disease and insects, especially to the squash vine borer. Commercially made pumpkin pie mix is most often made from varieties of ''C. moschata''. The ancestral species of the genus ''Cucurbita'' were present in the Americas before the arrival of humans. Evolutionarily speaking the genus is relatively recent in origin as no species within the genus is genetically isolated from all the other species. ''C. moschata'' acts as the genetic bridge within the genus and is closest to the genus' progenitor. All species of squashes and pumpkins are native to the Western Hemisphere.Victor E.

Crown Rot
A crown is a traditional form of head adornment, or hat, worn by monarchs as a symbol of their power and dignity. A crown is often, by extension, a symbol of the monarch's government or items endorsed by it. The word itself is used, particularly in Commonwealth countries, as an abstract name for the monarchy itself, as distinct from the individual who inhabits it (that is, ''The Crown''). A specific type of crown (or coronet for lower ranks of peerage) is employed in heraldry under strict rules. Indeed, some monarchies never had a physical crown, just a heraldic representation, as in the constitutional kingdom of Belgium, where no coronation ever took place; the royal installation is done by a solemn oath in parliament, wearing a military uniform: the King is not acknowledged as by divine right, but assumes the only hereditary public office in the service of the law; so he in turn will swear in all members of "his" federal government''.

Powdery Mildew
Powdery mildew is a fungal disease that affects a wide range of plants. Powdery mildew diseases are caused by many different species of ascomycete fungi in the order Erysiphales. Powdery mildew is one of the easier plant diseases to identify, as its symptoms are quite distinctive. Infected plants display white powdery spots on the leaves and stems. The lower leaves are the most affected, but the mildew can appear on any above-ground part of the plant. As the disease progresses, the spots get larger and denser as large numbers of asexual spores are formed, and the mildew may spread up and down the length of the plant. Powdery mildew grows well in environments with high humidity and moderate temperatures. Greenhouses provide an ideal moist, temperate environment for the spread of the disease. This causes harm to agricultural and horticultural practices where powdery mildew may thrive in a greenhouse setting. In an agricultural or horticultural setting, the pathogen can be controlle ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Mesophyte
Mesophytes are terrestrial plants which are neither adapted to particularly dry nor particularly wet environments. An example of a mesophytic habitat would be a rural temperate meadow, which might contain goldenrod, clover, oxeye daisy, and ''Rosa multiflora''. Mesophytes prefer soil and air of moderate humidity and avoid soil with standing water or containing a great abundance of salts. They make up the largest ecological group of terrestrial plants, and usually grow under moderate to hot and humid climatic regions. Morphological adaptations Mesophytes do not have any specific morphological adaptations. They usually have broad, flat and green leaves; an extensive fibrous root system to absorb water; and the ability to develop perennating organs such as corms, rhizomes and bulbs to store food and water for use during drought. Anatomical adaptations Mesophytes do not have any special internal structure. Epidermis is single layered usually with obvious stomata. Opening or closing of s ...
