Determinate Growth
In biology and botany, indeterminate growth is growth that is not terminated in contrast to determinate growth that stops once a genetically pre-determined structure has completely formed. Thus, a plant that grows and produces flowers and fruit until killed by frost or some other external factor is called indeterminate. For example, the term is applied to tomato varieties that grow in a rather gangly fashion, producing fruit throughout the growing season, and in contrast to a determinate tomato plant, which grows in a more bushy shape and is most productive for a single, larger harvest, then either tapers off with minimal new growth or fruit, or dies. Inflorescences In reference to an inflorescence (a shoot specialised for bearing flowers, and bearing no leaves other than bracts), an indeterminate type (such as a raceme) is one in which the first flowers to develop and open are from the buds at the base, followed progressively by buds nearer to the growing tip.

Spathoglottis Flwrs Reduced
''Spathoglottis'', commonly known as purple orchids or 苞舌兰属 (bao she lan shu) is a genus of about fifty species of orchids in the family Orchidaceae. They are evergreen terrestrial herbs with crowded pseudobulbs, a small number of leaves and medium-sized resupinate flowers on an upright flowering stem. The sepals and petals are all similar to each other and are white, yellow, pink or purple. Species of ''Spathoglottis'' are found from eastern and south-eastern Asia to Australia and some Pacific Islands. Description Orchids in the genus ''Spathoglottis'' are evergreen, terrestrial herbs with crowded pseudobulbs just below the surface of the soil and a few large, pleated leaves. The flowering stem emerges from a pseudoblulb and bears medium-sized, colourful flowers. The flowers open widely with the sepals and petals all similar in size to each other, although with the petals usually broader, the sepals are hairy on the outside. The labellum has three lobes, the side lobes m ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica'') and radish (genus ''Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A compou ...

Determinate Cultivar
Tomato and potato cultivars are commonly classified as determinate or indeterminate according to the amount of time that they produce new leaves and flowers. Varieties that produce few leaves and flowers over a shorter period are classed as determinate and those that produce new leaves and flowers for longer are classed as indeterminate. Tomatoes Determinate, or bush, types bear a full crop all at once and top off at a specific height; they are often good choices for container growing. Determinate types are preferred by commercial growers who wish to harvest a whole field at one time, or home growers interested in canning. Indeterminate cultivars develop into vines that never top off and continue producing until killed by frost. They are preferred by home growers who wish ripe fruit throughout the season. As an intermediate form, there are plants sometimes known as "vigorous determinate" or "semi-determinate"; these top off like determinates but produce a second crop after the init ...

Cantharellus Californicus
''Cantharellus'' is a genus of popular edible mushrooms, commonly known as chanterelles, a name which can also refer to the type species, ''Cantharellus cibarius''. They are mycorrhizal fungi, meaning they form symbiotic associations with plants, making them very difficult to cultivate. Caution must be used when identifying chanterelles for consumption due to lookalikes, such as the jack-o'-lantern mushroom (''Omphalotus olearius'' and others), which can make a person very ill. Despite this, chanterelles are one of the most recognized and harvested groups of edible mushrooms. Many species of chanterelles contain antioxidant carotenoids, such as beta-carotene in ''C. cibarius'' and ''C. minor'', and canthaxanthin in ''C. cinnabarinus'' and ''C. friesii''. They also contain significant amounts of vitamin D. The name comes from Greek κάνθαρος, ''kantharos'' 'tankard, cup'.

Daucus
''Daucus'' is a worldwide genus of herbaceous plants of the celery family Apiaceae of which the best-known species is the cultivated carrot. ''Daucus'' has about 25 species. The oldest carrot fossil is 1.3 Ma, and was found on the island of Madeira in the Atlantic Ocean. Description Members of ''Daucus'' are distinguished within the family ''Apiaceae'' by their leaves which are 2–3 pinnatisect with narrow end sections. The genus primarily consists of biennial plants but also includes some annual plants and some perennial herbs. All ''Daucus'' have bristly stems. The inflorescences are umbels. The flowers are mostly white, with bracts and bracteoles. The petals may be pure white, reddish, pinkish or yellowish. They are emarginate above and have pointed, wrapped lobules. The petals are often unequal in size, with petals at the outermost edge of the inflorescence often being larger. The fruit is an ovoid to ellipsoidal schizocarp, cylindrical or compressed, with ciliate pri ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Allium
''Allium'' is a genus of monocotyledonous flowering plants that includes hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. The generic name ''Allium'' is the Latin word for garlic,Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 43 and the type species for the genus is '' Allium sativum'' which means "cultivated garlic".''Allium'' In: Index Nominum Genericorum. In: Regnum Vegetabile (see ''External links'' below). Carl Linnaeus first described the genus ''Allium'' in 1753. Some sources refer to Greek ἀλέω (aleo, to avoid) by reason of the smell of garlic. Various ''Allium'' have been cultivated from the earliest times, and about a dozen species are economically important as crops, or garden vegetables, and an increasing number of species are important as ornamental plants. The decision to include a species in the genus ''Allium'' is taxonomically difficult, and spec ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and p ...

Tomato
The tomato is the edible berry of the plant ''Solanum lycopersicum'', commonly known as the tomato plant. The species originated in western South America, Mexico, and Central America. The Mexican Nahuatl word gave rise to the Spanish word , from which the English word ''tomato'' derived. Its domestication and use as a cultivated food may have originated with the indigenous peoples of Mexico. The Aztecs used tomatoes in their cooking at the time of the Spanish conquest of the Aztec Empire, and after the Spanish encountered the tomato for the first time after their contact with the Aztecs, they brought the plant to Europe, in a widespread transfer of plants known as the Columbian exchange. From there, the tomato was introduced to other parts of the European-colonized world during the 16th century. Tomatoes are a significant source of umami flavor. They are consumed in diverse ways: raw or cooked, and in many dishes, sauces, salads, and drinks. While tomatoes are fruits ...
