2. LITERATURE REVIEW 2.1 Origin and Distribution Tannia was originated in tropical America, but currently grown widely as a subsistence food crop in Asia, Africa and Polynesia (Bown, 2000). From five crops which are under sub family aroid the only tannia originated from Central & South America others originated from South-east Asia (Lebot, 2009). When the Europeans arrived, it was further known to have been grown from Southern Mexico to Bolivia in the Latin America. Only during the 19th century,
Arabidopsis Culture Cell and Transformation Arabidopsis thaliana (L.) Columbia ecotype suspension- cultured T87 cells were maintained at 22°C in JPL3 medium with continuous illumination and shaking at 100g. Two-week-old cells were sieved through 500 μm stainless mesh and the remaining filtrate was transferred to a flask containing 20 ml of fresh JPL3 medium for subculture. Transformation of T87 cells was done by culturing the cells in B5 medium supplemented with 1 μM 1-naphthaleneacetic acid (NAA)
honeybee’s means of communication there was no change in the number or diversity of the pollen types that each colony collected each day(Donalson, et al, 2013). The group originally hypothesized that communication would focus all or the majority of the colonies foraging efforts on a highly productive natural pollen resource. Instead, the group found that impairing dance communication resulted in the honeybees returning with rare novel pollen types instead of foraging on the same pollen resource types
Maize C.N: 20 (Diploid) Kingdom: Plantae Division: Magnoliophyta Class: Liliopsida Order: Poales Family: Poaceae Genus: Zea Species: Z. mays Introduction: Maize, is the world's 3rd leading cereal crop, following wheat and rice. USA produces nearly 40% of the total world’s production and it is also the staple food of Americans. After the America, largest corn producing country, are the People's Republic of China & Brazil. Corn is the leading cereal in USA, with ordinary production 3 times
of leaflets with rachis ending in a terminal leaflet. Leaflets are ovate to elliptic, 0.6-2.0 cm long, 0.3-1.4 cm wide; margin serrate, apex acuminate to aristate, base cuneate; stipules 2-5 toothed or absent. The inflorescence consists of solitary flowers, sometimes 2 per inflorescence and borne on 0.6-3 cm long peduncles, 7-10 mm long calyx; while the bracts are triangular or tripartite; the corolla is 0.8-1.2 cm long and varies
The pigweed is a quickly evolving weed in the farming industry. Scientifically, this plant is known as Amaranthus palmeri S. Watson. Amaranthus comes from the Greek for evergreen or unfading. This plant was first described by Sereno Watson in the late 1800s. However, it was named after Edward Palmer, who actually discovered the plant earlier in the same century. This is where the palmeri of Amaranthus palmeri was derived. The pigweed is also known by other names such as, Carelessweed and Palmer’s
1954). Virola theiodora is a slender tree, 25-75 feet in height, with a cylindrical trunk up to 1.5 feet in diameter and smooth, brown-mottled bark with gray patches. Staminate inflorescences are many- flowered, paniculate, usually shorter than leaves, up to 15 cm long (usually shorter). Pistillate inflorescences are shorter. Distribution is mainly in the western Amazonia of Brazil and Columbia, possibly also in adjacent parts of Peru and Venezuela: especially abundant in the Rio Negro basin
veins. It should be easy to distinguish between rough and annual blue grass by the lack of prominent light lines and glossy abaxial surface of rough blue grass and the multiple light lines and light green appearance of annual blue grass. The inflorescence also varies between the three. Kentucky blue grass has an open pyramid shaped panicle. Rough blue grass has an open panicle. Annual blue grass has a small open panicle and seeds are present through most of the season and are most abundant during
Zingiber officinale, referred to commonly as ginger or garden ginger, is a member of the Zingiberaceae family. It is a plant of vital importance due to the variety of derivatives that can be produced and utilized. Ginger’s diverse therapeutic capabilities for the body have contributed to healthcare dating back to ancient civilizations and continue to evolve with modern science as more in-depth means of observation are focused on its composition and potential capabilities. In addition, by-products
Orchidaceae, the second largest plant family, is the most diverse and highly evolved amongst angiosperms which constitute about 40% of the monocotyledonous taxa. The recent taxonomical studies imply that distinctly named varietal number of orchids fall very close to a total of 19,000 comprising 800 genera and 25,000 species (Lahaye et al., 2008). Orchids mostly comprise of epiphytes whose greatest diversity occurs in tropical and sub-tropical regions. India has a rich heritage of wild orchids in
3 years. The staminate and pistillate of Sweetgum is monoeciouse. The small, greenish flowers bloom from march to early May, depending on latitude and weather conditions. Both the staminate and pistillate flowers occur in heads. The staminate inflorescences are racemes; the solitary pistillate flowers are globose heads that that form the multiple head, 2.5 to 3.8cm in diameter, of small, two-celled capsule. The lustrous green color of the fruiting heads fades to yellow as maturity is reached in September
in great numbers around the world. The members of these class are also usually woody plants and the flowers tend to be symmetric and with both stamen and carpels (Encyclopaedia Britannica). A distinctive trait to the genus is that the fruit is inflorescence in the sense that inside a fig, there are a number of flowers and seeds that compose it (Kline 2011). Because of the layout, it is important that seed dispersal is biotic. The opening of the fig is called the ostiole and it is so small that only
The Orchidaceaeis a diverse and widespread family of flowering plants with blooms. And Dendrobium is a huge genus of orchids which have most marketing value among other orchids in the world. Orchids with their bewildering range of flowers and beautiful color combinations provide a source of profound aesthetic pleasure to both owners and visitors. The striking resemblances of their flowers to various forms of animal life behold the attention of everyone who looks at them. Orchids are excellent item

Bamboo Gramineae, the grass family, has provided civilization throughout history with a bounty of food and many other uses. The top three economically important plants of the world are grasses: wheat corn, and rice. Human kind probably would not have survived if not for the grasses. The sub-family Bambusoideae, is certainly no exception. These are the bamboos. Consisting of 75 genera and over 1000 species, these unique plants have played a diverse and important role in the development of society
time. Orchids have evolved in various ways, primarily mimicry, that increases their reproductive success, as well as influence the evolution of other insects that mimic them. Most flowers are limited to attracting insects only with their bright inflorescences and fragrance, but orchids have evolved another tactic. Some flowers in the Orchidaceae family utilize a pseudo-copulation method where they mimic insects of the opposite sex for pollination. In addition, orchids have evolved even further to releasing
The Extraordinary Olive The several uses of the olive tree, Olea europaea L., have long been recognized and celebrated by human civilization. Olive trees have been cultivated since prehistoric times in Asia Minor, and introduced with human migration and trade throughout the Mediterranean and Europe, into Africa, and eventually into New Zealand and North America. Thomas (1995) lists the beginning of olive cultivation as aproximately 3000 B.C. Olives appear in one of the first cookbooks ever discovered
Purple Loosestrife is a plant with diverse qualities. It blooms profusely and in the past has been loved by many for its ornamental value. More recently it is drawing attention to itself for outcompeting native species and altering the landscape of wetlands throughout the world. In examining this perennial herb, turned weed, we will learn where it came from, where it grows and the impact it has had on North American ecosystems. We will also review control methods, both successful and unsuccessful
