In agriculture and gardening‚ hybrid seed is seed produced by cross-pollinated plants. In hybrid seed production‚ the crosses are specific and controlled. The advantage of growing hybrid seed compared to inbred lines comes from heterosis. To produce hybrid seed‚ elite inbred varieties are crossed with well-documented and consistent phenotypes (such as yield) and the resulting hybrid seed is collected. Another factor that is important in hybrid seed production is the combining ability of the parent

Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel‚ who had studied peas‚ did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

Cloning is asexual reproduction. Cuttings are taken from a mother plant in vegatative growth‚ and rooted in hydroponic medium to be grown as a separate plant. The offspring will be plants that are identical to the parent plant. Cloning preserves the character of your favorite plant. Cloning can make an ocean of green out of a single plant‚ so it is a powerful tool for growing large crops‚ and will fill a closet quickly with your favorite genetics. When you find the plant you want to be your "buddy"

PLANT RESPONSES TROPISM is a biological phenomenon‚ indicating growth or turning movement of a biological organism‚ usually a plant‚ in response to an environmental stimulus. In tropisms‚ this response is dependent on the direction of the species. The word tropism comes from the Greek trope ("to turn" or "to change"). Tropisms are usually named for the stimulus involved and may be either positive (towards the stimulus) or negative (away from the stimulus). Phototropism is the growth response

It is said that life comes from the forest‚ it is an area of land where flora and fauna are present. But because of different human activities‚ it started to become endangered. Therefore‚ Singapore made a greenhouse where different types of plants

Abstract: Having study natural selection and artificial selection we wanted to select for a trait on the plant Brassica rapa. We hypothesized that the leaf density is heritable and veritable. After our experiment we were able to conclude that our hypothesis was refuted because our average leaf density in our daughter population increased. Introduction: We are artificially selecting for a trait in the plant Brassica rapa. ( Wisconsin Fast Plant). Brassica rapa has been artificially selected

Monteverde is located in Puntarenas‚ Costa Rica‚ an approximately four-hour journey from the Central Valley. Costa Rica is known for its diverse variety of flora and fauna. Among them‚ Orchids are one of the main attraction. The majority of orchids in Costa Rica are found in Monteverde Orchid Gardens. The Garden alone accommodates over 500 species of orchids from a wide range of color and shape. Monsoon is said to be the best season of the year for orchids. A countless number of tourists and naturalists

Gestural movements are incorporated throughout Jardi Tancat. One of the motifs include ‘sowing’ or seed planting action‚ which involves a low‚ curved line of the spine again to emphasize the straining work. Hunched over with a slumped dynamic
