Plant Biology
Objectives/Goals The objective of my project was to determine if location in an orchard effected the sugar levels in Navel oranges. Methods/Materials Randomly collected Navel oranges from si…
Plant Biology
Objectives/Goals The purpose of this years experiment is to build on the previous four years work on presoaking of cottonseed before planting. This years project is to see if presoaking cott…
Plant Biology
Objectives/Goals My objective was to find out what temperature of water would leach the tannins out of acorns using the least amount of water. Methods/Materials First, I gathered, cracked an…
Plant Biology
Objectives/Goals An experiment was set up to test the effect of burned soil on seed germination. Soil samples were collected from five sites, each one varying in burn history. The most recen…
Plant Biology
Objectives/Goals My objective is to utilize cuttings from various fruit trees and grafting them to root stocks to bring them out of the dormant stage with the use of artificial light and hom…
Plant Biology
Objectives/Goals My objective is to determine the effects of artificial gravity, ultraviolet light, and magnetic field on seed germination and the growth of the root. I believe that artifici…
Plant Biology
Objectives/Goals One of the main problems today is that people are running short on water. I have the answer for you; it is called gray water recycling. My project is the affects of gray wat…
Plant Biology
Objectives/Goals The objective of this experiment was to determine if different types of light affects the growth of plants. It was hypothesized that if a plant is grown under a light that c…
Plant Biology
Objectives/Goals The purpose of the project was if water storing granules (Rain Drops) helps to conserve water, while still being able to observe substantial growth in Perennial Ryegrass, Be…
Plant Biology
Objectives/Goals This project investigates how light affects the time it takes for phototropism to take place in plants. My project consitsted of seven cups, which were filled with 3 inches…
Plant Biology
Objectives/Goals The objective of this experiment was to determine if a hybrid tree, consisting of the fast-maturing Golden Dorsett's stock with popular Granny Smith scions grafted onto it,…
Plant Biology
Objectives/Goals The aim of the project was to determine how different concentrations of saline solution affect the growth of buttercrunch lettuce (Latucia sativa) seeds. Methods/Materials F…
Plant Biology
Objectives/Goals My project was to determine the effect of fertilizers on plants grown in various soil types. Methods/Materials A total of 96 radish plants were grown from seed. The project…
Plant Biology
Objectives/Goals The objective was to determine the most drought resistant grass. I believed that Annual Ryegrass would grow the best, and prove to be the most drought resistant grass. Metho…
Plant Biology
Objectives/Goals The objective was to determine whether or not crezacin, a synthetic plant adaptogen, would improve the germination rate, growth and/or weight of pole bean plants. Methods/Ma…
Plant Biology
Objectives/Goals I tried to show that there is a pattern for the new Valley Oak trees that are growing in an abandoned Walnut tree orchard in a city park. Methods/Materials I counted young V…
Plant Biology
Objectives/Goals When using legumes which raises the nitrogen level in the soil more, nitrogen-fixing bacteria or nitrogen fertilizer? Methods/Materials I enoculated alfalfa plants with thre…
Plant Biology
Objectives/Goals This project was done to determine if nutrient uptake efficiency affects the growth of plants, specifically corn (Zea mays) and wheat (Poacease triticum). Nutrient uptake ef…
Plant Biology
Objectives/Goals The goal of my project was to find the link between an orange's internal ethanol conditions and its external rind stress. I believe that the Wax category will do the best be…
Plant Biology
Objectives/Goals The objective of my experiment was to test the pH levels of the water used to nurish the plants and find out the different effects on the plants. Methods/Materials Two diffe…
Plant Biology
Objectives/Goals The purpose was to discover how plants use the different colors of light that are all present in white light. The plants will grow under a single color light to see which co…
Plant Biology
Objectives/Goals The Objective of my project was to find if the size of the seed determines the ideal planting depth. Methods/Materials Six types of legume seeds were obtained and the weight…
Plant Biology
Objectives/Goals To see if plants can growth faster or slower in soil without microorganisms. Methods/Materials Materials: 36 zinnia seeds soil (unbaked) soil (baked to kill off microorganis…
Plant Biology
Objectives/Goals The major purpose of this experiment was to determine if the zoospores produced by p. ramorum search for hosts after making contact with water. The secondary purpose of this…
Plant Biology
Objectives/Goals The objective of this study was to find the amount of nitrogen that is taken up by both grasses and legumes. Methods/Materials The first thing that was done was growing the…
Plant Biology
Objectives/Goals To find the effect of the salinity of water on seed germination. Methods/Materials 1 packet of lettuce seeds, 1 packet of radish seeds, 1 packet of paper coffee filters, ten…
Plant Biology
Objectives/Goals To investigate whether the mass of a pinto bean affects the height of its plant. I believe that the beans with a larger mass will grow taller plants. Methods/Materials The f…
Plant Biology
Objectives/Goals I wanted to find out how various levels of biuret in urea fertilizer affect citrus leaves, specifically in relation to toxic effects. I also wanted to find out how different…
