Plant Biology
Objectives/Goals The project purpose was to determine whether the number of stomata on a leaf's surface affects volume of water transpired in 24 hours. After testing environmental effects on…
Plant Biology
Objectives/Goals The objective of our project was to determine how usable forms of nitrogen and symbiosis inhibit or encourage plant growth. We believed that plants with usable nitrogen woul…
Plant Biology
Objectives/Goals To determine whether or not applying a low concentration of salicylic acid (SA) to green bean plants will reduce any damaging effects caused by exposure to salt water stress…
Plant Biology
Objectives/Goals To determine whether acid rain deters the antibacterial component of garlic Methods/Materials Acid rain was applied on one group of garlic plants and another group of garlic…
Plant Biology
Objectives/Goals To analyze the response of Cd Tolerant Arabidopsis mutants in terms of their root growth, shoot growth and Cd accumulation. Methods/Materials Root Assay: I grew Mutants and…
Plant Biology
Objectives/Goals The objective is to determine if the time a cover crop is allowed to grow will affect its ability in enhancing the growth of a target plant grown in the same soil afterwards…
Plant Biology
Objectives/Goals The objective was to evaluate the relationship between the phytonutrient I3C, found in Cruciferous vegetables, and estrogen in the soil, and to show if estrogen in the soil…
Plant Biology
Objectives/Goals To learn if gibberellic acid has any effect on the salt tolerance of Pisum sativum macrocarpon. Methods/Materials 125 P. sativum seedlings were cultivated for 11 weeks in so…
Plant Biology
Objectives/Goals I conducted this experiment to find out the effect of Hydrogen Peroxide (H(2)O(2)) on the rooting of plant cuttings and seed germination. Methods/Materials I used two sets o…
Plant Biology
Objectives/Goals The objective of my project is to determine why the ice plant grows over the salt grass but stops at the pickleweed near the edge of the channels in the Ballona Wetlands. Th…
Plant Biology
Objectives/Goals The objective is to find how the temperature of the water that is given to radishes affects their growth. Methods/Materials Three identicle plastic pots and filled with MIri…
Plant Biology
Objectives/Goals The purpose of this project is to observe how much negative tropism, due to wind (Thigmotropism) is too great for the positive tropism, phototropism. Methods/Materials Four…
Plant Biology
Objectives/Goals I believe that both plants, epipremnum aureum and plectranthus verticillatus, will be stunted or halt totally in root growth when placed in a container containing either aci…
Plant Biology
Objectives/Goals The objective of this project was to find the effects of ash on radish plants. Methods/Materials The experimenter used ash from Julian, California; potting soil; Burpee radi…
Plant Biology
Objectives/Goals In my project I investigated the effects of different amounts of light energy on plant growth. Methods/Materials My four light treatments were 0 Watts, 4 Watts, 25 Watts, an…
Plant Biology
Objectives/Goals The objective was to determine the growth effects of various light sources: incandescent, fluorescent, and natural sunlight on lima bean seedlings. I propose that plants gro…
Plant Biology
Objectives/Goals I plan to examine the contrasting results in plant growth, development, and health, as well soil pH and nitrogen concentration that result from the use of organic and inorga…
Plant Biology
Objectives/Goals My objective was to study how temperature and pH affect the germination and early growth of Mung Beans. Methods/Materials My experiment was done in 2 groups, temperature and…
Plant Biology
Objectives/Goals The purpose of this experiment was to evaluate the growth pattern of corn plants when limiting critical macronutrients in hydroponic growing solutions. My hypothesis is that…
Plant Biology
Objectives/Goals My objective is to reduce the amount of material necessary to make Andros spring wheat herbicide resistant by showing that the use of the GFP gene could simplify the process…
Plant Biology
Objectives/Goals To investigate the conservation of gene function among plant species, the translatability of two, morphology-governing genes, BREVIPEDICELLUS LIKE (BPL) and NO APICAL DOMINA…
