Plant Biology
Objectives/Goals California Senator Dean Florez stated, "In your previous research Buckeye trees seem to have been effective in eliminating mosquitoes." He then asked me, "How easy would it…
Plant Biology
Objectives/Goals My objective was to determine how Hydroponic and Aeroponic growing systems compare to traditional soil based technology in terms of water consumption, root vigor, and growth…
Plant Biology
Objectives/Goals My objective is to test if there was higher mortality of Pinyon Pines on steeper slopes and on hotter slopes (south aspect) during the last drought. Steeper slopes have grea…
Plant Biology
Objectives/Goals Does the amount of light affect the germination of spinach seeds? Methods/Materials Spinach seeds were planted in individual "cells" in a styrofoam getminating tray. To crea…
Plant Biology
Objectives/Goals My objective was to determine which of four pre-planting treatments to lettuce seed would cause the seed to germinate the fastest. The four pre-treatments I used were: pre-w…
Plant Biology
Objectives/Goals The live oak tree is a large part of the native California landscape. Live oak seedlings are found to be limited when the oak woodlands community is examined. A member of th…
Plant Biology
Objectives/Goals For those people who have lots of plants, buying fertilizers can be expensive. The purpose of my experiment was to make homemade fertilizers and compare them with commercial…
Plant Biology
Objectives/Goals This study was conducted to increase the production of Vitamin C in leafy lettuces without genetic manipulation. Methods/Materials For eight months, 224 leafy lettuces (Gran…
Plant Biology
Objectives/Goals This project deals mostly with photoperiodic responses of mung bean plants when exposed to amounts of light to dark varying from 8 hours of artificial light and 16 hours dar…
Plant Biology
Objectives/Goals The objective of my study was to see if mustard plants could be used for phytoremediation of Zinc. Methods/Materials To study whether zinc can be phytoremdiated, mustard pla…
Plant Biology
Objectives/Goals Determine whether or not fertilizer added to garden soil will contribute to a greater harvest. Evaluate two types of organic fertilizer - chicken and steer manure. Methods/M…
Plant Biology
Objectives/Goals The objective of my project was to determine which of four hay crops--barley, oats, vetch, or peas--is most tolerant of saline soils. Methods/Materials The different seed ty…
Plant Biology
Objectives/Goals There are many countries in the world that suffer from infertile or salty soil. This can drastically affect the citizens ability to grow food crops. The basis for this proje…
Plant Biology
Objectives/Goals The main purpose of this project was to show why corn is planted and at certain times of the year. If you plant at the wrong time then it takes longer for the crop to grow o…
Plant Biology
Objectives/Goals I wanted to find out how temperature affects a plant's ability to transport nutrients. From my research, I learned that transpiration and respiration increase as temperature…
Plant Biology
Objectives/Goals The objective was to test how the intensity of artificial light affected the growth of sunflower plants. My hypothesis was that the plants closest to the light will grow the…
Plant Biology
Objectives/Goals I want to determine if there is one color that can be used to paint our cherry trees that will protect them from sunburn without causing harvest delays. Methods/Materials My…
Plant Biology
Objectives/Goals My project was to determine if bean plants grew stronger and healthier by the addition of the right amount of sugar to their watering. I believe that plants that receive 50…
Plant Biology
Objectives/Goals The objective of my experiment was to see how the timing of the application of potassium affects plant growth. Methods/Materials There were four groups of twelve plants each…
Plant Biology
Objectives/Goals To find if the plant growth in poppies and bush pea plants is affected by the application of aluminum, zinc, or iron sulfate; and to find if plants grow and germinate faster…
Plant Biology
Objectives/Goals The goal of this project was to analyze the effects that a parasitic fungus and a mutualistic fungus would have on tomato plants', as well as Bacopa plants', growth, develop…
Plant Biology
Objectives/Goals My project objective was to determine the tolerance of different salinity levels from diluted ocean water on rice seedlings growth. Methods/Materials Purified drinking water…
Plant Biology
Objectives/Goals The purpose of this study was to determine if Gossypium barbadense c.v. pima S-6 exposed to low, medium, and high levels of ozone would affect the G. barbadenses' roots and…
Plant Biology
Objectives/Goals The experiment was done by comparing Kentucky bluegrass, or Poa pratensis and measuring how it grew in pure humus, or potting soil and a mixture of pure humus and sand. Meth…
Plant Biology
Objectives/Goals Is plant food production affected by different wavelengths of light? My hypothesis is that the plant under the green filter, which only allows green wavelengths through, wil…
Plant Biology
Objectives/Goals This experiment had two objectives. 1. The first objective was to determine whether plants could survive in a simulated Martian-like environment. 2. The second was to find w…
Plant Biology
Objectives/Goals The objective of my project was to determine which soaking solution would germinate bean seeds most effectively. As a higher percentage of seeds successfully germinate, crop…
Plant Biology
Objectives/Goals This study examined the question of which type of soil pea plants grew better in- sterile, sterile with nitrogen fertilizers, or untreated soil. Methods/Materials A total of…
Plant Biology
Objectives/Goals The purpose of this project is to find out which factor is most important for plant growth: sunlight, water, or good quality soil. We made a hypothesis that water is the mos…
Plant Biology
Objectives/Goals Farmers and florists have been trying to uncover the secret to creating crops with strong flowers. Abrupt weather conditions and unknown nutrient deficiencies have been trou…
