have chosen to examine the effects of acidic and basic environments on radish plants (Raphanus sativus)‚ by implementing varying pH levels of buffer solution into the soil. We have allotted a total of four days (Tuesday‚ April 10‚ 2012- Friday April 13‚ 2012) to examine the effects of acid rain. Purpose: To investigate the effect of implementing buffer solutions of varying pH levels in soil on the growth in height of radish plants (Raphanus sativus). Independent Variable: The varying levels of

1. Question: How is the growth rate of bean plants affected by different types of water? 2. Introduction: We are going to be exploring the affect that different type of water have on the growth rate of bean plants. We will be experimenting with two different types of bean plants and testing three different types of water. PH is basically the negative log of hydrogen ion activity used to measure the acidity or basicity. The pH level ranges on a scale from one to fourteen‚ one being most

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

Abstract The seeds of summer squash (Cacurbita moschata)‚ beet (Beta vulgaris)‚ and pepper (Capsicum annuum) are all dicot plants‚ which mean that they have two seed leaves inside the seed coat. When they are placed in an environment and are watered with solutions of different acidic and alkaline levels‚ the root growth during germination is affected. The purpose of this experiment was to observe what type of substance‚ acidic or basic‚ increases the growth of roots during the germination process of

which will help us in my farm’s income. RM6.00/kg Tomato seeds should be started indoors for best germination results. Start the seeds indoors 6 to 8 weeks before the last frost date for your location. Plant 1/4” deep using sterile soil. This helps prevent disease and other problems. The tomato seeds will germinate best if the soil is kept between 80 to 90 degrees. Water lightly and keep the soil consistently moist until germination occurs. When ready to transplant be sure to harden the young

INTRODUCTION TO ASCLEPIAS CALIFORNICA The terrestrial plant‚ Asclepias californica‚ is the primary food source for Monarch butterflies. It can only germinate and produce seeds if provided with the proper environmental influence. The California milkweed’s population is spread out in the southern and coastal areas of California where there are flat lands and grassy slopes. It can also grow up to three feet tall and have clumps consisting of multiple stems that are a couple of feet in width. Unlike
