How sodium chloride concentration affects the germination‚ growth and development of Brassica rapa. Osumi‚ K.‚ Nihei‚ B.‚ Takanishi‚ K.‚ Nakamura‚ C.‚ Warehime‚ R. Period 2. 03/05/17 Introduction: To have a successful germination‚ the plant seed needs a sufficient amount of water and oxygen present. Other conditions include room temperature‚ and the amount of light intake. Hydration of a seed‚ is an essential step for seed germination (Martínez-Andújar‚ 2014). Plants tend to germinate better in

different fungal characteristics. This study examines the effects of mycorrhizae on the growth of the rapid-grow radish‚ Brassica rapa. Germination rates and flowering rates of the plants were observed to determine if the mycorrhizal treatment benefitted the growth of the radish. The mychorrizal inoculum was found to have a positive effect on the earlier onset of germination and flowing. INTRODUCTION Mycorrhizal fungi are ubiquitous in terrestrial ecosystems‚ forming a symbiotic association with roots

a species can produce chemicals that can prevent the growth or germination of another species. An example of this is Australian native plants such as Casuarinas and Eucalypts which produce allelochemicals that prevent competition of other plants. This is a form of a defence mechanism in order to survive. A negative effect of Allelopathy includes Patterson’s Curse. Patterson’s curse releases allelochemicals that inhibit the germination and growth of other plants. When plants are competing they compete

varying seed sizes between each. Testing both nonnative and native species was important to the understanding of the impact that leachates from species that historically share and area‚ and species that have had no history of interaction‚ had on germination. The differing seed sizes allowed for a better understanding of the Biochemical Recognition Hypothesis‚ due to the known differences between small and large seeds. Small seeds are typically less provisioned than larger seeds‚ have a longer soil

The Effects of Household Detergent on Germination and Biomass Production of Pinto Beans and Radishes Introduction and Background: Plants are a diverse kingdom that gives vital sources of food‚ energy‚ and oxygen to sustain life on the planet. Plant classification is divided into four major groups including mosses and liverworts‚ ferns‚ conifers‚ and flowering plants. Plants we most commonly identify ourselves with is edible fruits and vegetables. There are a variety of types of vegetables from

and growth (in cm)‚ germination‚ and survival rate was measured. Results showed that at the right level of radiation level (10 kR)‚ radiation have a positive effect on the plant growth and has the same germination and survival rate from the control set up. The 30 kR set up and 50 kR set up are relatively smaller in growth than the control set up. Thus‚ increasing the radiation level above 10 kr corn inhibits its growth in terms of height and decreases the percent germination ofcorn (Zea mays L.)

Therefore‚ it is necessary for plants to be able to grow. In this paper‚ there is information on seed germination and light’s effects on plants. These are important part of seeds’ growth and they were a part of the experiment that was performed and then analyzed in this paper. The experiment tested the color of light’s effect on an Alaskan pea plants’ growth

Water is imperative for the growth and preservation of life‚ especially plants. Playing a role from the vary beginning‚ water is necessary in the germination of dry seeds and growth of plants throughout their life cycle. However‚ there are drawbacks to an overabundance of water or a lack of water. Therefore‚ how much water is required to maximize the potential of a given crop? In our experiment‚ we examine the effects of water on corn. Corn is a vital crop to North America‚ and there is a wide draw
