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

Effect of Ionizing Radiation on the Germination‚ Growth and Development of Corn (Zea mays L.) Alexis A. Parco BIO30 Group 1 Sec. A-6L September 27‚ 2012 ABSTRACT Corn seeds pre-exposed to 10‚ 30‚ and 50 kiloRads (kR) of radiation were grown in plots for almost 7 weeks. Four different setups – 10kR‚ 30kR‚ 50kR and the control‚ each with 10 corn seeds initially planted – were observed three times a week (during Mondays‚ Wednesdays and Fridays)‚ and the height of each growing corn was

Question: Does the concentration of salt in the water‚ affects the germination of the seed? Purpose: To see if the salinity of the water affects the germination of the seed‚ before its put into the soil. Back Ground Information: Seed germination is the sprouting or growth of a seed into the start of a plant. When environmental factors such as moisture‚ temperature‚ oxygen‚ and sometimes light are appropriate‚ a viable seed will begin to germinate. Salinity (salt-affected) in plants can

we compared the amount of germinated Raphanus sativus’ in normal and frigid temperatures. My group and I predicted that more seeds in the normal temperature atmosphere would germinate‚ rather than the seeds in the frigid condition. The experiment starts with two petri dishes‚ and we filled each dish with fifty radish seeds. We made our first observations about the seeds that we see. We labeled one petri dish “Control‚” and the other was labeled “Experimental.” The experimental petri dish was put

In this lab the peroxidase enzyme is tested in a dormant avocado seed as well as an avocado seed undergoing the process of germination. A gas pressure will be used to test the seeds and see if the peroxidase enzyme is present in either of the seeds. A catalyst is very similar to track spikes. Spikes increase a runner’s speed‚ as a catalyst speeds up the chemical reaction time in a plant. Neither the catalyst nor shoes are changed in these actions. Enzymes are macromolecules that act like catalysts

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

"To examine the effects of salinty on fenugreek seeds." INTRODUCTION Since the arrival and settlement of European farmers two hundred years ago‚ dryland and irrigated-land salinity have become problematic for the Australian environment‚ despite the fact much of our natural landscape is naturally saline. The response of plants to salinity has been explained as a two-phase growth response. The first phase of growth reduction is characterised by osmotic stress due to salts in the outside solution

PROPOSAL I. PROBLEM What is the role of sunlight on the germination of Vigna radiata (Mung bean) seed? II. TITLE The role of sunlight on the germination of Vigna radiata seed. III. RATIONALE The germination of the seed is a physiological event. The light is one of the most important environmental factors for germination of seeds. The seeds of many species do not germinate in the dark. Vigna radiata seed or Mung bean seed as it commonly called will be used for the study since it can

granted. Without them‚ much of the world would be different and it would affect the planet in a negative manner. 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 throughout the course of fourteen
