BIOL 1401 General Biology Laboratory Seed Germination Exercise Introduction Seeds are produced by the more advanced plant groups that we will study this semester – Gymnosperms and Angiosperms‚ which are grouped as seeded-vascular plants. While we often take seeds for granted‚ they are remarkable in their physiologies and very diverse in their structure and germination requirements. Seed biology is actually a separate sub-discipline in botany‚ with direct significance to the study of plant ecology

Phytochrome in Lettuce Seed Germination Abstract This experiment was performed to determine the role of phytochrome in lettuce seed germination. In order to conduct this experiment three different types of Grand Rapids lettuce seeds were chosen: Waldmann‚ Concept‚ and Two Star. Each of these seeds were exposed to the following regulated courses of light exposure for ten minutes after they had imbibed for five minutes: Red‚ White‚ Far Red‚ and Darkness. It was hypothesized that the seeds would germinate

affect the germination of seeds. Most factors are external but there are also some internal conditions that affect the germination of seeds‚ even though this is quite rare. The most common and the most important external conditions and factors that affect the germination of seeds are oxygen‚ water‚ temperature and also in some cases light or darkness. Some plants require several variables for successful seed germination. As this is quite rare‚ this often depends on the individual seed and its natural

Factors Affecting Seed Germination Research Question What is the effect of dark and light on the germination of radish seeds? Hypothesis I predict the seeds grown in the light will germinate twice as much as the ones grown in the dark. Materials/Setup Paper towels 2 petri dishes 10 radish seeds Water Plastic container A weight A folded piece of paper Procedure 1. Take a paper towel and cut out two circles that are the same size as the base of the petri dishes. 2. Wet

15 Problem: Can water float on water? Introduction: Can water float on water some say ye because ice can float but we are talking about water on top of water. The salt water and fresh will have different effects on the experiment. The experiment also see if the warmer the water is the different way it look. Purpose: The reason that I am doing this project is to see if water can float on water and to see the water at different densities‚ and salinity. To see if the salt water would sit on the

The Germination of Seeds of the Native Plant Acacia decurrens Practical Report Biology 1 Introduction: In a botanical sense‚ “germination is the process of emergence of growth from a resting stage.” (http://encyclopedia.laborlawtalk.com/germination). Under favourable conditions‚ the seed begins to germinate‚ and the embryonic tissues resume growth‚ developing towards a seedling. Soils from a Cumberland Plain Woodland community were investigated to determine the presence of a soil seed-bank;

Germination of Mustard Seeds using Fertilisers 1. Abstract This study was done to look at the effects of fertilisers and identify which fertiliser produced the fastest results. Four types of fertilisers were used over a four-week period and the findings were that inorganic fertilisers enhanced seed germination rates. 2. Introduction Fertilisers are widely used in agricultural production because they contain essential compounds such as phosphorus‚ nitrogen and potassium that have been depleted

SALT WATER Introduction: Salt water refers to water that contains dissolved salts‚ known as saline water or seawater‚ water from oceans or seas. It is a home to varieties of aquatic animals‚ for example‚ fishes and snails. Some of these animals find it difficult to live in fresh water. If salt water animals go to live in fresh water they can not adapt the environment led to die to them. This essay aims to discuss the importance of salt water and the sub- types namely ocean‚ sea‚ and coral reefs

experiment is designed to test the allelopathy of two different treatments‚ Eucalyptus (Eucalyptus cinerea) and Lemon (Citrus limon). The two treatments will be tested on radish seeds (Raphanus sativus) to investigate the effect of the treatments on the germination of the radish seeds. Allelopathy is the beneficial or harmful effects that one plant has on another plant by the release of chemicals. Allelopathy studies the interactions among plants‚ fungi‚ algae and bacteria with the organisms living in
