Introduction This 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

INTRODUCTION A seed is a fertilized ovule that contains an embryo and transforms it into a new plant through the process of germination. Seeds remain inactive until conditions are right for germination. All seeds need water‚ oxygen‚ and proper temperature in order to germinate. However‚ some seeds require full light or darkness to germinate. According to Holm (1996) seeds have chemical inhibitors that prevent germination. A seed will not grow unless those inhibitors are destroyed by things like

temperature affect radish germination. The original hypothesis was if temperature affects the tail length of the germinated seed‚ then a higher temperature will lead to a significant decrease in the tail length of the germinated seed. This hypothesis is true‚ according to the collected data. After 6 days of letting the seeds germinate‚ the ones that germinated in room temperature were quicker to germinate and with a lot more tail length compared to the ones in the incubator. In fact‚ the seeds from the incubator

The Difference Between Onion Red Rum Bunching Seeds Germinating at 70 degrees compared to 40 degrees. Abstract Researchers tested the germination of Red Rum Bunching Seeds in different temperatures. Research shows that depending on the seed germination is most likely to occur at a higher temperature rather than a colder one. According to the results the germination rate for seeds at room temperature was 96% compared to seeds in the fridge which germinated at 0% Review of Literature According

The Effects of a Seed Coat in Seed Germination Mario Monroe INT1 Task 3 The Effects of a Seed Coat in Seed Germination Abstract Seed germination is an important aspect in plants growth and food production. It is therefore it’s of uttermost importance to know the effective ways of seed germination so as to improve food production. This research was therefore prompted by the rising issue of farmers buying low quality and a damaged maize seed from unscrupulous sellers and this has led to deterioration

A seed is an embryonic plant that is enclosed in a seed coat or some kind of protection (Seed‚ 2009). A seed is the basis for any plant life; it is the essential beginning for any sort of growth. A seed is created from a previous plant or two plants pollinating with each other to create a seedling (Seed‚ 2009). Typically there are three main parts of a seed: an embryo‚ nutrients for the embryo‚ and a seed coat (Seed‚ 2009). The embryo is the true essential of the seed. It contains the one cotyledon

A seed consists essentially of a seed coat‚ stored food and a young plant‚ the embryo. The seed coat may be made of inner tegmen and outer testa. On the seed coat a scar (hilum) is present which shows the place of attachment of a seed in the fruit is present. At one end of the hilum is the micropyle. Through micropyle the seed absorbs water during the process of germination. The embryo consists of epicotyl‚one or two seed leaves called cotyledons‚ and a hypocotyle. The portion of the embryo above

Seed Germination Some people‚ when they think of germination‚ think of a seed sprouting. Very plain‚ simple image in their mind‚ especially since there is so much more going on in the small seed. New Life is growing. Germination is the sprouting of a seed‚ through which a lot of plants reproduce‚ though not all. Water is a major trigger in the germination stage‚ playing a major role also later in the plant’s life. Though seeds are not the only way for plants to reproduce‚ it is one of the easiest

Bioassay of Radish Seeds Bioassay is a type of scientific experiment used in the development of new drugs and monitoring pollutants. It estimates the potency of a substance‚ by testing its effect on living matter. In other words‚ it determines how much of the substance is needed to poison an individual‚ without testing it on any humans or animals. From here the TC50 of the substance can be adjusted for dealing with humans and animals over plants. In this lab we attempted to find the potency of

ON LACTUCA SATIVA L. GERMINATION Introduction The time that a seed germinates‚ and whether or not it actually does germinate‚ depends on many factors. These factors include; the chemical environment‚ which must be the right conditions; oxygen must be present‚ and inhibitory chemicals must not be present. Germination also depends on the physical environment. Temperatures must be suited to the seed‚ and light quality and quantity must also be suited to the needs of the seed. In some cases‚ all these
