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

affect the growth (mass) and germination of individuals of two species growing alone and in mixed species groups. Hypothesis: If planted like treatment 1 (8 collards) and 4 (8 radish) then it will have a higher mass and a greater germination percentage. If the plant is planted with a smaller population density and has intraspecific competition then the radish and collard will have higher germination percentages and mass averages. Constants: Pots‚ temperature‚ soil‚ seeds‚ amount of light‚ water Independent

scientists believe that germinating radish seeds give off a chemical that interferes with the germination of other seeds. A few years ago‚ a group of scientists published a scientific paper that demonstrated that germinating radish seeds have an allelopathic effect upon lettuce seeds. A year later‚ another group of botanists repeated the experiment. The second group claimed that the radish seedlings had no allelopathic effect upon lettuce seed germination or growth. Now it is your turn to determine

plant’s ability to inhibit germination or growth of the surrounding germination. In our exercise‚ we tested for the presence of allelopathic chemicals in plant shoots and the effect of the allelopathic chemicals (our I.V.) on the germination and growth (our D.V.) on radish seeds. The question proposed became‚ “Does Rose seed extract affect the germination and growth of radish seeds?” Keeping the allelopathic effects in mind‚ our working hypothesis became‚ “If radish seeds get exposed to the rose leaf

Introduction There are about a million different kinds of seeds in our world with all of the different types of plants that we have. One type of seed that takes between three to five days to germinate is a daikon radish. The radish (Raphanus sativus ) originated from China. It was commonly seen and eaten by the people of Egypt long before the Egyptians started to construct their very own pyramids. Later on‚ radishes became a common vegetable to eat in Greece‚ and since the radish meant so much worth

Zea mays L. Ten seeds for each level of gamma radiation (0 krad‚ 10 krad‚ 30 krad and 50 krad) were planted and tested for the number of germinating seeds and plant height‚ using a meter stick or ruler. Data were collected for 30 days period and graphs and figures of the data were analyzed. Therefore‚ it can be inferred that the level of gamma radiation introduced to the plant would have adverse effect on the growth of corn plant; in terms of plant height‚ number of germinating seeds and its over-all

Introduction Seed germination and growth are influenced by many factors. Some of these are the environment‚ light quality and moisture availability. Other factors which may influence seed germination are a result of the environment surrounding the seed‚ like alleleopathy. In this experiment we are going to study the alleleopathy of garlic. Using the scientific method of inquiry‚ my group and I are experimenting if the volatility of the crushed garlic will affect germination and growth of the

100 – 05 ALLELOPATHY INTRODUCTION The purpose of this lab was to observe the effects of chemical warfare among plants. Plant seeds compete with other plants and seeds‚ for sunlight‚ and nutrients in order to germinate. In order to win dominance over other seeds‚ and reduce competition‚ plants produce and release a chemical in order to prevent other seeds from germination. This type of chemical warfare is referred to as allelopathy. Allelopathy exists in many parts of the plants such as leaves‚

plants experiment‚ each group received the F1 generation seeds for their designated phenotypes. After receiving the seeds‚ the seeds were then planted into Styrofoam “quads” allowing the seeds to germinate. The seeds were then allowed to grow under a fluorescent light bank for 5 weeks. Throughout the growing of the seeds‚ each plant was continuously watered and adjusted the light bank to help the plant grow more efficiently. After letting the seeds germinate for approximately 14 days‚ after two or three
