This is Mendel¡¦s First Law-the Law of Segregation. This experiment investigated the effects of complete and incomplete dominance on the behavior of two different genes for chlorophyll production in tobacco. Two sets of approximately 50-100 tobacco seeds were planted for one week. The plants were the F2 result of two sets of monohybrid F1 crosses Gg x Gg and CyCg x CyCg. A chromosome for these plants has two sets of genes. The gene at one locus has two alleles that code for normal chlorophyll production

Do Radish Seedlings Produce Allelopathic Chemicals? Do you ever feel that you need your own space? When you feel you want to get away from other people‚ you can walk away or leave the room. Plants and trees need their own space in order to obtain sufficient amounts of nutrients from the soil and sunlight. Plants‚ of course‚ are unable to move away. However‚ some plants use chemicals to keep other plants from growing too close. This process is called allelopathy. Some scientists believe that germinating

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 radish seeds

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 for the Greeks‚ they

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

were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle length. Our data indicated that seed germination decreased as concentration increased‚ demonstrated

Growth of the Rapid Grow Radish‚ Brassica rapa ABSTRACT Mycorrhizae can be described as a symbiotic relationship between a fungus and a plant where both the fungus and the plant benefit from this interaction. Endomycorrhizae and ectomycorrhizae are the two main types of mycorrhizae that produce the same overall results‚ but with 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
