effect on radish seed germination rates? 2. Does exposure to such radiation have a measurable effect on radish seedling growth? 3. If you can demonstrate any effect‚ is it dependent on the level of radiation exposure? 4. Do individuals in the population exhibit variations in their tolerance to radiation exposure? First Hypothesis: Ho: Seed germination has nothing to do with gamma radiation (50‚ 150‚ and 500) HA: Gamma radiation will have an effect on seed germination Second Hypothesis:

Botany online 1996-2004. No further update‚ only historical document of botanical science! Gibberellins In 1926 studied the Japanese E. KUROSAWA a rice disease that is known as the ‘foolish seedling’-disease in Japan. The plants grow extremely fast‚ look spindly and pale and break off easily. KUROSAWA detected that the reason for this abnormal growth is a substance that is secreted by a parasitic fungi (Fusarium moniliforme = Gibberella fujikuroi). It was termed gibberellin. During the thirties

highly concentrated form that that is potent and highly effective. What it does: - induces the closure in stomata to prevent transpiration and water loss - prevents fruit ripening - promotes seed dormancy by stopping cell growth and seed germination -stops synthesis of Kinetin nucleotide -Kinetin: cytokinin that promotes cell division -down regulate enzymes needed for photo synthesis -dials down growth to levels just needed for survival to prevent water loss Where

Introduction: The world’s total forest area is just over 4 billion hectares‚ which corresponds to an average of 0.6 ha per capita (Figure 1). The five most forest-rich countries (the Russian Federation‚ Brazil‚ Canada‚ the United States of America and China) account for more than half of the total forest area. Deforestation – mainly the conversion of tropical forest to agricultural land – shows signs of decreasing in several countries. Around 13 million hectares of forest were converted to

The Effect of Salinity on Seed Germination 1) Abstract: Poor seeding growth can be the result of soil salinity. A study was done to examine the influence of NaCl salinity treatment on the germination and seeding grow of vigna radiata using different NaCl concentration 0 (control) ‚ 0.25 ‚ 0.5 ‚ 1.0 ‚ 1.75 . A graph was used to analyze the data obtained from the study. Important differences among the treatment were indicated as a result of this study. The germination percentage of vigna radiata

The purpose of my experiment is to determine the effect of acid rain on seed germination. I chose this idea for a project because I have heard that acid rain is becoming a more prominent factor‚ around the world‚ due to pollution. I see reports of this in books and websites I ’ve visited‚ as well as news articles I have read.

concentrations on the growth of the seed roots. This served to give us a cheap and quick way to experience a bioassay experiment from our classroom. Hypothesis I believe that a greater concentration of NaCl will correlate with a lower seed germination rate‚ as well as a shorter radicle length. Procedure 1. Label petri dishes with the appropriate concentration levels and place filter paper in each dish. 2. Treat each dish with 2mL of the appropriate concentration of the

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 by our dramatic difference between the percentage of seeds germinated in our control group (0%) and the percentage of seeds germinated
