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

Temperature Effects on Radish (Raphanus sativus) Root Development Abstract Several studies have been conducted to establish how temperature‚ seed germination‚ and root growth are related. Because temperature plays a main role in many growth processes‚ we decided to focus on how it affected root growth. Radish (Raphanus sativus) seeds were chosen due to their ability to produce a distinct bulbous tuber‚ and their relatively short growing time. Three test groups were placed under different temperature

The Effect of Varying Dosages of Gamma Radiation on the Growth of Corn (Zea mays L.)1 Montalbo‚ Josephine M. A- 1L September 7‚ 2013 1 A scientific paper submitted in partial fulfillment of the requirements in Genetics laboratory under Prof. Cheryl D. Agdaca‚ 1st semester‚ A.Y. 2013-2014. ABSTRACT Exposure of corn plants to ionizing radiation such as gamma radiation can induce mutation. The purpose of this study was to

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. LITERATURE REVIEW http://www.selah.k12.wa.us/soar/sciproj99/CodySciProj.html The germination test results from glass labeled “Trial 1” (100% water)‚ and “Trial 5” (highest

alkaline levels‚ the root growth during germination is affected. The purpose of this experiment was to observe what type of substance‚ acidic or basic‚ increases the growth of roots during the germination process of Cacurbita moschata‚ Beta vulgaris‚ and Capsicum annuum. Previous research has shown that water with a rather neutral pH level of 7 is best for plant germination and growth and that pH levels more acidic or basic did not show much plant germination. The hypothesis was that if the acidity

Investigating 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)

Florencia Rodriguez October 20‚ 2010 IB Biology SLII The effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans Research Question: What is the effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans? Independent Variable: The different pH levels in the water would be the independent variable in this lab. Three different pH levels were tested‚ 4‚ 7 and 10‚ both 4 and 10 were chosen because they are 3 pH levels away

removed the seeds from the pod. To start the germination process‚ a moistened piece of filter paper was placed into a petri dish. 40 seeds were neatly placed into each petri dish until there were no seeds remaining. Once all the seeds were placed in the petri dish‚ the petri dishes were placed in a plastic bag and set to germinate for approximately 48 to 96 hours in the window at room temperatures.

Prakash was briefed that the shade nets would prevent virus causing pests to enter the structure‚ the portray reduce the root damages in seedlings; decrease excess water retention at base and the media which is light weight would promote excellent germination and growth. As expected‚ he got quality seedlings which were very much in demand. He slowly started to grow seedlings in the ancestral land and today the full 2 ½ acre is under quality vegetable seedling production. | | Realizing the need
