Abstract The purpose of this lab was to see if radiation has an effect on the cultivated radish seeds that we used. From the observed data that we collected‚ we were able to conclude that when seeds are exposed to radiation‚ it affects how they grow‚ if there is any growth at all. Introduction Radiation is an important environmental abiotic factor for plants‚ and one small section of the electromagnetic radiation spectrum‚ is called the Photosynthetically Active Radiation (PAR)‚ provides

"To examine the effects of salinty on fenugreek seeds." INTRODUCTION Since the arrival and settlement of European farmers two hundred years ago‚ dryland and irrigated-land salinity have become problematic for the Australian environment‚ despite the fact much of our natural landscape is naturally saline. The response of plants to salinity has been explained as a two-phase growth response. The first phase of growth reduction is characterised by osmotic stress due to salts in the outside solution

six different branches and six different types of apples. The more common way to reproduce is sexual reproduction. In order for this to happen gametes must be produced and fertilized. Seeds‚ fruits‚ and embryos must also be developed. The two main advantages of reproducing this way are new genetic combinations and seeds spread over a large area. The following are the reproductive parts in this process. The first part is the flower‚ which has four types of modified leaves. The first one is the sepal

concentration of Miracle Gro was ideal for the germination of seeds. I hypothesized that the 1.25% concentration of Miracle Gro would allow the plant to grow the fastest‚ unfortunately‚ my data does not support my hypothesis. According to the information we collected‚ the amount of concentration with the fastest speed and greatest height of growth was the 0% with plain tap water (control group). Two days after “planting‚” my group measured the seed with the greatest rate of growth: 0% exhibited 2.5 cm of

in class is to see whether or not competition between plants for water and sunlight will affect their growth. To do this we will set up two pots with soil in them‚ one will have a radish seed inside and the other will have a radish seed surrounded by crest seeds. The independent variable will be the amount of seeds in each pot and the dependent variable will be the height of each radish at the end of the experiment. The constant factors will be the amount of sunlight each pot receives; this will be

ripening and the list goes on. Besides‚they also have high market value which will help us in my farm’s income. RM6.00/kg Tomato seeds should be started indoors for best germination results. Start the seeds indoors 6 to 8 weeks before the last frost date for your location. Plant 1/4” deep using sterile soil. This helps prevent disease and other problems. The tomato seeds will germinate best if the soil is kept between 80 to 90 degrees. Water lightly and keep the soil consistently moist until germination

withstand long periods of drought. It has a long taproot and can withstand high temperatures during the summer. Ber is a multipurpose tree (see Appendix 1). The fruit is the most well-known and used product from the tree‚ however it is also a source of seeds‚ timber‚ fodder‚ medicines and potential industrial components. Ber trees can compensate local farmers after subsistence crops have been harvested‚ giving a potential economic return in local markets when food is scarce. The fruits harvested 3-4

Practical Research & Report Assessment. Allelopathy and interference and the effect they have on plant growth. Allelopathy occurs in plants. Many plants produce chemicals that may be harmful or beneficial to other plants. In some cases a species can produce chemicals that can prevent the growth or germination of another species. An example of this is Australian native plants such as Casuarinas and Eucalypts which produce allelochemicals that prevent competition of other plants. This is a form of

lab we used the plants grass and clover. We then used the three liquids with each of the types of plants. Materials and Methods: In this lab many materials were used. Among them are perlite‚ greensand‚ rhizobium‚ urea‚ water‚ clover seeds‚ grass seeds‚ a marker‚ a ruler‚ a beaker‚ a test tube rack‚ plastic wrap‚ a teaspoon and a pencil. The first thing we did was to measure the half point of all the test tubes with a ruler and mark them with a marker. Then we labeled each test tube with the
