Sexual Plant Reproduction: Testing conditions required for pollen germination and tube growth ____________________________________________________________________________ File: pollen Modified from E. Moctezuma & others for BSCI 442 (Sze) Objectives: Get familiar with the parts of flowers: male and female organs Observe pollen germination and tube growth in real time. Test the conditions that stimulate pollen germination and tube growth. Observe cytoplasmic streaming (due to vesicle traffic)

varying seed sizes between each. Testing both nonnative and native species was important to the understanding of the impact that leachates from species that historically share and area‚ and species that have had no history of interaction‚ had on germination. The differing seed sizes allowed for a better understanding of the Biochemical Recognition Hypothesis‚ due to the known differences between small and large seeds. Small seeds are typically less provisioned than larger seeds‚ have a longer soil

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

and growth (in cm)‚ germination‚ and survival rate was measured. Results showed that at the right level of radiation level (10 kR)‚ radiation have a positive effect on the plant growth and has the same germination and survival rate from the control set up. The 30 kR set up and 50 kR set up are relatively smaller in growth than the control set up. Thus‚ increasing the radiation level above 10 kr corn inhibits its growth in terms of height and decreases the percent germination ofcorn (Zea mays L.)

Therefore‚ it is necessary for plants to be able to grow. In this paper‚ there is information on seed germination and light’s effects on plants. These are important part of seeds’ growth and they were a part of the experiment that was performed and then analyzed in this paper. The experiment tested the color of light’s effect on an Alaskan pea plants’ growth

sort Michigan Pea Beans (now called Navy beans). Since that time‚ sorters have been adapted to sort/separate many different products‚ including seed‚ fresh and cooked food products‚ snack items‚ minerals‚ plastics‚ etc. Basically‚ any dry particulate solid that requires visual inspection and can be accelerated to a common speed and singulated (i.e.‚ placed in a row so they can be viewed one by one)‚ is a good candidate for color sorting. Many large crop seed such as peas and beans differ in color between

ABSTRACT Exposure of corn plants to ionizing radiation such as gamma radiation can induce mutation. The purpose of this study was to

Water is imperative for the growth and preservation of life‚ especially plants. Playing a role from the vary beginning‚ water is necessary in the germination of dry seeds and growth of plants throughout their life cycle. However‚ there are drawbacks to an overabundance of water or a lack of water. Therefore‚ how much water is required to maximize the potential of a given crop? In our experiment‚ we examine the effects of water on corn. Corn is a vital crop to North America‚ and there is a wide draw

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
