Germination of Eggplant, Okra and Rice Seeds Soaked in Alkaline Water

In a plant’s life cycle, there are a few key details such as germination, growth, egg or sperm production, pollination, seed production and dispersal, and finally death. In the germination phase the seed sprouts after a certain exposure to light, temperature, and moisture (Pima Community College). In the growth stage the sprout turns into a mature plant, this is followed by the production of an egg or sperm and then pollinated by other pollen transferred by the wind or an animal. Next is the seed production when the embryo and endosperm get a seed coat to form a new seed, the dispersal of the seed occurs it is transferred from the parent by interaction with an animal. Finally death, it’s pretty obvious, death is when the plant dies.

The experiment was begun by obtaining four 8 oz. Styrofoam cups and punching a hole through the bottom of them. This hole was for water entry or excess water drainage. Moistened soil was packed to the 1/2 full line in the cup along with 3 fertilizer pellets The cups were labeled the following: Rosette-H20, Rosette-GA, Wild-Type-H2O, and Wild-type- GA.(Handout 1) A small wooden applicator stick was obtained a moistened at the tip with water from the petri dish labeled ‘water.’ This was to be able to attract the seed to the applicator in order to place the seed from its original container into

The purpose of this experiment is to observe the effects of Sodium Chloride (NaCl) on the germination rate of Wisconsin Fast Plants.

The seeds soaked in the salt solution did not have any change in appearance while the seeds exposed to the vinegar solution generally appeared to become darker in color and shriveled. For the 10% fertilizer solution only one replication produced germination (6 out of the 10 seeds in the petri dish germinated). The seeds that did not germinate for the 10% fertilizer solution appeared darker in color. Seeds exposed to distilled water (control) had germination across every replication group and produced some fairly large sprouts. The 10% soap solution seeds also had germination in every replication group, but the size of the sprouts were not as large as the ones in the control group.

Firstly, for the setup of the experiment, two styrofoam cups were filled with two inches worth of standard, fertilized garden soil, next four seeds from from the garden seed, and the bird seed were placed an inch deep in separate cups. The seeds were blindly labeled, with one being labeled group A and one being labeled group B. This was so as to efficiently conduct a double blind experiment. The seeds were watered with approximately a teaspoon of water per day, and kept in a sunny windowsill. They were left in the windowsill for two weeks, and watered daily.

In order to test this hypothesis and prediction, an experiment was conducted using a heterozygous F1 generation of Brassica Rapa seeds. The seeds were planted, pollinated, harvested (F2 generation) and germinated for observation. When leaves were visible, phenotypes (green vs. purple) were counted and recorded. The experiment took place over 13 weeks, spanning the full semester of General Biology Lab I. The sections that follow will detail the materials and methods used, the results of the investigation and an in-depth discussion of the outcomes.

The basic plant life cycle with alternation of generations is modified in angiosperms by the change of haploid (n) and diploid (2n) generations, which take turns making each other.

The second step of the experiment was to soak the seeds in water overnight. This action was made to prepare the seeds for germination and making them more softer and less rigid. The seeds were placed in a bowl and were covered by tin foil. It was set up on the refrigerator to minimize any outside interference that may come to it. After a full night of absorbing the water, the seeds were ready to start the next stage.

In this practical, six bags containing twelve histrix cactus seeds each were taken and another six bags containing twelve rocket salad seeds in each bag. Each bag was experimented with different concentrations of gibberellic acid to see how fast each would grow. Gibberellic Acid is an organic

Title: The Effects of Freezing on Germination Rate Introduction: The purpose of this experiment was to discover which species out of three seeds would have the germination rate be the most negatively affected after being frozen for several days. Seed banks store frozen seeds which implied that freezing seeds doesn’t cause any major damage to the seeds. However, some species of seeds would probably be more resistant to being frozen than others. Seeds are native to and are grown in many different types of environments some of which are much warmer and colder than others so there seemed to be a possibility that plants from colder environments would produce seeds less susceptible to damage from low temperatures.

On the first day, four Styrofoam cups were obtained, and with the use of a pencil, holes were punched in the bottom of each of the cups in order to provide the plants with water. Cups were labelled in sequence: rosette-water, rosette-gibberellic acid, wild-type-water, and wild-type-gibberellic acid. Each cup then received approximately one inch of moistened soil. Following the addition of soil, 3 pellets of fertilizers were placed in each of the cups. Then, an additional inch of soil was placed over the pellets in each of the cups. Once the soil was settled, seeds were added to the cups. There were two types of seeds: rosette Brassica rapa seeds and wild-type Brassica rapa seeds.

The experiment commenced with planting over one hundred and thirty Brassica rapa plants. A large abundance was planted to ensure the large diversity of plants, which would also ensure a number of plants would be available to artificially select. Each Brassica rapa was planted with about one hundred and thirty plants to ensure the genetic diversity but this process first commenced by accumulating small plastic pots; it was important that these pots have holes in them so that they could be filled with wick. The small piece of wick would serve as a safety net for the Brassica rapas in case they do not receive water. The wick would temporarily keep the soil moist, so the plants would not immediately face peril. We also kept the soil moist

The next chapter in the unit covers some of the terrestrial organisms, fungi and plants. Plants are autotrophs who make their food from light energy in photosynthesis. There are many varieties of plants including gymnosperms, angiosperms, simple plants like ferns and moss. Reproduction in plants is usually done by the wind or other organisms to disperse their seeds and pollen throughout the

Labels were first made for Intraspecific and Interspecific for each plastic pot measuring 6cm by 6cm by 8.5cm. There was 10 pots filled ¾ of the way full, with Sta-Green™-moisture mixture plus wood fertilizer, for each of the twenty groups. For intraspecific a control was set with one Brassica rapa seed directly in the center of the pot. Then 2 Brassica rapa seeds were placed together equal distances apart into two pots. In another two pots, four Brassica rapa seeds were placed together equally apart. The last two pots had 8 Brassica rapa seeds equally apart. The Brassica rapa seeds used in this experiment are Wisconsin Fast Plant™. For the interspecific groups,the plastic pots were the same as above and each filled ¾ full of the same potting

In this study, hormones were used as GA3 (gibberellin), ABA (abscisic acid), IAA (indole acetic acid), 6-BA (cytokinin), NAA (naphthalene acetic acid). It is difficult to germinate at 25 ℃, but the germination rate is improved under the condition of exogenous IAA. The germination rate of Lambia alone was 20% under 50mg / L-100mg / LIAA treatment. However, with the increase of IAA concentration, the germination rate increased gradually to 40% at 200mg / L, but not 100% Seed dormancy is not completely lifted. But the IAA can indeed be in a certain concentration on the stalk of the seeds of the germination of the promotion of the role. IAA has a certain inhibitory effect on the germination of
