Factors Of Seed Germination Of Raphanus And Cucumber

Germination is the stage of plant growth through which a seed becomes a seedling plant. First, the seed begins to absorb water and the radicle root emerges from the seed coat and into the water. Then, the primary roots grow, the cotyledons move above ground, the stem begins to grow, and leaves develop. The process is complete when the first leaves open and the cotyledons fall off (The Learning Garden 2001).

When planting a seed, many factors allow the seed to grow and become a plant. To sprout from the ground, and to survive, seeds need water, air, and a certain temperature. Seeds can get water, oxygen, and sun by being placed at the proper planting depth. Planting depth is the depth at which a seed is placed in the soil. If a seed is exposed to these important needs, it goes through a process called germination. According to the Wise Geek article, “What is Germination?”, “Germination is a process in which a seed or spore awakens from dormancy and starts to sprout.” (“What is Germination?”).

There are many ways to obtain seeds to grow flowers in the springtime, but not all seeds were created equal. Sunflower seeds, for example, can be bought at a garden store in a packet for $1.5 dollars per 6 gram packet, but they can also be found in bird seed for $3.53 dollars per 10 pounds. This experiment intends to find if the germination of a store bought packet of sunflower seeds matches the germination rate of sunflower seeds obtained from a bag of bird seed. While both seeds will germinate, it is believed that the bird seed will not be as robust in growth as the garden seed, due to the fact that the garden seed is made to be grown, while the bird seed is made for consumption.

This experiment was performed to give a better idea of interspecific competition and intraspecific competition between radish seeds and wheat seeds at high and low densities. By planting two species only pots and two combined species pots our results showed that the radish seeds performed better at both interspecific and intraspecific competitions and concluded that the lower the pot density the more resources and growth. 32 radish seeds were evenly planted in pot A1 followed by 32 wheat seeds planted in pot A2 and 16 of each radish and wheat seeds combined (32 total) planted in pot AB1. We repeated this procedure again but this time planting 96 radish seeds evenly in pot A2, 96 wheat seeds in pot B2 and 48 of each radish and wheat seeds combined (96

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

Weeds assume control over a garden by spreading their seeds around. Pre-developing weed executioner works by ensuring that the seeds of yard weeds absolutely never grow. As the weed seeds lie in your dirt through the winter months sitting tight for the temperature to be correct

Gibberellin Acid is a plant hormone that can affect plant growth by manipulating the cell division, stem elongation, and even mobilizes food resources within the endosperm to increase seed germination (Wiathrop, 1998). This experiment took place to test the factor of whether or not gibberellin could allow a seed to germinate and grow in the absence of light. Plants were distributed five drops of gibberellin and then placed in the cabinet for a total of three weeks. Each week, we recorded the growth of each plant. As a result of the three weeks, only one of the two hormone-induced plants successfully sprouted to a total of 16.2 centimeters. The other hormone-induced seed showed germination however, resulted to zero vertical growth,

A piece of filter paper was moistened and then placed in a petri dish, and any excess water was poured off. The harvested seeds were then placed in neat rows on the upper two-thirds of the filter paper. The petri dish was then tilted on end in a water reservoir containing approximately two centimeters of water. The reservoir and dish were then placed under the fluorescent light to germinate for 48 hours. After the 48 hours, the

Comparing the times evaluated in the ultrasonic bath (2 and 4 minutes), according to the statistical analysis there is no significant difference between the different times, because they present results very close to the percentage of germination of the seeds. Of the seeds that remained for 2 minutes in the ultrasound bath, 65% of them germinated, and of those that remained for 4 minutes in the ultrasound bath, 68% of them germinated. However, the statistical analysis showed that there is a significant difference between seeds that have undergone ultrasonic treatment and seeds that have not undergone any type of treatment, proving the need for a treatment to break dormancy of the seeds of this species, since of the seeds that have not undergone

Germination of a seed is the process Germination is the process when a plant grows from a seed. The seed stores the embryo until the conditions for germination are met. When the seed is placed in sustainable environmental conditions its embryo will grow and burst through its coating. The seed coat protects the seed before germination begins. This is important when the seed is in dormancy- the state of the seed being prevented from starting the germination process due to environmental conditions that may affect the chances of the seed growing. Germination takes

The purpose of the experiment determine whether a plant watered with diluted aspirin will grow faster than a plant watered with normal water. We seeking to answer the scientific question, “Does aspirin improve the growth of plants?” Our hypothesis is the more aspirin a plant is given the faster and higher the plant will grow. We compared the results of three groups of lima beans. The first group received normal water while the second the third groups had aspirin added (second group had one aspirin and third group had two aspirins). We used two plants for each group so if one died the experiment could continue. Our experiment demonstrated the addition of aspirin has a positive impact on plant growth with the third group (two aspirin added)

Purpose: To see the effect of an acid introduced during seed germination, on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better, and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the salt builds up and can contaminate the soil. Knowing the effects of salt on seed germination will allow us to know for sure if the salt is affecting the plants growth or not.

Chamomile and yarrow are both medicinal plants cultivated all over the world in an effort to determine the main active compounds from plant materials. The main factors that influence plant growth and development are temperature, light, and plant date. An extensive amount of studies have been done on the effect of controlled conditions on the growth of in vitro and in vivo chamomile and yarrow cultures (Giorgi et al., 2014; Mohammad et al., 2010).

The nematicidal effect of aqueous extracts of plant viz., P. hysterophorus, C. citrates, E. crassipes, M. deliciosa and T. cardifolia showed in Table (3) against the juvenile penetration in the roots of brinjal seedlings. The minimum penetration of second stage juvenile of M. incognita observed by P. hysterophorus 38, 33, 29 followed by C. citrates 43, 40, 36, E. crassipes 46, 43, 38 and M. deliciosa 49, 47, 42 after 3 days at the doses of 5g, 10g and 15g. While maximum penetration of second stage juvenile showed by T. cardifolia 53, 49, 44 at the same dose. Higher doses of all five plants viz., P. hysterophorus, C. citratus, E. crassipes, M. deliciosa and T. cardifolia were preventing the penetration of second stage juvenile in the roots
