Plant material Seeds of Artemisia vulgaris L. were surface disinfected with 10% (v/v) dettol solution (Reckitt Benckiser, Kolkata, India) for 5 min, followed by rinsing three to five times in sterile distilled water. The seeds were then surface sterilized with 0.1% (w/v) aqueous mercuric chloride (HgCl2) for 4-5 min and finally rinsed with autoclaved distilled water (three to five changes). Surface sterilized seeds were inoculated into culture flasks containing 25 ml MS medium supplemented with 10% (v/v) filter sterilized coconut water and incubated in a dark chamber for 5-7 days at a temperature of 23C to facilitate germination. Later they were transferred to photoperiodic conditions and maintained for another 28-32 days for seedling growth. …show more content…
vulgaris. Both the basal media were supplemented with 3% (w/v) sucrose and were solidified with 0.7% (w/v) agar and different concentrations of cytokinins including 0.44-13.32 M BA (benzyladenine), 0.46-13.92 M KN (kinetin) or 0.49-14.76 M 2iP (2-ispopentenyladenine).
2.4. Effect of carbon sources Shoot tip segments were cultured on MS basal medium supplemented with 4.92 M 2iP and different types of carbon sources, including 3% (w/v) of glucose, fructose and sucrose.
2.5. Effect of cytokinins Shoot tip segments were cultured on MS medium containing 3% (w/v) sucrose, 0.7% (w/v) agar and supplemented with different concentrations and combinations of cytokinins including 4.92 M 2iP + 0.444-13.32 M BA; 4.92 M 2iP + 0.464-13.92 M KN; 2.22 M BA + (0.464-13.92 M) KN + 4.92 M 2iP.
2.6. Effect of amino acids Shoot tip segments were excised and cultured on MS medium containing 30 g l-1 sucrose, 7.0 g l-1 agar supplemented with 4.92 M 2iP and 2.22 M BA and different concentrations of amino acids (glycine, Asparagine and proline ) (0.5 – 3.0 mg/l) individually and examined for improvement of shoot multiplication. The shoot sprouting frequency (%), number of shoots per explant and shoot length (cm) were recorded after 30 days of culture.

Ten to twenty explants were used per treatment in each replication. Observations were recorded on the frequency (number of cultures responding for multiple shoot proliferation and root development) and the number of shoots per explant, shoot length, number of roots per shoot, root length, increase in plant height after successive hardening, number of inflorescence heads per plant, number of floral buds per inflorescence respectively. The analysis of variance (ANOVA) appropriate for the design was carried out to detect the significance of differences among the treatment means and the treatment means were compared using Duncan’s Multiple Range Test (DMRT) at a 5% probability level (Gomez and Gomez,
In addition, the average height of the seed, with pure water, after 8 days, was 8.9 centimeters whereas the average height of the seeds with 4% of “Miracle Gro” was 0.3 centimeters. The difference there is a whopping 8.6 centimeters. Not only that, but the seeds have a coating and when it separates from the seed that signals that the seed is beginning to germinate. After the 8 days, the seeds with only water were all separated from their covering, while the 4% solution only had 2 beginning to peel. Finally, we concluded that because of osmosis, the seeds with more “Miracle Gro” were bound to grow the least.
rapa our class planted Brassica Rapa seeds at high densities and low densities, the low density, with two seeds, and a high density with ten seeds into pots that were 400 mL. We added a conservative amount of water by sprinkling it, as well as fertilizer and then placed the pots on a rack under 40 watt lights. After 5 weeks, we harvested the plants and measured height and survivorship. We compared the height and survivorship between the high and low densities using an unpaired T-test in JMP. Results
Cherry Angioma A cherry angioma is a common skin growth that can appear on any area of your body. It is also known as a senile angioma or a Campbell de Morgan spot, a common kind of benign (not cancerous) skin growth. It is common in people ages 30 and above. Angiomas result from abnormal growth of small blood vessels, which may get broken, giving the cherry angioma
On day one no seeds germinated. By day two, seeds in the control group, 15% and 25% experimental groups had germinated. On day two the experimental group with 25% concentration of miracle gro’ had the most seeds
Dermatomyositis is an uncommon inflammatory muscular disease, which involves the degeneration of collagen, discoloration and swelling of the skin and underlying muscle. Dermatomyositis is known by it’s distinctive skin rash and muscle weakness. Dermatomyositis affects children and adults, but it usually affects children between the ages of five and fifteen, and it occurs in adults in their late forties through sixties. Dermatomyositis is also more commonly found in females than males.
These complex organisms consist of two organ systems, the root system and the shoot system. The shoot system is an above ground organelle system, this is where the leaves, stems, buds, flowers (depending on the plant) and fruits (depending on the plant) are found. Thus, therefore, meaning that the root system is the below ground system and includes the roots, rhizomes and tubers. There are three types of plant cells which are formed in the meristem (tissue in most plants that contain undifferentiated cells, the cells produced here help various organs of the plant and help with the growth of the plant.) The first plant tissue grouping is Dermal, the Dermal system looks after the covering of the plant, and can be broken down into many subsystems.
Have you ever held an infant before? You know, like a young, innocent, precious human being just lying there in your arms; feeling yourself become stiff because you’re afraid that you might scare it or make it cry or just hurt it? Knowing that the life this small, defenseless, piece of breathing flesh is in your hands? Imagine it instead of one baby, hundreds of them, maybe thousands; and not just babies but kids, teenagers, elderly, men and women in general. The fact that more than a thousand people, risking their lives and everything that they have, are all on your hands.
Only one of these seeds sprouted with the rest of them being over watered. If the experiment was to take place again, the measurement increments would probably have been 2.5 mL, 5 mL, 7.5 mL and 10mL. Suggest any improvements to the experiment to reduce any
In images C and D, a clear circular ring was produced after the first day of incubation. This was a mean of the plant fighting the bacterium, almost like the plant produced a barrier against the bacterium. The agar plates remained the same until the experiment was completed after 4 days. Therefore, one can concluded that the
However, after investigation through gel electrophoresis, the three kinds of plants were not identical. This relates to the
Applying the idea of learning in plant systems certainly makes for fascinating future ideas and research. The mimosa pudica in itself is enough to stimulate new testing with its unique capabilities and
The B. Vulgaris samples were approximately 1cm3. They were kept the same size to ensure accurate results. A control test was conducted in distilled water to obtain a result to compare. The ethanol treatments were 40% and 70%. To prepare the solutions a 70% ethanol solution was used to make 40%.
This root tip was choosen because of its rapid growth and it can be easily avaliable and grown in large numbers. The rapid root growth proved advantageous as it allowed the observation of multiple cells in each mitotic stage within a small sample. It was expected that the majority of the cells found would be in interphase as a large proportion of the cell division cycle is spent with the cell performing its normal cellular functions. Materials: The Materials required for this experiment include; a
Instead, it provides turgor pressure from inside the cell that prevents the plant from wilting. If plant cells are places in isotonic solutions they begin to lose their shape and color. If they are placed in hypertonic solutions the cytoplasm shrinks within the cell, similar to that of the animal cell. However, the rigid cell wall remains intact, which is referred to as plasmolysis. With these observations and explanations in mind, I ultimately concluded that plant cells prefer solutions with low solute concentrations and high osmotic potential, hypotonic, while animal cells prefer solutions with identical solute concentrations and osmotic potentials,
The leaves on the plant are stable and thick, and the plant stays in the upright position during the duration of the lab (Fig. 3). The dirt and water plant starts to grow a new plant in the pot on day 15 (Fig. 4). The soil and water plant is the healthiest of the five and this observation does not agree
