The original hypothesis, “If ascorbic acid has positive effects on radish seed germination, then radish seeds germinated with ascorbic acid concentrations of 0, 100, 300, and 500 parts per million (ppm) solutions will exhibit longer seed radicles (measured in millimeters) than control seeds germinated in distilled water alone” was incompletely supported. For example, Graph 1 shows the Control trial achieved the greatest average length (31.5 mm) by the end of the experiment in comparison to all…

The Quaking aspen (Populus tremuloides) is a very abundant tree in the mountainous regions here in Utah. Moreover, this particular species of tree is very popular because it grows most commonly around burn sites. After a natural disaster the Quaking aspen is usually one of the first trees to take root. The Quaking aspen is well known here because of this, however the common person may find it hard to identify when an aspen tree is not healthy. Sooty bark canker (encoelia pruinosa) is a canker is…

Data Analysis: Microwave Radiation and Plant Growth How does radiation affect the growth of plants? If seeds are exposed to microwave radiation then the growth process will increase. Get three seeds of the same type of vegetable (cucumbers were used in this experiment). Before planting, microwave plant cell #2 for 15 seconds and plant cell #3 for 30 seconds (plant cell #1 is not microwaved at all). After planting them, see the difference in the growth of these seeds over 35 days. The…

thick white sap from any cut or broken surface. This sap contains a poison called Cardiac Glycoside. Many insects rely on milkweed for a food source, specifically the monarch butterfly depends on milkweed with the larvae eating the leaves of the plant. Interestingly the monarch caterpillar eats the leaves and absorbs the glycosides within its body and…

In order to exam the effects of auxin, gibberellins and abscisic acid on plant growth we generated an experiment to track the growth, specifically height of a corn seed. To begin, obtain two small planters, each with six individual compartments. Label one planter A and the other B. On the outside of the two small planters label five of the six compartments IAA, NAA, GA, ABA, and Control. The sixth compartment will not be used. These labels respectively correspond to the hormone treatment that…

I measured a tall tree in my front yard three different ways using indirect measurement. I used shadows to create separate similar triangles (method 1), a mirror and my own height to create similar triangles (method 2), and shadows to create inset triangles (method 3). I also used a tangent, secant, and the Pythagorean Theorem to find the radius of a circular flower garden in my yard (method 6). For method 1, I found that the measurement of me to the end of my shadow from the tip of the tree’s…

Differences in spectral, spatial, radioactive and temporal characteristics could provide various sources of imagery. A vegetation classification developed from the characteristics is important for classifying and mapping vegetation cover. Geographically, Takalar Regency is located at latitude of -5.4162 and longitude of 119.4876. It was the west part from city Makassar in South Sulawesi, Indonesia. It was also close to a boundary of Jeneponto regency. In this study area, it was near with five…

Arabidopsis thaliana Development Introduction Proper plant development is dependent on nutrient availability (Krouk et al. 2011). In this regard, plants can respond to nutrient availability by changing their root system architecture. In particular, phosphate (NaH2PO4) levels were found to affect the root system architecture in Arabidopsis thaliana (Williamson et al. 2001), which might impact overall plant development. A better understanding of plant nutrient requirements is important for the…

PLANT PROPAGATION Plant propagation is the method of producing new plant from a collection of sources like seeds, bulbs, cuttings, layering, other plant parts, etc. Plant propagation is divided into many types:  Sexual propagation.  Asexual propagation.  Seed propagation mat.  Heated propagator. Now here, we have to discuss about Asexual Propagation. ASEXUAL PROPAGATION : Asexual propagation is a type of plant propagation in which new plant is germinated by artificial means of method without…

Beautiful Leaves and Even More Beautiful Bark Amber Jubilee is a relative newcomer in the ninebark (Physocarpus opulifolius) family. Are you familiar with the ninebark family? If not, let Nature Hills introduce you to this great group of shrubs. Few shrubs are easier to grow than Ninebark. This North American native can handle just about anything you can throw at it. Unless you’re planting in beach sand, it will grow in your soil. It can handle droughts and torrential rains, even wet feet by…
