Is There A Correlation Between Water Potential And Mechanical Strength Of Stems Of Malosma Laurina?, William Chang, Lauren Price, Nicolas Pak
Is There A Correlation Between Water Potential And Mechanical Strength Of Stems Of Malosma Laurina?, William Chang, Lauren Price, Nicolas Pak
Featured Research
The purpose of this experiment was to see if there was a correlation between water potential and the stem mechanical strength of the Malosma laurina. This experiment was conducted with the use of a Scholander-Hammel pressure chamber to find water potential and the Instron 5500 to test the mechanical strength of the stems. After analysis of the data, there was no direct correlation between water potential and the mechanical strength of stems of Malosma laurina.

Photosynthesis is the process by which plants convert light energy to chemical energy, helping sustain life in the biosphere. There are many factors that affect the rate of photosynthesis such as atmospheric CO2 concentration, temperature, and sunlight. In this experiment, we attempt to determine what effect, if any, the mechanical strength of a plant has on its rate of photosynthesis. To perform this experiment we used both the LI-COR 6400 and the Instron Mechanical Testing Device. With the LI-COR we measured photosynthetic rate of our plant subjects in real time during the prime photosynthetic hours, 10-12am. The Instron allowed us …

The Santa Monica Mountains ecosystem has a high diversity of plants with different lifestyles that produce different physiological characteristics individual to all plants. Studies in Australia, another Mediterranean ecosystem, have shown that mechanical strength of leaves is relatable to soil stress. This experiment seeks to determine whether mechanical strengths of leaves correlate to stomatal conductance of leaves across different species in the Santa Monica Mountains. Four species of plants are tested for their stomatal conductance in the field, and the leaves are tested for tensile strength using Young’s Modulus for comparison across leaves. These data show that there was no …
