The Effects Of Leaf Hydration On Light Reflectance In Salvia Leucophylla And S. Mellifera, Logan A. Schmitz, Kolina Mah-Ginn, Hayley Presthus
Featured Research
The presence of trichomes on a plant affect the plant’s ability to retain water; this, in turn, must affect light propagation and reflectance. It was hypothesized that a plant with a higher trichome density (Salvia leucophylla) would have a greater change in reflectance when exposed to a more aired or hydrated environment than a species with a lower trichome density (S. mellifera). Results obtained using a Unispec suggest that Salvia mellifera is more resistant to change in NDVI in response to drying and wetting. Water potential data suggest this may be related to the plant’s resistance to actual drying and …

The Effect Of Leaf Trichome Density On Stem Mechanical Strength In Salvia Leucophylla, S. Mellifera, And S. Apiana, Brieanna English, Jeff Scanlon, Anushree Mahajan
Featured Research
Salvia species in southern California exhibit a variety of leaf trichome densiIes. S. mellifera, S. leucophylla, and S. apiana were chosen as study organisms because they exhibit varying trichome densiIes. A UniSpec was used to measure NDVI in leaves and an Instron was used to measure stem mechanical strength. This study provides preliminary evidence that suggests plants with high leaf trichome density have less stem mechanical strength, and those with low leaf trichome density have greater mechanical strength. Data generated from this study supports the idea that this may be a general and loose trend amongst plant families similar to …
