The Influence of Abiotic Factors on the Growth Pattern of Monotropa uniflora By Katherine Dami, Jennifer Ferlenda, Annarose Quinn
Introduction M. uniflora grows in moist conifer or hardwood forests (Kong, 2015). Evolved from an autotrophic ancestor (Hirce, 1972). Do not have chlorophyll (Lutz, 1973). ~4,000 known parasitic plants (Press, 2005) Associates with fungal species in the family Russulaceae (Massicotte, 2004). Spend their life underground without light, except for its flowering period when they develop shoots (Tsukaya, 1998)..
Our Interest Most studies focused on phylogeny...we wanted to do something different (Kong, 2015)
Hypothesis 1 H 1 : As canopy cover increases, Monotropa uniflora will grow in larger clusters. H 0 : Canopy cover has no effect on the growth pattern of Monotropa uniflora.
Hypothesis 2 H 1 : As soil moisture increases, Monotropa uniflora will grow in larger clusters. H 0 : Soil moisture has no effect on the growth pattern of Monotropa uniflora.
Hypothesis 3 H 1 : As ph decreases, Monotropa uniflora will grow in larger clusters. H 0 : Soil ph has no effect on the growth pattern of Monotropa uniflora.
Experimental Design Independent Variables Soil ph Soil temperature Soil moisture Leaf litter thickness Canopy cover Dependent Variable Growth pattern of M. uniflora (single, double, triple, etc.)
Methods Population 2
Soil Moisture Probe (%) Soil Temperature Probe( C)
Spherical Densiometer- Canopy Cover (%) (Pleus & Shuett-Hames, 1998)
Ruler- Height (cm) Calipers-Diameter (mm)

Population 1 Data
Results/ Overview of System
y= -2.949 + 0.4203x p = 0.209 R 2 = 1.6% Stem Number Soil Temperature ( C)
Stem Number y= 3.133 + 0.2096x p = 0.381 R 2 = 0.8% Leaf Litter Thickness (cm)
y= 9.219-1.079x p =0.183 R 2 = 0.8% Stem Number Soil ph
y= 6.558-0.2116x p = 0.016 R 2 = 5.8% Stem Number Soil Moisture (%)
y= -14.49 + 0.2128x p = 0.019 R 2 = 5.6% Stem Number Canopy Cover (%)
Ecological Theory Does it support what is known? Why did we get these results? Self critique Follow up studies Discussion
