Radishes And Collard Lab Report
Survival and Leaf Growth of Radishes and Collards in Intraspecific and Interspecific Settings
Abstract
The purpose of the experiment was to observe how density and competition among individuals of the same species and of different species affects the growth of leaves and survival of collards and radishes. The experiment was carried out in the Greenhouse at the University of South Carolina, and utilized set up with six groups with four pots per group. The pots consisted of low density radishes, low density collards, high density radishes, high density collards, low density radishes and collards together (mixed-species pots), and high density radishes and collards together. After six weeks of growing, biometrics were taken, and specifically …show more content…
Graph 1: The average leaf weight of the radishes can be seen to be much higher in the high density setting, not supporting the hypothesis.
The collard leaf weight was also recorded (grams), and another single factor ANOVA analysis was performed to provide more information. The P-value in this analysis was 0.903093, again much higher than the α-level. Table 2 summarizes the analysis of the collard leaf weight in high and low densities. Graph 2 also displays visually, the difference in the average leaf weight of the collards. Although the average leaf weight is ever so slightly higher in the low density setting, it is not significantly higher (0.04462 grams in low density as compared to 0.04346 grams in high density).

Graph 5: the survival of the collards in the low density setting can be seen at about 3x greater success than the high density setting for intraspecific competition.
Lastly, another two factor ANOVA analysis was performed in terms of the success (survival) of the plants in the interspecific setting. Table 6 displays the species P-value generated by the ANOVA was 0.021921, indicating there is a significant difference in the survival of radishes and collards in the interspecific setting. The density P-value, 1, is extremely large and shows there is no difference whether or not the plants are in a high density or low density area when in mixed-species pots. Finally, the interaction P-value was also higher than the α-level of 0.05, at 0.679457, again indication there is no relationship between the low and high densities versus the plants species. Graph 6 displays the survival of the mixed-species setting at both the low and high density settings.
