Does floral scents and red appearance of Calliandra haematocephala affect its pollinator attraction?

Introduction
Calliandra Haematocephala, a type of tropical plants, has attractive red flowers and floral scents. Due to high density of plants and lack of consistent wind, insects, such as bees, are main pollinators in tropical rainforest. In order to increase rate of reproduction, tropical plants need to have traits that attract their pollinators. According to previous experiments, Campanula has visual and olfactory attraction to Ch. Rapunculi. (Milet-Pinheiro, 2015). Cornus Capitata also provide visual and olfactory cues to its pollinators in order to have more attraction. (Song, 2015). Based on the results of previous experiments, it is …show more content…
By observing from the surveillance cameras, I will record the number of honeybees staying on each group of flowers every two hours. Average number of honeybees will be calculated after the experiments.

Note: The color used to spray will be from same brand and have will have pungent smell.

Prediction
For the experiment in G1, my null hypothesis will be that floral scents of Calliandra Haematocephala do not affect its attraction to honeybees. If my results show that the average number of honeybees staying on different groups of the flowers in G1 are very similar, my null hypothesis will not be rejected. If my results show that there are obvious differences from the average number of honeybees staying on the flowers in each group, my null hypothesis will be rejected.

For the experiment in G2, my null hypothesis will be that the red appearance of Calliandra Haematocephala’s flowers does not affect its attraction to honeybees. My results will not reject this null hypothesis, if the average number of honeybees staying on different groups in flowers are very similar. My results will reject the null hypothesis, if the average number of honeybees staying on the flowers in each group are much different from others.
