1.1 Investigative question
How will the use of pesticides and the presence of aphids affect the growth of iceberg rose bushes?
1.2 Background information
In South Africa, Iceberg Roses are not only known to bloom all year round but they are also known to attract aphids. This not only causes for the flowers of the plants to look unappealing but they can also affect the growth of the plant. However, the problem that many rose bush owners have is that they do not know if growing a plant with the use of pesticides will be of benefit or if it will also degrade the flowers’ quality and the growth rate of the plant.
The iceberg is a white floribunda rose cultivator group bred in Germany in 1958. The plant has gone under the marketing …show more content…
This will be determined by inspecting its general health by looking at the state on the leaves, the state of the flowers and the colour of the petals. The quantitative data that will be collected will be that of the height of the plants as well as the size of the number of aphids, predators and …show more content…
The independent variables of the experiment will be the placing of the plants, whether they are in the enclosure or not, and the pesticides allocations, meaning that only the plants in the enclosure will be sprayed while the others are not. The controlled variables are the type of plants, the size of the flower pots, the amount of time for the plants to be left outside, the type of soil, the general age of the plants and the amount of water each plant receives.
1.4 Aim
The aim of the investigation is to establish the better option of growing techniques used when planting roses. The techniques being having the use of pesticides present whilst the plants are in an enclosure or not have the presence of pesticides as well as the plants not being put in an enclosure.
1.5 Hypothesis
If the rose bushes are placed within a secure enclosed area, then the pesticides will cause the plants to grow at a higher quality, size and state of health than those outside of the
