Objective:
The experiment aims to investigate how the cut Gerbera could be extended the life by adding a series of solutions, and to account for the underlying reasons for the extension. It also provides insight into the effectiveness of different “flower foods” and the role of bleach in the whole system.

Abstract:
Six Cut flowers (Number. 1, 2, 5, 6, 7, and 8) were placed in different vases from 10th March 2011 to 25th March 2011. Solution 1 and 2 which contained water and water mix bleach can last for at least 8 days. Solution 5 and 6 which contained lemon juice and sugar were tending to last for longer for 10 days or more. Solution 7 and 8 can only last for 4 – 5 days since Coca Cola, bleach and warm water were added.

Introduction:
People always want to keep the flowers for a longer period. In the experiment, different kinds of chemicals were used to show how the solution makes Gerbera, which is a genus of ornamental plants from the sunflower family, to have a longer lifetime. The chemicals used in the experiment include bleach, sugar, lemon juice and Coca Cola. The effectiveness of various solutions to the lifespan of Gerbera would be discussed.

Procedure:
Six Gerberas were used and each of the flower stems was cut at an angle of 45 degree. Also, six plastic bottles were collected and used as vases, and six different solutions were separately poured into each of the containers. Each flower had a stem of 40cm and 30cm of which was immersed in the water. For solution 1, 1 liter of tap water was added in the container. For solution 2, 1 liter of tap water and 1/2 teaspoon of bleach were added in the bottle. For solution 5, 1 liter of tap water and 2 table spoons of fresh lemon juice were poured into the containers. For solution 6, 1 liter of tap water, 2 table spoons of fresh lemon juice, 1 table spoon of sugar and 1/2 teaspoon of bleach were added into the vase. For solution 7, 1 can of Coca Cola which was degassed by warming and 2 cans of tap water were added in the bottle. For solution 8, 1 can of Coca Cola which was degassed by warming, 2 cans of warm water and 1/2 teaspoon of bleach were added in the vase. Six containers with flowers were put in a place where kept out from direct exposure of sunlight until they wilted. The solutions were changed every four days of the same composition. The daily temperature, the flowers and the condition of the solutions were recorded every day; photos were also taken for every day to mark the changes of the flowers and the condition of the solutions.

B = Bloomed
F = Petals fell off
W = Wilted

Solution 7 was the first solution wilted, that was on 17/3 and solution 8 wilted 1 day after the former and was the second solution to wither; whereas solution 2 died on 21/3.
Both solution 1 and 6 withered on the same day on 23/3, and on 25/3, solution 5 was the last one to wilt....
