Title: The effect of ethylene production on the unripe banana when are stored together with pear in a bag.
Hypothesis: Ethylene is a plant hormone released as a gaseous state into the air by rapidly growing tissues and it affects the surrounding fruits. Iodine solutions bind to the starch of the plant by forming a dark complex. So the darker the fruit, the lesser the content of starch which means the fruit is unripe and vice versa. The lighter color of fruit represents a more ripening status of fruit.
Variables.
Independent variable: Concentration of ethylene
Dependent variable: Conversion of starch into sugar (ripening of fruit).
Control (describe at least 2):
- A total of 8 bags will be made, Bags 1-4 will be the control group and 5-8 will be the test group.
- Put 1 unripe pear in each of the control bags. Seal each bag and one unripe pear and 1 banana in each of the test bags and seal them.
- Place all the bags together and record the observations from the initial appearance to the final appearance of the fruit each day.
- after few days the ripening status of them is tested by staining them with the iodine solution.
Method:
- After preparing the iodine solution, pour the iodine stain into a shallow tray and dip it with a half-cut pear.
- Allow the fruit to absorb the stain and remove and rinse it with water.
- Repeat the step by adding more stain as needed to observe the ripening status.
