Many sailors used to get scurvy because they had no fresh fruits and vegetables on board the ship. .

EVALUATION.
The results obtained were fairly conclusive; however, the following limitations have to be taken into consideration.
Vitamin C decreases with temperature. High nitrogen fertiliser rates can lower vitamin C levels in citrus fruits. Proper potassium levels are also needed for good vitamin C levels. Additionally, climate, especially temperature and total available heat; affect vitamin C levels. Areas with cool nights produce citrus fruits with higher vitamin C levels. Hot tropical areas produce fruit with lower levels of vitamin C. Environmental conditions that increase the acidity of citrus fruits also increase vitamin C levels.
This vitamin decreases during the ripening process, therefore the freshness of the fruit has to be considered. Immature fruit has the highest levels. The position on the tree also affects vitamin C levels. Since sunlight exposure enhances vitamin C levels, fruit positioned on the outside of the tree and on the south side have higher levels.
