  • 3. INTRODUCTION
    • Strawerries are the most popular summer fruits.
    • They are a healthy product :
    • Vitamin C
    • Minerals
  • 4. OBJETIVES
    • The main purpose of this study was to compare how cultivation, variety fertilization, region, weather conditions and ripeness degree could affect the nutritive values of strawberries.
    • The variety used for the study:
    • “ senga sengana” and they are
    • compared to five other
    • alternatives.
  • 5. METHODS
    • They were collected between 1997 and 1998
    • The berries were cultivated in similar growing conditions
    • The samples were 1000 grams and they were separated in different subsamples.
    • The parameters to analyze were:
    • Mineral elements
    • Vitamin C
    • Pesticides
  • 6. MINERAL ELEMENTS
    • The conclusions were:
    • Potassium was the main mineral followed by Calcium and Magnesium.
    • Most of the minerals in the strawberries have a well-regulated homeostasis.
    RESULTS
  • 7. VITAMIN C
    • Content of Vitamin C in strawberries is not affected by organic cultivation.
    • Significant differences were found statistically among the varieties in both years .
    PESTICIDES
    • No illegal use was detected .
    • The concentration of pestice was lower than the highest accepted level .
    RESULTS
  • 8. CONCLUSION
    • The genotype and the origin have a more important effect on the fruit than the techniques used for its cultivation.
    • All strawberries were safe for their consumition.
    • Every agricultural practice analyzed was developed correctly.
    • There are some differences among the varieties of strawberry studied
  • 9. PERSONAL CONCLUSION
    • We think:
    • * that this experiment is an important study because it displays the differences among several varieties of strawberries.
    • We suggest:
    • * Strawberries in all diets because it is a quite complete fruit
