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