INTRODUCTION Strawerries are the most popular summer fruits. They are a healthy product : Vitamin C Minerals

Strawerries are the most popular summer fruits.

They are a healthy product :

Vitamin C

Minerals

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.

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.

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

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

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

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.

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

Content of Vitamin C in strawberries is not affected by organic cultivation.

Significant differences were found statistically among the varieties in both years .

No illegal use was detected .

The concentration of pestice was lower than the highest accepted level .

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

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

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
