Catalonia’s Geography, Climate, Resources, and Cultural Heritage

1. Territory and Natural Resources

1.1 Territorial Configuration

Catalonia, characterized by a 552km Mediterranean coastline and a complex 31,130 sq km terrain, presents a diverse landscape. From coastal plains to mountainous regions with altitudes exceeding 5% above sea level, the territory features a mix of plains, plateaus, cliffs, depressions, hills, and old alpine massifs. The proximity of mountains and sea creates a rugged coastline, leaving narrow coastal plains. The sea plays a crucial role

Andalusian & Catalan Coasts: A Geomorphological Study

Andalusian Atlantic Coast

The Andalusian Atlantic coast stretches from the Portuguese border to the Rock of Gibraltar and the Bay of Cádiz. Alluvial deposits from rivers have created low-lying coastal plains with small sand dunes, similar to those found along the coasts of Huelva and Cádiz. Ocean currents accumulate sand in places, forming littoral arrows (coastal formations built up from accumulated material resting on a rocky coast or island).

If these sandy formations run parallel to the coast,

Seed Maturity & Propagation Techniques: Lab Methods & Field Practices

Determining Seed Maturity: Lab Methods

1. Dry Weight

Maximum dry weight indicates maturity.

2. Moisture Content

Some fruits lose moisture during maturation.

3. Analysis and X-ray Method

Chemical analysis and X-ray imaging can assess maturity.

Determining Seed Maturity: Field Methods

1. Fruit Weight

Fruit weight generally decreases with maturity.

2. Seed Contents

Mature seeds have a firm, white endosperm and a well-developed embryo.

3. Fruit Color and Odor

Slight variations in color and odor can indicate maturity.
