Cómo cultivar fresas a partir de semillas 0 - 1

<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> </head> <body> Strawberries are hardy perennials, but the plants become less robust after about three years. Start your strawberries from seed, and then propagate by cuttings and runners. Follow along with this handy How to Grow Strawberries from Seeds guide and grow some sweetness.! Latin Fragaria vesca Family: Rosaceae Difficulty Challenging Season & Zone Exposure: Full sun Zone: 5-9 Timing Sow indoors in the winter. An earlier start may result in berries the first year. Start any time between December and the beginning of February. After that time, they will still work, but you will not harvest berries during the first season. Transplant out at least 3 weeks after last frost. Starting Germination is the trickiest aspect to growing strawberries. Be patient, and try the tricks below. Tuck your strawberry seed packet inside a sealed plastic bag or airtight container and place in your freezer for 3-4 weeks. When you remove the bag or container, do not break the seal until it (and its living contents) have reached room temperature. This may take several hours. Err on the side of caution. Opening the package too quickly may result in water condensing on the cold seeds, and this will reduce your chances of success. Once the sealed package has “thawed” to room temperature, you’re ready to plant. Sow the seeds on the surface of pre-moistened, sterilized seed starting mix in trays or small containers. Place these on a piece of felt or other thick cloth that has its end sitting in water. The idea is to wick up water from below so that the seedling medium stays constantly and evenly damp until germination. Keep your seeded trays under bright fluorescent lights at a constant temperature of 18-24°C (65-75°F). Germination may take anywhere from 7 days to 6 weeks. Be patient. Once germination occurs, increase ventilation around your plants to prevent damping off. Once your seedlings have their third true leaf, they can be transplanted into their own pots. Be sure to harden your seedlings off carefully and gradually before transplanting outside. Growing Space transplants 60cm (24″) apart in rows 90-120cm (36-48″) apart. Everbearing varieties (such as ours) tend to produce fewer runners, and will produce more fruit if the runners are removed. In the first year of growth, it may be preferable to encourage runners, and let them fill in the spaces between transplants with new offspring plants. Grow strawberries in a well-drained, sandy loam that has been generously dug with organic matter such as finished compost or well-rotted manure. Dig ¼ cup complete organic fertilizer into the soil beneath each transplant. Keep soil moist, but not soggy. A mulch of straw around plants may help prevent the soil from drying out. Companion Planting These little plants respond strongly to nearby plants. Couple them with beans, borage, garlic, lettuce, onions, peas, spinach, and thyme. Avoid Brassicas and fennel. </body> </html>

Escala de Scoville

0,00 € SKU:

Seeds Gallery Com,

5/ 5

La escala Scoville es una medida del picor o pungencia en los pimientos (también conocidos como guindillas, chiles o ajíes). Estos frutos de plantas del género Capsicumcontienen capsaicina, componente químico que estimula el receptor térmico en la piel, especialmente las membranas mucosas. El número de unidades Scoville (SHU, del inglés Scoville Heat Units) indica la cantidad presente de capsaicina. Muchas salsas picantes usan la escala Scoville para publicitarse en los centros comerciales. <h2>Procedimiento</h2> <div class="thumb tright"> <div class="thumbinner"><img alt="" src="https://upload.wikimedia.org/wikipedia/commons/thumb/7/76/Habanero.jpg/250px-Habanero.jpg" width="250" height="167" class="thumbimage" /><div class="thumbcaption"> <div class="magnify"></div> El chile habanero, uno de los pimientos más picantes, perteneciente al género Capsicum. Muchos habaneros oscilan entre las 200.000–300.000 SHU. La variedad Red Savinas puede llegar a las 580.000 SHU.</div> </div> </div> Esta escala fue nombrada por Wilbur Scoville, quien desarrolló el Examen Organoléptico Scoville en 1912. Éste consiste en una solución con extracto del chile, que es diluida en agua azucarada hasta que el picante ya no puede ser detectado por un comité de examinadores, habitualmente cinco; el grado de disolución del extracto da su medida en la escala. Así, un chile dulce, que no contiene capsaicina, tiene cero en la escala de Scoville. Sin embargo, entre los chiles más picantes, como el chile habanero, se observa un grado de 300.000 o más. Esto indica que el extracto fue diluido 300.000 veces antes de que la capsaicina fuese indetectable. La gran debilidad de este método recae en su imprecisión, pues la prueba está sujeta a la subjetividad humana. Hoy en día ya no se utiliza la medida organoléptica, sino métodos de análisis cuantitativo. Uno de los más habituales es la cromatografía. No obstante, se ha mantenido el nombre de la unidad de medida en honor de Scoville. <h2>Escala</h2> El grado de picor de cualquier pimiento, tal y como se muestran en la escala en "unidades Scoville", es impreciso, debido a que las propias especies tienen variaciones —que pueden cambiar en un factor de 10 o incluso más— en función del cultivo, del clima o incluso del terreno de cultivo (esto es especialmente cierto en el caso de los habaneros).1 Las imprecisiones descritas en los métodos de medida contribuyen a la inexactitud de los valores. Cuando se interpreta un cociente de la escala se debe tener esto en mente.2 <table class="wikitable" style="height:525px;"><caption>Tabla de Scoville</caption> <tbody><tr style="height:36px;"><th style="height:36px;width:136px;">Unidades Scoville</th> <th style="height:36px;width:613px;">Tipo de chile</th> </tr><tr style="height:18px;"><td align="right" style="height:18px;width:136px;">16,000,000</td> <td style="height:18px;width:613px;">Capsaicina</td> </tr><tr style="height:36px;"><td align="right" style="height:36px;width:136px;">2,800,000-3,000,000</td> <td style="height:36px;width:613px;">Pepper X3</td> </tr><tr style="height:36px;"><td align="right" style="height:36px;width:136px;">1,900,500-2,480,000</td> <td style="height:36px;width:613px;">Dragon's Breath</td> </tr><tr style="height:36px;"><td align="right" style="height:36px;width:136px;">1,569,300-2,220,000</td> <td style="height:36px;width:613px;">Carolina Reaper</td> </tr><tr style="height:36px;"><td align="right" style="height:36px;width:136px;">1,300,000–2,000,000</td> <td style="height:36px;width:613px;">Naga Viper, Trinidad Scorpion Butch T</td> </tr><tr style="height:36px;"><td align="right" style="height:36px;width:136px;">855,000–1,041,427</td> <td style="height:36px;width:613px;">Naga Jolokia, 7 Pod Chaguanas45</td> </tr><tr style="height:21px;"><td align="right" style="height:21px;width:136px;">350,000–580,000</td> <td style="height:21px;width:613px;">Habanero Savinas Roja67</td> </tr><tr style="height:21px;"><td align="right" style="height:21px;width:136px;">100,000–350,000</td> <td style="height:21px;width:613px;">Ají habanero,8 Scotch Bonnet, Merkén,8 Chile datil, Capsicum chinense</td> </tr><tr style="height:21px;"><td align="right" style="height:21px;width:136px;">100,000–200,000</td> <td style="height:21px;width:613px;">Rocoto o manzano,9 chile jamaicano picante, piri piri</td> </tr><tr style="height:18px;"><td align="right" style="height:18px;width:136px;">50,000–100,000</td> <td style="height:18px;width:613px;">Chile thai, chile malagueta, chile chiltepín, chile piquín</td> </tr><tr style="height:42px;"><td align="right" style="height:42px;width:136px;">30,000–50,000</td> <td style="height:42px;width:613px;">Pimienta roja o de cayena, ají amarillo,8 chile tabasco, calabrese, algunos tipos de chile chipotle9</td> </tr><tr style="height:18px;"><td align="right" style="height:18px;width:136px;">10,000–23,000</td> <td style="height:18px;width:613px;">Chile serrano, chile de árbol, algunos tipos de chile chipotle</td> </tr><tr style="height:18px;"><td align="right" style="height:18px;width:136px;">5,000-15,000</td> <td style="height:18px;width:613px;">Chile Campana</td> </tr><tr style="height:21px;"><td align="right" style="height:21px;width:136px;">5,000–8,000</td> <td style="height:21px;width:613px;">Variedad de Nuevo Mexico del chile anaheim,10 chile húngaro de cera11</td> </tr><tr style="height:18px;"><td align="right" style="height:18px;width:136px;">2,500–5,000</td> <td style="height:18px;width:613px;">Chile jalapeño, Pimiento de Padrón,</td> </tr><tr style="height:18px;"><td align="right" style="height:18px;width:136px;">1,500–2,500</td> <td style="height:18px;width:613px;">Chile rocotillo, Salsa Sriracha</td> </tr><tr style="height:18px;"><td align="right" style="height:18px;width:136px;">1,000–1,500</td> <td style="height:18px;width:613px;">Chile poblano</td> </tr><tr style="height:21px;"><td align="right" style="height:21px;width:136px;">500–1,000</td> <td style="height:21px;width:613px;">Chile anaheim12</td> </tr><tr style="height:18px;"><td align="right" style="height:18px;width:136px;">100–500</td> <td style="height:18px;width:613px;">Pimiento, pepperoncini, pimienta banana</td> </tr><tr style="height:18px;"><td align="right" style="height:18px;width:136px;">0</td> <td style="height:18px;width:613px;">No picante, pimiento verde</td> </tr></tbody></table>

<div id="mntl-sc-block_1-0"> <h2>Plant seeds scarification</h2> Scarification in botany involves weakening, opening, or otherwise altering the coat of a seed to encourage germination. The seeds of many plant species are often impervious to water and gasses, thus preventing or delaying germination. Scarification is often done mechanically, thermally, and chemically. Seed scarification is scarring seeds. A seed's hard outer coat makes it impervious to gasses and moisture that would cause them to germinate. To overcome this you need to scratch, break or nick the seed coat. In nature, this naturally occurs when seeds pass through the digestive tract of some animals, through freezing temperatures or microbial activities that break down the seed coat. Seeds that need to be scarified before sowing are usually large or have thick seed coatings like seeds in the morning glory family, runner beans like purple hyacinth beans vine or canna seeds. The process of seed scarification can be accomplished by rubbing the seed on file or sandpaper. Be careful not to go too deep into the seed itself. Scratch the seeds just enough that you can see a difference is color of the seeds should be enough. Water is easily soaked up through the seed coat after you've done this. <h2>Methods of Scarification of Seeds</h2> Seeds with hard coats may need to be scarified - the process where the seed coat is modified in some way so that moisture can enter and germination occurs. <h2>There are several methods of scarification:</h2> </div> <ol style="list-style-type:upper-alpha;"><li>Soaking the seeds in hot water</li> <li>Damage hard outer seeds coat with Pliers, knife, nail clipper...</li> <li>Using a file or sandpaper (one must be careful to not go too deep and damage the embryo inside)</li> <li>Acid (this can be quite dangerous and you must follow directions carefully!).</li> </ol>The type of scarification will depend on which seeds you are germinating. <h2>Scarification Breaks Dormancy</h2> Physical dormancy is due to structural limitations to germination such as hard impervious seed coats. Under natural conditions weathering for a number of years weakens the seed coat. Certain seeds, such as the sweet pea, have a tough husk that can be artificially worn or weakened to render the seed coat permeable to gasses and water by scarification. In some tree species, dormancy is the result of a thick, hard seed coat that may be broken by scarification. In nature, the seed coat may be broken by microbial action, passage of the seed through the digestive tract of a bird or other animal, exposure to alternate freezing and thawing, or fire. <h2>Seed Stratification</h2> Seed stratification is sometimes better known as the cold stratification. The seed of many tree species will not germinate until they have been exposed to cool temperatures and moist conditions for several weeks or months. Gardeners can accomplish the same results indoors by a process called stratification. Tree seed can be stratified by placing the seed in a moist 50:50 mixture of sand and peat moss. Suitable containers include coffee cans, plastic jars, and cottage cheese containers. (Punch holes in the lid of the container to provide air.) Seed can also be stratified in plastic bags. Stratify the seed in the refrigerator. The seed of some trees, such as redbud, have hard impermeable seed coats and dormant embryos. They require both scarification and stratification for germination.
