Introduction to Flaxseed germination procedure

Flax is a member of the genus Linum in the Linaceae family. Equal substitution is not possible because flax does not have any gluten, resulting in products with less volume. Where gluten is less of a factor, like muffins and sweetbreads, more flax can be used.  Whole Flaxseeds have a shiny, hard outer coating that can make it difficult for the body to break down. Flax is also called linseed. The nutrients in whole Flaxseeds are less obtainable when the seeds are eaten unsoaked in some cases; the seeds can pass whole through the body. In other instances, such as when flax is used as an egg substitute, soaking is required to take advantage of the seeds’ fiber content. In this article we also discussed below topics;

A step by step guide to the Flaxseed germination process

A seed germination process is a complicated event, with different phases of the process affected by temperature, moisture, and oxygen. Temperature is the main factor regulating the germination of nondormant seeds in irrigated, annual agro-ecosystems at the beginning of the growing season where light, nutrients, and moisture are not growth limiting. Flax is highly self-pollinating, with outcrossing rates from about 0.3 to 2.0% under normal circumstances. Insects are the main agents of outcrossing.

The life cycle of the flax plant contains a 45 to 60-day vegetative period; a 15 to 25-day flowering period; and a maturation period of 30 to 40 days. Though there is a period of intense flowering, a small number of flowers may continue to appear right up to maturity. Maturity is delayed under cool, wet conditions and the crop lifecycle from seeding to maturity is 90 to 125 days, depending on overall environmental conditions. Drought, high temperature, and disease can shorten the growth period and flax crop lifecycle. If ripening occurs under high soil moisture and fertility conditions, stems can remain green and new growth may result in the second period of intense flowering. Some Canadian flax varieties are determinate and resist reflowering. Maturity will be delayed under cooler than normal growing conditions, at higher altitudes characterized by lower heat units, or in the northern prairies. Under these conditions, the lifecycle can be extended to over 125 days.

The soil recommendation for Flaxseed germination

The soil for Flaxseed germination.

The flax plant is best adapted to fertile, fine-textured, clay soils. It should not be grown on coarse-textured, sandy soils. Flax on peat or muck soils can be disappointing unless problems related to drainage, fertility, and weed control are solved.

The seed preparation for Flaxseed germination

More uniform stands of flax are frequently obtained when the Flaxseed is treated with a suitable fungicide. In areas where wireworms are a problem, an insecticide requires to be used along with a fungicide as a seed treatment. The seed coat of flax is simply damaged during harvest and handling. Sometimes the damage is so slight it is not visible but even such slightly damaged seed is susceptible to seed decay. Thus, all seeds must be treated with a fungicide. Sound, uninjured Flaxseed always selected for planting if available.

About Flaxseeds

Flaxseeds are flat, oval, and pointed at one end. A thousand seeds weigh from 5 to 7 g, depending on variety and growing conditions. Canadian Flaxseed varieties range in color from light brown to dark reddish-brown or yellow. Mottled seed, a combination of yellow and brown on the same seed, can be the result of environmental conditions.

The Flaxseed is covered with a coating (mucilage) that gives it a high shine and causes the seed to become sticky when wet. At times, this mucilage absorbs moisture from the air, causing the mature Flaxseeds to stick to the boll surface. This removes the shine on the seeds, giving them a scabby appearance which could result in a reduced grade.

Find the seeds of the correct Flax species

There are hundreds of species of Linum in the world and only two blue species are commonly grown in gardens. These mainly look similar in appearance and are only identifiable to a beginning botanist or gardener by the life cycle of the plant. One is annual it germinates (sprouts from seed), grows, and flowers then die within a year. The other species is a perennial plant meaning it flowers and survives the remaining season as a dormant (sleeping) root and comes back for many years in suitable climates. Both species look similar with 2 to 4 feet tall arching stems with greyish-blue green needle-like leaves that look somewhat like a blue spruce sapling but soft and flexible. These plants have a deep taproot shaped like a skinny carrot and don’t like being transplanted (moved) once established. Early summer to late summer the plant produces beautiful 5 petaled sky blue flowers that last only a day each but are produced in such large numbers from hanging tear-shaped buds that the plant is covered in blooms for 1 to 3 months.

Common Flax is the one that’s used for making linen fabric and linseed oil used as food. The Flaxseed of this species is used for food consumption as well. This plant is the annual and Perennial Flax is the almost exact twin. Other flax species produce red (Linum grandiflorum) pink and yellow flowers as well.

The spacing for Flaxseeds or Flaxseed plant distance

Ideally, flax must be sown into moist soil, 1.0 to 1.5 inches deep with row spacing 6 to 8 inches. Flax seedlings are weaker and shallow seeding depth is critical for vigorous emergence, however, too shallow and seeds can be prone to drought.

The sprouting medium for Flaxseed germination

Flaxseeds are a little difficult to sprout that other seeds because of their mucilage. When water is added to the Flaxseeds, the hard hulls absorb the water and form a “gel-sack” around each seed. And these slippery seeds will not sprout in traditional, water-only methods, like other seeds. They should be sprouted on a medium, such as a paper towel, or purchased vermiculite medium. You must sparely spread the seeds on the thoroughly moistened medium.

Seedbed preparation for Flaxseed

The best seedbed for flax is similar to the seedbed for small-seeded grasses. It must be well worked. The soil must be firm to avoid large air pockets. Fall plowing is preferred if erosion is not serious. The seedbed can be worked fairly shallowly, except where deeper plowing is required when flax follows corn. Flax cultivation following early fall plowing will aid in weed control. In the spring, shallow discing and harrowing are the practices of seedbed preparation. In most cases, more uniform planting depth and seedling emergence will result if the field is rolled before planting.

Seeding date and method for Flaxseed germination

Early seeding gives the highest yields in most years and plant about the same time as for oats. Seedling flax plants have the tolerance to light frost. Planting is sometimes delayed to allow cultivation for weed control in fields where weeds can be a very serious problem. Late planting of flax could not cause as great a yield reduction as it does with small grains.

A seeding rate of 42 to 50 pounds of good seed per acre is recommended. Lower seeding rates result in more severe weed problems. About one–half to one-inch planting depth is suggested in clay soils and seed is comparatively small and fails to emerge from greater depths, especially if crusting occurs. Inexperienced growers often plant too deep, particularly if the soil is loose. Flax is generally sown with a grain drill. Press wheel-type grain drills are ideal and a roller type seeder often used to plant forage legumes may also be used.

Flaxseed germination time and temperature

The minimum soil temperature for Flaxseed germination is 7-10°C. Watch for the Flaxseeds to germinate in about 10 days. Water the Flaxseeds regularly to keep the soil evenly moist, but not drenched.

Flaxseed soaking and its benefits

The amount of time your Flaxseeds should soak in cool water. Seed soaking is how we begin the sprouting process in most cases.

The soluble fiber on the exterior of the seed is softened during even short periods of soaking. In addition to softening the seeds, the soaking procedure removes substances such as phytic acid and tannins that are hard on your digestive system. Soaking Flaxseeds can make some nutrients, such as protein, more available, and the seeds easier to digest in general.

The seed soaking process for Flaxseeds

Sources of Flaxseed

Purchase Flaxseeds in health food stores, grocery stores, and bulk food stores. If possible, select Flaxseeds that have been packaged in an air-tight, opaque container. While whole Flaxseeds can stay fresh for up to 1 year, their high oil content means they can go rancid after a time. Look for shiny, unbroken Flaxseeds. You can use golden yellow or dark brown Flaxseeds for soaking.

Using soaked Flaxseeds

Soaked Flaxseeds can be used the same way as unsoaked seeds. Sprinkle the soaked seeds over the top of baked goods, into salads, soups, or add them to smoothies for a quick, nutritious boost to a meal or dish. You can store soaked, unused Flaxseeds in an air-tight container in the fridge for five days. If you are using Flaxseeds as an egg replacement, you should use soaked seeds, as the softened soluble fiber around the hull is required to mimic egg’s natural viscosity.

To soak, cover the Flaxseeds with at least 1 inch of water and cover the bowl with plastic wrap and let sit. Soak whole seeds for as little as 10 minutes or for as long as overnight. The cooler the water is, the more time the Flaxseeds need to be soaked. For water that is around room temperature, 21°C, soak for a minimum of 2 hours and a maximum of 4 hours. In warm water, seed soaks for at least 10 minutes, up to 30 minutes. Use the soaking liquid for cooking or baking to take full benefit of the nutritional and health benefits of flax.

Conditions for Flaxseed germination

Flaxseed crop.

Grow the Flaxseeds on the medium in a room temperature range of 21°C, with indirect sunlight. The seeds will begin to sprout in 24 hours and approximately 5 to 14 days, show signs of small green leaves. As the seed sprouts grow, keep them moist with a spray bottle of water. Check daily and make sure they do not dry out, which is dependent on the amount of sunlight in the room. Growing Flaxseed on a commercial level can be a complicated procedure, but planting flax from seed in your garden is easier than you may think. You’ve grown its wildflower cousins, blue flax and scarlet flax before, or know someone who has.

Common flax, like its cousins, is a cool-season plant, and the seeds must be planted as soon as the ground can be worked in spring. A late frost won’t harm the plants once they emerge, as seedlings with at least 2 leaves can tolerate temperatures as low as -2°C. Look for a sunny location, sheltered planting site when planting flax from seed. Though flax will adapt to most well-drained soil types, rich soil is optimum. Dig in a generous amount of compost, manure, or other organic matter, particularly if your soil is poor. Work the soil well and smooth it with a rake, and then sprinkle the seeds evenly over the prepared soil at a rate of about 1 tablespoon (15 mL.) of Flaxseeds for every 10 square feet (1 sq. m.) of planting space.

Dusting the tiny Flaxseeds with flour before planting will make them easier to see. Rake the soil lightly so the seeds are covered with no more than about ½ inch (1.5 cm.) of soil, and then water the area, using a fine spray to prevent washing the seeds from the soil. Watch for the Flaxseeds to germinate in about 10 days. Water the Flaxseeds regularly to keep the soil evenly moist, but not drenched. Once the plants are established, supplemental irrigation is needed during periods of warm, dry, or windy weather. A thin layer of mulch will help control weeds while moderating soil moisture and temperature range. Generally, established flax plants will choke out weeds; however, regular weeding is critical when the plants are small. And work carefully, pulling by hand to avoid damaging the tiny flax roots.

Flax plants don’t necessarily need fertilizer, but if your soil is poor, the plants will benefit from a diluted solution of water-soluble fertilizer every two weeks until seed heads appear. At this point, withhold water so the Flaxseed heads ripen and turn golden yellow. Harvest the Flaxseeds by pulling entire plants up by their roots. Bundle the stems and hang them in a dry place for 3 to 5 weeks, or until the seed heads are completely dry. Flax plants are easy to grow. As wildflowers, they need little care. In the home garden, mulch around them to help retain soil moisture, and keep the weeds down. Prune Flax plants to promote good air circulation.

Pre-treatment for Flaxseeds

Flaxseeds can be soaked in water before use and soak seeds for 10 minutes in warm water or two hours in 20°C water (although some bakers prefer to soak Flaxseeds overnight). After seed soaking, the water turns opaque and slightly viscose from the soluble fiber and gums found on the surface of the seed. Add this water to the bakery mix to retain the maximum inherent advantage and functional properties found in flax.
