In this macro stage, it is necessary to pay attention to the fact that the seeds are similar. Similarity at the varietal level – 60-80%, similarity at the hybrid level – 92-98%. Field similarity is influenced by factors such as the selection of high-quality seed material, a qualitatively prepared seed bed, seeding technique, treatment of seeds with trace elements and favorable weather conditions.

Germination is the beginning of plant development. It is very important that its duration begins with a state of rest before the appearance of seedlings, in fact, until the shell of the first leaf with the shoot appears on the soil surface. In the process of germination of seeds, water is absorbed by the embryo, which leads to rehydration and to the expansion of cells. Soon after the start of water absorption or absorption, the respiratory rate increases, and various metabolic processes are restored, suspended or significantly reduced during the rest period. All these events are associated with structural changes in organelles (membrane bodies responsible for metabolism) and in the cells of the embryo.

Since spare materials are partially in undissolved form, namely in the form of starch grains, protein granules, lipid droplets and other substances, most of the early metabolism of sprouts is associated with the mobilization of these materials and the delivery or movement of products to active sites. Reserves outside the embryo are digested by enzymes.

The active growth of the embryo, with the exception of edema resulting from edema, usually begins with the appearance of the primary root, known as the root from the seeds, although in some species (for example, coconut) the shoot or feather appears first. The early growth of the embryo depends mainly on the expansion of the cell, but within a short time, cell division begins at the root and young shoot, and then growth and further formation of organs (organogenesis) are based on the usual combination, increase in the number of cells and increase in the number of individual cells, by the embryo, and in some cases also by special endosperm cells.

Foliar rosette forming

BBCH 13-19
Foliar rosette forming

This macro stage develops from the first true leaf and continues up to nine or more true leaves. First, the rudimentary stem nodes and internodes are established. The plant needs sufficient supplies of macronutrients such as phosphorus and potassium. When exposed to environmental and anthropogenic influences, amino acids are needed to eliminate them.

Leaves originate on the sides of the shoot tip. A local concentration of cell divisions marks the very beginning of the leaf; these cells then enlarge to form a nipple-shaped structure called a leaf support. The cells of the leaf support can be derived from the sheath or from the sheath and the hull. The support then becomes more and more flattened in the transverse plane due to laterally oriented cell divisions and subsequent expansion on both sides.

After that, the prop becomes more and more flattened in the transverse plane due to laterally oriented cell divisions and subsequent expansion on both sides. The dividing zones are the marginal meristems, through the activity of which the leaf acquires its lamellar shape. In each meristem, the outer array of cells or marginal initials contribute to the epidermal layers by prolonged division. The cells below, the submarginal initials, provide the tissue of the inner part of the leaf.

Usually, a certain number of cell layers are defined in the mesophyll (the parenchyma between the epidermal layers of the leaf). Cell division is not limited to the region of the marginal meristems, but continues throughout the leaf in each of the layers, always in the same plane, until the final cell number is approached. Then the rate decreases, terminating in different layers at different times. The divisions usually end first in the epidermis, then in the lower layers of the leaf mesophyll.

Foliar rosette and stem forming

During the development of the indicated macro stage, the differentiation of the main axis of the germinal inflorescence occurs. The actual number of flowers is determined. During the period of intensive development from the phase of formation of lateral shoots/bushing to the phase of flowering it is necessary to have enough of these types of reserves: macro-, meso- and microelements for the full development of all plant organs.

The shoots of most vascular plants branch out according to a sequential plan, with actually each new axis arising at an angle between the leaf and the stem, i.e. in the leaf axil. In some plants, buds may also be formed from older parts of the shoot or root distant from the main apices; these buds, called adventitious buds, do not follow the general plan. The apex of the lateral shoot begins on the sides of the main apex, but some distance below the point of emergence of the youngest leaf rudiment.

As in the origin of the leaf, usually the outer cell layers contribute to the surface tissues of the new apex, maintaining a consistent pattern of divisions. In some species, a sheath of more than one cell layer quickly forms, so that the new apex looks like a miniature version of the main one.

Alternatively, differentiation cannot become evident until a significant mass of the new initial state has been reached. In all cases, the new apex must reach a minimum volume before it can, in turn, begin to form its lateral rudiments and organize true axillary buds. When this size is reached, zoning occurs.

Like the beginning of the main apex, the formation of new rudiments is associated with the annular zone. From this point, the development of a lateral shoot is the same as the development of the main shoot, except that growth may not be as fast, because the main apex or leading bud dominates and absorbs most of the available nutrients.

Early axillary bud growth is quite vigorous until a certain number of leaf buds are formed; then the apex activity slows down. Cell division gradually ceases, and with it the associated syntheses; thus, there is no increase in DNA of meristem nuclei after the last division. The kidney essentially goes into a dormant state, even if external conditions for growth are favorable. This phenomenon is known as correlative bud oppression, because it is determined by the activity of the conducting bud of the shoot. If the main, i.e. leading bud is removed, the inhibited lateral buds restore growth, and with it all associated syntheses.

In the above macro stage, the formation of all the organs of the inflorescence of the flower, development from the rudiments of already formed flowers, up to their opening, is completed. The largest upper internode continues to grow. Complex fertilizers with an emphasis on nitrogen and microelement such as zinc continue to be applied.

It is worth indicating that in terms of development, the flower can be considered as a determinate growth axis, but the lateral members occupy areas of the leaves that differentiate as floral organs, namely sepals, petals, stamens and uteri.

In the transition to flowering, the stems undergo characteristic changes, the most noticeable of which is the shape of the apical region, which is related to the type of structure to be formed, either already as a separate flower, such as in the tulip, or as a brush of flowers (inflorescence), as in the siren. The area of cell division extends to the whole apex, and the RNA content of the end cells increases. When the formation of a single flower occurs, in fact the lateral rudiments appear higher and higher on the sides of the apical dome, and the whole apex is absorbed in the described process, after which the apical growth ceases.

BBCH 71-79
Fruit and seeds formation

As for this macro stage, it is the growth and formation of the fruit and seeds. The embryo and endosperm increase in its size. Fruit and seed size (length is typical for variety and hybrid).

Fruit and seed mass and quality can be influenced by complex fertilizers, calcium and trace elements. The fruit is formed from the ovary of the pistil after fertilization and is a characteristic feature of a flowering plant. A sharp increase in ovary cell division is observed after pollination. Then comes the phase of cell stretching.

That is, the nature of growth is in close dependence on the type of fruit. After pollination, cell division continues for some time. Further increase in size occurs through stretching. Fertilized egg, endosperm and developing seeds have a strong controlling influence on fruit growth. For example, underdeveloped seeds, for certain reasons, cause premature fruit drop. In fact, uneven seed development leads to fruit deformation.

Rapeseed ranks third among oil crops. Its gross production is about 33-35 million tons, and oil production reaches 9.8% of world volumes. Rapeseed is grown in more than 30 countries of the world, 30 million hectares, or 10.5% of all areas of oil crops are allocated for sowing. In Europe, this crop occupies almost 4 million hectares. Thus, in Germany, one of the leading rapeseed countries, 10-11% of the total sown area is allocated to it.

Winter rape is a plant of a temperate climate, light- and moisture-loving. It, like every crop, is characterized by optimal values and biological minimums of the main agrometeorological parameters: solar radiation, heat and moisture. The highest yield of rapeseed is formed when the needs of plants are fully met, under optimal values of environmental factors, a large part of which is meteorological values.

Rape requires fertile soils with medium humus content and a neutral or slightly acidic reaction of the soil solution. The most suitable for its cultivation are dark gray and gray forest soils, black soils, sod-podzolic, sod and sod-loamy soils with a light and medium loamy texture.

Nutrient supply is a determining factor for the good development of rapeseed, its winter hardiness, resistance to diseases and pests. For the formation of 1 ton of crop, rapeseed takes from the soil: nitrogen – 45-80 kg; phosphorus – 18-40 kg; potassium – 25-100 kg; calcium – 30-150 kg; magnesium – 5-15 kg; sulfur – 30-45 kg.

Rapeseed absorbs about 15-25% of nutrients from soil reserves, and the rest should be applied in the form of organic and mineral fertilizers.

Full use of mineral nutrients by plants is possible only if all elements are provided. The lack of one of them inhibits the assimilation of others and ultimately negatively affects the yield.

Like all cruciferous plants, rapeseed has a high need for nitrogen. It is manifested from the beginning of vegetation to budding. Of the total amount of nitrogen in the fall, plants use about 20%, 36% at the beginning of vegetation recovery, 31% at the beginning of flowering, and 10% at the end of flowering. Based on this, it is advisable to apply no more than 25% (25-30 kg/ha) of nitrogen from the total need for winter rapeseed in autumn.

In order to avoid nitrogen deficiency in rapeseed, we recommend using Wonder Leaf Violet fertilizer (N:P:K-30:10:10 + SO3-15, Mo-0.5, w/w %).

Phosphorus is necessary for the development of a good root system, increase of seed productivity, acceleration of maturation, prevents plant dormancy. This nutrient is obtained mainly from soil reserves (70-80%). If the phosphorus content is lower than the specified norm, there is a need for its additional application.

To avoid phosphorus deficiency, we recommend using Wonder Leaf Blue fertilizers (N:P:K-10:53:10 + Zn-2 chelate , w/w %), or Wonder Leaf P 30 (N:P-4:30 + B-0.5, Zn -0.5 chelate, amino acids-1, organic acids-4, w/w %).

Rapeseed plants can absorb up to 300 kg of K 2 0 per hectare, and during the autumn period – up to 70 kg. Plants need the most potassium during autumn development and before flowering. The lack of this element delays the growth of stems, the development of the root system, reduces the frost resistance of crops, the oiliness of seeds, increases the tendency to lay down, and contributes to the appearance of reddish-brown spots on the leaves. Sufficient provision of plants with potassium enhances nectar production.

To avoid potassium deficiency, we recommend using Wonder fertilizer Leaf Red (N:P:K-10:20:30 + B-2, w/w %); no less important for the formation of a high- oil rapeseed crop are trace elements.

Manganese Wonder Leaf Mono Mn 11 (Mn-11% chelate) increases winter resistance, affects the accumulation of sugars in plants and participates in nitrogen and phosphorus metabolism.

Fertilizers containing boron: Wonder Leaf Mono B 11 (B-11%), or Wonder Leaf Mono B 120 (B-9%), or Wonder Leaf Pink (B-20%) promotes the growth and development of the root system, growth points, increases the accumulation of sugars and other high-energy substances, ensures their transportation to the root neck. It also improves frost and winter resistance of the plant and wintering as a whole, significantly affects the processes of pollination and fertilization, accelerating the germination of pollen and contributing to the formation of the generative apparatus of plants.

Sulfur in the composition Wonder Leaf MgS 16-32 (MgO-16, SO3-32, Mn-0.007 w/w %) is part of amino acids, fatty acids, vitamins, participates in the production of chlorophyll. Its deficiency inhibits protein synthesis, slows down plant growth, reduces the number of pods on a plant and seeds in pods, and the quality of seeds deteriorates due to a decrease in oil content. Another important function of sulfur in plant metabolism is to increase resistance to fungal pathogens.

Molybdenum in Wonder Leaf Mono Mo 3 (Mo-3%) takes part in carbohydrate metabolism and in the metabolism of nitrogenous compounds, synthesis of vitamins and chlorophyll, improves nutrition of plants with calcium and iron.

For the formation of 1 ton of main and by-products of rapeseed (kg/ha): Mg – 7-12; Mn – 0.2-0.5; B – 0.3-0.6; Mo – 0.001 -0.002; S – 0.06-0.15; Cu – 0.01 -0.04.

The following periods are critical for rapeseed in terms of nutrition: phase of 4-8 leaves VVSN 14-18 (in autumn – for winter rapeseed); phase of 8-12 leaves stemming ( VVSN 30-39); budding – flowering ( VVSN 59-63).
