In this macro stage, you need to pay attention to the germination of the seeds. Variety similarity remains at 60-80%, similarity of hybrids 92-98%. Field similarity is influenced by such factors as the selection of high-quality seed, quality seedbed preparation, seeding technique, seed treatment with micronutrients and favorable weather conditions.

It is worth noting that germination is the beginning of plant development. The duration of this stage starts from dormancy to the appearance of sprouts, i.e. until the first leaf sheath with a shoot appears on the soil surface.

During seed germination, water is absorbed by the embryo, resulting in rehydration and cell expansion. Soon after water absorption or absorption begins, the respiration rate increases, and various metabolic processes that were suspended or significantly reduced during the resting period are restored. All these events are associated with structural changes in the organelles (membrane bodies responsible for metabolism) in the cells of the embryo.

Since the spare materials are partially in an insoluble form, namely in the form of starch grains, protein granules, lipid droplets, etc., most of the early metabolism of seedlings is associated with the mobilization of these materials and the delivery or transfer of products to active sites. Stocks outside the embryo are digested by enzymes secreted by the embryo, and in some cases also by special endosperm cells. Active embryo growth, except that resulting from swelling, usually begins with the emergence of a primary root, known as a seed root, although in some species (e.g., coconut) a shoot or perunus emerges first.

Early growth depends mainly on cell expansion, but within a short time cell division begins in the root and young shoot, followed by growth and subsequent organ formation (organogenesis), which are based on the usual combination of increased cell number and increased individual cells.

In this macro stage, development from the first true leaf occurs and continues until there are nine or more true leaves. Also at this stage, rudimentary stem nodes and internodes are laid down.

The plant needs sufficient supplies of macronutrients such as phosphorus and potassium. When exposed to environmental and anthropogenic environments, amino acids must be used to eliminate them. The leaves originate on the sides of the top of the shoot. 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. Leaf support cells can be derived from the sheath or from the sheath and the casing. After that, the support becomes more and more flattened in the transverse plane due to laterally oriented cell divisions and subsequent expansion on both sides.

The zones of separation are the marginal meristems, the activity of which gives the leaf its lamellar shape. In each meristem, the outer array of cells or marginal initials contributes to the epidermal layers by prolonged separation. The cells below are submarginal initials and provide the tissue of the inner part of the leaf. Usually, a certain number of cell layers is defined in the mesophyll (the parenchyma between the epidermal layers of leaves). Cell division is not limited to the region of 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. Partitioning usually ends first in the epidermis, then in the lower layers of the leaf mesophyll.

Corn is a rather demanding crop for nutrition. It gives a large yield only where the soil is rich in nitrogen and other elements.

For the intensive growth and development of corn throughout the entire growing season, an optimal amount of macro- and microelements in an easily accessible form is necessary, and for their effective consumption – certain soil and climatic conditions: soil structure, temperature, humidity and content of mobile nutrients, the pH of the soil environment, air temperature and humidity, intensity of solar radiation, etc.

During the growing season, corn plants use nutrients unevenly. The assimilation of nitrogen lasts until waxy ripeness, and the maximum need for it is from the ejection of panicles to flowering. Phosphorus is absorbed almost until the grain is fully ripe. Plants use potassium most intensively in the first half of the growing season and during the formation and formation of grain.

The soil, even at a high level of fertility, is unable to provide such an amount of nutrients for a number of reasons. In particular, because of acidity, because nitrogen is assimilated in a very wide pH range – from 4 to 9, and phosphorus – only in neutral or close to neutral environment (pH from 6.6 to 7.5); the amount of moisture, since the roots are fed by the appropriate solutions; due to aeration, because the assimilation of macro- and microelements depends on the provision of oxygen to the soil, etc.

In conditions of unstable moisture, root feeding will not have an effect due to the rapid drying of the top layer of the soil, so it is better to use foliar feeding.

Wonder offers to consider a fertilizer for foliar nutrition which contains an increased amount of the necessary nitrogen in its composition:

  1. Wonder Leaf Violet (N:P:K-30:10:10 + SO3-15, Mo-0.5, w/w %).

Microelements are the basis of plant life

All processes of synthesis and transformation of substances in plant cells occur with the help of enzymes which include trace elements. They play a major role in the processes of synthesis of proteins, fats, carbohydrates and are part of vitamins, hormones and other biologically active substances.

Among trace elements, corn most of all needs Wonder Leaf Mono Zn 8 (Zn-8% chelate) which is part of many enzymes, participates in the formation of chlorophyll, promotes the synthesis of vitamins. This element plays an important role in oxidation-reduction processes, therefore zinc fertilization helps to enhance the growth of corn plants. Signs of zinc deficiency in plants are the development of interveinal chlorosis, retardation of plant growth, disruption of the grain ripening process.

Wonder Leaf Pink (B-20%) is one of the most important trace elements for the formation of corn yield. It affects the carbohydrate and protein exchange in plants, the formation of phytohormones-auxins. Also, this element is a cell generator, activates cell division and promotes the intensive development of young tissues, participates in the synthesis of DNA and RNA nucleic acids, the synthesis of chlorophyll and the assimilation of carbon dioxide.

Boron deficiency in corn disrupt the transport of carbohydrates to other organs of the plant, the process of photosynthesis, the development of the root system, inhibits the development of the growth point (meristematic cells).

Wonder Leaf Mono Cu 6 (Cu-6% chelate) is part of enzymes and participates in redox reactions, about 50% of it is contained in chloroplasts.

Copper deficiency disrupts the lignification of cell walls, reduces the intensity of respiration and photosynthesis. Signs of copper starvation in corn plants are manifested in the whitening and drying of leaf plates.

Wonder Leaf Mono Fe 10 (Fe 8.8% chelate) is involved in the functioning of the main elements of the electron transport chains of respiration and photosynthesis, the reduction of molecular nitrogen and nitrates to ammonia, catalyzes the initial stages of chlorophyll synthesis. Lack of iron leads to interveinal chlorosis of corn, yellowing of leaf plates, formation of small leaves, reduction of sugar content.

Wonder Leaf Mono Mn 11 (Mn-11% chelate) activates enzymes, participates in the photolysis of water, as a component of the photosynthetic system promotes the accumulation and movement of sugars from leaves to other organs of corn, stimulates the growth of new tissues at growth points. In its absence, the intensity of photosynthesis deteriorates sharply, the amount of carbohydrates and the release of oxygen decrease.

Wonder Leaf Mono Mo 3 (Mo-3%) is often called a trace element of nitrogen metabolism as it is a part of nitrate reductase and nitrogenase, participates in the formation of proteins. With a lack of this trace element, the metabolism is disturbed, the growth of corn is weakened, flowering is delayed, the leaves have a light yellow color, later turn brown and die.
