Mechanism of action
Gibberellic acids are a class of substances similar to organic acids obtained from the gibberella fungus. Under natural conditions, gibberellic acids are found in various plant tissues, but most of them are in seeds - they are necessary for awakening the seeds to ripen and grow the embryo. Each plant produces several dozen species of gibberellic acids, significantly less of them are found in cotyledons, even less in real leaves. The accumulation of gibberellic acids in plant tissues depends on the surrounding conditions, for example, lighting plays a significant role - during the day gibberellic acids are stored more than in the dark. The highest content of gibberellins in immature seeds, therefore, the purpose of stimulants containing organic acids is to remove seeds from rest, and first of all it is advisable to use them for seed germination. The properties of gibberellic acids allow them to be classified as phytohormones.
Use of Plodostim
When sprayed with Plodoslym, the active substance penetrates through the integument of the leaves, the plant receives a boost to growth:
- the growth of vegetative mass is stimulated: the main stem and lateral shoots, and in plants forming rosettes, the density and mass of rosettes increases
- flowering plants increase the number of ovaries, their preservation increases, more fruits are formed
- it is believed that Plodoslym is able to increase not only yield, but also stress resistance of plants, resistance to diseases, this happens due to the strengthening of the stem or a decrease in the distance between the nodes
- the effect of gibberellins on berry crops is especially valuable: for example, in grapes, spraying with Fruit 2-3 weeks before flowering leads to an elongation of the central axis of the grape bunch, an increase in its lateral branches, an increase in the size of berries and, accordingly, an increase in the weight of the grape bunch itself in
- some ornamental flowering plants (geranium, gardenia, hydrangea) Plodostim causes enlargement of flowers
Features of Gibberellin Growth Stimulants
The peculiarities of drugs such as Plodostim are that the exact function of using them to form a flower is not entirely clear to scientists, since all plants react differently to the use of this type of stimulants: there are flower cultures in which gibberellins do not contribute to the formation of a flower, for example, fuchsia delays flowering, but there is a more energetic growth of greenery, but cyclamens, on the contrary, bloom 1.5-2 weeks earlier after spraying, this is widely used in industrial flower greenhouses.
You need to know that although Plodostim is not phytotoxic, overdoses can be harmful: too high a concentration will lead to the formation of longer and weaker peduncles.
Instructions for use
