A method for stimulating the growth of spruce and strawberry in the early phases of development is proposed. A technology for obtaining plasma-activated water (PAW) with the help of a glow discharge plasma generator was developed. The method is proposed for increasing the shelf life of PAW by adding an aqueous colloid of polyvinylpyrralidone (PVP) polymer. It is shown that after treatment with a PAW + PVP mixture, the seeds have a higher percentage of germination, the plants develop faster in the early stages, and they are more viable. At the physicochemical level, after seed treatment with PAW + PVP, higher rates of metabolite outflow from seeds are observed. At the biological level, seed treatment with PAW + PVP leads to a slight decrease in the activity of antioxidant enzymes and a higher content of chlorophylls in the leaves, and a slightly higher assimilation rate is observed. In the leaves, there is higher content of the growth hormone indole-3-acetic acid (IAA), whereas the content of the growth-inhibiting hormone abscisic acid decreases. The use of a stimulating drug based on the composition of an aqueous solution activated by plasma and polyvinylpyrrolidone (PAW + PVP) polymer can be an effective means of a single pre-sowing treatment of spruce seeds in solving the problem of reforestation and strawberry during plant propagation.

The exogenous application of a 200 ppm solution increased the total phenol content six times, and a 50 ppm solution promoted the development of the onion bulb and increased its weight [5].

The search for new plant growth regulators is a cornerstone of agricultural research; however, laboratory studies rarely go on to be evaluated in the field. This is because greater production is required, as well as longer studies. Particularly, brassinosteroids present these difficulties, and although they have been evaluated in crops with good results, their high production cost gives rise to the search for new alternatives. 22-Oxocholestanes such as SPGP4, previously used in silico and in vitro studies, have shown great potential, so their evaluation in crops grown from native seeds from the study region becomes of interest. Based on these data, SPGP4 was evaluated under crop conditions in three agricultural plots located on the Isthmus of Tehuantepec region, Oaxaca, México. The seeds were treated with a 0.5 mg/L aqueous solution of the 22-Oxocholestane compound SPGP4 by imbibition one night before sown. Later, 45 days after sowing, a solution of 0.5 mg/L at a rate of 200 L per hectare was applied. At the production level, the bean harvest showed an increase in the range of 21.0–38.1%, and the corn harvest increased between 22 and 32%. In addition, the latter also demonstrated an increase in biomass production, given the increase in diameter and height observed in the corn plant. This indicates that SPGP4 functions as a regulator of plant growth at the crop level to increase both seed and biomass production.
