“…These results qualify the polymers used, since one of the criteria for the materials used as seed coat film is that they do not react negatively with the chemicals and do not affect the physiological quality (ROY et al, 2014), thereby corroborating the results found by Castañeda et al (2014), Keawkham et al (2014) and Melo et al (2015), where no changes were observed in the physiological potential of rice seeds and other agricultural species when they were treated with phytosanitary and polymer coatings. For soybean seeds, Verma and Verma (2014) considered the benefits of the association and compatibility of the polymer material with the fungicide, resulting in higher percentages of germination.…”

-The use of chemical seed treatment is an important tool in the protection of seedlings and has contributed to the increase of rice yield (Oryza sativa L.). The objective of this study was to evaluate the physiological quality and quantify the retention of chemical products in rice seeds treated with insecticide and fungicide coated with polymers. Six seed treatments were used: control, phytosanitary treatment and phytosanitary treatment and coating with the polymers, Florite 1127 ® and VermDynaseed ® polymers were efficient at retaining thiamethoxam in the rice seeds, preventing some of the active ingredients of the insecticide from being leached through the sand columns immediately after the simulated pluvial precipitation.

“…The chosen priming method was a proxy of the actual approach carried out by end-user farmers and in industrial seed treatment [27][28][29][30]. Such as in practical seed treatment, the procedure intends to transfer the coating to the seed surface rather than trigging seed germination during priming.…”

Zinc nanocoated seeds: an alternative to boost soybean seed germination and seedling development

et al. 2020

In this study, we characterized Zn seed coats adhered on soybean seed surface [Glycine max (L.) Merrill] and then investigated the effects of such coatings on germination and finally monitored the transference of Zn from the coatings to the seedlings. For that, seeds were coated with ZnSO 4 , 40 nm ZnO, and 5 µm ZnO at 4 mg of Zn per kg of seed. The shape and homogeneity of Zn deposits on the seed surface depended on the type of Zn source. X-ray spectroscopy unraveled that before the germination, Zn neither crossed the seed coat nor was biotransformed. Regardless of the particle size, ZnO-based treatments increased germination ratio, seedlings root, and shoot development, whereas ZnSO 4 suppressed them. After sowing, most of Zn on the seed coat was transferred to soil, while less than 13 wt% was assimilated by the seedling 14 days after sowing. Either this minor fraction of Zn was taken up during the imbibition process or absorbed by during seedling growth. Zinc oxide-based treatments represent a viable alternative to Zn supply in order to boost soybean germination and seedling development.

“…The [28] studying the coating of tomato seeds with increasing concentrations of synthetic polymer, noted that the film coating did not change the biometric variables related to the growth of seedlings. Already [29] also reported that the growth of carrot plants was not affected by the seed coat.…”

Plathymenia reticulata Benth belongs to the family Fabaceae. It has its own hardwood for luxury furniture, and it is also used in construction. The coating consists in applying thin and uniform layers of inert adhesive mechanism in order to increase the seed size, altering his shape, texture and color, in addition to enabling common use of nutrients, fungicides, insecticides and microorganisms beneficial. The goal of this study was to evaluate the physical and physiological seed's quality of mahogany coated with different doses of fertilizer. The treatments were: T1: sand + lime; T2: sand + lime + 25 g of fertilizer; T3: sand + lime + 50 g of fertilizer; T4: sand + lime + 75 g of fertilizer; T5: sand + lime + 100 g of fertilizer, and control with uncoated seeds. Later, the seeds were evaluated in laboratory and greenhouse. The coating increased up to 91% weight of one thousand seeds without the treatment coated fertilizer. The presence of nutrient seed coating decreases his germination. The doses of fertilizer used were harmful to germination, IVG, emergency and IVE, but did not affect seedlings development.
