“…As for the germination speed index (Table 1D and Figure 4), there was a reduction in averages when applying the polymer on most of the treatments evaluated, with reduction not occurring only in slow drying at 3 and 6 months of storage and in quick drying after 3 months of storage. Similar results were observed by Holbig et al (2011) in onion seeds, comparing the use of polymer, polymer with fungicide, only fungicide and a witness. According to these authors, the coated seeds showed slower germination than uncoated seeds.…”

-The use of methods and technologies such as drying and film coating can bring significant contributions to the farmer. This experiment was conducted in order to evaluate the effect of drying and film coating on the physiological quality of eggplant seeds during storage. Hybrid seeds UGA MS1 produced by the company Hortiagro -Ijaci, MG were used. Seeds were subjected to two types of drying: slow (room temperature) and quick (oven with forced air circulation at 35 o C). The chemical treatment was performed with the Captan product at a dose of 250 grams per 100 kilograms of seed and for the recoating were used three doses of polymer: (0, 3 and 6 mL.kg -1 of seeds). The physiological quality of seeds was evaluated every three months until reaching the period of nine months using germination test, seedling emergence test and seedling establishment. There is a reduction of physiological seed quality during the storage. The slow drying of eggplant seeds results in better quality seeds. The use of polymer reduces the germination percentage, germination speed index and the percentage of seedling emergence.

“…The rapid initial growth of turnip seedlings favors the closure of the canopy, a characteristic of vital importance because this is a plant with a soil cover purpose. The best performances were observed with filming conditioned seeds in the presence of the organisms either separately or associated, opposing the results of Hölbig et al (2011) who observed that the use of films in filming tests with hydroponicated onion seeds impaired the vigor of seedlings. Similarly, a beneficial effect of physiological conditioning was also observed in the isolated microbiolization of B. subtilis, leading to a similar performance to that of chemical treatment.…”

The objective of this study was the effect of leverage microbiolization forage radish seed with Trichoderma spp. and Bacillus subtilis by physiological conditioning techniques, suspension of biological structures and film coating. The microbiolization suspension of biological structures was carried out with commercial products Rhizoliptus ® and Agrotrich plus ® . Fluid restriction was held in PDA medium + mannitol (-0.7 MPa), when was the first seed radicle protrusion in the other were removed and dried in a laboratory environment for 48 h. The film coating was performed with the addition of the polymer Color Seed ® (300 mL kg -1 ) treatment of the syrup containing Trichoderma spp. or product Rhizoliptus ® . We used a treatment covering the seeds primed with organisms, or their association. The microbiolization with Trichoderma spp. by physiological conditioning controls pathogens infecting the seeds. Trichoderma spp. and Bacillus subtilis promote the growth and development of seedlings of forage radish, and the coating of the seeds primed in the presence of organisms which provides greater shoot growth of seedlings in the field. Técnicas de microbiolização de sementes de nabo forrageiro com Trichoderma spp. e Bacillus subtilis RESUMO O objetivo deste trabalho foi potencializar o efeito da microbiolização de sementes de nabo forrageiro com Trichoderma spp. e Bacillus subtilis pelas técnicas de condicionamento fisiológico, suspensão de estruturas biológicas e peliculização. A microbiolização com suspensão de estruturas biológicas foi realizada com os produtos comerciais Agrotrich plus ® e Rhizoliptus ® . A restrição hídrica foi realizada em meio BDA + Manitol (-0,7 MPa), ao ocorrer protrusão radicular na primeira semente, as demais foram retiradas e secas em ambiente de laboratório por 48 h. A peliculização foi realizada com a adição do polímero Color Seed ® (300 mL kg -1 ) à calda de tratamento contendo Trichoderma spp. ou ao produto Rhizoliptus. Foi utilizado um tratamento recobrindo as sementes condicionadas com os organismos isolados ou em associação. A microbiolização com Trichoderma spp. pelo condicionamento fisiológico controla os patógenos infectantes das sementes. Trichoderma spp. e Bacillus subtilis promovem o crescimento e desenvolvimento de plântulas de nabo forrageiro, sendo o recobrimento das sementes condicionadas na presença dos organismos o que proporciona maior crescimento de parte aérea de plântulas no campo.

“…During film coating, the seeds are again exposed to hydration by the polymer application solution, reactivating the synthesis of enzymes and initiating the breakdown of nutrient reserves. Hölbig et al (2011) observed a similar effect; the film coating of hydroprimed onion seeds decreased seedling vigour.…”

The incorporation of biological control organisms in seeds may help control pathogens and improve seedling performance. The aim of this study was to determine the effects of biopriming bean seeds with Trichoderma spp. and Bacillus subtilis using physiological conditioning, suspensions of biological structures and film coating techniques. Biopriming treatments with suspensions of biological structures were performed using the commercial products Agrotrich plus ® and Rhizoliptus ® . Water restriction was achieved using a PDA + Manitol (−0.7 MPa) medium for both Trichoderma spp. and Bacillus subtilis. Fifty disinfected bean seeds were placed in each petri dish. When the first radicle protrusion appeared in a seed, the other seeds were removed and dried in the laboratory environment for 48 h. Film coating was performed with the addition of the Color Seed ® (150 mL kg −1 ) polymer to a treatment solution containing either the Trichoderma spp. or the Rhizoliptus product. Seeds were dried for 48 h in the laboratory. Seeds were covered and treated with one or both organisms. Biopriming with spore or bacterial cell suspensions promoted bean seedling growth, and the other techniques were not required to potentiate these benefits. Covering the primed bean seeds reduced seed quality. Both Trichoderma spp. and Bacillus subtilis promote bean seedling growth, benefitting the seedling even after it becomes independent of the seed reserves. ARTICLE HISTORY
