Abstract: In soybean crops, industrial seed treatment is widely adopted, and it has allowed the development of new technologies, such as the use of dry powders. This work aimed to evaluate the effect of the industrial treatment, with and without the additional application of dry powder, on the physiological potential of soybean seeds. The experimental design was completely randomized, in a 4×2 factorial scheme, with four replications. Four chemical treatments were evaluated: 1) control, 2) carbendazim + thiram + thiamethoxam, 3) carbendazim + thiram, 4) thiamethoxam. Each trial was divided into one group that was treated and the other that remained untreated with the dry powder. The cultivars BRS 360 RR and BRS 284 were used and analyzed separately. The physiological potential of the seeds was determined by the following assessments: germination, first germination count, seedling emergence in sand, seedling total length, shoot length, and root length. Soybean cultivars respond differently to seed chemical treatments, regarding the effects on physiological potential. Using the dry powder results in problems in seed germination speed in the cultivar BRS 284. In the cultivar BRS 360 RR, the use of dry powder associated with thiamethoxam treatment reduces the physiological potential of the seeds.

The industrial treatment of seeds has favored the development of new technologies such as the use of dry powder. It has made application of spray volumes higher than those used in the conventional treatment. Therefore, this study aimed to assess the effect of industrial treatments at different spray volumes with and without application of dry powder on physiological quality of soybean seeds. A completely randomized experimental design was performed with four replications in a 5 x 2 factorial arrangement for cultivars BRS 359 RR and BRS 284. The factors were five spray volumes (0, 600, 1200, 1800 and 2400 mL. 100 kg-1) with and without the application of dry powder. The products used to obtain the volumes were fungicides (carbendazim + thiram); insecticides (imidacloprid + thiodicarb); nematicide (abamectin); micronutrients (cobalt, molybdenum and zinc); polymer (peridiam); biostimulant (kinetin + gibberellic acid + 4-indol-3-ylbutyric acid) and inoculant (Bradyrhizobium japonicum). The physiological quality of the seeds was determined by the following assessments: germination, first count of germination test, seedling emergence in sand, emergence speed index, and total length of the seedling shoot and root. The results showed that increased spray volume associated with the application of dry powder in seed treatment reduced the physiological quality of soybean seeds, and spray volumes up to 1200 mL 100 kg-1 in seed treatment without the application of dry powder do not impact the emergence and establishment of soybean seedlings.

Seed treatment with insecticides and fungicides has become an important practice for ensuring initial plant stand in establishing crops. In this context, the aim of this study was to evaluate the influence of chemical seed treatment with insecticides and fungicides on the physiological quality and health of the seeds of wheat cultivars. Seeds of the wheat cultivars BRS Pardela and BRS Gaivota were used, subjected to the following chemical treatments: 1- control, 2- carboxin + thiram + imidacloprid + thiodicarb, 3- carbendazim + thiram + imidacloprid + thiodicarb, 4- fipronil + thiophanate-methyl + pyraclostrobin, 5- triadimenol + imidacloprid + thiodicarb, 6- fipronil, and 7- imidacloprid + thiodicarb. Physiological quality was evaluated by tests of germination, accelerated aging, the length and dry weight of shoots and roots, and seedling emergence in the field. Seed health quality was evaluated by the blotter test method. The seeds of the wheat cultivars tested respond differently to the chemical treatments in regard to effects on germination and vigor. The treatment with triadimenol + imidacloprid + thiodicarb is harmful to seedling development. For the BRS Gaivota cultivar, the seed treatment with carboxin + thiram + imidacloprid + thiodicarb; and carbendazim + thiram + imidacloprid + thiodicarb improved seedling establishment in the field compared to the control.

Soybean seed treatment contributes to the maintenance of seed quality, but the effect of commercial formulations and chemical products on the effectiveness of the electrical conductivity test based on electrolyte leaching has been frequently questioned. This study aimed to verify the interference of the chemical seed treatment of two soybean cultivars on the effectiveness of the electrical conductivity test in evaluating the vigor of freshly treated and stored seeds. The experimental design was completely randomized, consisting of seven seed treatments and two evaluation periods (0 and 60 days after storage), with four replications. The used seed treatments consisted of 1) fipronil + pyraclostrobin + thiophanate-methyl, 2) imidacloprid + thiodicarb + carbendazim + thiram, 3) abamectin + thiamethoxan + fludioxonil + mefenoxam + thiabendazole, 4) carbendazim + thiram, 5) fludioxonil + mefenoxam + thiabendazole, 6) carboxin + thiram, and 7) control (no treatment). The cultivars were BRS 360 RR and BRS 284, which were analyzed separately. Germination, accelerated aging, emergence, and electrical conductivity tests were carried out. No differences were detected between the control and chemical treatments performed on seeds of the two freshly treated soybean cultivars regarding germination, accelerated aging, and emergence tests. The germination test stood out after storage with the cultivar BRS 360 RR, showing the maintenance of germination potential for seeds treated with carbendazim + thiram and the control treatment. Therefore, the chemical treatment of soybean seeds interferes with the result of the electrical conductivity test. The electrical conductivity test is effective in segregating seed lots in terms of vigor level. The electrical conductivity test correlates with the other vigor tests used to identify the reduction in the physiological seed quality with storage.

The aim of this study was to analyze soybean seed physiological quality after being subjected to various mixtures of pesticides via industrial seed treatment. The experiment was performed at the seed laboratory of the company BioGrow, located at São Paulo-SP, using soybean seeds cultivar NS 6700 IPRO which were subjected to 11 different treatments. Seed treatment was carried out using a treater Momesso, model L5-K, calibrated to apply a spray volume of 0.5 L 100 kg-1 of seeds in which the volume of each treatment was adjusted using distilled water. After treatment, seeds were spread over plastic strays for drying for a period of 24 hours under environmental conditions. Once dry, seeds were packed in paper bags and stored for 0 (control), 45, 90, 135 and 180 days, under uncontrolled conditions of temperature and relative humidity, when seed physiological quality was evaluated using the following tests: germination, accelerated aging, seedling emergence, speed of emergence index and speed of emergence. Soybean industrial seed treatment before storage for up to 180 days is practicable using the mixtures of pesticides tested for storing seeds under environmental conditions. All treatments tested contribute to the maintenance of seed quality throughout storage.

Seed Cryopreservation

Hibiscus acetosella (Malvaceae) is a shrub of great importance for landscaping, food and medicinal purposes. The objective of this study was to preserve H. acetosella germplasm by seed cryopreservation. Half of the seed batch was scarified and the other half was kept intact. Cryopreservation occurred by immersion in liquid nitrogen for 1 hour. Moisture content (MC%), germination percentage (G%), germination speed index (GSI), normal seedling formation (NS%), shoot length (SL), dry matter (DM), biometry and plant survival were evaluated after treatment. MC% ranged between 7.7% and 6.65% in intact and scarified seeds, respectively. Scarification raised G% and GSI compared to intact seeds. Intact and scarified seeds had 100% and 70% NS%, respectively, when not cryopreserved. Cryopreservation reduced NS% to 62% and 12.75%, respectively. The highest SL was observed in intact and non-cryopreserved seeds, with an average of 10.21 cm in height. However, the cryopreservation of intact seeds reduced SL by about 50%, and scarification led to a further reduction, either with (3.32 cm) or without (2.47 cm) cryopreservation. Seedlings from intact and non-cryopreserved seeds showed higher DM in relation to seedlings from cryopreserved seeds. The association of cryopreservation and scarification further reduced DM. The cryopreservation of intact seeds yielded 100% survival at the end of the acclimatization process. However, cryopreservation of scarified seeds reduced the survival percentage to 15%. Changes in color were observed for seeds scarified and subjected to cryopreservation. Thus, cryopreservation is considered an efficient technique for the conservation of intact H. acetosella seeds in the long term.

ABSTRACT New technologies are being incorporated to the seed treatment process, such as the use of products on industrial scale. This study aimed at evaluating the seed quality of wheat cultivars, as well as the influence of the seed treatment method on the establishment and yield of this crop. Seeds of the cultivars Jadeite 11, Quartzo and Tec Frontale were treated with the Spectro® fungicide (difenoconazole - 200 mL 100 kg-1 of seeds), Cruiser Opti® insecticide (thiamethoxam + lambda-cyhalothrin - 200 mL 100 kg-1 of seeds) and Polifix G4 polymer (100 mL 100 kg-1 of seeds). A completely randomized design, with four replicates, was used. The treatments consisted of industrial treatment, on farm treatment with the same products and control. Germination, first germination count and moisture content tests were carried out immediately after the seed treatment and at 30, 90 and 150 days of storage. Seedling emergence in beds was evaluated at 30, 60 and 120 days of storage. Under a randomized block design, seedling emergence and grain yield were evaluated in the field in two sowing seasons. The conventional or industrial seed treatment methods do not reduce the physiological quality and emergence of high-vigor seeds stored for 150 days, under controlled conditions of temperature and humidity. The conventional or industrial seed treatment with diphenoconazole + thiamethoxam + lambda-cyhalothrin + polymer does not increase the wheat crop plant stand and grain yield.

The objective of this work was to evaluate the effects on the physiological attributes of soybean seeds submitted to the seed treatment with addition of insecticide, polymers and micronutrients throughout the storage. The experimental design was completely randomized in a factorial scheme, with four seed treatments per two seasons of storage of the seeds. The analysis of variance revealed a significant interaction among seed treatments and storage times for both cultivars at 5% of probability, referring to the characteristics of shoot length (SL), primary root length (RL), shoot dry mass (SDM) and dry mass of the primary root (RDM) for the cultivar Fundacep 37 RR. Addition of seed treatments influences the physiological performance of seedlings originated from soybean seeds stored for 240 days. The shoot and primary root lenghts, and shoot dry mass express the isoenzyme esterase through the aerial part and primary root of the seedling, the malate dehydrogenase is expressed in the primary root while in the peroxidase it is evident in the shoot of the seedlings.

Abstract: The objective was to assess the early treatment effect of soybean seeds and pre-sowing with different combinations of chemicals on the establishment of plants and crop yield performance. The design was in randomized blocks in a 2x7 factorial arrangement, with two times for seed treatment and seven treatments (six chemical treatments and an untreated control). The treatments were: 1) fipronil + pyraclostrobin + thiophanate methyl; 2) imidacloprid + thiodicarb + carbendazin + thiram; 3) abamectin + thiamethoxam + fludioxonil + mefenoxam + thiabendazole; 4) carbendazin + thiram; 5) fludioxonil + mefenoxam + thiabendazole; 6) carboxin + thiram; and 7) untreated control (water only). The assessments were: seedling emergence, final stand, plant height and insertion of first pod, number of pods per plant, seeds per pod and per plant, thousand-seed weight and grain yield. Early treatment of soybean seeds (240 days prior to sowing) hinders the establishment of the crop, the thousand-seed weight and grain yield in relation to the pre-sowing treatment. Chemical treatments tested containing fungicides and insecticides associated favor the establishment of the crop, but do not alter the soybean yield performance.

Therefore, the aim of this study was verify the effect of fungicides and insecticides treatment in soybean seeds quality before and after storage. Seeds of NS 7494, NS 8693 and NS 7338 IPRO were utilized and analyses separately, through a factorial scheme 3x6, with three application moments: treated and assessed; treated, stored and assessed; stored, treated and assessed; and six combination of fungicides and insecticides: Cropstar(r) + Derosal Plus(r); Cropstar(r) + Maxim xl(r); Cruiser(r) + Derosal Plus(r); Cruiser(r)+ Maxim xl(r); Standak Top(r) and the control group. Germination, seedling emergence, accelerate aging, cold and health tests were performed. It was determined that the combination with Cruiser(r) doesn't affect the physiological quality of soybean seeds treated and assessed, and treated after two month of storage. Cropstar(r) + Derosal plus(r) keeps physiological quality of soybean seeds stored and treated for two months, while Standak top(r) has negative effect. The combination with Cropstar(r) damages the physiological quality of soybean seeds treat after two months of storage. The fungicide Derosal plus(r) improves the health quality of soybean seeds regardless treatment moment.
