Differences in levels of lignin in the plant between conventional and transgenic cultivars RR has been reported by several authors, however, there are few studies evaluating the influence of spraying of glyphosate on the lignin in the plant and RR soybean seeds. The aim of this study was to evaluate the physiological quality of RR transgenic soybean seeds and the lignin contents of plants sprayed with the herbicide glyphosate. The assays were conducted both in greenhouse and field in the municipality of Lavras, MG, in the agricultural year 2007/08. The experiment was arranged in a splitplot design with four replicates, considering the treatments hand weeding and herbicide glyphosate as plots, and five RR soybean cultivars (BRS 245 RR, BRS 247 RR, Valiosa RR, Silvânia RR and Baliza RR) as splitplots. In the greenhouse, the cultivars tested were BRS 245 RR and Valiosa RR in a randomized block design with four replicates. The sprayings were carried out at stages V3, V7 and early R5 (3L/ha). The 1000 seed weight, mechanical injury, germination and germination velocity index, emergence velocity index, accelerated aging, electrical conductivity and water soaking seed test, lignin content in the seed coat, in the stem and legumes were determined. The spraying of glyphosate herbicide, in greenhouse and field, did not alter the physiological quality of seeds and the lignin contents in the plant.

Abstract: Some desiccation techniques for harvesting wheat may affect seed quality. The objective of this study was to evaluate the effect of different desiccant herbicides applied to the wheat crop and their effects on the production and seed quality. The experiment was conducted with cultivar COODETEC 150 (CD 150) in two sites in Palotina (Paraná state, Brazil) with a randomized block design consisting of 7 treatments (desiccation herbicides) and 4 replications. Desiccation was realized when 50% of the plants were in stage 80 with seeds in powdery or mass consistency. The variables analyzed were percentage of moisture content after harvest, Yield, hectoliter weight, mass of 100 seeds, vigor, germination, fresh mass of seedlings, dry mass of seedlings and root length. The herbicides carfentrazone-ethyl and clethodim were the ones that promoted greatest reduction in vigor. The herbicide paraquat caused reduction in seedling length. There was a reduction in the mass of 100 seeds for glufosinate-ammonium, clethodim, diquat and carfentrazone-ethyl. Glufosinate-ammonium, paraquat, glyphosate, clethodim and diquat caused reduction in yield. Desiccation of Cultivar CD 150 at stage 80 is not recommended, since plant Yield and physiological seed parameters were adversely affected by herbicides.

Plant lodging in wheat has been controlled through growth retardants. However, there is lack of information on the effect of these products on the physiological quality of seeds. The objective of this study was to evaluate the physiological quality of wheat seeds obtained under different rates and application times of three growth retardants. The trial was carried out in Viçosa-MG, from May to September 2005, in a factorial and hierarchical scheme, in randomized block design with four replications and a control treatment. The treatments consisted of 500, 1000 and 1500g ha-1 of chlormequat; 40, 80 and 120g ha-1 of paclobutrazol and 62.5, 125 and 187.5g ha-1 of trinexapac-ethyl applied at the 6 or 8 growth stage based on the scale of Feeks and Large, and a control treatment without growth retardant application. Leaf application of growth retardants as chlormequat, paclobutrazol and trinexapac-ethyl did not affect the germination and vigor of wheat seeds.

Main Components

This study aimed to relate the smallest set of variables that compose the quality of soybean seeds lot under study, as well as to evaluate the influence of four industrial seed treatments and their respective slurry volumes on the physiological potential. The experiment was carried out in a completely randomized block design with 4 replicates and 24 treatments. The chemical treatments were: control (T1), micronutrient + polymer + drying powder (T2), bioregulator + polymer + drying powder (T3) and micronutrient + bioregulator + polymer + drying powder (T4). The seeds were stored for periods of 0, 15, 30, 45, 60 and 90 days and were subsequently evaluated for their physiological potential. In each storage period, the variable germination, first count, accelerated aging, emergence speed index, final emergence in the sand substrate, aerial part length, root length and total seedling length were evaluated. The main components of the standard germination test and first count were the ones that most contributed to explaining the variability of the original data. Increasing the volume of the slurry in the industrial seed treatment reduces the physiological quality of soybean seeds during storage.

The objective of this study was to evaluate the yield and physiological quality of bean seeds in two agricultural crops, and the chemical composition of seedlings submitted to adverse temperatures during germination. For the field experiment, a randomized block design was used, using five genotypes, BRS Embaixador, IPR Tuiuiú, Guabiju, Carioquinha and Mouro, arranged in four replicates. The experimental units were composed of five lines with five meters in length, where 25 plants were randomly collected per experimental unit to measure the characters of interest. For laboratory testing the seeds produced were submitted to three temperatures (15, 25 and 35°C) during germination under controlled conditions. The evaluated characters were: grain yield, mass of a thousand seeds, germination, first germination count, starch content, soluble sugar, soluble protein and total amino acids. The data were submitted to analysis of variance and later compared by the Tukey test. Yield per plant revealed changes between the agricultural crops, as well as among the genotypes tested. Germination and the first germination count revealed higher magnitudes in seeds produced by BRS Embaixador, IPR Tuiuiu and Carioquinha genotypes. For all genotypes, protein and amino acid levels were higher in seedlings submitted to lower temperatures. The levels of starch and total soluble sugars were higher in seedlings produced at 35°C. Yield, seed physiological quality and chemical composition of seedlings are influenced by the crop and genotypes tested.

Abstract: The objective of this experiment was to evaluate responses of soybean cultivars seeds (with different levels of lignin) considering harvest postponement under the incidence of water and the effect of storage. The experiment was conducted in Iraí de Minas, Brazil using a randomized block design with three replications under a 5 x 3 x 3 factorial arrangement, with five soybean cultivars (NK 7059 RR, SYN 1163 RR, SYN 9070 RR, AS 7307 RR and SYN 1283 RR), three harvesting periods (R8, R8 + one rain simulation in the pre-harvesting period and R8 + two simulations in the pre-harvesting period) under three storage times (0, 90 and 180 days). Seeds were evaluated for their chemical composition (lignin contents), the percentage of moisture damage using the tetrazolium test and physiological quality (germination, accelerated aging, conductivity test, seedling emergence and emergence index). Cultivar AS 7307 RR had the highest lignin content in the integument, the lowest percentage of damage by moisture and the highest physiological quality. Cultivars NK 7059 RR and SYN 1163 RR had the lowest lignin contents in the integument and the highest moisture damage. Electrical conductivity increased after storing all cultivars.

Physiological Quality

Barley (Hordeum vulgare L.) is considered one of the most important cereals, such as maize, rice and wheat, due to its multiplicity of usage, as much for human consumption as for feed. The Nitrogen is one of the main nutrients that influences the quality and productivity of barley seeds because it participates in numerous metabolic routes. It is a limiting factor of the production, the lack or the excess can bring consequence to the culture. In this manner, the present study aims to evaluate the influence of different nitrogen doses on the physiologic quality and biochemical characters of brewing barley seeds produced in two growing environments. The experiment was conducted in the 2017 crop season, in a randomized block design, organized in a factorial scheme, being 2 cultivation environment × 2 brewing barley cultivars × 4 nitrogen doses, disposed in four replicates. The physiological quality of the seeds was evaluated by germination, first counting of germination, accelerated aging, field emergence, shoot and root length, dry mass of shoot and root of seedlings, electrical conductivity (3, 6 and 24 hours) and isoenzymes. The growing environment promotes differences in the barley seeds physiologic quality. The nitrogen fertilizing, at dose of 120 kg ha-1, results in superiority in the physiologic quality of seeds. The cultivar BRS Cauê in both environments presented higher vigor. The nitrogen fertilizing alters the isoenzymatic expression of barley seedlings, creating variation in the bands intensity, at different nitrogen doses.
