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.

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.

Fulvic acid is an extraction product of humus which is very potential for supplement fertilizer and able to reduce either inorganic or organic fertilizer application. The information about fulvic acid application as supplement fertilizer on ginger in Indonesia is still limited. The objective of the study was lo find oul the efect of fulvic acid as supplement fertilizer on the growth, productivity and quality of young ginger. A green house trial was conducted from July lo November 1996. Five levels of fulvic acid concentration, 0, 2.5, 5, 7.5, and 10% were sprayed every week from 4 to 1 5 weeks ater planting (WAP). A randomized block design was used with five replicates. The results indicated that the growth of plant height and number of tiller of ginger increased rapidly al 8 WAP, then il became slowly from 12 lo 1 5 WAP Application 10% of fulvic acid was able to increase vegetative parts 99.6%, fresh and dry weight of rhizome 89 and 125% respectively, and starch content of rhizome 22.6%. To find oul of the optimal effect of fulvic acid on productivity and quality of ginger, a further research using higher level and application frequency of fulvic acid as an extract product from several humus types in Indonesia is needed.

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.

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.

Objective: This study aimed to assess the productivity and quality of a melon crop treated with fruit thinning and main stem pruning under field conditions. Experimental Design: The treatments comprised the amount of fruit thinning in the plant (one, two and without thinning) and the period of main stem pruning (35, 40, 45 and 50 days after transplanting - DAT). The crop was set up in a randomized block design factorial of type 3x4, with five replications. Location and Duration of the Study: The experiment carried out at the Center for Agrifood Science and Technology (CCTA) of the Federal University of Campina Grande (UFCG), Campus Pombal - PB, Brazil, from December 2016 to February 2017. Methodology: The Hopey King hybrid of the Cantaloupe group was cultivated at a spacing of 2.0 x 0.4 m. Results: The plants without thinning of fruits provided lower values ​​of leaf area and fruits of lower mass. However, due to their higher quantity per hectare, the crop total productivity was high. On the other hand, plants with fewer fruits had the highest values ​​of soluble solids, total and non-reducing soluble sugars. The leaf area, fruit mass, total productivity, and the concentration of reducing and non-reducing soluble sugars were higher when the plants were pruned at 35 DAT. Conclusion: The fruit thinning and main stem pruning affected the production and quality of melon fruits significantly. For more demanding markets, we recommend to treat the plants with one or two fruits and prune at 35 days after transplantation, aiming to enhance the quality variables.

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.

Summary Modifications in growing techniques can affect the yield and nutritional quality of various cultivated plants. Among them, the use of biostimulants is environmental friendly method of stimulating crop productivity, stress resistance, and affecting yield or chemical composition of the plants. The aim of the investigation was determining of the effect of biostimulant treatment on yield and its quality of carrot grown for summer harvest. The experiment was carried out in 2009-2011 in the experimental station of the University of Agriculture in Krakow, south Poland. Two experimental factors were taken into consideration: (1) cultivar: Nandrin F1 and Napoli F1 (2) dose of Aminoplant (foliar application): 1.5 and 3.0 dm3∙ha-1 and control (without Aminoplant). Total and marketable yield, root length, its diameter, leaf mass and leaf : root mass ratio were assessed. The dry matter, soluble sugar, carotenoids and nitrate ions contents were analyzed as main determinants of carrot nutritional quality. Aminoplant influenced not only carrot productivity, but mainly chemical composition of the roots. The present results also suggest that carrot reaction to biostimulant treatment was depended on a cultivar more than on environmental conditions in particular growing seasons. The significant effect of Aminoplant in a dose of 1.5 dm3∙ha-1 on the yield of roots and leaf rosette mass of ‘Nandrin F1’ appeared only in the first year of the experiment. Spraying with Aminoplant in a dose of 3.0 dm3∙ha-1 significantly increased the soluble sugars content in carrot roots of both cultivars but only in 2011. Dry matter content was also affected by biostimulant treatment mainly for ‘Napoli F1’, which showed the lowest dry matter content when sprayed with Aminoplant in a dose of 1.5 dm3∙ha-1. In 2010 control plants contained the greater amount of carotenoids, while in next year roots of plants treated with Aminoplant in a dose of 3.0 dm3∙ha-1 had more these compounds. The significant effect of Aminoplant on nitrates content in carrot roots was observed but were not repeatable in the experimental years, so different climatic conditions modified carrot reaction on biostimulant spraying.

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.

Aims: The objective was to determine the influence of the onion harvest time "Baia Periforme" on post-harvest quality of the bulbs during storage. Study Design: The experiment was conducted in a randomized block design with three treatments, six replicates with two bulbs each. Place and Duration of Study: Departamento de Fitotecnia, Universidade Federal de Viçosa, between June 2017 and July 2018. Methodology: Seedlings, 20 days old, were transplanted into 20 cm spacing between rows and 10 cm between plants. The bulbs were harvested 120 days after transplanting with manual tipping of the pseudo-stem (T1), with 50 (T2) or 75% (T3) of the bulbs popped. The soluble sugars (SS), non-reducing sugars (NRS), reducing sugars (RS), total soluble solids (TSS), titratable acidity of phenolic compounds and alinase activity was determined every 30 days for 90 days. Results: The content of SS, TSS, phenolic compounds and alinase activity increased in the onions of T2, resulting in more sweet and pungent bulbs due to the higher content of acidity and phenolic compounds. Conclusion: The post-harvest quality of onion bulbs "Baia Periforme" was maintained when they were harvested with 50% of bulbs popped.
