| O estudo objetivou relacionar a colorimetria do epicarpo dos frutos com o teor de bixina em sementes de urucum (Bixa orellana L.). A bixina é utilizada em diversos segmentos industriais, como farmacêutico, têxtil, de cosméticos e alimentício. Os frutos foram colhidos de árvores adultas e classificados visualmente em quatro estádios de maturação com base na coloração externa do epicarpo. Após a segregação visual, mensurou-se a coloração do fruto com um analisador digital de cores. A caracterização inicial se deu através da morfometria das sementes e da determinação do teor de água. O experimento seguiu delineamento inteiramente ao acaso, contendo quatro repetições. Frutos verdes e marrom-claro fechados apresentaram sementes com maior tamanho e teor de... |

| Morphometric measurements of woody species are fundamental to support and adapt silvicultural practices. The essay aimed to estimate interdimensional relationships in 6 years old pure stands of P. dubium and P. rigida trees planted in a 2 x 1 m spacing using diameter at breast height of 1.3 m (DBH) as an independent variable. The morphometric measurements included the total and the bole height, DBH, and projection of crown diameter with which we calculated crown length, crown proportion, crown projection area, slenderness rate, salience index, range index and crown formal interdimensional relations. Results indicated the possibility of using the DAP to estimate the crown length, slenderness rate (Ge) and salience index (Is) in P. rigida trees and crown... |

| The essay aimed to estimate fruit production of physic nut as a function of planting spacing and easily measured morphometric variables. Thirty 36 months old plants were randomly selected from a commercial plantation established on a 3 x 2 or 5 x 2 m spacing. Measurements per plant included height (ALT), number of primary branches (NG), average diameter of primary branches (DG), number of leaves (NFL), leaf area (AFL), number of fruits (NF) and fruit fresh biomass (MF). The largest values of NF , MF, AFL, NFL and DG were measured in plants from the 5 x 2 m. The estimation of number of fruits per plant (NF) from the two plant spacing can be obtained with plant height and leaf number using the model NF = -143,7611 + 91,32257*ALT - 0,14648*NFL + 0,0001*NFL2. |

| In this study, we sought to identify efficient enzymes for use in monitoring the deterioration and loss of germination of Balfourodendron riedelianum (Engler) Engler seeds. The research was conducted at the Laboratório de Tecnologia de Sementes e Mudas of the Universidade Estadual do Oeste do Paraná, Campus Marechal Cândido Rondon, Paraná State, Brazil. Seeds were harvested at three collection sites and later submitted for processing, drying, initial characterization and storage in airtight packaging under controlled and uncontrolled storage conditions and uncontrolled. Tests were conducted at 0, 120, 240, and 360 days using a germination test, germination speed index, accelerated ageing test and the activity of peroxidase, phenylalanine ammonia-lyase... |

| A rustificação objetiva expor as mudas a condições mais severas de manejo do que as adotadas na fase de crescimento a fim de torná-las mais tolerantes as adversidades do pós-plantio. Este trabalho objetivou avaliar o efeito da pulverização de concentrações de ácido jasmônico (AJ) em mudas de ipê roxo e guajuvira sobre a morfofisiologia e desempenho no campo. O experimento foi conduzido como delineamento inteiramente casualizado em viveiro e blocos casualizados a campo com mudas pulverizadas com 0,5, 1,0 e 1,5 µmol L-1 de ácido jasmônico mais a testumunha, sendo 20 mudas por tratamento, 5 repetições e 4 mudas por repetição. As análises a campo foram realizadas noventa dias após o plantio. Realizaram-se análises morfométricas, índice SPAD, relação altura da... |

| The study aimed to characterize fruits and seeds of Vitex montevidensis Cham during maturation. Fruits were harvested weekly according to maturation stage. Fruit morphological parameters included type, dehiscence, form, color, texture and pericarp consistency. Seed morphological parameters were type, color, dimensions, texture, form, structures and embryo characteristics. Results indicated that V. montevidensis fruit is nuculanio, indehiscent, globoso or ovoid, fleshy and with color varying according to maturation stages. The pyrenes are ovoids with four loculus with only one bearing a seed. The seed coat is beige with a papyraceae consistency when dry or membranaceae when hydrated. The hilum is heterochrom showing a dark brown color. |

| The increase in costs of selected and certified soybean seeds is evident in recent years. Knowing that farmers can use saved seeds, the aim of the study was to evaluate the physiological and sanitary quality of saved seeds produced in the first and the second crop in Western Paraná State, Brazil, compared to commercial seeds. The experiment was conducted at Seed Laboratory of the State University of West Paraná, with seeds of soybean cultivar Vmax RR (NK 7059RR), arranged in 5x3 factorial with four replications. For the first factor treatments refer to seed lots with different sources of production: two lots in the second crop of 2010 with and without seed treatment (ST), two lots of first crop of 2010/2011 with and without ST and one commercial lot of... |

| The Silvopastoral System (SPS) is understood as an interaction between trees, animals and pasture. The knowledge about the component action potentialities and limitations determines the system success or failure. The potentialities that can be highlighted are the heat reduction for animals and the improvement of the forage quality provided by the trees shadows. The reduction of pasture production at degraded systems is a limitation. The SPS is a sustainable option for family properties that produce meat and milk. The economical, social and cultural limitations are a problematic issue for the SPS adoption and it slows down the number of producers implementing it, specially the called family agriculture. The public policy deficiency to improve it, the lack... |

| The sucará also known as Gleditschia amorphoides is a important for the regeneration of riverine areas. Due to the presence of numbness imposed by the tegument, occurs late in seed germination, and obtaining the results, often does not correspond with the real force of the same. The tetrazolium method was used to assess the viabilidade of seed, especially because it is accurate, fast, low cost and easy to perform. This study aims to evaluate the seed vigor sucará from different sources through the tetrazolium test and seedling development. We used three seed origins, looking through the germination test, germination percentage, germination speed index, length of shoot and root mass of seedling. Parallel testing was held water content, weight of thousand... |
