| Phalaris minor Retz. (“alpistillo”) es considerada como una maleza importante en el cultivo de trigo en la región del Bajío Mexicano, que ha desarrollado resistencia a herbicidas inhibidores de la Acetil Coenzima A Carboxilasa (ACCasa). Se ha consignado que más de la mitad de la población de Phalaris spp. comúnmente escapa del control manual a causa de la similitud morfológica con el cultivo de trigo. El objetivo de la presente investigación fue determinar si existen diferencias morfológicas y fenológicas entre biotipos resistentes y susceptible de P. minor a los herbicidas, y cultivares de trigo. Se realizaron experimentos en Montecillo, México en condición de no competencia. Se emplearon cuatro biotipos de alpistillo resistentes y uno susceptible,... |

| ABSTRACT The Registro Nacional de Cultivares [RNC (National Register of Cultivars)] and the Serviço Nacional de Proteção de Cultivares [SNPC (National Service for Cultivar Protection)] were established by the Ministry of Agriculture, Livestock and Food Supply (MAPA) in 1997. The registration of a cultivar in the RNC allows the production, processing and commercialization of seeds in the country. The right of commercial exploitation, assured by the protection of a cultivar in the SNPC, allows the allocation of resources to public and private breeding programs, and the subsequent launching of new cultivars. The authors’ experience with the theme and its relevance to the public and private sectors provided the base for this article, thus sharing the elements... |

| Abstract Due to the lack of studies comparing Syzygium malaccensis(L) Meer e Perry, Syzygium aqueum Burm.f. and Syzygium jambos (L) Alston Syzygium in relation to the botanical genus Sygygium regarding the physical characteristics, the present research was conducted, aiming at biometrically characterizing each of the three species, as well as comparing them. The fruits were collected from the São Paulo State University (Unesp), School of Agricultural and Veterinarian Sciences, Jaboticabal. Syzygium plants were used for the evaluation of: fruit and seed masses (g); width and length of leaves (cm) and of seeds (cm); percentage of fruit pulp; length of leaf petiole (cm); and leaf area (cm2). Fifty fruits, leaves and seeds of each species were used, with 5... |

| ABSTRACT Cassava is an important culture in Brazil and in the North of the country, and soft root rot has affected root production. The aim of this work was to identify root morphoanatomic and histochemical characters associated with root rot resistance. In areas with no occurrence of the disease, nine cassava genotypes were tested, four of which were resistant, and five were susceptible to root rot. Root harvest was carried out twelve months after sowing, and thickness of suber, suber and cortex, and secondary xylem were measured. Moreover, texture, suber cell layers, lignin content, and lignin monomers content of the portion suber and cortex were analyzed. Also, histochemical tests and scanning electron microscopy (SEM) analyses of the roots were... |

| The powdery mildew caused by Oidium spp. is an important disease for several crops of the Cucurbitaceae family. Although the teleomorphs, Podosphaera xanthii and Golovinomyces cichoracearum, currently have already been described as the causal agents of powdery mildew in Brazil, only P. xanthii is considered the main causal agent of powdery mildew field epidemics. The objective of this work was to identify and determine the prevalence of the species causing powdery mildew in cucumber (Cucumis sativus) and melon (Cucumis melo var. reticulatus) grown in greenhouses in the State of Paraná in Brazil. The morphological traits of the conidial stages, such as the presence of fibrosin bodies and a germinative tube, were used to identify the species. Leaves... |

| ABSTRACT Peanut or groundnut (Arachis hypogaea L.) is a globally important oilseed crop, with important nutritional qualities, and a rich source of amino acids and protein. Another 80 species have been described in the genus Arachis, 64 of which are found in Brazil, and even though their morphology and agronomic traits remain largely unknown, they have been cultivated for forage and for landscaping and have great potential for breeding with cultivated peanut. Thus, the morphological characterization of wild Arachis species is essential for their conservation and use. In this study, we present a morphological and agronomic characterization of 29 diploid accessions of eleven wild Arachis species and one of the tetraploid A. monticola (section Arachis) with A... |
