1. Exploring the Herbicidal Potential of Achyranthes aspera Against Some Weeds
RESUMO A composição fitotóxica de Achyranthes aspera foi identificada através de cromatografia líquida de alta eficiência (CLAE), e o potencial herbicida da espécie foi investigado em relação a duas plantas daninhas de folhas estreitas (Phalaris minor Retz. e Avena fatua L.) e quatro de folhas largas (Lathyrus aphaca L., Vicia sativa L., Convolvolus

2. Morphological analysis and DNA methylation in Conyza bonariensis L. cronquist (Asteraceae) phenotypes
ABSTRACT The species Conyza bonariensis (L.) cause losses in agriculture due to their invasive capacity and resistance to herbicides like glyphosate. The species of this genus exhibit phenotypic plasticity, which complicates their identification and characterization. Thus, experiments were performed with 2 extreme C. bonariensis phenotypes (called broad leaf

3. Comparative study on morpho-anatomy of leaf, stem and root of Boerhaavia diffusa L. (Nyctaginaceae) and its adulterant plants
ABSTRACT Punarnava (Boerhaavia diffusa L.- Nyctaginaceae) is a promising drug to rejuvenate new cells in the body. It is well known in Ayurvedic medicine and locally called Tambadivasu. Superficially it is similar to other species of Boerhaavia and species of Trianthema and Sesuvium. Due to the minute morphological differences, the above plants are erroneous

4. Forage yield and nutritive value of Panicum maximum genotypes in the Brazilian savannah
The narrow genetic variability of grasslands and the incidence of new biotic and abiotic stresses have motivated the selection of new Panicum maximum genotypes for use as forage for beef cattle in the Brazilian savannah. This study aimed to evaluate forage yield and nutritive value of P. maximum genotypes including 14 accessions (PM30 to PM43), four intraspe

5. Ploidy levels in Citrus clementine affects leaf morphology, stomatal density and water content
The objective of the present study was to understand the relationship among leaf morphology, stomatal characteristics and water relations in triploids generated through anther culture and their counterpart diploid plant of C. clementina. Triploid plants possessed small and narrow leaves as compared to diploid plant as evident by less leaf length, leaf width

6. Densidade de semeadura e consÃrcio de braquiÃria e estilosantes visando à formaÃÃo de cobertura vegetal para a cultura da soja / Seeding density and consortium of brachiaria and stylosanthes aiming at vegetation cover to the soybean crop
The tillage efficiency is directly related to the management and choice of vegetation species prior to sowing the crop. In this context, this study examined the effect of brachiaria sowing densities (Brachiaria ruziziensis) (10; 15 and 20 kg ha-1), stylosanthes (Stylosanthes macrocephala and Stylosanthes capitata) (3; 4.5 e 6 kg ha-1) and consortium of these

7. Relationship between leaf stages and epistasis for resistance to Stagonospora nodorum in durum wheat
Ten varieties and eight generations (2F1, 2F2, 2B1 and 2B2) of durum wheat derived from two crosses were evaluated for resistance to natural infection by Stagonospora nodorum blotch (SNB) at the 2-3 and 6-7 leaf stages at two sites over two years. There were significant differences in the incidence of SNB between leaf stages in most of the wheat varieties, w

8. Assessing biophysical variable parameters of bean crop with hyperspectral measurements
Recently high spectral resolution sensors have been developed, which allow new and more advanced applications in agriculture. Motivated by the increasing importance of hyperspectral remote sensing data, the need for research is important to define optimal wavebands to estimate biophysical parameters of crop. The use of narrow band vegetation indices (VI) der

9. Morpho-anatomy of the leaf and stem of Eugenia pyriformis
Eugenia pyriformis Cambess., known as uvaia, is a species of Myrtaceae native to Brazil. Its leaves are used in folk medicine to treat gout because they possess the property of inhibiting xanthine oxidase, an enzyme involved in the conversion of xanthine into uric acid. The objective of this work was to study the leaf and stem morpho-anatomy of E. pyriformis

10. Morpho-anatomical study of the leaf and stem of pau-alecrim: Holocalyx balansae
Holocalyx balansae Micheli belongs to the Fabaceae family and is called pau-alecrim in Portuguese. In folk medicine, it is indicated to treat heart, hepatic and digestive upsets, as well as being considered anti-septic and diaphoretic. This work aimed to study the morpho-anatomy of the leaf and stem of this native medicinal species, in order to increase know

11. Genetic variability for disease resistance in Brazilian upland rice native germplasm.
Thirty nine rice genotypes were evaluated under dryland field conditions for resistance to leaf and neck blast, brown spot, leaf scald, narrow brown leaf spot and grain discolaration in 13 test sites during a three-year period. these include 17 land races, six traditional cultivars, 11 improved breeding lines and three exotic cultivars. There was a great div
