Mass and Nutrient Content of Beans and Husks of Coffea racemosa and Coffea zang...
Alberto, Niquisse José; Silva, Larícia Olária Emerick; Almeida, Rafael Nunes de; Rodrigues, Weverton Pereira; Zandamela, Augusto JossiasCoffea racemosa and C. zanguebariae show promising characteristics for cultivation under stress conditions. However, their potential for breeding programs requires further characterization, especially regarding fruit attributes. This study aimed to characterize the bean/husk ratio and the nutrient content in bean and husks from 22 accessions of Coffea racemosa and another 22 of C. zanguebariae cultivated in Moz...
Comparison of selection traits for effective popcorn (Zea mays L. var. Everta) ...
Kamphorst, Samuel Henrique; Amaral Júnior, António Teixeira do; Lima, Valter Jário; Santos, Pedro Henrique Araújo Diniz; Rodrigues, Weverton PereiraClimate change is expected to intensify water restriction to crops, impacting on the yield potential of crops such as popcorn. This work aimed to evaluate the performance of 10 field cultivated popcorn inbred lines during two growing seasons, under well-watered (WW) and water stressed (WS) (ysoil≥ −1.5 MPa) conditions. Water stress was applied by withholding irrigation in the phenological phase of male pre-anth...
Photosynthetic capacity, leaf respiration and growth in two papaya (Carica papa...
Paixão, Jessica Sousa; Silva, Jefferson Rangel; Ruas, Katherine Fraga; Rodrigues, Weverton Pereira; Machado Filho, José AltinoGolden genotype of papaya (Carica papaya), named for its yellowish leaves, produces fruits very much appreciated by consumers worldwide. However, its growth and yield are considerably lower than those of other genotypes, such as ‘Sunrise Solo’, which has intensely green leaves. We undertook an investigation with the goal of evaluating key physiological traits that can affect biomass accumulation of both Golden ...
Influence of tannery wastewater sludge doses on biometric and chlorophyll fluor...
Berilli, Sávio Silva; Zooca, Alan Alvino Falcão; Ferraz, Tiago Massi; Figueiredo, Fábio Afonso Mazei Moura de Assis; Rodrigues, Weverton PereiraTannery wastewater sludge is an industrial residue that can be used in the pure form or associated to other residues, such as byproduct production from cultivated plants. The objective of the present study was to assess substrate composition for producing conilon coffee stem cuttings, varying increasing tannery wastewater sludge doses. A randomized block design was used with four treatments, three increasing do...
Efect of draft an Meloidogyne exigua (Nemata) infestation on coffee's root grow...
Barbosa, Dimmy Herllen Silveira Gomes; Vieira, Henrique Duarte; Rodrigues, Weverton Pereira; Filho, Júlio Cézar Rodrigues; Barroso, Deborah GuerraThe State of Rio de Janeiro was once the main coffee producer in Brazil, but the infestation of nematodes (Meloidogyne exigua) has caused the production decline since the nineteenth century. The use of resistant cultivars is the main measure nematode control, and the resistant genotypes can be used both grafted or not. Coffea canephora is nematode resistant and it has a more developed root system compared to C....
