MORPHOLOGY OF TOMATO PLANTS UNDER NEMATODE ATTACK AND SALICYLIC ACID APPLICATION
Figueiredo, Francisco Romário Andrade; Ribeiro, João Everthon da Silva; Silva, Toshik Iarley da; Nóbrega, Jackson Silva; Melo, Marlenildo FerreiraRoot-knot nematodes are the main soil-dwelling phytopathogens that cause severe damages to plants, especially tomato plants. Exogenous application of salicylic acid (SA) can mitigate such pathogenicity. This work aimed to evaluate the growth of tomato plants submitted to Meloidogyne javanica population densities (PD) and application of SA. The experiment was a randomized block design, in an incomplete factorial...
FITOMASSA E CRESCIMENTO DE MANJERICÃO ROXO IRRIGADO COM ÁGUA SALINA SOB ADUBAÇÃ...
Nóbrega, Jackson Silva; Silva, Toshik Iarley da; Bezerra, Ana Carolina; da Silva Ribeiro, João Everthon; da Silva, Antônio VeimarBasil is a species with high exploitation potential. However, its production in semiarid regions is compromised due to the salts contained in the soil and in the water used in irrigation, requiring the adoption of techniques that increase the tolerance of plants to salinity, such as nitrogen fertilization. Thus, this study aimed to evaluate the effect of leaf nitrogen fertilization on growth and phytomass alloc...
Water salinity and salicylic acid on tomato plants growth
Nóbrega, Jackson Silva; Figueiredo, Francisco Romário Andrade; Silva, Toshik Iarley da; Ribeiro, João Everthon da Silva; Fátima, Reynaldo Teodoro deA tomate é uma das hortaliças mais importantes do mercado brasileiro. A produção dessa hortaliça pode ser limitada pelo excesso de sais na água utilizada para irrigação. O uso de fitormônios, como o ácido salicílico (AS), é utilizado para minimizar os efeitos negativos do excesso de sais nas plantas. O objetivo deste trabalho foi avaliar o efeito atenuante do ácido salicílico no crescimento de tomateiro irrigad...
Photosynthesis of Physalis peruviana under different densities of photons and s...
Figueiredo, Francisco Romário Andrade; Ribeiro, João Everthon da Silva; Nóbrega, Jackson Silva; Celedônio, Wilma Freitas; Fátima, Reynaldo Teodoro dePhysalis peruviana L. is a solanacea that has been gaining prominence due to its fruits presenting good acceptance in the national and international market. However, several abiotic factors, such as salinity, can cause physiological disturbances in plants, and these changes may be of greater or lesser intent according to species. Therefore, the objective of the present work was to evaluate the physiological beh...
Physiological changes in Solanum lycopersicum L. in the presence of root-knot n...
Figueiredo, Francisco Romário Andrade; Nóbrega, Jackson Silva; Ribeiro, João Everthon da Silva; Silva, Toshik Iarley da; Albuquerque, Manoel Bandeira deNematodes of the genus Meloidogyne spp. are one of the tomato culture’s main pathogens. According to their soil infestation level, physiological changes may occur. Consequently, it is extremely important to employ given products to minimize their effect. A feasible option is the salicylic acid, a phytohormone that can induce into resistance due to its ability to increase the production level of some pathogenici...
Effects of irrigation water salinity and salicylic acid on germination and vigo...
Nóbrega, Jackson Silva; Bruno, Riselane de Lucena Alcântara; Figueiredo, Francisco Romário Andrade; Silva, Toshik Iarley da; Silva, Ronimeire Torres daSalinity is one of the factors that negatively impact plant growth and productivity; therefore, it is necessary to seek solutions that help mitigate the degenerative action of saline stress on crops. The objective of this study was to evaluate the effects of salicylic acid (SA) on the germination and vigor of Mesosphaerum suaveolens (L.) Kuntze seeds subjected to salinity. The experiment was carried out using a...
Growth and chlorophyll indices in seedlings of Calotropis procera (Aiton) W. T....
Andrade Figueiredo, Francisco Romário; da Silva Ribeiro, João Everthon; Santos Coêlho, Ester dos; Nóbrega, Jackson SilvaSeveral abiotic factors may influence the growth and development of forest species. Among these, luminosity is one of the most important, because it affects plant physiological processes and control their metabolism. The objective of this study was to evaluate the effect of different shading levels under growth and chlorophyll indices on Calotropis procera plants. The experiment was conducted in a greenhouse in...
Temperatures and substrates for germination and vigor of Erythroxylum pauferren...
Ribeiro, João Everthon da Silva; Leite, Arliston Pereira; Nóbrega, Jackson Silva; Alves, Edna Ursulino; Bruno, Riselane de Lucena AlcântaraErythroxylum pauferrense is an endemic understory plant species of the Northeast Region of Brazil. The species is of great importance to the region and so ecophysiological studies are needed for its preservation. The objective of the present study was to determine the best substrates and temperatures for testing germination and seed vigor of E. pauferrense. An experiment was performed comprising a completely ra...
Qualidade fisiológica de sementes de melão pepino sob salinidade crescente da á...
Nóbrega, Jackson Silva; Figueiredo, Francisco Romário Andrade; Nascimento, Rodrigo Garcia Silva; Bruno, Riselane de Lucena AlcântaraO melão pepino Cucumis melo var.Cantalupensis Naud é uma espécie crioula que apresenta alta adaptabilidade às condições edafoclimáticas do semiárido nordestino, servindo como fonte de renda e alimentar. Nesse contexto, o objetivo do trabalho foi avaliar a qualidade fisiológica de sementes de melão pepino submetidas à irrigação com águas salinas de 0,012, 2, 4, 6 e 8 dS m-1, na percentagem de germinação, primeir...
Produção, aspectos nutricionais e fisiológicos de alface sob adubação foliar co...
Silva, Débora Samara Oliveira e; Nóbrega, Jackson Silva; Rocha, Railene Hérica Carlos; Araújo, Josinaldo Lopes; Guedes, Wellinghton AlvesObjetivou-se avaliar a influência de concentrações do fertilizante orgânico a base de Spirulina platensis sobre a produção, crescimento, teores de N, P, K e sódio e sobre as trocas gasosas de alface cv. Elba em condições de campo. Utilizou-se o delineamento de blocos ao acaso, com seis tratamentos, constituídos das concentrações do fertilizante (0; 1,5; 3,0; 4,5; 6,0 e 7,5%) com seis repetições. No ponto de col...
