Impacts of saline stress on the physiology of Saccharum complex genotypes
Simões, Welson Lima; Oliveira, Anderson Ramos de; Tardin, Flávio Dessaune; Oliveira, Cíntia Patrícia Martins de [UNESP]; Morais, Lizz Kezzy deMade available in DSpace on 2022-04-28T19:48:16Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-02-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Knowledge of the physiological mechanisms in saline environment may boost sugarcane breeding programmes targeting abiotic stresses. Our hypothesis is that the physiology of Saccharum genotypes responds differently under salt stress. T...
Selection indices to identify drought-tolerant grain sorghum cultivars
Menezes, Cícero Beserra de; Ticona-Benavente, César Augusto; Tardin, Flávio Dessaune; Cardoso, Mílton José; Bastos, Edson AlvesTwenty-five cultivars of grain sorghum [Sorghum bicolor (L.) Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block design with 3 replications. Eight drought tolerance indices including stability tolerance index, mean productivity (MP), geometric MP, harmonic mean, stress susc...
Utilização de cobertura comestível na conservação pós-colheita de minimilho min...
Queiroz, Valéria Aparecida Vieira; Queiroz, Luciano Rodrigues; Tardin, Flávio Dessaune; Pereira Filho, Israel Alexandre; Guedes, Estefânia de OliveiraMinimilhos obtidos das cultivares de milho Vivi, híbrido simples de endosperma doce em fase experimental, e AG 1051, híbrido duplo comercial, comum, foram revestidos com cobertura comestível de fécula de mandioca a 2 e 4% e armazenados a 5 ºC. Um tratamento controle, sem revestimento, foi utilizado nas mesmas condições. Foram realizadas análises físico-químicas a cada três dias, durante nove dias, e de perda de...
Genetic evaluation of grain sorghum hybrids in Brazilian environments using the...
Almeida Filho, Janeo Eustáquio de; Resende, Marcos Deon Vilela de; Silva, Fabyano Fonseca e; Granato, Ítalo Stefanine Correia; Tardin, Flávio DessauneWhen it comes to recommending sorghum (Sorghum bicolor) cultivars, it is essential to carry out a genetic evaluation of the agronomic traits of promising genotypes from several common environments where the crop is cultivated. This study consisted of a genetic evaluation of 52 experimental grain sorghum hybrids and eight commercial cultivars. Hybrids were evaluated in 19 experiments representing the most varied...
Comparação de métodos de correção de estande para estimar a produtividade de so...
Silva, Karla Jorge da; Menezes, Cicero Beserra de; Tardin, Flávio Dessaune; Souza, Vander Fillipe; Santos, Crislene VieiraA magnitude do erro experimental tem efeito direto no sucesso de experimentos, no melhoramento de plantas. Este trabalho objetivou verificar a interferência de métodos de correção de estande na produtividade de 25 híbridos de sorgo granífero, em sete ambientes. Os métodos avaliados foram: sem correção, regra de três, covariância de estande médio e de estande ideal, Zuber, Cruz, Vencovsky & Cruz e correção estra...
Use of sorghum straw (Sorghum bicolor) for second generation ethanol production...
Tavares, Gabriella Peterlini; Cardoso, Wilton Soares; Tardin, Flávio Dessaune; Queiroz, Paula Viana; Mota, Samuel Sampaio; Kasuya, Maria Catarina MegumiO artigo não contém resumo em português; Agronomic biomass yields of forage sorghum BRS 655 presented similar results to other energy crops, producing 9 to 12.6 tons/ha (dry mass) of sorghum straw. The objective of this study was to evaluate the lignocellulosic part of this cultivar in terms of its potential in the different unit processes in the production of cellulosic ethanol, measuring the effects of pretre...
Selection of lettuce genotypes for phosphorus uptaking efficiency - DOI: 10.402...
Cock, Wallace Rudeck Sthel; Tardin, Flávio Dessaune; Amaral Júnior, Antônio Teixeira do; Scapim, Carlos Alberto; Amaral, José Francisco Teixeira doNineteen late flowering lettuce genotypes from the UENF horticultural germoplasm bank were evaluated for phosphorus utilization efficiency under a 10 mg.dm-3 P level. A biometrical analysis of genetic parameters and genetic, phenotypic and environment correlations between shoot and root dry matter production, P content in roots and shoot Puptake, P-translocation and P utilization efficiency was undertaken. Gene...
