Nutritional status of ‘BRS Rubimel’ peach plants in the nursery as a function o...
Menegatti, Renata; Souza, Aline das Graças; Bianchi, Valmor JoãoImprovements in the traditional production system of peach seedlings, with a focus on the use of selected rootstocks, tend to minimize some of the problems experienced with this crop in the south of Brazil, such as the scarcity of vigorous nursery plants and the lack of a genetic identity for commercial rootstocks. The aim of this study was to investigate the different patterns of nutrient absorption and alloca...
Seedling quality of Agonandra brasiliensis in response to different Osmocote® d...
Mota, Eduardo Rodrigues; Smiderle, Oscar José; Dionisio, Luiz Fernandes Silva; Souza, Aline das Graças; Montenegro, Raiovane Araújo; Schwartz, GustavoThe objective of this work was to evaluate seedlings quality of the tree species Agonandra brasiliensis under different doses of the controlled release fertilizer (CRF) Osmocote® and recipient volumes. The experiment was set up in a factorial design for two recipient volumes (1.8 L and 2.2 L) and five CRF doses (0.0; 0.5; 1.0; 2.0; and 3.0 g L-1 of substrate). Four repetitions of one plant each were used. After...
Gas exchanges and chlorophyll content in green pepper plants under bio-fertiliz...
Leal, Ygor Henrique; Jardelino Dias, Thiago; Souza, Aline das Graças; Bezerra, Ana Carolina; Soares Rodrigues, Lucas; Bandeira de Albuquerque, ManoelThis study aimed to determine the gas exchange and the chlorophyll content of green pepper plants under doses and times of application of bio-fertilizers based on manure and enriched organic compost. Two experiments were carried out simultaneously with applications of bio-fertilizers prepared from manure and enriched organic compost, one using cattle manure (CBF) and the other sheep manure (SBF). For these, fou...
The Effect of packaging and storage conditions on the physiological quality of ...
Smiderle, Oscar José; Nascimento, Cassia Rejane do; Chagas, Edvan Alves; Chagas, Pollyana Cardoso; Souza, Aline das GraçasThe study aimed to verify the physiological quality of seeds of Myrciaria dubia, stored for 300 days in different conditions and packaging, using tests of electrical conductivity and seedling vigour. The seeds were classified into three weight classes (small, medium and large). Small seeds were considered those with a weight of less than 0.84 g, medium seeds with a weight between 0.86 g and 1.20 g, and large se...
Macronutrient uptake, transport and use efficiency in seedlings of Pochota fend...
Souza, Aline das Graças; Smiderle, Oscar José; Menegatti, Renata Diane; Dias, Thiago JardelinoSeedlings produced in containers can be influenced by the materials used in the substrate, which affects the robustness of the plants and, indirectly, the time required for transplanting and for the plants to become established in the field. The aim of this study was to determine the chemical properties of different materials and on the absorption of macronutrients in Pochota fendleri seedlings (cedro-doce). Th...
DISTRIBUIÇÃO ESPACIAL DA BROCA-DO-ESTIPE-DO-COQUEIRO
Silva, Emanuel Júnior Pereira da; Souza, Ademária Aparecida de; Oliveira, Anderson Castro Soares de; Neves, Jhonatan David Santos dasO objetivo desta pesquisa foi estudar a distribuição espacial de Rhinostomus barbirostris (Coleoptera: Curculionidae) (Fabricius, 1775) em coqueiro (Cocos nucifera L.). Foram realizadas 10 amostragens quinzenalmente do número de machos, fêmeas e total (macho + fêmea), de R. barbirostris em armadilhas demarcada com uma tela de náilon envoltas as palmeiras com sintoma característico do ataque dessa praga, totaliz...
The effect of rootstocks on the vigor, yield, and fruit quality of ‘Maciel’ pea...
Almeida, Cintia Borges; Souza, Aline das Graças; Argenta, Josiane Carla; Fachinello, Jose Carlos; Bianchi, Valmor JoãoThis study was conducted aiming to evaluate the effect of rootstocks in plant vigor, yield, and fruit quality of ‘Maciel’ peach trees growing in a 7-8-year-old orchard in the municipality of Pelotas, Rio Grande do Sul state, Brazil. The experiment was performed with plants of the ‘Maciel’ cultivar grafted on the following eight Prunus persica rootstocks: ‘Capdeboscq’, ‘Aldrighi’, ‘Tsukuba 1’, ‘Okinawa clone 1’...
Growth and nutritional status and quality of Khaya senegalensis seedlings
Smiderle, Oscar José; Souza, Aline das Graças; Chagas, Edvan Alves; Alves, Marcia de Souza; Fagundes, Paulo Renato de OliveiraDue to the shortage of information on both mineral fertilizer and organic substrate in Khaya senegalensis, it was proposed in the current study to verify the potential of the use or not of addition of nutrient solution in the production of high quality seedlings of K. senegalensis as well as to obtain the total accumulation of macro and micronutrients in the seedlings. The experimental design was completely ran...
Behavior of peach and mume rootstocks to the nematode Meloidogyne enterolobii
Souza, Aline das Graças; Chalfun, Nilton Nagib Jorge; Musser, Rosimar dos Santos; Fachinello, José Carlos; Campos, Vicente PaulaThe purpose of this study was to evaluate the response of one mume rootstock and five peach rootstocks (Capdeboscq, Aldrighi, Tsukuba, Flordaguard, Okinawa) to the nematode Meloidogyne enterolobii. Plants averaging 12 cm in height were transferred to a greenhouse. Genotypes were individually inoculated with a suspension of 104 eggs of M. enterolobii. The study was carried out in a completely randomized design...
Tipos de adubação e épocas de avaliação na sanidade e viabilidade de sementes d...
Lima, Juliana Maria Espíndola; Smiderle, Oscar José; Alves, José Maria Arcanjo; Chagas, Edvan Alves; Souza, Aline das GraçasAs sementes de soja-hortaliça, mesma espécie da soja comum, possuem características especiais, tais como: sabor, textura diferenciada para utilização na alimentação humana como hortaliça, quando as sementes estão imaturas, no estádio R6. Objetivou-se com este trabalho avaliar o efeito de cinco tipos de adubação e duas épocas de avaliação na sanidade e a viabilidade de sementes de soja-hortaliça, cultivar BRS 25...
