Deep tillage strategies in perennial crop installation: structural changes in c...
Azevedo, Raphael Passaglia; Corinto, Lara Mota; Peixoto, Devison Souza; Figueiredo, Tomás de; Silveira, Gustavo Cesar Dias; Peche, Pedro MaranhaTillage modifies soil structure, which can be demonstrated by changes in the soil’s physical properties, such as penetration resistance (PR) and soil electrical resistivity (ρ). The aim of this study was to evaluate the effect of deep tillage strategies on three morphogenetically contrasting soil classes in the establishment of perennial crops regarding geophysical and physical-hydric properties. The experiment...
Fruit quality and harvest point determination in white-fleshed dragon fruit
Rangel Junior, Ivan Marcos; Magalhães, Deniete Soares; Rodrigues, Filipe Almendagna; Pasqual, Moacir; Pio, Leila Aparecida SallesThe objective of this study was to evaluate the quality of white-fleshed dragon fruit (Hylocereus undatus) at harvest and postharvest to determine fruit quality and the feasibility of harvesting the fruits at different outer fruit color stages. The treatments consisted of four peel color stages – S1 (<25% red peel), S2 (25%-49% red peel), S3 (50% to 75% red peel) and S4 (>75% red peel) – and two evaluatio...
Simulating stress condition through compaction in banana plant cultivated In vitro
Almeida, Mirielle de Oliveira; Pio, Leila Aparecida Salles; Santos, Dalilhia Nazaré dos; Pasqual, Moacir; Luz, José Magno QueirozBanana cultivation is an agricultural activity practiced in different regions and constantly subjected to abiotic stresses that limit its productivity. To treat the effect of these stresses research can be undertake by simulating them in vitro since it limit the effect of the external factor in the experiment. Therefore, the objective of this study was to simulate the compaction in banana plant cultivated in vi...
Endoreduplication in floral structure, vegetative and fruits of red pitaya with...
Menezes, Thatiane Padilha; Pio, Leila Aparecida Salles; Ramos, José Darlan; Pasqual, Moacir; Setotaw, Tesfahum AlemuEndoreduplication is the change of cellular cycle that result DNA duplication without cell division and could result endopolyploid cells. This phenomenon is common in plants and animals and considered as evaluative strategy. Although endoreduplication reported in various plant species, the information about these phenomena in red pitaya is rare. Therefore, this work was done with the objective of studying the e...
Ultrastructural and cytochemical analysis of physic nut callus tissue in respon...
Santos, Dalilhia Nazaré dos; Nunes, Claudinéia Ferreira; Soares, Joyce Dória Rodrigues; Alves, Eduardo; Labory, Cláudia Regina Contijo; Pasqual, MoacirThis study aimed to induce callus formation in Jatropha curcas L. and to evaluate the ultrastructure and cytochemical behavior of the calli. Calluses were induced with 2,4-D, picloram-PIC, kinetin (Kin) and BAP: (1) control; (2) 4.52 µM 2,4-D; (3) 9.04 µM 2,4-D; (4) 4.14 µM PIC; (5) 8.28 µM PIC; (6) 4.52 µM 2,4-D + 2.32 µM KIN; (7) 9.04 µM 2,4-D + 4.64 µM KIN; (8) 4.14 µM PIC + 2.32 µM KIN; (9) 8.28 µM PIC + 4....
