Resumo: | Zucchini is traditionally used in human consumption, however, the scarcity of information, especially about fertilization and the physiological aspects of this crop, constitutes a major obstacle its cultivation and commercialization. The objective was evaluate the chlorophyll content and gas exchange under cattle bio-fertilization and different sources of nitrogen. The work was carried a randomized block experimental design was used in a factorial scheme 5 x 3 + 1 composed of five cattle bio-fertilizer concentrations, three sources of nitrogen and an additional treatment without nitrogen. The levels of chlorophyll a, b and total, liquid photosynthesis, transpiration, internal CO2 concentration, stomatal conductance, instantaneous water use efficiency, and instantaneous carboxylation efficiency were evaluated. The studied variables were influenced by the interaction between the concentrations of the cattle bio-fertilizer and the nitrogen sources, except for the chlorophyll b content and the instantaneous water use efficiency, which responded only to the nitrogen sources. Ammonium sulfate and urea increased increase the physiological variables evaluated. The combination of ammonium sulfate with bio-fertilizer promoted an increase in chlorophyll a, total chlorophyll, liquid photosynthesis, transpiration, internal carbon concentration, stomatal conductance, and instantaneous carboxylation efficiency. The cattle bio-fertilizer in the soil without nitrogen did not increase the physiological variables evaluated. |

El objetivo fue evaluar el contenido de clorofilas y el intercambio de gases en calabacines fertilizados con biofertilizante bovino y diferentes fuentes de nitrógeno. El trabajo se realizó en un diseño de bloques al azar en un esquema factorial 5 x 3 + 1, con cinco prácticas de biofertilizante bovino, tres fuentes de nitrógeno y un tratamiento adicional sin nitrógeno. Las variables analizadas fueron niveles de clorofila a, by total, fotosíntesis líquida, transpiración, concentración interna de CO2, conductancia estomática, eficiencia de uso instantáneo de agua y eficiencia de carboxilación instantánea. A partir de los resultados, las variables estudiadas fueron influenciadas por la interacción entre las fuentes de biofertilizante bovino y las fuentes de nitrógeno, con excepción del contenido de clorofila b y la eficiencia instantánea en el uso del agua que respondía solo a las fuentes de nitrógeno. El sulfato de amonio y la urea estimularon la formación de clorofila by la eficiencia instantánea en el uso del agua. Una combinación de sulfato de amonio con biofertilizante proporcionó incrementos en la clorofila a, clorofila total, fotosíntesis líquida, transpiración, concentración de carbono interno, conductancia estomática y eficiencia de carboxilación instantánea. El biofertilizante bovino en suelo sin nitrógeno no incrementó las variables fisiológicas evaluadas.A abobrinha é utilizada tradicionalmente na alimentação da população, no entanto, a escassez de informações, sobretudo para a adubação e os aspectos fisiológicos da cultura, constitui-se em grande entrave para melhoria no cultivo e comercialização. Objetivou-se avaliar os teores de clorofilas e trocas gasosas em abobrinha adubada com biofertilizante bovino e diferentes fontes de nitrogênio. O trabalho foi realizado em delineamento experimental de blocos casualizados em esquema fatorial 5 x 3 + 1. Sendo, cinco concentrações de biofertilizante bovino, três fontes de nitrogênio e um tratamento adicional sem nitrogênio. As variáveis analisadas foram teores de clorofila a, b e total, fotossíntese líquida, transpiração, concentração interna de CO2, condutância estomática, eficiência instantânea no uso da água e eficiência instantânea de carboxilação. Pelos resultados, as variáveis estudadas foram influenciadas pela interação entre as concentrações de biofertilizante bovino e as fontes de nitrogênio, com exceção do teor de clorofila b e da eficiência instantânea no uso da água que responderam apenas às fontes de nitrogênio. O sulfato de amônio e a ureia estimularam a formação de clorofila b e a eficiência instantânea no uso da água. A combinação do sulfato de amônio com biofertilizante proporcionou aumentos na clorofila a, clorofila total, fotossíntese líquida, transpiração, concentração interna de carbono, condutância estomática e eficiência instantânea de carboxilação. O biofertilizante bovino no solo sem nitrogênio não proporcionou aumento nas variáveis fisiológicas avaliadas.Research, Society and Development2020-12-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/810710.33448/rsd-v9i11.8107Research, Society and Development; Vol. 9 No. 11; e8099118107Research, Society and Development; Vol. 9 Núm. 11; e8099118107Research, Society and Development; v. 9 n. 11; e80991181072525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/8107/9613Copyright (c) 2020 Damiana Ferreira da Silva Dantas ; Ronaldo Nascimento; Ademar Pereira Oliveira ; Lourival Ferreira Cavalcante; Naysa Flávia Ferreira Nascimento ; Tony Andreson Guedes Dantashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDantas , Damiana Ferreira da Silva Nascimento, RonaldoOliveira , Ademar Pereira Cavalcante, Lourival Ferreira Nascimento , Naysa Flávia Ferreira Dantas, Tony Andreson Guedes 2020-12-10T23:37:57Zoai:ojs.pkp.sfu.ca:article/8107Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:39.544229Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
