Resumo: | The term senescence is used mainly for plants to define genetically programmed degenerative physiological changes. Leaf senescence is the result of internal and external environmental signals as well as information on leaf age. Christella hispidula (Decne.) Holttum is a species of fern characterized by its adaptation ease and consequent broad occupation of different environments. The aim of the present study was to investigate the phenology of C. hispidula in a remnant of the Atlantic Forest to gain knowledge on abiotic and biotic factors associated with leaf senescence throughout the seasons. Multiple regression analysis was used to estimate correlations between leaf senescence and both the occurrence of herbivory and presence of sori in the population studied. Positive correlations were found with these two variables. Senescence increased significantly with each new sign of herbivory on the plant (p = 0.46) and with the emergence of sori on the plant (p = 0.02). The multiple coefficients of determination (R2= 0.47) explained approximately 47% of the dependence of senescence on herbivory and sori. The findings reveal that the seasons exert an influence on leaf senescence in C. hispidula. |

La senescencia de la hoja es el resultado de señales ambientales internas y externas, así como información sobre la edad de la hoja. Christella hispidula (Decne.) Holttum es una especie de helecho que se caracteriza por su facilidad de adaptación y consecuentemente una amplia ocupación de diferentes ambientes. El objetivo del presente estudio fue investigar la fenología de C. hispidula en un remanente de Mata Atlántica para conocer los factores abióticos y bióticos asociados con la senescencia de las hojas a lo largo de las estaciones. Se utilizó un análisis de regresión múltiple para estimar las correlaciones entre la senescencia de las hojas y la ocurrencia de herbivoría y la presencia de soros en la población estudiada. Se encontraron correlaciones positivas con estas dos variables. La senescencia aumentó significativamente con cada nuevo signo de herbivoría en la planta (p = 0,46) y con la aparición de soros en la planta (p = 0,02). El coeficiente de determinación múltiple (R2 = 0,47) explicó aproximadamente el 47% de la dependencia de la senescencia de la herbivoría y los soros.

A senescência foliar é resultado de sinais ambientais internos e externos em informações sobre a idade foliar. Christella hispidula (Decne.) Holttum é uma espécie caracterizada por sua facilidade de adaptação e consequente ampla ocupação de suas populações. O objetivo geral deste trabalho foi entender a fenologia da C. hispidula em um remanescente de Floresta Atlântica, buscando compreender suas relações abióticas e bióticas a partir da senescência foliar ao longo das estações sazonais. Para estimar a correlação entre a senescência foliar e o valor os dados de herbivoria e soros na população estudada, foi realizado o teste de regressão múltipla. Assim, foi observada a ocorrência da correlação positiva entre a senescência foliar e as duas variáveis supracitadas, onde a cada novo sinal de herbivoria na planta a senescência aumenta (p=0.46), bem como, para surgimento de soros na planta, a senescência foliar tem aumento estatisticamente significativo (p=0.02). O coeficiente de determinação múltipla (R2=0.47) explica aproximadamente 47% da dependência da senescência diante da herbivoria e soros. Assim, conclui-se que as estações influenciam na senescência foliar em C. hispidula.Research, Society and Development2022-12-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3822110.33448/rsd-v11i16.38221Research, Society and Development; Vol. 11 No. 16; e500111638221Research, Society and Development; Vol. 11 Núm. 16; e500111638221Research, Society and Development; v. 11 n. 16; e5001116382212525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/38221/31884Copyright (c) 2022 Naara Ferraz dos Santos; Sergio Romero da Silva Xavier; Nyedja Fialho Morais Barbosahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSantos, Naara Ferraz dos Xavier, Sergio Romero da Silva Barbosa, Nyedja Fialho Morais 2022-12-18T18:26:42Zoai:ojs.pkp.sfu.ca:article/38221Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:52:03.209387Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
