Resumo: The objective of this work was to evaluate the phenology of Calotropis procera accessions based on morphophysiological characteristics. Seeds of 70 C. procera accessions were collected between October 2015 and January 2016 in areas where the species naturally occurs in Northeastern Brazil. These accessions make up the current germplasm collection of the National Institute of the Semi-arid (INSA). The experiment was conducted in a greenhouse at INSA, in Campina Grande - PB, from January to September in 2016. The plants were cultivated in plastic pots filled with soil. Fertilization was conducted according to soil analysis recommendations and plants were irrigated at a 3-day interval. Morphophysiological characteristics were recorded 30 days after sowing (DAS) and 30-day intercalated evaluations were conducted up to 240 DAS. In addition, physiological indexes were estimated and leaf fall, flowering, and fruiting were evaluated at 120 DAS. Mean of each characteristic was obtained using the adjustment and the selection of regression models to explain the growth of C. procera based on the coefficient of determination. The vegetative stage of C. procera occurs during the 240 DAS, with continuous fall and production of leaves, while the reproductive stage begins at 153 DAS, continuing until 222 DAS, depending on the accession, making emission of inflorescences constant on plants after the beginning of flowering. The physiological indexes are efficient to estimate the growth of C. procera accessions.

Foram coletadas sementes de 70 acessos de C. procera entre outubro de 2015 e janeiro de 2016, em áreas de ocorrência natural da espécie, na região Nordeste do Brasil. Atualmente esses acessos compõem a coleção de germoplasma do Instituto Nacional do Semiárido (INSA). O experimento foi conduzido em casa de vegetação no INSA, em Campina Grande – PB, entre janeiro e setembro de 2016. As plantas foram cultivadas em vasos plásticos preenchidos com solo, onde foi feita a adubação conforme recomendação de análise do solo e foram irrigadas em intervalos de 3 dias. Realizaram-se leituras de características morfofisiológicas, inicialmente aos 30 dias após a semeadura (DAS) com avaliações intercaladas em 30 dias até os 240 DAS. Além disso, estimaram-se os índices fisiológicos até os 120 DAS e avaliaram-se a queda de folhas, a floração e a frutificação. Obteve-se a média de cada característica com o ajuste e seleção dos modelos de regressão para explicar o crescimento de C. procera, com base no coeficiente de determinação. O estádio vegetativo de C. procera ocorre durante os 240 DAS, com queda e produção de folhas continuamente, enquanto que o estádio reprodutivo se inicia aos 153 DAS, prosseguindo até os 222 DAS, dependendo do acesso, tornando-se constante a emissão de inflorescência nas plantas após o início da floração. Os índices fisiológicos são eficientes para estimar o crescimento de acessos de C. procera.Universidade Federal Rural do Semi-Árido2019-05-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/754810.1590/1983-21252019v32n227rcREVISTA CAATINGA; Vol. 32 No. 2 (2019); 543-551Revista Caatinga; v. 32 n. 2 (2019); 543-5511983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/7548/9970Copyright (c) 2019 Revista Caatingainfo:eu-repo/semantics/openAccessAlmeida, Isaias Vitorino Batista deRêgo, Maílson Monteiro doBatista, Fabiane Rabelo da CostaRêgo, Elizanilda Ramalho doBruno, Riselane de Lucena Alcântara2023-07-20T17:20:08Zoai:ojs.periodicos.ufersa.edu.br:article/7548Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:35.688001Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
