Resumo: | The objective was to evaluate beet cultivars subjected to salinity during the germination and seedling emergence phase. A completely randomized design was used, arranged in a 3x5 factorial scheme, with four replications. The treatments consisted of three beetroot cultivars (Betty RZ F1, Bettollo and Scarlet Super F1) and five irrigation water salinity concentrations of 0, 50, 100, 150 and 200 mM corresponding to Electrical Conductivities of 0, 6.00, 10 .25, 12.44 and 14.40 dS/m. The percentages of germination and emergence, the germination and emergence speed index (IVG and IVE), mean germination and emergence time (TMG and TME) of the seedlings were calculated. The cultivar Bettollo obtained the best average germination and emergence percentage in the EC of 6.00 dS/m, as well as Scarlet Super at the concentration of 10.25 dS/m, suggesting that these cultivars are more tolerant to these concentrations. Cultivar Betty showed lower germination and emergence at all concentrations. Bettoloo and Scarlet Super suffered decreases both in germination percentage and in emergence in saline concentrations from 10.25 dS/m. The highest EC of water promoted a reduction in the percentage of Germination and IVG, generating an extension of the TMG for all cultivars. The high saline concentrations make it difficult for water to enter the seed, consequently causing a reduction in seedling height, and in the radicle and hypocotyl length of all evaluated cultivars. |

Se utilizó un diseño completamente al azar, arreglado en un esquema factorial 3x5, con cuatro repeticiones. Los tratamientos consistieron en tres cultivares de remolacha (Betty RZ F1, Bettollo y Scarlet Super F1) y cinco concentraciones de salinidad del agua de riego de 0, 50, 100, 150 y 200 mM correspondientes a Conductividades Eléctricas de 0, 6.00, 10.25, 12.44 y 14,40 dS/m. Se calcularon los porcentajes de germinación y emergencia, el índice de velocidad de germinación y emergencia (IVG e IVE), tiempo medio de germinación y emergencia (TMG y TME) de las plántulas. El cultivar Bettollo obtuvo el mejor porcentaje promedio de germinación y emergencia en la CE de 6,00 dS/m, así como Scarlet Super a la concentración de 10,25 dS/m, lo que sugiere que estos cultivares son más tolerantes a estas concentraciones. El cultivar Betty mostró menor germinación y emergencia en todas las concentraciones. Bettoloo y Scarlet Super sufrieron descensos tanto en los porcentajes de germinación como de emergencia en concentraciones salinas desde 10,25 dS/m. La mayor CE de agua promovió una reducción en el porcentaje de Germinación y IVG, generando una extensión de la TMG para todos los cultivares. Las altas concentraciones salinas dificultan el ingreso de agua a la semilla, provocando consecuentemente una reducción en la altura de las plántulas, y en la longitud de la radícula y del hipocótilo de todos los cultivares evaluados.Objetivou-se avaliar cultivares de beterraba submetidas à salinidade durante a fase de germinação e emergência das plântulas. Foi utilizado o delineamento experimental inteiramente casualizado, disposto em esquema fatorial 3x5, com quatro repetições. Os tratamentos consistiam em três cultivares de beterraba (Betty RZ F1, Bettollo e Scarlet Super F1) e cinco concentrações de salinidade da água de irrigação 0, 50, 100, 150 e 200 mM correspondendo às Condutividades Elétricas de 0, 6,00, 10,25, 12,44 e 14,40 dS/m. Foram calculadas as porcentagens de germinação e emergência, o índice de velocidade de germinação e emergência (IVG e IVE), tempo médio de germinação e emergência (TMG e TME) das plântulas. A cultivar Bettollo obteve as melhores médias de porcentagem de germinação e emergência na CE de 6,00 dS/m, assim como a Scarlet Super na concentração de 10,25 dS/m, sugerindo que estas cultivares sejam mais tolerantes a estas concentrações. A cultivar Betty apresentou menor germinação e emergência em todas as concentrações. Bettoloo e Scarlet Super sofreram decréscimos tanto na porcentagem de germinação como na emergência nas concentrações salinas a partir de 10,25 dS/m. As maiores CE da água promoveram a redução da porcentagem de Germinação e do IVG, gerando o prolongamento do TMG para todas as cultivares. As altas concentrações salinas dificultam a entrada da água na semente ocasionando consequentemente a redução da altura de plântula, e do comprimento da radícula e do hipocótilo de todas as cultivares avaliadas.Research, Society and Development2022-05-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2968610.33448/rsd-v11i7.29686Research, Society and Development; Vol. 11 No. 7; e9411729686Research, Society and Development; Vol. 11 Núm. 7; e9411729686Research, Society and Development; v. 11 n. 7; e94117296862525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/29686/25661Copyright (c) 2022 Antonia Mirian Nogueira de Moura Guerra; Louhanny Carvalho Machadohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGuerra, Antonia Mirian Nogueira de MouraMachado, Louhanny Carvalho2022-06-06T15:12:05Zoai:ojs.pkp.sfu.ca:article/29686Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:46:41.829414Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
