Summary: | Potassium has a great impact on plant growth. It regulates synthesis reactions and participates in the translocation of photoassimilates, cell elongation, and enzymatic reactions related to photosynthesis, respiration, synthesis of starches, proteins, and lignin. The objective of this study was to characterize the growth of cherry tomato in hydroponic system under increasing potassium doses. The experiment was arranged in a completely randomized design, with four replications. The treatments consisted of different doses of potassium (6, 8, 10 and 12 mmol L-1) evaluated at 26, 41, 56, 71, 86 and 101 DAT (days after transplanting). Accumulation of dry mass of leaves, stems, roots, flowers, and fruits; leaf area; number of flowers and fruits; length and volume of roots were determined at each evaluation time. The physiological indices studied were: relative growth rate, leaf area index and ratio, net assimilation rate, root-shoot ratio, and nutrient accumulation in leaves, stems, and roots. Potassiumdoses between 6 and 12 mmol L-1 had no influence on the growth of the cherry tomato. The relative growth rate has gradually decreased over the evaluation period. Accumulation of nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur in the leaves peaked at 101 DAT. |

Assim, objetivou-se com este trabalho caracterizar o crescimento das plantas de tomateiro cereja em sistema hidropônico, sob doses crescentes de potássio. O delineamento experimental foi inteiramente casualizado, com quatro repetições. Os tratamentos consistiram das diferentes doses de potássio (6, 8, 10 e 12 mmol L-1) e das datas de coletas aos 26, 41, 56, 71, 86 e 101 DAT (dias após o transplantio). Em cada coleta determinou-se o acúmulo de massa seca de folhas, caules, raízes, inflorescências e frutos; área foliar; número de inflorescências e frutos; comprimento e volume radicular. Calcularam-se os índices fisiológicos: taxa de crescimento relativo, razão e índice de área foliar, taxa assimilatória líquida e razão raiz-parte aérea e acúmulo dos nutrientes nas folhas, caules e raízes. Doses de potássio entre 6 e 12 mmol L-1 não influenciaram o crescimento do tomateiro tipo cereja. A taxa de crescimento relativo reduziu-se gradativamente ao longo do período de avaliação. Os acúmulos de nitrogênio, fósforo, potássio, cálcio, magnésio e enxofre nas folhas foram máximos aos 101 DAT.EDUFU2019-06-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4208610.14393/BJ-v35n3a2019-42086Bioscience Journal ; Vol. 35 No. 3 (2019): May/June; 849-858Bioscience Journal ; v. 35 n. 3 (2019): May/June; 849-8581981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/42086/26121Brazil; ContemporaryCopyright (c) 2019 Janini Tatiane Lima Souza Maia, Herminia Emilia Prieto Martinez, Paulo Roberto Cecon, Carla do Carmo Milagres, Junia Maria Clementehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMaia, Janini Tatiane Lima SouzaMartinez, Herminia Emilia PrietoCecon, Paulo RobertoMilagres, Carla do CarmoClemente, Junia Maria2022-02-01T15:06:24Zoai:ojs.www.seer.ufu.br:article/42086Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-01T15:06:24Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
