| description | Several physiological and environmental factors can influence the development and growth of vines cultivated in irrigated areas of the Brazilian semi-arid region. Therefore, it is necessary to characterize the phenology of ‘Sweet Sunshine’ grapevine under Sub-medium São Francisco Valley, Brazil conditions in order to set up the managements employed for the crop. To characterize the phenology 12 plants were selected, distributed in four repetitions, from the first growing season, both in the 2nd half of 2012 as in the 1st half of 2013. The observations of plant development phases were initiated immediately after pruning, ending at the harvest. Gas exchange measures as net CO2 assimilation rate, stomatal conductance, transpiration rate, intercellular CO2 concentrations, water use efficiency, apparent carboxylation efficiency (Rubisco) and the photosynthetic photon flux density were performed at inflorescence, early flowering, growth and softening of berries phases. The productive characterization was performed weekly, determining the clusters fresh weight length; fresh weight, diameter, length and volume of the berries; soluble solids content and titratable acidity; fresh and dry weight, basal, median and apical diameter of the stems. It was found that physiological parameters induced changes in the characteristics of the plants for the two evaluated periods, since the behavior of the curve for gas exchange measurements were distinct, exhibiting productive and commercial potential. |

São vários os fatores fisiológicos e ambientais que influenciam o desenvolvimento e crescimento de videiras cultivadas em áreas irrigadas do semiárido brasileiro. Assim, caracterizar a fenologia da videira ‘Sweet Sunshine’ nas condições do submédio do Vale do São Francisco fez-se necessário, para definir os manejos comumente empregados na videira. Para a caracterização da fenologia foram selecionadas 12 plantas, distribuídas em 4 repetições, a partir do primeiro ciclo vegetativo, tanto no 2º semestre de 2012 como no 1º semestre de 2013. As observações das fases de desenvolvimento das plantas foram iniciadas logo após a poda, finalizando na colheita. As medidas de trocas gasosas como: taxa de assimilação líquida de CO2, condutância estomática, taxa de transpiração, concentração interna de CO2, eficiência do uso da água, eficiência de carboxilação aparente (Rubisco) e a densidade de fluxo de fótons fotossinteticamente ativos, foram realizadas nas fases de inflorescência, início de florescimento, crescimento e amolecimento de bagas. A caracterização produtiva foi realizada semanalmente, determinando a massa fresca e comprimento de cacho; biomassa fresca, diâmetro, comprimento e volume de baga; teor de sólidos solúveis e acidez titulável; biomassa fresca e seca, diâmetro basal, mediano e apical do engaço. Verificou-se que os parâmetros fisiológicos promoveram alterações nas características das plantas entre os dois períodos, pois os comportamentos das curvas das medidas de trocas gasosas foram bem distintos, apresentando potencial produtivo e comercial. 2016-12-27 2022-03-21T20:07:48Z 2022-03-21T20:07:48Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://comunicatascientiae.com.br/comunicata/article/view/1148 10.14295/cs.v7i3.1148 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/77770 por https://comunicatascientiae.com.br/comunicata/article/view/1148/413 application/pdf Federal University of Piauí Comunicata Scientiae; Vol. 7 No. 3 (2016); 319-333 Comunicata Scientiae; v. 7 n. 3 (2016); 319-333 2177-5133 2176-9079 |
