Biomass accumulation, plant biometrics and fruit production of watermelon according to changes in source/drain relations

Abstract: The objective of this study was to evaluate the accumulation of biomass, plant biometrics and production of watermelon fruit submitted to changes in source and drain relations. The experiment was conducted in the experimental area of the CCTA/UFCG, PB, Brazil, during the period from September to December, 2013. Seed of the cultivar "Crimson Sweet" were used and the treatments were allocated in 2x4 split plots, with four replications. Plots consisted of plants grown with different number of fruits (1 and 2) and… Show more

“…SS and TA were, in general, higher in the first crop cycle, which may be explained by the lower number of fruits produced, which caused a higher leaf area per fruit and less drains of synthetized photoassimilates, such as sugars and organic acids, as found for melon (Dalastra et al, 2014) and watermelon (Lins et al, 2016) fruits.…”

“…Ghebremariam (2004) raleando o primeiro, segundo e terceiro fruto da pimenteira 'Challenger', comparado ao tratamento controle, obteve aumento na massa dos frutos em 32% quando submetidos ao raleio. O aumento no número de frutos leva a uma competição por assimilados entre drenos levando a diminuição do peso individual dos frutos (Lins, Queiroga, Pereira, Silva, Albuquerque 2013).…”

“…A massa média dos frutos (MMF) de pepino foi reduzida em função do aumento da concentração de nutrientes na solução nutritiva ( Figure 1B), sendo registrados valores de MMF oscilando entre 326,48 a 438,44 g. Essa redução foi inversamente proporcional a emissão de frutos por plantas, indicando que as plantas mesmo cultivadas com maior disponibilidade de nutrientes, não apresentam capacidade de elevar a fotossíntese liquida suficiente para produzir um grande número de frutos, sem afetar a massa média do fruto, apresentando com isso, uma baixa relação fonte:dreno (LINS et al, 2016).…”
