Predicting coffee water potential from spectral reflectance indices with neural networks. Author(s): NUNES, P. H.; PIERANGELI, E. V.; SANTOS, M. O.; SILVEIRA, H. R. O.; MATOS, C. S. M. de; PEREIRA, A. B.; ALVES, H. M. R.; VOLPATO, M. M. L.; SILVA, V. A.; FERREIRA, D. D. Leaf water potential is one of the main parameters used to assess water relations in plants by revealing levels of tissue hydration. It is commonly measured with the Scholander pressure chamber; which... ... Repository: BDPA Publication year: 2023
Leaf water potential of coffee estimated by landsat-8 images. Author(s): MACIEL, D. A.; SILVA, V. A.; ALVES, H. M. R.; VOLPATO, M. M. L.; BARBOSA, J. P. R. A. de; SOUZA, V. C. O.; SANTOS, M. O.; SILVEIRA, H. R. DE O.; DANTAS, M. F.; FREITAS, A. F. de; SANTOS, J. O. DOS Traditionally, water conditions of coffee areas are monitored by measuring the leaf water potential throughout a pressure pump. However, there is a demand for the development of technologies that can... ... Repository: BDPA Publication year: 2020
A spatial analysis of coffee plant temperature and its relationship with water potential and stomatal conductance using a thermal camera embedded in a remotely piloted aircraft. Author(s): SANTOS, L. M.; FERRAZ, G. A. e S.; CARVALHO, M. A. de F.; CAMPOS, A. A. V.; MENICUCCI NETO, P.; XAVIER, L. A. G.; MATTIA, A.; BECCIOLINI, V.; ROSSI, G. Coffee is a key agricultural product in national and international markets. Physiological parameters, such as plant growth indicators, can signal interruptions in these processes. This study aimed to... ... Repository: BDPA Publication year: 2024
Deficit irrigation in table grape: eco-physiological basis and potential use to save water and improve quality. Author(s): PERMANHANI, M.; COSTA, J. M.; CONCEIÇÃO, M. A. F.; SOUZA, R. T. de; VASCONCELOS, M. A. S.; CHAVES, M. M. Table grapes are one of the most productive and economically relevant fruit crops worldwide. Table grape production characterizes by high water productivity but also by an intensive use of water, whic... ... Repository: BDPA Publication year: 2016
Water potential in peach branches as a function of soil water storage and evaporative demand of the atmosphere¹. Author(s): MONTEIRO, B. A.; REISSER JUNIOR, C.; ROMANO, L. R.; TIMM, L. C.; TOEBE, M. Repository: BDPA Publication year: 2018

Use of lower quality water in irrigated agriculture and effects on forages with productive potential in Semiarid regions: a review. Author(s): ARAÚJO JÚNIOR, G. do N.; MORAIS, J. E. F. de; SOUZA, L. S. B. de; STEIDLE NETO, A. J.; ARAUJO, G. G. L. de; SILVA, T. G. F. da In the agricultural sector, using lower quality water sources has increased in irrigation practice. Thus, this review summarizes the consequences of using brackish and/or saline water in irrigated agr... ... Repository: BDPA Publication year: 2023
Growth, photosynthesis and leaf water potential in young plants of Copaifera langsdorffii Desf. (Caesalpiniaceae) under contrasting irradiances. Author(s): RONQUIM, C. C.; PRADO, H. B. A. P.; SOUZA, J. P. de Growth and leaf nutrient content were compared in young potted plants of Copaifera langsdorffii in sunny and shaded areas without water stress. Besides, carbon assimilation and leaf water relations we... ... Repository: BDPA Publication year: 2009
