Advanced techniques using the plant as indicator of irrigation management

Técnicas avançadas utilizando a planta como indicadora do manejo de irrigação

Abstracts

The methodologies which are considered the most promising for irrigation management are those based on the analysis of the water status of the plants themselves. This justifies the study and improvement of indicators based on automatic and continuous measures to enable real-time monitoring data, as indices from sap flow, dendrometry and leaf turgor pressure techniques. The aim of this paper is to analyze such methodologies in order to demonstrate their principles, advantages and challenges. In conclusion, the methodologies analyzed still have many technological advances and challenges before being presented to the final user. The future research should work these tools for elaboration of technical indexes that allow their simplification, on the instrumental point of view, and the interpretation of their results.

sap flow; dendrometry; leaf turgor pressure.

As metodologias que se apresentam como as mais promissoras para o manejo de irrigação são aquelas baseadas na análise do status hídrico das próprias plantas. Isso justifica este estudo e o aprimoramento de indicadores baseados em medidas automáticas e contínuas que permitam acompanhamento em tempo real dos dados, como os índices provindos das técnicas do fluxo de seiva, dendrometria e da pressão de turgescência foliar. Nesse sentido, esta revisão se propõem a analisar tais metodologias de maneira a demonstrar seus princípios, vantagens e desafios. Como conclusão, tem-se que as metodologias analisadas ainda têm diversos desafios tecnológicos para serem apresentadas de maneira satisfatória ao usuário final. As pesquisas devem trabalhar estas ferramentas para elaboração de índices técnicos que permitam sua simplificação, tanto do ponto de vista instrumental, quanto para a interpretação dos seus resultados.

  ERRATUM

  Artigo "Advanced techniques using the plant as indicator of irrigation management" publicado no fascículo v45n5 de maio da Ciência Rural páginas 821-827 sem a inclusão de duas citações e correspondentes referências, onde se lia:
  "In the case that the irrigated plant is considered in isolation, such as in an orchard, for example, the biggest problem is to determine the volume of water to be applied for each time period and the moment it should be applied. This is due to the little knowledge about the amount of water used by a plant during its transpiration with the soil in excellent water conditions."
  "Plant indicators have been used, primarily in research, as methods for estimating water stress; and their practical applications in irrigation management are still being developed."
