GUTIERREZ-SOTO, Marco V; CALDERON-CERDAS, Rubén  y  ARAYA-ALFARO, José Miguel. Bubble manometers for the continuous measurement of root pressure in tropical crops. Agron. Mesoam [online]. 2011, vol.22, n.2, pp.405-414. ISSN 2215-3608.

Bubble manometers for the continuous measurement of root pressure in tropical crops. The objective of this technical note is to introduce a low-cost bubble manometer to measure root pressure in different environments, where it is a major component of several physio-pathological disorders of crop plants. The concept and mechanisms of root pressure are explained, its putative functions, and its association with various physiological disorders such as fruit and stem cracking, leaf infiltration and burst, guttation and plant surface wetness, and the development of several preand post-harvest diseases. The construction, installation and functioning of bubble manometers to measure root pressure is described. The importance of controlling root pressure as part of the root-zone management strategy is discussed, which includes interventions the physical, chemical, and biological properties of soil and substrates, especially near and around the rhizosphere, and of the aerial environment of crop plants

Palabras clave : Guttation; physiological disorders; substrate; water uptake and transport; xylem.
