Assessment of the viability of using saline reclaimed water in grapefruit in medium to long term

open access: yesSpanish Journal of Agricultural Research, 2014
Citrus trees are strongly affected by salinity, especially in countries where irrigation is required as a semi-arid Mediterranean agronomic region. The aims of the study were i) to identify the best reliable plant-based water status indicator for field ...

Internal Plant-water-status and Its Control

open access: yesJournal of Agricultural Meteorology, 1976
The present paper deals with an experimental method for evaluating the plant water status. An apparatus which enables continuous and nondestructive measurement of internal plant water stress has been developed by making use of a strain-gauge. The apparatus shown in Fig.
