Individuals who suffer spinal cord injury (SCI) are prone to extremely rapid bone loss. …

Reliable and valid information about plant water status is a critical input variable for optimizing citrus orchard growth. Precisely managing citrus water stress during all phenological stages enables maximized production by: avoiding drought stress during flowering and fruit sets; achieving appropriate sugar levels; and maintaining fruit quality by, for example, avoiding peel creasing for example. Controlled water status can best be …
