Inter-vine signalling via plant volatiles
Plants emit and respond to an array of volatile organic signalling molecules under conditions of biotic and abiotic stresses. Although unknown in grapevines, preliminary evidence from potted grapevines shows that water-stressed vines communicate with their well-watered neighbours and elicit a physiological water stress response.
New system for plant volatiles research, knowledge of importance of inter-vine communication under drought stress.
Benefit: Improvements in water use efficiency and irrigation management.
