RESEARCH ON PHYSIOLOGICAL AND BIOCHEMICAL REACTION OF SUSCEPTIBLE GRAPE INFECTED BY ROOT-KNOT NEMATODE
In order to investigate the effects of root-knot nematode (RKN) infection on grape growth and metabolite profile, two RKN-susceptible grape cultivars Cabernet Sauvignon and Fujimineri were studied.
Metabolite profile, plant growth, root activity, free proline content and phenylalanine ammonialyase (PAL) activity were analyzed on RKN-infected grape plants in comparison to control and healthy plants.
Results showed that plant growth was reduced and root activity was increased by infection.
RKN can also increase the activity of PAL and the concentration of free proline.
The purpose of this research was to characterize changes that occur in susceptible grape plants after inoculating RKN. Furthermore we intended to screen some physiological indexes which can be used for further study.
