The effect of vineyard long-term monoculture soil on production of volatile compounds and photosynthetic apparatus in grapevine leaves


Svercel, M; Christen, D; Défago, G (2010). The effect of vineyard long-term monoculture soil on production of volatile compounds and photosynthetic apparatus in grapevine leaves. Vitis, 49(3):137-144.

Abstract

The effect of soil collected from long-term (1007
years of duration of monoculture) and short-term
(55 years) grapevine monoculture on production of volatile
organic compounds (VOC’s) and on functional parameters
of photosystem II in grapevine leaves was analyzed.
Grapevine plantlets grown in tested soils showed
differences in VOC’s production after five months cultivation.
Chlorophyll a fluorescence measurements by
JIP-test revealed that the photosystem II was less efficient
but the fluorescence intensity increased in plant
growing in soil from the long-term monoculture compared
to plants growing in the short term monoculture
soil. Pseudomonas spp. carrying the biocontrol genes
phlD and hcnAB were isolated from long-term monoculture
soil. A consortium of ten of these isolates was
added to the short term monoculture soil. The plants
grown in this inoculated soil showed similar changes
in fluorescence intensity and photosystem efficacy as
the plants growing in long term monoculture. In this
study, simple tools for measurement of a “soil effect”
by measuring only a leaf have been tested successfully.
They have allowed exhibiting the influence of long-term
monoculture on plant physiology.
