Abstract

Research was carried out in 2000 and 2001 in a fifteen-year-old Sangiovese/420 A vineyard to evaluate groundcover in an environment characterized by scarce summer rainfall. Four treatments were included: a) soil tillage; b) groundcover with natural grass; c) groundcover with Subterraneum clover; d) groundcover with Tall fescue. Readings were performed on vegetative and productive characteristics as well as on leaf gas exchanges. Results of leaf gas exchanges showed that ground cover versus soil tilling decreased net photosynthesis (A). In both years, the lowest values of A were found in vines grown with Tall fescue, while the highest values were found with soil tilling. A corresponding reduction in the transpiration rate was not observed, indicating that A reduction is regulated by a non-stomatal mechanism. Reduction of pruning material weight, shoot growth, and leaf area per vine were observed in both years in the grass-covered plots. These results show that groundcover influences vegetative activity by affecting leaf gas exchanges. Groundcover negatively affected vine yields, especially in the Tall fescue case in both years; the reduction was due to a lower cluster number as well as lower cluster weight. Time between veraison and harvest was reduced by all types of grass covers and especially by fescue. The groundcover could be used even in areas with scarce rainfall during the growing season, with positive influence on qualitative berry characteristics and harvest date.
