Partial rootzone drying (PRD) and regulated deficit irrigation (RDI) has been studied in many wine-producing countries as irrigation techniques, which improves the water use efficiency, vigor control and maturation quality of wine grape production without significant crop reduction. This work aimed to compare leaf starch, reducing sugars (RS) and total soluble sugars (TSS), as well as the activities of cell wall acid invertase (CWAI), vacuole acid invertase (VAI) and citosol neutral invertase (CNI), in PRD and RDI treated vines at the São Francisco Valley (Brazil). Leaves of ?Syrah? and ?Moscato Canelli? grafted in two rootstocks (1103 Paulsen and IAC 572) were sampled throughout the day (8:00, 12:00 and 16:00 h) at the flowering, veraison and ripe fruits at June, July and August/2004, respectively. The RDI treatment induced higher leaf starch and RS contents in ?Syrah? vines. For ?Moscato Canelli? vines there was no significant difference among treatments. At flowering, in June/ 2004, the leaf carbohydrate metabolism was lower, probably due to the phenological stage and to lower temperatures and radiation. On the other hand, leaf carbohydrate contents were higher at veraison in August/2004. Leaf starch accumulation was higher at 16:00 h and TSS and RS contents were higher at 12:00 h. No differences of CWAI, VAI, CNI activities were observed among treatments, except for RDI that induced higher CWAI activity in ?Moscato Canelli?/? 1103 P?. Carbohydrate metabolism in vines was influenced by temperature and phenological stages. More studies are necessary for conclusive results for PRD and RDI influence on vine leaves carbohydrate metabolism.

The use of cropland to grow annual winter forages that are managed using direct grazing can affect the quality of the soil and the yield of summer crops grown in succession. This study aimed to evaluate the effect that the form of sowing (direct sowing an d sowing + harrowing), the deferral intervals (ungrazed and grazing stopped at 14 days and 28 days before and on the day of forage desiccation) and the fertilisation of the annual winter forage (with and without application of 8 m 3 ha-1 of poultry litter) had on the chemical properties of soil, resistance to penetration, residual forage biomass, soil cover and yield of corn and soybean from the third to the sixth year of experimentation. The forms of sowing did not affect the chemical properties of the soil, resistance to penetration, the residual forage biomass and the yield of the soybean and corn grown in rotation. The grazing of annual winter forage did not affect the chemical properties of soil and the yield of soybean and corn grown in succession, but residual forage bioma ss was reduced and resistance to penetration was increased with decreasing deferral intervals. In turn, the fertilisation of winter forages improved the quality of the chemical properties of the soil and increased the residual forage biomass and crop yields in most of the four years examined in this experiment. |
