Special issue in honour of Prof. Reto J. Strasser - Development and aging of photosynthetic apparatus of Vitis vinifera L. during growing season

The secondary phloem of Vitis vinifera L. is characterised by a radial gradient of sieve tube diameters. Sieve tubes maturing early in the growing season have the largest diameters; those maturing late in the season have the smallest. In early spring, masses of winter dormancy callose are gradually digested in a polar radial pattern, proceeding outwards from the cambium. The fluorescent dye, fluorescein, was used to detect translocation in sieve tubes. During spring, dye translocation was first observed in the wider sieve tubes produced near the end of the previous year and wh ich had reduced amounts of callose. But translocation was not observed in the very narrow sieve tubes formed at the end of the year although they were the first to be callose free. The reactivated sieve tubes functioned for about one month. New sieve tubes differentiated three weeks after dormancy callose breakdown and started to function about one week later, so that the transition of translocation activity from the sieve tubes of the previous year to those of the current year is relatively rapid. The sieve tubes formed toward the end of the growing season (but not the narrowest ones formed at the very end of the season) function during parts of two successive seasons, while the sieve tubes forrned early in the season usually function during the first year only. Callose amounts increase gradually during summer in both the old and new sieve tubes and become relatively heavy in the old ones. At this developmental stage, translocation occurs through young sieve plates with relatively high callose deposits.

A hydrocooling system applied to Semillon (Vitis vinifera L.) grapevines as a means of protecting the vines from recurrent high temperatures. This system was assessed for impacts on vegetative and reproductive growth and development as well as for carbon economy of vines growing in vineyard conditions. The system maintained canopy temperatures at 35°C over the growing season. Leaf and bunch biomass and yield were all higher in the hydrocooled compared with control vines: the major effect was on dynamics of leaf and berry expansion. Leaf expansion was delayed and occurred over a longer duration whereas berry expansion was advanced and occurred over a longer duration than in control vines. Berry ripening was also faster in the hydrocooled vines and berries had accumulated more sugar at harvest. Leaf photosynthesis along the shoot was also higher in hydrocooled than control vines and there was a significant effect of leaf position on rates of photosynthesis of the hydrocooled vines but not with control vines. However, no differences were observed in the net shoot carbon budget. Lowered canopy temperatures were beneficial for yield and berry composition and, therefore, the cooling system warrants adoption in vineyards at risk from high temperature events during the growing season.

<p>An adequate nutritional state of a crop can be kept by means of a well-designed fertilization plan based on the assessment of the nutrient availability throughout the growing season. The objective of this study was to determine the reliability of leaf blade and petiole diagnosis and the period of validity of their references at both flowering and veraison by means of systematic monitoring throughout the complete growing season. The study was carried out in two plots planted with <em>Vitis vinifera</em> L. cv. Graciano within the AOC Rioja (Spain). Blades and petioles were collected throughout a growing season (2006) and total N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B concentrations were analyzed in both tissues. Results suggest, in general, that petioles have higher variability and lower analysis reproducibility than blades. Therefore, blade could be a more appropriate tissue to evaluate N, P, K, Ca, and Mg at both flowering and veraison in this variety. Micronutrients in blade and petiole showed different variability behaviour in each of the vineyards studied, therefore, based on our results, it was difficult to determine which one could be the best tissue for the nutritional diagnosis of the ‘Graciano’ variety. Seasonal changes of nutrient concentration in both tissues also confirmed the need for reference values for each tissue and each phenological stage.</p>

Leaf Yield

The main object of this study was to determine the effects of increasing levels of ammonium nitrate, ammonium sulphate and urea on resh the vine leaves yield in Narince grape cultivar (Vitis Vinifera L). Vines trained with bilateral cordon system was pruned to yield 5000 buds/da (24 buds/vine) above one or two buds in 2012 vegetation period. Three levels of nitrogen (0-control, 5, 10, 15 kg N /da) were applied to vines, in a split parcels with four replications. Young vine brined leaves were collected five times during growing season, and fresh brined leaves yield ( kg/da) were determined. Fertilizer form applications had significant effect on fresh leaf yield. Fresh leaf yield varied from 312.4 (Control) to 437.1 kg/da (ammonium nitrate 10 kg N/da). Vine fresh leaves yield increeased with increasing of N doses. Nitrogen applications were increased fresh leaves yield by about 30%. According to experimental results, 10 kg/da N provided the highest vine leaves yield. Ammonium nitrate treatments had given more yield vine leaves yield than the other fertilizing treatments.
