The aim of this study was to assess the influence application mycorrhizal fungal inoculum on “Cabernet Sauvignon” (Vitis vinifera L.) leaf gas exchange, yield parameters, as well grape berry composition, especially regarding phenolic compounds. experiment conducted over two years under natural vineyard conditions Zagreb wine-growing area, continental region Croatia. grapevines were grafted SO4 ...

We designed nanoparticles able to protect the elicitor on leaves of grapevines over long periods time. The foliar application this nanoelicitor produced wines with high content stilbenes at significantly reduced dosages.

Plant-associated bacteria provide important services to host plants. Environmental factors such as cultivar type and pedoclimatic conditions contribute to shape their diversity. However, whether these environmental factors may influence the plant growth promoting (PGP) potential of the root-associated bacteria is not widely understood. To address this issue, the diversity and PGP potential of t...

Grape composition plays important role for wine grapes in terms of wine grape quality. Besides, monoterpenes are a chemical class of compounds present in many highly aromatic Vitis vinifera L. cultivars belonging to Muscat family and some other special cultivars. One of these special grape cultivars is Sauvignon Blanc, and in this study, cluster thinning and its treatment times were used for a ...

The genus Vitis is represented by several coexisting species in Europe. Our study focuses on naturalised rootstocks that originate in viticulture. The consequences of their presence to the landscape and to native European species (Vitis vinifera ssp. silvestris) are evaluated. This study compares ecological traits (seven qualitative and quantitative descriptors) and the genetic diversity (10 SS...

Hop stunt was a mysterious disorder that first emerged in the 1940s in commercial hops in Japan. To investigate the origin of this disorder, we infected hops with natural Hop stunt viroid (HpSVd) isolates derived from four host species (hop, grapevine, plum and citrus), which except for hop represent possible sources of the ancestral viroid. These plants were maintained for 15 years, then analy...

Abstract The supply of water to a plant canopy is dependent on the xylem pathway connecting roots leaves. In some plants, sectored pathways can restrict resource distribution, resulting in variable quality organs shoots, yet little known about effects sectoring crop cultivars. this study, we combined sap flow measurements and infusion xylem-specific dyes document functional conductive area from...

The nitrogen (N) critical level in leaves and maximum technical efficiency (MTE) doses contribute to the grape yield, must quality, fertilizers rationalization. This study aimed define sufficient ranges levels obtain high yields quality grapevines grown sandy soil a subtropical climate. ‘Chardonnay’ ‘Pinot Noir’ were subjected annual application of 0, 10, 20, 40, 60, 80 kg N ha−1 vineyard. conc...

Grape plants (Vitis vinifera L.), like other major horticultural crops, suffer from attacks by plant pathogenic nematodes. These parasites are a serious burden for viticulturists all over the world and lead to reduced vine vigour crop yield. The nematode infesting grapevines include Meloidogyne spp., Pratylenchus Criconemella Tylenchulus Helicotylenchus Heterodera spp. etc. Besides these genera...

proline and glycine betaine are the most common compatible solutes that prevent plants from destructive effects of osmotic stresses by osmotic adjustment and protection of membranes, proteins and enzymes. it has been reported that exogenous application of these compounds, can increase plant resistance to drought stress. therefore a factorial experiment based on randomized complete block design ...
