Effects of mycorrhizal roots and extraradical hyphae on N uptake from vineyard cover crop litter and the soil microbial community
The objectives of this study were to evaluate the contribution of arbuscular mycorrhizal (AM) fungal hyphae to N uptake from vineyard cover crop litter (Medicago polymorpha), and to examine the soil microbial community under the influence of mycorrhizal roots and extraradical hyphae. Mycorrhizal grapevines (Vitis vinifera) were grown in specially designed containers, within which a polyvinyl ch...
متن کاملCutting wild grapevines as a cultural control strategy for grape berry moth (Lepidoptera: Tortricidae).
A 3-yr field study was conducted at commercial grape farms to evaluate cutting wild grapevines as a cultural control strategy for grape berry moth, Paralobesia viteana (Clemens). At each farm, wild grapevines were cut in the woods adjacent to one vineyard for control of P. viteana, whereas the comparison vineyard received no such cutting. Both vineyards received a standard broad-spectrum insect...
متن کاملIntelligent irrigation in grapevines: a way to obtain different wine characteristics
This work presents the field implementation of an intelligent irrigation controller, applied to grapevine crops. The proposed irrigation system includes the moisture measurements and the development of an intelligent control system, in order to maintain the moisture level around a set value. Moisture reference value for different irrigation treatments, such as water stress or field capacity, is...
متن کاملControl of Pierce's Disease by Phage
Pierce's Disease (PD) of grapevines, caused by Xylella fastidiosa subsp. fastidiosa (Xf), is a limiting factor in the cultivation of grapevines in the US. There are presently no effective control methods to prevent or treat PD. The therapeutic and prophylactic efficacy of a phage cocktail composed of four virulent (lytic) phages was evaluated for control of PD. Xf levels in grapevines were sign...
متن کاملHigh Constitutive Overexpression of Glycosyl Hydrolase Family 17 Delays Floral Transition by Enhancing FLC Expression in Transgenic Arabidopsis
Vitis vinifera glycosyl hydrolase family 17 (VvGHF17) is a grape apoplasmic β-1,3-glucanase, which belongs to glycosyl hydrolase family 17 in grapevines. β-1,3-glucanase is not only involved in plant defense response but also has various physiological functions in plants. Although VvGHF17 expression is negatively related to the length of inflorescence in grapevines, the physiological functions ...
