Quercetin haze has been observed over the last few years in some aged Sangiovese wines. This problem could be due to an excess of quercetin wine. Leaf removal increases exposition clusters sunlight, which may enhance flavonol synthesis grapes. In this study, we evaluated dynamics related extractable flavonols grapes grown three usually defoliated Vitis vinifera (L.) cv. vineyards, whose wines s...

Perennial grasses undergo compensatory growth after defoliation. Nitrate is the main nitrogen source for of perennial ryegrass and plays a significant role in plant resistance to stress. The aim study was understand physiological mechanism response defoliation stress under different nitrate supplies explore possible ways alleviate We performed pot experiments where 12-week-old plants grown low ...

In recent decades, a considerable number of sensors have been developed to obtain 3D point clouds that great potential in optimizing management agriculture through the application precision techniques. order use data provided by these sensors, it is essential know their measurement error. this paper, methodology presented for obtaining cloud central axis training system defoliated fruit tree (M...

Recent drought-induced dieback alters forest dynamics, which are also shaped by past management. In western Pyrenean silver fir (Abies alba) stands, concurs in space and time with the legacies of management, but impacts on growth, structure composition unknown. We aim to disentangle how interacts human use modulates recent dynamics forests. To this end, we sampled eleven forests across wide cli...

Efficient herbicide absorption and translocation, satisfactory weed control can be affected by the site of application. However, during harvesting crops previous soybean sowing, cutting process made harvesters on fleabane may generate a difficult management in pre sowing crop limiting leaf area herbicide. Experiments were conducted to evaluate efficiency translocation potential saflufenacil pla...

Fluctuating asymmetry (FA), defined as small, random departures away from perfect symmetry, is frequently recommended a sensitive and universal indicator of environmental stress imposed by both abiotic biotic factors. However, the sensitivities FA other morphological traits are rarely compared directly. Here, we tested hypothesis that leaf FA, rather than size, more to simulated herbivory. We p...

Maize is one of the most productive crops whose seeds are used in poultry sector as main ingredients their diet. It also important forage for ruminants silage. The aim this research was to assess effect defoliation and detopping on dual-purpose maize production field (Kermanshah, Iran, Mediterranean climate conditions) laboratory experiments. study included a control (intact plant), removal lea...

Forest health and multifunctionality are threatened by global challenges such as climate change. is currently assessed within the pan-European ICP Forests (International Co-operative Programme on Assessment Monitoring of Air Pollution Effects Forests) programme through evaluation tree crown conditions (defoliation). This paper analyses results a 24-year assessment carried out in Italy 253 perma...
