Endophytes proved to exert multiple effects on host plants, including growth promotion, stress resistance. However, whether endophytes have a role in metabolites shaping of grape has not been fully understood. Eight endophytic fungal strains which originally isolated from grapevines were re-inoculated to field-grown grapevines in this study, and their effects on both leaves and berries of grape...
Recent shifts in climatic patterns have influenced the frequency, timing, and severity of heat waves many wine grape growing regions, which has introduced challenges for viticulturists. Growing same varieties under these altered conditions often requires mitigation strategies, but quantitative, generalized understanding impacts such strategies can be difficult or time consuming to determine thr...
A 2-year vineyard survey failed to the provide evidence that Uncinula necator (Schw.) Burr. survived winter as mycelium in dormant infected buds in Khorassan province. Ascospores of U. necator, were collected by a volumetric spore trap operating constantly in a vineyard for 55 days after the bud burst. The first powdery mildew colonies were consistently found on the leaves of the shoots (7.30 c...
Across plants, leaves exhibit profound diversity in shape. As a single leaf expands, its shape is in constant flux. Plants may also produce leaves with different shapes at successive nodes. In addition, leaf shape varies among individuals, populations and species as a result of evolutionary processes and environmental influences. Because leaf shape can vary in many different ways, theoretically...
This article reports the yield estimation of vineyards from using a mobile millimeter-wave radar system. The proximal sensor is 122-GHz FM-CW mounted on rover that moves along furrows between vine plants. proposed based classification echoes measured for various grape varieties, different meteorological conditions, and at stages development. As errors are found to be lower than 10%, technique s...
