Rachises of grape (Vitis vinifera L.) clusters that appeared healthy or displayed symptoms of the ripening disorders berry shrivel (BS) or bunch-stem necrosis (BSN) were treated with the cellular viability stain fluorescein diacetate and examined by confocal microscopy. Clusters with BS and BSN symptoms experienced a decrease of cell viability throughout the rachis, and their berries contained ...

partial rootzone drying (prd) is a new irrigation technique which improves water use efficiency without significant yield reduction in grape. to study the effects of partial rootzone drying and green pruning on yield and yield quality of thompson seedless grape a split plot experiment with randomized complete block design and three replications was conducted. the experiment was performed in tak...

Panax ginseng has long been used as a traditional herbal medicine. More recently, it has received attention for its anti-diabetic and anti-obesity effects in humans and in animal models of type 2 diabetes. In the present study, we tested the hypoglycemic effects of ginseng berry extract in beta-cell-deficient mice and investigated the mechanisms involved. Red (ripe) and green (unripe) berry ext...

grape vine is one of the important horticultural crops with unique standing as regards use and consumption. the fruit is utilized from immature to ripened state and as raisins. its leaves can be used when they are soft and fresh. therefore it is necessary to improve iranian grapevine quality as well as quantity. the main purpose of this study was the use of phenyl phetalamic acid (ppa) to incre...

Highbush blueberry (Vaccinium corymbosum L.) is an important crop grown throughout Florida. Currently, most blueberry growers use honey bees (Apis mellifera L.) to provide pollination services for highbush blueberries even though bumble bees (Bombus spp.) have been shown to be more efficient at pollinating blueberries on a per bee basis. In general, contribution of bumble bees to the pollinatio...

Berry size of winegrapes has often been considered to influence wine composition and quality. The measurement of the size and weight of grapevine berries may provide important information to assess differences in ripening stage, pulp/skin ratio and phenolic content. This task is usually done by hand, so that it becomes slow, tedious and inaccurate. This paper focuses on three main objectives ai...

in order to study the effect of grapeguard on quality, quantity and control of storage diseases of grape in cold storage a completely randomized design with 3 replicate was conducted on two cultivators of kolahdari and kajanguri in khorasan agricultural research center. the fruits after harvesting were transferred to the sheltered place. before keeping in cold storage, the temperature of fruits...

Canopy shading is a widely used viticultural strategy for mitigating early grape berry ripening caused by global warming. In this study, we covered half of the canopy with black shade cloth from pea-size stage to harvest. fruit zone, treatment (ST) reduced daily average solar radiation about 74.6 % compared untreated control (UC), and significantly temperature. ST leaves were found have lower n...
