The ripening of grape (Vitis vinifera L.) is characterized by massive sugar import into the berries. The events triggering this process and the pathways of assimilate transport are still poorly known. A genomic clone Vvht1 (Vitis vinifera hexose transporter1) and the corresponding cDNA encoding a hexose transporter whose expression is induced during berry ripening have been isolated. Vvht1 is e...

The spider Latrodectus hesperus Chamberlin & Ivie (Araneae: Theridiidae) was subjected to low and ultralow oxygen (ULO) treatments at different temperatures. Complete control of the spiders was achieved in 24-h ULO treatments with 0.5% O2 or lower at 1 degrees C and in a 24-h low oxygen (2%) treatment at 15 degrees C. Oxygen level and temperature greatly affected spider mortality. At 1 degrees ...

Grapes (Vitis L.), one of the most important and old fruit crops in world, are grown a wide range environments from Australia to North America Japan Chile. All grape growing countries use both international local cultivars production obtain fresh dried fruits or wine. In Turkey, each region has their own cultivars. Seven standard cultivar, Coruh valley, were analyzed for morphological traits (b...

Introduction Fungicides have been widely used on nearly every crop imaginable and are continually being developed and reformulated as more information on their efficacy on specific crops and pathogens is discovered. It is well known that fungicides are developed and used in order to have a direct effect on one or more pathogens, usually to prevent their establishment on a crop. By spraying fung...

Development of electronic technologies for precise identification fruit crop cultivars in agricultural production provides an effective means assuring product quality and authentication. The capabilities discriminating between grape (Vitis vinifera L.) is essential certification varieties sold world markets. Machine olfaction, based on electronic-nose (e-nose) technologies, readily available ra...

G grown in Kentucky are subject to environmental stresses that reduce crop yield and quality, and injure and kill grapevines. Damaging critical winter temperatures, late spring frosts, short growing seasons, and extreme summer temperatures all occur with regularity in regions of Kentucky. However, despite the challenging climate, certain species and cultivars of grapes are grown commercially in...
