In this study, the effects of foliar kaolin particle film treatment (PF) on some table grape quality characteristics cv. Trakya Ilkeren grown in Ankara conditions were investigated. The application (3%) was started just after fruit set. Treatments repeated weekly for three weeks. Yield per vine found to be 3.60 kg Control (C) and 3.93 PF treatment. No significant effect yield determined. TSS ma...

ABSTRACT Resistance of mature berries of grapevine cultivars and selections to postharvest infection by Botrytis cinerea was assessed. Little or no resistance existed in most popular table grape Vitis vinifera cultivars, except in moderately resistant 'Emperor' and 'Autumn Black'. Highly resistant grapes were V. rotundifolia, V. labrusca, or other complex hybrids. Morphological, anatomical, and...

Measurement of carbon isotope discrimination in berry juice at maturity (δ13C) provides an integrated assessment vine water status and use efficiency (WUE) during the period ripening, when collected over multiple seasons, can provide indication drought stress responses. Berry δ13C measurements were carried out on 48 different varieties planted a common garden experiment Bordeaux, France from 20...

In this study, some quality elements of the Horoz Karası grape variety were investigated. For purpose, cluster, berry, total soluble solids (TSS), titration acidity, pH level, berry color, phenol, and antioxidant activity determined in sample clusters taken from producer vineyards Kahramanmaraş. cultivar, (TSS) level was recorded between 16.6-25.35%, titratable acidity 0.189-0.517, 3.62 3.94. s...

BACKGROUND The study on phytochemical difference between red and black goji berry is limited. METHODS Antioxidant activities and phenolic profiles in terms of total phenol content, total flavonoid contents, condensed tannin content, monomeric anthocyanin content, and total carotenoid content of red goji berry (Lycium barbarum) and black goji berry (L. ruthenicum) were compared using colorimet...

generally, fruit trees should produce sufficient yield annually through their economic life. fruit trees usually produce flowers over their ability of productivity. if all of the flowers are converted to fruit, the tree will be weak and poor smaller fruit will be produced and it may cause alternate bearing. thus some flowers must be removed by hand, mechanically or chemically. in this study, th...

The coffee berry borer (CBB) (Hypothenemus hampei: Ferrar) was first detected in Puerto Rico in 2007. Its distribution since then has been extensive, but not extensively documented. An island-wide survey was carried out from August to November 2014 (the coffee production season) to assess CBB distribution, infestation, and population per fruit. The CBB was well-established throughout the coffee...

The present trial follows a previous study about pre-flowering leaf removal (LR) (Verdenal et al., 2019) and validates the sustainability of mechanical LR under local Swiss vineyard conditions, using low-pressure double airflow, to reduce cost laborious bunch thinning. In studies, has shown additional benefits over post-berry-set in terms yield regulation grape wine compositions. This had two o...
