vineyard management, plant nutrition, irrigation, genotype and pests and diseases are effective factors quantity and quality of crops. among mentioned factors, plant nutrition has more importance and nutrient imbalance in soil can affect crop quantity and quality. grape cluster necrosis at veraison time is important disorders in vineyard, because of lack of balance between potassium and magnesi...

Poison ivy (Toxicodendron radicans) is a woody vine with compound leaves comprised of three leaflets. The margins of the leaflets may either be smooth, toothed or lobed. Several subspecies morphologically similar with the plant exist through the world. The plant produces clusters of small, green flowers in June or July. The fruits are small, white berries. Many bird species use the fruit as foo...

The world population is growing rapidly. As a consequence increasingly more products of crop plants are needed. Here, plant breeding gains a special significance. The goal of plant breeding is to develop new cultivars that need less nutrients and at the same time are more resistent to diseases and pests. A deciding factor is the mapping from gene analysis to the phenotype of the plant, i.e., al...

Grape is one among the most delicious, refreshing and nourishing fruits of the world. It is one of the earliest fruits grown by man. The berries are a good source of sugars and minerals like Ca, Mg, Fe, and vitamins like B1, B2, and C. Grape has so many uses and is so unique that no fruit can challenge their superiority. Crop load is the most important factor affecting yield and cluster quality...

Some cultural practices that are carried out during the grape ripening period are associated with vine stress, including leaf removal, grape bunch removal, and vegetable cover crops. Additionally, several nitrogen and sulfur supplements have also been used directly on leaves during the last stage of the ripening period. In the work described here, five different cultural practices and the refer...

Vine leaves are considered a delicacy food however they only produced as byproduct for short harvest period due to grape cultivation practices and numerous chemical applications. In this work, vine plants were cultivated hydroponically in greenhouse, extend the along with high plant density, maximize fresh yield. Four different substrates tested—Perlite, Perlite-Attapulgite, Perlite-Zeolite, 1....

In this study Illumina MiSeq was performed to investigate microbial diversity in soil, leaves, grape, grape juice and wine. A total of 1,043,102 fungal Internal Transcribed Spacer (ITS) reads and 2,422,188 high quality bacterial 16S rDNA sequences were used for taxonomic classification, revealed five fungal and eight bacterial phyla. At the genus level, the dominant fungi were Ascomycota, Sorda...

A new, commercial, fluorescence-based optical sensor for plant constituent assessment was recently introduced. This sensor, called the Multiplex(®) (FORCE-A, Orsay, France), was used to monitor grape maturation by specifically monitoring anthocyanin accumulation. We derived the empirical anthocyanin content calibration curves for Champagne red grape cultivars, and we also propose a general mode...

The paper deals with the study of the spatial distribution and the design of sampling plans for estimating nymph densities of the grape leafhopper Scaphoideus titanus Ball in vine plant canopies. In a reference vineyard sampled for model parameterization, leaf samples were repeatedly taken according to a multistage, stratified, random sampling procedure, and data were subjected to an ANOVA. The...

This study was conducted Razakı grape variety (Vitis vinifera L.) and its vine which was aged 19 was grown on 5 BB rootstock in a vegetation period of 2014 in Afyon province in Turkey. In this research, it was investigated whether the applications of Control (C), 1/3 Cluster Tip Reduction (1/3 CTR), Shoot Tip Reduction (STR), 1/3 CTR + STR, Boric Acid (BA), 1/3 CTR + BA, STR + BA, 1/3 CTR + STR...
