The process related to the changes in dimensions and mass of grape berry passes through two growth phases separated by a lag phase, can be described double sigmoid curve. onset their duration are important factors for understanding processes berries. A new method quantitative determination was developed present study. In this method, phase transition dates correspond times at which rate change ...

The effect of Meloidogyne incognita on growth, general physiological response, and the concentrat ion of reducing and nonreducing sugars at the nematode feeding sites of French Colombard (susceptible) and Thompson Seedless (moderately resistant) Vitis vinifera cultivars was studied up to 2,100 degree-days (DD-base 10 C). Nematode stress dosage, measured as the product of cumulative number of ju...

Grapes are important sources of phenolic compounds, which have multiple beneficial effects on human health. Scientific advances in the field genetics allowed production seedless table grape varieties, highly demanded by consumers because their nutritional value and easy consumption. In this study, total content (TPC), radical scavenging activity (RSA) anthocyanin (TAC), were determined 65 varie...

embryogenic calli production in vitis is mainly possible by use of such regenerative tissues as anther and ovary. because of long periods of time required for obtaining such tissues, use of such vegetative organs as leaf explant would be a promising alternative. towards this end, leaf explants were taken from two varieties of ‘flame seedless’ and ‘red sultanina’ to be raised in. ms medium, cons...

Given a family of Abelian varieties over a positive-dimensional base, we prove that for a sufficiently general curve in the base, every rational section of the family over the curve is contained in a unique rational section over the entire base. 1. Main results sec-intro The starting point for this article is the following theorem. Theorem 1.1. [GHMS05, Theorem 6.2] Let B be a smooth, quasi-pro...

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...
