Abstract The aim of the present study was to identify grape parent varieties that lead greater frequency seedless genotypes in progenies and understand relationships between trait other fruit traits. A group 200 hybrids (F1) originating from 38 crosses among cultivars Vitis vinifera L. interspecific were evaluated Juazeiro, Bahia, Brazil, over six consecutive crop seasons (2018 2021). placed th...

Quantitative and qualitative analysis of phenolics and boron in stigma of transient sterile Tecoma stans L. during seedless (May-July), partially seedbearing (August-November, April) and seedbearing periods (December-March) was made. UV absorption profile of stigmatic exudates indicated the presence of simple phenolics. Total phenolics were higher in stigma during seedless period. Thin layer ch...

Fruit development in higher plants normally requires pollination and fertilization to stimulate cell division of specific floral tissues. In some cases, parthenocarpic fruit development proceeds without either pollination or fertilization. Parthenocarpic fruit without seed has higher commercial value than seeded fruit. Several apple (Malus domestica) mutants (Rae Ime, Spencer Seedless and Welli...

This research was aimed at establishing high-quality and abundant cocoon cultivation in the country, to create new nutritious mulberry varieties gradually introduce them into production. In order local varieties, for first time viability of silkworm hybrids “Jararik-9”, “Jararik-10” determined by level productivity technological impact. The coefficient leaves eating hybrid worms determined. bel...

The aim of this study was to determine anthocyanin content and antioxidant activity of 20 different grape varieties, using HPLC and DPPH, FRAP and ABTS assays, respectively. The identified anthocyanins were malvidin-3-glucoside, delphinidin-3-glucoside, petunidin-3-glucoside, cyanidin3 glucoside, and peonidin-3-glucoside on the basis of their retention times. Comparatively the total anthocyanin...

Objective: Due to rich resources of phenolic components such as anthocyanin and flavonoids, grape has grabbed lots of attention. Antioxidants are the frontline of the human immune system against free radicals and they are of high importance for the human health. Methods: In order to determine antioxidant activities, the amount of phenols, anthocyanin and ascorbic acid of 2 grapes’ varieties ("w...

The aim of the research was to study and isolate promising seedless grape varieties with a complex economically valuable traits adapted arid conditions Northwestern Caspian Sea. objectives included: studying features annual biological cycle grapes, determining leaf area studied varieties, assessing growth strength degree ripening shoots, dynamics shoots. studies were conducted in 2020...2021 vi...

As a result of the conducted research, it was established that varietal characteristics influence interphase periods white cabbage and its yield. The duration period "stairs – beginning formation heads" varied in studies. During cultivation Slavia Slava 1305 varieties, "seedlings 88 89 days, respectively, but plants variety are characterized by more pronounced early maturity compared to varieti...
