Callus Induction and Somatic Embryogenesis in Muscadine and Seedless Bunch Grapes (vitis) from Immature Ovule Culture
Pre-embryogenic calli were obtained from the culture of fertilized immature ovules of muscadine ( Vitis rotundifolia Michx.) and seedless bunch grapes ( Vitis vinifera L.) on: 1) Murashige & Turcker (MT, 1969) basal medium supplemented with 4.4 μM 2, 4-D (2, 4-dichlorophenoxyacetic acid) and 1 μM BA (6-benzyladenine) with 6.0% (w/v) sucrose; 2) Chee and Pool (CP, 1978) basal medium supplemented...
متن کاملPhenolic profiles and antioxidant properties of young wines made from Yan73 (Vitis vinifera L.) and Cabernet Sauvignon (Vitis vinifera L.) grapes treated by 24-epibrassinolide.
The grape berries of two varieties, Yan73 (Vitis vinifera L.) and Cabernet Sauvignon (CS) (Vitis vinifera L.) were treated with 0.40 mg/L 24-epibrassinolide (EBR), 1.00 mg/L brassinazole (Brz), and deionized water (control), at the veraison period. The EBR treatment significantly increased total phenolic content (TPC), total tannin content (TTC) and total anthocyanin content (TAC) of Yan73 and ...
متن کاملIn vitro Regeneration of Grape (Vitis vinifera L.) cv. Perlette
Factors like slow and seasonal multiplication and infection with pathogens have constrained the use of conventional plant propagation methods, thus lead to development of new and novel methods of propagation like in vitro multiplication which ensures the production of virus and disease free elite planting material in large numbers. In the present work, in vitro regeneration protocol has been st...
متن کاملAntioxidant and Antiproliferative Activities of Twenty-Four Vitis vinifera Grapes
Grapes are rich in phytochemicals with many proven health benefits. Phenolic profiles, antioxidant and antiproliferative activities of twenty-four selected Vitis vinifera grape cultivars were investigated in this study. Large ranges of variation were found in these cultivars for the contents of total phenolics (95.3 to 686.5 mg/100 g) and flavonoids (94.7 to 1055 mg/100 g) and antioxidant activ...
متن کاملIn Vitro Antioxidant and Antimicrobial Activities of Grapes (vitis Vinifera. L) Seed and Skin Extracts - Muscat Variety
The skins and seeds of grapes are known to be rich sources of phenolic compounds, both flavonoids and non-flavonoids. The aim of the present study is to determine polyphenolic composition, antioxidant potential along with free radical scavenging activity and antimicrobial properties of ethanol extract of Grape skin and seed. Grape seed showed high antioxidant and antimicrobial activity compared...
