Relative water content may be accurately estimated using the ratio of tissue fresh weight to tissue turgid weight, termed here relative tissue weight. That relative water content and relative tissue weight are linearly related is demonstrated algebraically. The mean value of r(2) for grapevine (Vitis vinifera L. cv. Shiraz) leaf tissue over eight separate sampling occasions was 0.993. Similarly...

Various protocols have been developed and used for DNA extraction in grapevine. However, owing to the long duration of the isolation steps in previously developed protocols, researchers have preferred to use isolation kits for studies in recent years. In our study, the DNA yield and purity obtained using six methods--namely three DNA isolation protocols and three commercial DNA isolation kits--...

micropropagated plantlets derived from three different grape rootstock genotypes namely, dogridge (vitis champini), so4 (v. berlandieri×v. rupestris) and ari-h-144 (v. vinifera×v. labrusca) were subjected to randomly amplified polymorphic dna (rapd) and inter simple sequence repeats (issr) analyses in order to evaluate their genetic stability and/or detect likely existing variations among in vi...

abstract large-scale mortality of in vitro raisedplantlets occurred during acclimatization, i.e. glasshouse hardening, and later at field transfer still has remained as a significant bottleneck in micropropagation. the usefulness potential of some arbuscular mycorrhizal fungi (amf) to minimize mortality rate of three commercial grape rootstock genotypes during glasshouse acclimatization was stu...

A new species of Parthenocissus, P. wallichianus is described and illustrated from Kerala, India. This taxon was found collected previously India but misunderstood by earlier Indian botanists for names under various combinations among the such as Vitis, Cissus, Cayratia, Causonis. The were based either on Linnaean Vitis trifolia or Lamarck's Cissus carnosa. Both these are currently accepted con...

ABSTARCT Grape (Vitis vinifera) seed extract found to be exhibits wide range of beneficial effects insights to screen the potential compounds which includes polyphenolic compounds both flavonoids and non-flavonoids that show antioxidant effects. In this present study phytochemical screening of alkaloids, flavonoids, glycosides, polyphenol and flavonoids, tannins, and sterols were presented in t...

Eight major chemicals are identified after analyzing the essential oil of the seeds of three medicinal plants Punica granatum, Vitis vinifera and Cucurbita maxima, using Gas Chromatography/Mass Spectrometry (GC-MS). Only three of the identified chemicals (Farnesene, Docosane and Tetracosane) were found in all three samples, but in varying proportions. Trans-Squalene was found in Cucurbita maxim...

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 ...
