Effects of Exogenous Gibberellic Acid on Yield Components of ‘Askari’ Grape
Abstract The most important commercial use of gibberellin in horticulture is to improve the yield and marketability of table grapes. This experiment was conducted in order to evaluate the effect of different concentrations of gibberellic acid on yield components of five-year-old ʻAskariʼ seedless grapevines, based on a randomized complete block design. Gibberellic acid was sprayed on the folia...
متن کاملSodium bisulfite improves rhizome yield and quality in Paris polyphylla.
Rhizomes of the perennial herb Paris polyphylla have been used in traditional Chinese medicine for hundreds of years. Agricultural production of the rhizomes requires 7-10 years, which is too long to meet the demand of the medicinal industry. Therefore, studies on improving the yield of the herb and shortening the culturing period are imperative. The present work aimed to investigate the effect...
متن کاملIn-vitro Antitumor Activity and Antifungal Activity of Pennogenin Steroidal Saponins from paris Polyphylla var. yunnanensis
Paris polyphylla Smith var. yunnanensis, has been used in traditional Chinese medicine for its antibiotic and anti-inflammatory properties; in addition it has been used to cure liver cancer in particular. In this current study, β-ecdysterone (1) and three pennogenin steroidal saponins (2-4) were isolated from the EtOH extract of Paris polyphylla var. yunnanensis, and then tested for their antit...
متن کاملEthylene-induced Leaf Abscission Is Promoted by Gibberellic Acid.
Gibberellic acid (GA(3)) promoted leaf abscission from cotton (Gossypium hirsutum L.) plants exposed to ethylene. With mature plants, only the rate of abscission was increased, but when vegetative plants were exposed to ethylene for 4 days or less, the amount of abscission was increased markedly. Promotion of abscission occurred at near saturating ethylene levels (10 mul/liter), over a wide ran...
متن کاملProduction of gibberellic acid by fermentation.
The elonigationi of rice plants iinduced by the application of cell-free culture filtrates from the li(uid culture of Futsariutm moniliforme was first demonstrated in 1926 by Kurosawa. Twelve years later, Yabuta and Sumiki (1938) were able to isolate in crystalline form two growth-promotinig compounds, gibberellins A and B, from filtrates of this organism; gibberellin A was the maini substaniee...
