Gibberellic Acid-induced Seedlessness in Field-grown Vines of `Swenson Red' Grape

Effect of Pre-Harvest Application of Gibberellic Acid and Ethephon on the Quality of Table Grape

In this study the effects of plant growth regulators including; GA3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (Perlette and Yaghuti). At the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and L/D ratio, flesh firmness, fresh weight, TA, pH, TSS and fruit color were ...

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...

Purification of gibberellic acid-induced lysosomes from wheat aleurone cells.

Using isopycnic density gradient centrifugation, lysosomes were concentrated in a single region of a sucrose-Ficoll gradient (p = 1-10 g cm-3), well separated from most other cell organelles. Gibberellic acid-induced lysosomes were found to be rich in alpha-amylase and protease but not ribonuclease. The lysosomal band also contained a majority of the NADH2-cytochrome c reductase, a marker enzym...

Interactions affecting gibberellic acid

The production of GA3 in solid-state culture was studied using systems composed of maize cob particles soaked in an amylaceous efluent, as a function of three variablesparticle diameter, volume of liquid phase, and substrate concentration-with a determinant influence on the response. The empirical model obtained provides an explanation of the behavior of the system in terms of a series of inter...
