In order to study the germination and growth of pepper seeds, a factorial experiment based on a completely randomized design with three replications was conducted. The first factor was consisting of five cultivars of pepper (Marquiza, Cadia, California Wonder, California Wonder 310 and California Wonder 300) and the second factor was gibberellic acid with three levels (0 as control, 250 and 500...

Tow field experiments were conducted during the seasons of 2020/2021 and 2021/2022 at experimental farm Etay El-Baroud research station to investigate effect foliar application with gibberellic acid (GA3) 50 100 ppm chitosan (CS) 200 ppm, in addition, control for each Giza Red onion. The results showed significant positive effects examined concentrations GA3 or CS on all studied characters exce...

To break dormancy and increase the germination of Prunus avium L. (mazzard cherry) seeds, various methods were tested including the removal of the seed coat after cold moist stratification and treatment with GA3, KNO3, or thiourea. Treatments with 7,500 ppm KNO3 after 120 days of stratification were more effective, yielding 64.54% germination of seeds with coat. In seeds without coat, 500 ppm G...

Prolonging the marketing period of peach fruits in Egypt through introducing new cultivars, breaking dormancy early or delaying maturity of some cultivars by safe compounds would increase the growers' profits. This study was conducted during two successive seasons 2005 and 2006 by using "Desert Red" peach cultivar (Prunus persica L.) grafted on Nemaguard rootstock. Trees were grown at El-Noubar...

Faba bean (Vicia faba L.) as the most cultivated leguminous species in the world, is an excellent source of protein, dietary fiber, micronutrients and phytochemicals. A field experiment was conducted at Ghazala, Zagazig University, Sharkia Governorate during 2015, to study the effect of plant Growth Regulator such as; Gibberellic acid (GA3) and Inidol acetic acid (IAA) on antioxidant contents o...

A study was conducted to determine the optimum concentration of benzyladenie (BA) and gibberllic acid (GA3) to break the dormancy of gladiolus corms in relation to storage period and to find out the effect of BA and GA3 on growth and development of gladiolus corm and cormels. The effect of GA3 on dormancy breaking was most pronounced in the 100 ppm treatment being 26.93 days while in the water ...

BACKGROUND Arbutus unedo is a valuable Mediterranean shrub as an ornamental plant as well as fruit tree. Fresh fruits of A. unedo are a good source of antioxidants, of vitamins C, E and carotenoids and also are characterized by the high content of mineral elements. MATERIALS AND METHODS The effects of gibberellic acid (GA3) and cold stratification (CS) on seed germination performance were inv...

Purpose: The study aimed to overcome the seed dormancy of Datura stramonium L. by chemical scarification, pre-chilling, and different gibberellic acid (GA3) levels.
 Materials Methods: seeds were prechilled at 4°C 10°C for 7 days treated with sulfuric (97-98% H2SO4) 15 minutes, increasing doses GA3 (250, 500, 1000 ppm). Distilled water hydration untreated served as a control.
