Gladiolus is an important marketable cut flower, especially valued for use in floral arrangements. We assessed the effects of two different methods of application (foliar spray and drench) and various concentrations of gibberellic acid (GA3), salicylic acid (SA), mival (MI) and krizatcin (KR) on vegetative and reproductive features of Gladiolus hybridus. The experiment was planned in a factoria...

one of the most effective ways to propagate lilium is by using tissue culture techniques, preferably through bulblet production. in addition to the surviving percentage of lilium bulbs after transplantation, the small size of in vitro bulblets compared to commercial bulbs and bulblets‟ dormancy are the most important constraints to commercializing lilium micropropagation. different concentratio...

fig trees are threatened by the attack of fig mosaic disease (fmd) on leaves and fruits caused by viruses of several genera. shoot-tip culture is a convenient method for viral sanitation. for this purpose, a reliable protocol for rapid in vitro propagation was developed with shoot-tips of three major tunisian local fig (ficus carica l.) varieties zidi (zdi), soltani (sni), bither abiadh (ba) an...

Cline, J. A. and Trought, M. 2007. Effect of gibberellic acid on fruit cracking and quality of Bing and Sam sweet cherries. Can. J. Plant Sci. 87: 545–550. Rain-induced cracking of sweet cherries (Prunus avium L.) is a major problem in many cherry growing regions throughout the world. One method to reduce cracking is to grow cracking resistant cultivars; however, no completely effective control...

Background: Gibberellic acids are naturally occurring plant hormones that are used in agriculture as plant regulators and enter animals and human cells through diet. This study was undertaken to investigate effects of gibberellic acid on testicular tissue of adult rats. Materials and Methods: Twenty seven adult male Wistar rats after a one week acclimatization period were randomly divided into ...

The dormancy characteristics and optimum conditions for seed germination of Alstroemeria ligtu had not been explained. In vitro and in vivo alstroemeria (A. ligtu hybrid) seed germination tests were conducted in a Randomized Completely Design at two different treatments (gibberellic acid (GA3) 0, 100, 200 and 400 mg/l with and without stratification in 5±1oC) in four replications. Seeds were pl...

Optimization studies for improvement in the yield of gibberellic acid production by Fusarium moniliforme in submerged and solid-state fermentation is the focus of this paper. In the current study, use of jatropha seed cake as substrate for solid-state fermentation resulted in an unprecedented gibberellic acid yield of 105 mg/g of moldy bran. A 2.5 fold increased in the titre resulting in 15 g g...

The effects of the plant growth promoter gibberellic acid (GA3) and plant growth retardant chlormequat chloride (CCC) on biomass and quality of Angelica dahurica var. formosana plants were investigated employing physiological and biochemical methods. Plants were sprayed with GA3 or CCC at rosette stage and coumarin content was analyzed by high performance liquid chromatography (HPLC) after harv...
