This study investigated the developmental toxicity of a plant growth regulator (a type of pesticide) using the frog embryo teratogenesis assay-Xenopus (FETAX). Xenopus laevis embryos were exposed to 11 different concentrations of gibberellic acid (GA3), from stage 8 to 11, for 96 h under static renewal test conditions. The median lethal concentration (LC50), malformation (EC50), non-observed ad...

Tubers of safed musli (Chlorophytum borivilianum) were immersed in three different concentrations of gibberellic acid (GA3) or humic acid (HA) prior to planting. The highest concentration of GA3 (20 mg L(-1)) and all concentrations of HA (5, 10, and 15%) appeared to hasten tuber sprouting and promote uniform sprouting pattern. The use of 20 mg L(-1) GA3 or 15% HA successfully improved sprouting...

Response of five induced plant height mutants (dwarfs and semi-dwarfs) of barley to gibberellic acid (GA3) treatment was studied. The gibberellic acid response index (GRI) was calculated and based on this value, the mutants have been categorized as sensitive (high or moderate) or insensitive. The GRI value was highest for dwarf mutant followed by early maturing mutant with the former being high...

leaf yellowing is a major problem in postharvest of alstroemeria cut flowers. for delaying of leaf yellowing and increasing flower quality a completely randomized factorial design was carried out on the alstroemeria cut flowers (‘fuji’ cultivar). in this research ethanol (0, 2, 4, 6%), ga3 (0, 50, 100, 150 mg/litre) in two methods (pulse and continuous) were investigated on the flower vese life...

The aim of this study investigate the toxicity effect of (GA3) on liver & kideny function, activity of acetylcholine and antioxidant at different doses as well as the possibility of recovery after apostasy GA3 Twenty five adult male albino Rats were .equally divided into five groups. Group 1 served as control. Groups 2&3 received GA3 daily in drinking water in two gradually increasing doses of ...

The effects of N-benzyladenine (BA) and N-(2-chloro-4-pyridyl)-N-phenylurea (CPPU) in combination with gibberellic acid (GA3, 100 mg l ) on berry setting and development and on the endogenous level of polyamines (PAs ) were investigated in order to elucidate the role of PAs in the setting and development of GA3-induced seedless grape berries affected by cytokinins. BA stimulated berry developm...

Despite problems of low fruit set, small fruit size and alternate bearing, the Hass cultivar dominates commercial avocado production worldwide. To increase yield and fruit size, gibberellic acid (GA3) (25 mg L−1) was applied at different stages of ‘Hass’ avocado tree phenology: (i) mid–late April (flower abscission), end of June–beginning of July (fruit abscission and beginning of the exponenti...

Ralstonia sp. strain GA3-3 is a hexachlorocyclohexane (HCH)-degrading bacterial strain isolated from suburban soil in Canberra, Australia. The genome of strain GA3-3 was sequenced to investigate its ability to degrade α-HCH. Here, we report the annotated genome sequence of this strain.
