In this research, our aim was to determine the effects of gibberellic acid, which was applied to safflower plants (Carthamus tinctorius L. cv. Dinçer 5-118) for pollen sterility induction, on some physiological activity and endogenous hormone levels of the seeds. Exogenously applied gibberellic acid (GA3) strongly influenced the endogenous hormone levels of the seeds by decreasing the levels of...

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...

Effects of doses of gibberellic acid (GA3) were studied on the growth and performance of strawberry cultivar ‘Chandler’. GA3 was applied as foliar spray at three leaf stages @ 50, 75, 100 and 150 ppm. The applied GA3 @ 150 ppm significantly increased the plant height, leaf area index (LAI), crown size and fruit yield. However, this dose of GA3 (150 ppm) significantly decreased the shelf life an...

The content of gibberellic acid (GA3) in male sex organs of Chara tomentosa L. was estimated using capillary electrophoresis. Young antheridia contained 0.25 microg GA3 while mature ones 0.48 microg per antheridium. Although there are significant differences in GA3 content in antheridia between C. vulgaris and C. tomentosa, these values calculated per one spermatid are 2.4 and 3.3 pg, respectiv...

Green skin (hull) of pistachio fruits is a barrier against the penetration of fungi and insects into the kernel of pistachio. Splitting of husk facilitates the entry of fungi and infection of pistachio kernels during the harvest. So far no effective way has been reported for controlling this problem. To evaluate the effects of gibberellic acid on hull spliting the present research was conducted...

The roles of gibberellic acid (GA3) and abscisic acid (ABA) in the regulation of vacuolar pH (pH,) in aleurone cells of barley were investigated using the pH-sensitive fluorescent dye 2',7'-bis(2-carboxyethyl)-5(6)-carboxyfluorescein (BCECF). BCECF accumulated in vacuoles of aleurone cells, but sequestration of the dye did not affect its sensitivity to pH. BCECFloaded aleurone cells retained th...

Kaurenoic and grandiflorenic acid, isolated from Wedelia paludosa (Asteraceae), some derivatives from these acids (alcohols, esters, amides, lactones, oximes) and other naturally occurring kaurane diterpenes were tested for their action on the growth of radical and shoot of Lactuca sativa. Gibberellic acid, GA3, a commercially available phytohormone, belonging to the same class of diterpenes, w...

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...

The experiment was performed to evaluate the effect of GA3, 2,4-D on fruit growth and fruit quality of wax apple. The experiment consisted of Red A, Monulla, Atu, Red B cultivars. GA3 and 2,4-D were applied at the small bud and petal fall stage. Physiological, biochemical characters of fruit were recoded. The result showed application of GA3, 2,4-D greatly response in increasing fruit set for a...
