the effect of gibberellic acid (ga3) on jerusalem cherry (solanum pseudocapsicum l.) was evaluated at pot cultivation conditions. this study was performed in factorial test based on complete random design plan and 4 repeats with 12 treatments. the main factor was included spraying, drip and spraying + drip. secondary factor was included concentrations of ga3 at 0, 100, 200 and 400 mg.l-1 levels...
The effects of pulse treatment with gibberellin A3 (GA3), silveT thiosulfate complex (STS), and with or without sucrose on chlorophyll degTadation and vase life of cut flowers of Narcissus tazetta var. chinensis were investigated. The 20-hr pulsing treatment with STS extended the vase life of cut fiowers of IVL tazetta var. chinensis, Pulse treatments with GA3 delayed degradation of chlorophyll...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
A pot experiment was conducted in the rabi (post rainy) seasons of 2001 and 2002 to study the genotypic differences in grain growth rate and endogenous hormonal content in the developing grains of hexaploid and tetraploid wheat. The endogenous hormonal contents of grains in both the ploidy levels had changed in sequence. At 5 days after anthesis (DAA), gibberellic acid (GA3); at 15 DAA (rapid g...
In this study, favorable carbon-nitrogen ratio for high yields of gibberellic acid (GA3) production from Pseudomonas sp. was investigated. First of all, optimum carbon (glucose, maltose, sucrose, fructose, lactose) and nitrogen (KNO3, NH4Cl, NaNO3, urea, glycine) sources among the others were chosen. The highest yield of GA3 productivity was found in growth medium supplemented with fructose (16...
The Arabidopsis GA3 cDNA was expressed in yeast (Saccharomyces cerevisiae) and the ability of the transformed yeast cells to metabolize ent-kaurene was tested. We show by full-scan gas chromatography-mass spectrometry that the transformed cells produce ent-kaurenoic acid, and demonstrate that the single enzyme GA3 (ent-kaurene oxidase) catalyzes the three steps of gibberellin biosynthesis from ...
Six compounds (IBA, chlorogenic acid, cytokinine, GA3, alar B-9 and maleic hydrazide) belonging to four different categories of plant growth hormones were used to study their effect on carbohydrate content in L. erysimi. The second instar nymphs (48 hr old) were given both dipping and leaf surface treatment with 1024 ppm concentration of compounds for two time intervals i.e. 48 and 96 hr. The c...
efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
Seeds of Bauhinia acuminata L. were used as an experimental material for micropropagation. The effect of growth regulators concentrations on morphogenetic development was studied. Seeds were germinated on MS medium supplemented with GA3 (0.10, 1.0 and 2.0 mgL -1 ) and without GA3. Satisfactory germination was observed at media with 1.0 mgL -l GA3. Subsequent propagation from plantlet was perfor...
