A factorial experiment with two factors was carried out at the Seed Technology Lab., College of Agriculture, University Baghdad in 2018 order to study effect seed priming gibberellic acid (GA3) (0, 100, 300 and 500 mgL-1) on germination seedling growth deteriorated oat cultivars (Shifaa, Shofan11). The complete randomized design used four replications. results showed that cultivars, soaking dif...

Gibberellins (GA) regulate various components of plant development. Iron and Mn plaque result from oxiding and hydroxiding Fe and Mn, respectively, on the roots of aquatic plant species such as rice (Oryza sativa L.). In this study, we found that exogenous gibberellic acid3 (GA3) spray decreased Fe plaque, but increased Mn plaque, with applications of Kimura B nutrient solution. Similar effects...

The protein mobilization from attached and detached seeds of Vicia faba L. cv. Eresen 87 (Fabaceae) was investigated. While the total soluble protein content decreased, the free amino acid content increased during the 7 days germination period. Among the three proteolytic enzymes, only endopeptidase activity was found to be affected by the removal of the embryonic axis. Leucine aminopeptidase a...

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...

in order to study the effects of cppu and ga3 on fruit quality and quantity of sultanina grapes, a factorial experiment in a randomized complete block design was implemented in a commercial vineyard near bonab city (west azerbaijan province). the spraying was done at fruit set stage using cppu and gibberellic acid. according to the results, it was found that these plant growth regulators had a ...

A two-year (2020-21) study was conducted to investigate the possibility of relying ten-years old pear trees grown on sandy loam soil irrigated by drip citric acid (CA), gibberellic (GA3) and humic (HA). The CA applied at concentrations 500, 1000 1500 ppm, GA3 50, 100 150 ppm HA 3, 4 5%, whereas water spray used as control. results our proved that CA, improved shoot length, thickness, leaf area ...

in the current study, for improving quality and quantity of ‘yaghooti’ seedless grape, gibberellic acid was sprayed in four concentrations including zero (as control), 15, 25 and 40 mg/l, at three stages, and girdling treatments were carried out simultaneously with the third step of ga3 spraying at the base of  fruit bearing shoots with four replications. the cluster length was significantly in...

This study was conducted to investigate the effect of treatment conditions plant growth regulators on marketability ‘Red Dream’, a triploid grape. In order achieve purpose this study, gibberellic acid 3 (GA3) 100 ppm single use group set as control group. addition, fruit characteristics expressed when cytokinins such thidiazuron (TDZ) or forchlorfenuron (CPPU) 2.5 5.0 mixed with GA3 were compar...

Berberis koreana Palibin is an endemic plant native to Korea. In this study, we aimed study the seed germination of species using a water imbibition experiment, gibberellic acid (GA3) treatment (0, 10, 100, or 1000 mg·L−1), cold stratification 2, 4, 8, 12 weeks at 4 °C), move-along and phenology studies. weight seeds increased by more than 120% in 24 h. An analysis internal external morphologic...

Toxicity of heavy-metals in soil is a major constraint for the production carrots (Daucus carota L.). Different plant growth regulators are being used to overcome this problem. It has been found that induce stress tolerance plants. In study, role exogenously applied regulator, gibberellic acid (GA3) was examined grown two carrot cultivars under four different levels lead (0, 50, 100, and 150 mg...
