field trials with ficus benjamina l.were conducted at the experimental farm of faculty of agriculture, university azad jiroft in 2012 growth seasons. the aim of this work is to study the effect of foliar application with gibberellic acid (ga3) and benzyladenine (ba) at 0, 100 and 200 mg.l-1 on the vegetative growth and photosynthetic pigments of ficus benjamina plants. the obtained results show...

Onion (Allium cepa L.) is a biennial crop of high commercial value in Pakistan. considered as salt sensitive plant species. The present investigation was carried out to investigate the effect salinity on onion and its alleviation through exogenously applied gibberellic acid (GA3; 100 mg L-1). Foliar application GA3 (100 L-1) seedlings grown under three levels (0, 2 or 4 dS m-1) after 45 days so...

The influence of GA3 application on the fruit quality and productivity of cane pruned Thompson seedless was evaluated. Four treatments applied were: GA3, Girdle, GA3 + Girdle and control with no GA3 and no girdle were used. GA3 or GA3 + Girdle berries resulted in heavier berries, hastened berry diameter, and produced larger berries in comparison to the control grapevine trees. In addition, bunc...

The present study, "Effect of plant growth regulators on growth, fruit setting, and quality guava (Psidium guajava L.) in meadow orchard," was carried out the years 2021–2022, at Central Research Farm, Department Horticulture, Sam Higginbottom Institute Agriculture & Sciences, Prayagraj (U.P.). Ten treatments made up experiment with: control, three concentrations gibberellic acid (GA3) 75, ...

An investigation was conducted to study the effect of plant growth regulators on rice (variety Sarju-52) grown under sodic conditions, during kharifseason 2018 at students’ instructional farm ANDUA&T, Kumarganj, Ayodhya. The experiment laid out in randomized block design with nine treatments and three replications, different concentrations modes application (PGRs). PGRs were applied as foll...

Elymus sibiricus L. is an important forage grass widely distributed in Asia and is usually a dominant species on Tibetan Plateau alpine grasslands. Here, we used the seed development indices of 1000 seed weight, seed moisture content, and seed viability to compare the seed characteristics at 10, 20, 30, 40, 50, and 60 days after anthesis (DAA) in five populations of E. sibiricus growing in Gann...

This study aims to determine the effect of KNO3, H2SO4, and GA3 in breaking dormancy germination salak (Salacca zalacca) plants. In this using a non-factorial randomized block design with one factor, namely P0 (control), P1 (KNO3 60%), P2 70%), P3 80%), P4 (H2SO4 P5 P6 P7 (GA3 25 ppm), P8 50 P9 75 P10 60% P11 70% P12 80% P13 P14 P15 75). Parameters observed were germination, maximum growth pote...

The ga3 mutant of Arabidopsis is a gibberellin-responsive dwarf. We present data showing that the ga3-1 mutant is deficient in ent-kaurene oxidase activity, the first cytochrome P450-mediated step in the gibberellin biosynthetic pathway. By using a combination of conventional map-based cloning and random sequencing we identified a putative cytochrome P450 gene mapping to the same location as GA...
