Bioactive gibberellins (GAs) play a key regulatory role in plant growth and development. In the biosynthesis of GAs, GA3-oxidase catalyzes the final step to produce bioactive GAs. Thus, the evaluation of GA3-oxidase activity is critical for elucidating the regulation mechanism of plant growth controlled by GAs. However, assessing catalytic activity of endogenous GA3-oxidase remains challenging....

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...

The present investigation was carried out during the year 2020-2022 in laboratory of Department Silviculture and Agroforestry, Dr YS Parmar University Horticulture Forestry, Nauni, Solan (H.P). interaction effect seed collection time (S), locations (L) pre-sowing treatments (T). seeds collected September-October from Dholra (Bilaspur) site; treated with GA3 400 ppm (S1L2T5) showed maximum germi...

priming is one of the seed enhancement methods that might be resulted in increased seed performance (germination and emergence), seedling growth and plant yield under stress conditions, such as salinity, temperature and drought stress. in order to evaluate the effect of growth hormones on morphology characteristics and essential oil of basil under drought stress condition, a experiment was cond...

The most common dwarfing genes in wheat, Rht-B1b and Rht-D1b, classified as gibberellin-insensitive (GAI) dwarfing genes due to their reduced response to exogenous GA, have been verified as encoding negative regulators of gibberellin signaling. In contrast, the response of gibberellin-responsive (GAR) dwarfing genes, such as Rht12, to exogenous GA is still unclear and the role of them, if any, ...

field trials with spathiphyllum wallisii regel 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 benzyladenine (ba) at 0, 100, 200 and 400 mg.l-1 and gibberellic acid (ga3) at 0, 100 and 200 mg.l-1 on the vegetative growth constituents of spathiphyllumplants. mo...

Adapun tujuan penelitian ini adalah untuk melihat produksi rumput gajah yang diberikan asam giberelat dengan dosis berbeda. Penelitian dilaksanakan di desa Batu Ngulik kecamatan Praya. akan pada bulan Desember sampai February 2023. Jenis eksperimen melakukan uji coba terhadap objek secara langsung. Menggunakan Rancangan Acak Lengkap (RAL). Perlakuan digunakan ada 4 yaitu level giberelat: tanpa ...

An experiment was carried out in the departmental field of Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj during February to May 2021 on bitter gourd (Momordica charantia L.) find best treatments plant growth regulators for better yield gourd. The include like GA3 NAA with different ppm. Nine were made replicated thrice randomized block design. Application done as p...

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...
