In an effort to improve and promote the propagation of Terminalia sericea, the effects of temperature, photoperiod and growth regulators on seed germination were investigated. Seeds were tested with different temperature regime (10, 15, 20, 25, 30, 35 and 40C) and in photoperiod (4/20, 8/16, 12/12, 16/8 light/dark hrs and 24 hours continuous dark). Pre-treatments with growth regulators were don...

the aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. velvet. hence, an experiment involving the pulsing treatment with gibberllic acid (ga3) at 0, 20, 40 and 60 mg l-1, for 2...

effect of gibberellic acid on marigold (calendula officinalis l.) was evaluated in a pot culture experiment. a factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. main factor was foliar application stages (first, second and third) and sub factor included different concentrations of ga3 (0, 50, 150 and 250 mg l-1). results sho...

The effects of N-benzyladenine (BA) and N-(2-chloro-4-pyridyl)-N-phenylurea (CPPU) in combination with gibberellic acid (GA3, 100 mg l ) on berry setting and development and on the endogenous level of polyamines (PAs ) were investigated in order to elucidate the role of PAs in the setting and development of GA3-induced seedless grape berries affected by cytokinins. BA stimulated berry developm...

The roles of gibberellic acid (GA3) and abscisic acid (ABA) in the regulation of vacuolar pH (pHv) in aleurone cells of barley were investigated using the pH-sensitive fluorescent dye 2[prime],7[prime]-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. BCECF-loaded aleurone cell...

Cycad is one of the most important cut foliage plants with several usages. This experiment was focused on increasing the vase life of Cycad’s cut foliage in normal storage condition. Experiment was based on a CRD with three replications. Treatments were conducted for four different levels of gibberellic acid (GA3) and benzyl adenine (BA) each one with 0, 50, 100 and 150 mg L-1, according to men...

An experimental trial was carried out during the season from March 2018 – June at Horticulture farm of Lovely Professional University, Phagwara (Punjab). utilising a randomised block design, consists three replications. The current study included eleven treatments, including control with different PGR dosages Maleic hydrazide (200, 250, and 300 ppm, MH), Naphthalene acetic acid (50, 100, 150ppm...

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...

Abstract Gibberellic acid (GA3) is a plant growth hormone that plays an important role in the production of crops, fruits, and vegetables with wide market share. Due to intrinsic advantages, liquid fermentation Fusarium fujikuroi has become sole method for industrial GA3 production, but broader application hindered by low titer. In this study, we combined atmospheric room-temperature plasma (AR...

Background: Plant growth regulators (PGRs) have important roles in many processes such as germination, seedling growth, nutrition uptake, morphogenesis, ripening, etc. Objective: This study aimed to evaluate the effect of gibberellic acid, indole butyric acid, and methanol as plant growth regulators on morpho-physiological and phytochemical features in Thymus vulgaris L. Methods: The farm...
