In the present study, eight kinds plant growth regulators—salicylic acid (SA), 1-naphthaleneacetic acid (NAA), gibberellic acid (GA3), 6-benzylaminopurine (6-BA), 2, 4-epi-brassinolide (EBR), abscisic acid (ABA), ethephon (ETH), and spermidine (SPD)—were used to investigate the impact on microalgal biomass, lipid, total soluble protein, carotenoids, and polyunsaturated fatty acids (PUFAS) produ...

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...

OBJECTIVE To develop a protocol for breaking of seed dormancy and increasing the seed germination rate of Bunium persicum. METHODS The seeds were treated with 3.1, 6.3, 12.5, 25, 50 and 100 µmol/L of benzyl aminopurine, gibberellic acid (GA3), thidiazuron (TDZ) and forchlorfenuron. Then, seeds were transferred to two different temperature conditions including room temperature (25 °C) and chil...

An experiment was carried out by considering adverse impact of heavy metals on human health through consumption crops. To alleviate the effects cadmium (Cd) toxicity foliar application gibberellic acid (GA3), two varieties Brassica including Indian mustard (Brassica juncea (L.) Czern.) commonly known as ‘Raya’ and rapeseed rapaL.) ‘Toria’ were studied. The Completely Randomized Design (CRD) use...

The effects of single and combined growth regulator treatments of indole-3-acetic acid (IAA), gibberellic acid (GA3) and coconut milk on plant height, yield, chlorophyll and vitamin contents of Abelmoschus esculetus L and Solanum gilo L were investigated. The single growth regulator treatments consisted of 50mg/L, 100 mg/L of IAA and GA3 and 10%, 15% of coconut milk. In case of combined growth ...

A significant stimulation (2- to 2.5-fold) of AdoMet synthetase was witnessed in glibberellicd acid (GA3, 1 microM)-treated epicotyls of the dwarf pea (Pisum sativum). This was accompanied by a 2.4-fold increase in the endogenous pool of S-adenosylmethionine. Both abscisic acid (10 microM) and cycloheximide (20 micrograms/ml) inhibited the GA3-mediated enhancement of AdoMet synthetase activity....

the effect of gibberellic acid (ga3) spraying on some characteristics of cyclamen flowering trend during the second flowering year was investigated. ga3 sprays were applied in concentrations of 0, 20, 30, 40, and 50 mg/l. the trial was carried out as a randomized complete design of three replications. the total flower count, flower count during the flowering peak, days from spraying to flowerin...
