Plant growth retardants are applied in agronomic and horticultural crops to reduce unwanted longitudinal shoot growth without lowering plant productivity. Most growth retardants act by inhibiting gibberellin (GA) biosynthesis. To date, four different types of such inhibitors are known: (a) Onium compounds, such as chlormequat chloride, mepiquat chloride, chlorphonium, and AMO-1618, which block ...

Split plot design experiments were conducted to assess the performance of growth regulating compounds for mitigating moisture stress and incidence Brown Plant Hopper (BPH) in rice. The main treatments (4) comprised free control (M1), during panicle initiation stage alone (M2), flowering (M3), both stages (M4). sub-plot (5) foliar application including chlormequat chloride at 200 ppm (S1), mepiq...

Wheat is the cereal most susceptible to lodging, particularly during flowering period and at early ripening stage. The use of plant growth retardants (PGRs) especially recommended when intensive nitrogen (N) fertilisation applied, which increases susceptibility plants lodging. This paper presents results tests into effects PGRs (PGR0—control; PGR1—chlormequat chloride (CCC) + trinexapac-ethyl (...

Many plant growth regulators (PGRs) are known to alleviate the negative effects of drought stress in plants. However, limited research has been conducted to investigate the potential benefits of exogenous application of PGRs in wheat plants grown under drought stress. In the present study, effects of salicylic acid (SA) and chlormequat chloride (CCC) on drought-stress induced changes in morpho-...

the effects of the plant growth promoter gibberellic acid (ga3) and plant growth retardant chlormequat chloride (ccc) on biomass and quality of angelica dahurica var.formosana plants were investigated employing physiological and biochemical methods. plants were sprayed with ga3 or ccc at rosette stage and coumarin content was analyzed by high performance liquid chromatography (hplc) after harve...

It is known that most chemicals, which have been increasingly used since ancient times, carcinogenic and mutagenic effects. As an alternative to these natural compounds, such as plant growth regulators (PGRs) used. However, are the PGRs obtain efficient plants in agriculture harmless it thought today when essential access foods food sectors? Therefore, this study investigates activity of two (K...

The effects of four plant growth regulators on Crocus sativus L. (saffron) yield and performance were studied in two consecutive years under field conditions. Saffron corms immersed solutions gibberellic acid (GA3), salicylic (SA), paclobutrazol (PBZ), chlormequat chloride (CCC), distilled water (hydroprime), dry as the control. Results showed that among different treatments, plants primed with...
