1、Efficiency of paclobutrazol and gibberellic acid in wheat (Triticum

The results showed that application of paclobutrazol and gibberellic acid raised super wheat yield and quality compared to control.

2、Understanding the Role of Gibberellic Acid and Paclobutrazol in

Sustainable food production is always at increased risk due to abiotic stresses. The high-temperature stress, especially at the reproductive stage, i.e., terminal heat stress, poses a threat to global crop production.

3、Understanding the role of gibberellic acid and paclobutrazol in

However, the information on role of gibberellic acid (GA) in abiotic stress tolerance in late sown wheat is insufficient in literature. Thus, we aimed to investigate the role of endogenous GA3 level in stress tolerance in contrasting wheat cultivars viz., temperature tolerant (HD 2643 and DBW 14) and susceptible (HD 2

4、Gibberellic Acid3 Modifies Some Growth and Physiologic Effects of

Abstract. Gibberellic acid 3 (GA 3) modification of some growth and physiologic effects of paclobutrazol (PP 333) was studied by applying PP 333 alone and in combination with GA 3 at the tillering stage of wheat.

5、Effect of gibberellic acid, salicylic acid and paclobutrazol on

To study the effects of hormones on seed ageing, aged wheat seeds (control, 90 and 80% viabilities) were treated with GA 3 , salicylic acid and paclobutrazol and antioxidant system was...

COMBINED EFFECT OF GIBBERELLIC ACID AND PACLOBUTRAZOL ON WHEAT PLANTS

Tow field experiments were conducted in alkaline saline soil of newly reclaimed lands at Abou-Mady region "North of Della" during the two successive seasons of 2001/2002 & 2002/2003.

Effect of Gibberellic acid and Paclobutrazol on Growth and Chemical

Table 7. Effect of gibberellic acid and paclobutrazol on dry weight (g/ plant) of leaves, stems and roots of Schefflera arboricola during 2007 and 2008 seasons.

Effects of applied gibberellic acid and paclobutrazol on leaf expansion

We studied the effects of exogenously supplied GA3 and paclobutrazol, an inhibitor of GA biosynthesis, on these processes in Aegilops caudata and Aegilops tauschii, species with contrasting leaf growth characteristics.

Understanding the Role of Gibberellic Acid and Paclobutrazol in

Thus, we aimed to investigate the role of endogenous GA 3 level in stress tolerance in contrasting wheat cultivars, viz., temperature-tolerant (HD 2643 and DBW 14) and susceptible (HD 2189 and HD 2833) cultivars under timely and late sown conditions.

The effects of paclobutrazol, abscisic acid, and gibberellin on

The inhibitory effect of paclobutrazol plus abscisic acid (ABA) on the shoots of silver maple could not be overcome by a brief treatment with gibberellic acid A 3 (GA 3).

Paclobutrazol, gibberellic acid (GA), and allyl isopentenyladenine (AIDA) are three commonly used plant growth regulators in agriculture. They play critical roles in promoting plant development, increasing yields, and improving crop quality.

1. Paclobutrazol

Paclobutrazol is a plant growth retardant that inhibits cell division, thereby slowing plant growth. It is primarily used to control excessive vegetative growth, prevent overly tall plants, and enhance fruit weight. In fruit tree production, paclobutrazol is often applied to apple, pear, and other trees to promote compact fruiting, improve fruit quality, and increase yield. Additionally, it is used in crops like cotton and wheat to suppress excessive growth, boost yield, and improve lodging resistance.

2. Gibberellic Acid (GA)

Gibberellic acid is a plant hormone that stimulates stem elongation, leaf expansion, and flowering/fruiting. Widely used in agriculture, GA promotes crop growth, yield, and stress resistance. For example, it enhances development and stress tolerance in rice, maize, and wheat. GA also improves fruit quality and productivity in fruits, vegetables, and other crops.

3. Allyl Isopentenyladenine (AIDA)

AIDA is a plant growth stimulant that promotes stem elongation, leaf expansion, and flowering/fruiting. In agricultural applications, AIDA increases crop yields and quality by accelerating growth and stress resistance in plants such as rice, maize, wheat, fruits, and vegetables.

These three regulators have distinct mechanisms but collectively influence hormonal balance in plants. Paclobutrazol suppresses gibberellin synthesis, inhibiting growth; GA promotes gibberellin synthesis, stimulating growth; and AIDA inhibits ethylene synthesis, delaying senescence and abscission.

Practical Applications

In agriculture, paclobutrazol, GA, and AIDA can be used individually or in combination for optimized results. For example:

• Fruit trees: Paclobutrazol controls excessive growth, while GA and AIDA enhance fruit development.
• Grain crops: Paclobutrazol prevents overgrowth, and GA/AIDA boost yield and stress resistance.
• Vegetables: Paclobutrazol manages height, while GA/AIDA improve growth and quality.

Paclobutrazol, GA, and AIDA are versatile tools in agriculture, effectively enhancing plant growth, yield, and quality. their application must adhere to proper dosage and methods to minimize environmental and health risks.
