1、Effects of Foliar Application of Paclobutrazol on Grain Yield, Aroma

Paclobutrazol (PBZ) is extensively used to modulate plant architecture in rice. However, its comprehensive effects on grain yield and aroma in aromatic rice have not been thoroughly investigated.

2、Foliar spraying with paclobutrazol at the canopy rapid growth stage

Proper concentrations of paclobutrazol enhance the physiological activity and stress resistance of sugar beet leaves. Both sugar beet yield and taproot sugar content are increased by paclobutrazol. Paclobutrazol’s effect on yield and sugar content varied depending on sugar beet cultivar.

3、Paclobutrazol as a plant growth regulator

In this review, the current knowledge and possible applications of PBZ, which can be used to improve the growth, yield and quality of crops, have been reviewed and discussed. The role of PBZ to mitigate the harmful efects of environmental stresses in crops is also examined.

These results indicate that foliar application of PBZ at 150 mg L−1 can effectively improve both yield and aroma of aromatic rice, offering a promising cultivation strategy for high-quality aromatic rice production. Paclobutrazol (PBZ) is extensively used to modulate plant architecture in rice.

Application of NPK Fertilizer and Paclobutrazol on Growth

The study results showed that there was an interaction between NPK fertilizer and the concentration paclobutrazol on number of flower and size of flower diameter.

Research Progress on Role and Mechanisms of Foliar Fertilizer in

Finally, the problems existing in the practical application of foliar fertilizers and the prospects for further exploring the mechanism by which foliar fertilizers regulate plant growth and development are discussed and prospected.

Paclobutrazol enhances lodging resistance and yield of direct

Foliar application of paclobutrazol improved the canopy light transmittance and leaf photosynthetic capacity by regulating leaf morphology and stem structure, reducing the lodging risk and ensuring the formation of DSR yield.

Foliar fertilizers and paclobutrazol are two common plant growth regulators that play critical roles in agricultural production. Foliar fertilizers are primarily used to supplement soil nutrients and promote crop growth, while paclobutrazol controls plant development to prevent excessive growth. Below is a detailed explanation of their functions:

1. Functions of Foliar Fertilizers

Foliar fertilizers are substances sprayed directly onto plant leaves to provide nutrients. Their key roles include:

(1) Supplementing Soil Nutrients Foliar fertilizers effectively replenish essential nutrients like nitrogen (N), phosphorus (P), and potassium (K) in the soil, enhancing soil fertility. This is vital for increasing crop yields and improving quality.

(2) Promoting Crop Growth These fertilizers contain microelements and hormones that stimulate plant growth, strengthen pest and disease resistance, and enhance stress tolerance. Additionally, they boost photosynthesis, increasing photosynthate production and yield.

(3) Improving Crop Quality Foliar fertilizers enhance attributes such as fruit taste, color, and nutritional value, boosting market competitiveness.

(4) Reducing Fertilization Costs By acting directly on crops, foliar fertilizers minimize nutrient loss and waste compared to traditional application methods, lowering agricultural costs.

2. Functions of Paclobutrazol

Paclobutrazol, a plant growth retardant, primarily inhibits excessive growth. Its specific functions are:

(1) Controlling Plant Height It suppresses stem elongation, dwarfing plants to enable denser planting, which increases per-unit-area yields.

(2) Preventing Lodging By slowing stem growth and reducing flexibility, paclobutrazol reduces the risk of crops lodging under wind, protecting them from natural disasters.

(3) Enhancing Stress Resistance It strengthens pest and disease resistance, improving survival under adverse conditions and ensuring agricultural stability.

(4) Promoting Fruit Development Paclobutrazol aids fruit enlargement, coloring, and overall quality, elevating market value.

Foliar fertilizers and paclobutrazol are indispensable in agriculture. The former supplements nutrients, promotes growth, and improves quality, while the latter regulates growth, prevents excess expansion, and boosts resilience. For optimal results, farmers should select these tools based on crop requirements and growth stages.
