The application of Sodium 1-Naphthyl Acetate in fruit tree fruit retention techniques primarily encompasses the following aspects:

Applicable Plant Types
1. Grain Crops: Rice, wheat, corn, etc. Application during the tillering stage increases the number of effective tillers; application during the grain-filling stage prevents premature senescence.

Plant Growth Regulators (PGRs) are a class of compounds—either chemically synthesized or extracted from biological sources—that structurally resemble and functionally mimic natural plant hormones. However, they possess the unique ability to precisely regulate vital crop processes

Gibberellic Acid is not merely a simple fertilizer or hormone; rather, it is a naturally occurring signaling molecule found within plants. It precisely regulates the plant's entire life cycle, from germination through to fruit-bearing.
