Evaluating the effectiveness of plant growth regulators requires a comprehensive assessment based on a "blank control" setup and multi-dimensional indicator monitoring. By considering the specific functions of the regulators, one should evaluate results across four key areas

Gibberellic Acid 90% TC is highly active; it must be dissolved and diluted precisely according to specifications to safely and effectively break seed dormancy and promote rooting and germination, while avoiding issues such as leggy growth or phytotoxicity.

DA-6 98% TC possesses extremely high activity; it must never be sprayed directly. Strict adherence to dilution protocols is essential to ensure safety and efficacy without causing phytotoxicity.

For propagation via cuttings, three types of auxin-based growth regulators—Indole-3-acetic acid (IAA), Indole-3-butyric acid (IBA), and Naphthaleneacetic acid (NAA)—offer the most outstanding overall rooting performance.
