The study aims to understand the flowering and reproductive patterns of Epimedium sagittatum, focusing on optimizing methods for assessing pollen viability and aiding in its cross-breeding.
Researchers observed the flowering process in five stages and tested five different methods to determine pollen viability, finding that the I-KI staining and peroxidase methods were the most effective.
The research concluded that the red ink staining method was the most practical for quickly detecting pollen viability, with peak pollination periods identified during specific flowering stages for successful reproduction.
