Abstract

The germination rate of conventional seed treatment for Acer fabri is relatively low. It is of great significance to study seed propagation methods to improve germination rate of A. fabri. The seeds of A. fabri should be harvested in November and stored in wet sand till February or March next year. Cool storage or room temperature storage is not conducive to the germination of A. fabri. After pregermination, the seeds can be sown in sandy soil and the germination rate could reach more than 70%. The cutting scions of A. fabri may not be processed, or may be treated by 100 PPM Indolebutyric acid on the scion base, and the rooting rate reached 94%, the average number of lateral roots per plant reached 3.6, and the average lateral root length reached 5.3 cm. Too many roots generated while the base of scions was treated with 1000 PPM or 2000 PPM Indolebutyric acid, and the plantlets grew slowly. A. fabri contains high endogenous hormone, so low concentration IBA or no growth regulator treatment is beneficial to root and later growth. The results provide practical mass production techniques for A. fabri.
