Abstract

Abstract: To explore the effects of different disinfection methods and germination matrix of rhododendron, 10 species of Rhododendron L. were tested, disinfection treatment were as follows, disinfect with a concentration of 0.3% of the potassium acid solution for 10 minutes, disinfect with 1% sodium hypochlorite solution for 10 minutes, disinfect 10 min with 0.1% Hg solution, disinfect with 70% alcohol for 30 seconds +1% sodium hypochlorite for 10 minutes,disinfect with 70% alcohol for 30 seconds+0.1% Hg solution for 10 minutes. In addition, the germination rate, germination potential and germination time of 10 species of Rhododendron L. seeds were determined by filter paper, sponge, gauze and specific culture medium. The results showed that, different disinfection methods had different effects on germination rate and germination potential of different Rhododendron L.. But on the whole, the germination rate and germination potential of 1%NaClO and 70% alcohol +1%NaClO were higher than other disinfection methods. And the delay of germination were also significantly shorter than other disinfection methods. Agar culture medium was suitable for most of the Rhododendron L. seed germination, and the gauze was not suitable for germination matrix of Rhododendron L. seed .

Key words: Rhododendron L., seed, germination, disinfection method, germination matrix
