Research on Effect Factors for Rhizome Planting of Phyllostachys aureosulcata f. spectabilis

Using the 1 ～ 3-year-old rhizome with dense and strong buds and adopting the rhizome culture method,we discussed the effects of culture temperature,hormone treatment together with their own characteristics on seedling cultivation of Phyllostachys aureosulcata f.spectabilis.The results showed that the culture temperature of 18 ℃ was the best for bud sprouting and bamboo shooting,with a respective rate of 93.11%,and 81.83%.The 2-year-old rhizome with 2 centimeters in diameter reached a fastest rate of 63.33%.The bamboo shoot coefficient of 60 cm long rhizome was highest under the treatment of 300 mg / L ABT.The rhizome length,the types and concentrations of hormone were revealed as key factors of rhizome cultivation of Phyllostachys aureosulcata f.spectabilis.
