The Seedling Culture Test with Culm Node of Sympodial Bamboo Species for Pulping

The seedling culture test with node of such sympodial bamboo species for pulping as Bambusa textilis var. fasca Macclure, B. multiplex (Loun) Racuschel ex Schut f.and B.gibba Macclure suggested that within burying methods the flat burying is better than the slant or vertical ones with the best effect of flat burying of bamboo stump. There is significant difference between different bamboo species in seedling culture survival rates with bamboo node,that survival rates differ in node age, and there is no significant difference between different seedling growing seasons(March or May).The seedling culture test with different thickness,position,single-or double-internode suggested that survival rates with thinner culm(2.5 cm in diameter),higher position and double-internode are better than those with thicker culm(4.6 cm in diameter),lower position and single-internode.The survival rates differ between hormone treatments with the best effects of 2,4-D(20 mg/kg,5 h) or boric acid(20 mg/kg).
