摘　　要：部分竹种的幼嫩鞭梢可以食用，生产中称为鞭笋。鞭笋营养丰富，是群众喜爱的绿色森林食品和时令蔬菜，特别是在夏秋季鲜笋供应淡季，质优、味美的鞭笋既可满足广大消费者的需求，也能切实提高竹林的经济效益。目前生产鞭笋的竹种很少，主要是毛竹（Phyllostachysedulis（Carr．）H．de Le-hale），有必要开发生态适应性强，鞭笋产量高、质量好的竹种进行鞭笋林经营，以促进区域高效特色竹笋业发展。鞭笋品质主要包括外观品质（鞭笋的个体大小、基径和长度等）和内在品质（营养物质和呈味物质）。营养物质含量高低主要影响鞭笋的营养价值，Phyllostachys prominens with high potential of rhizome shoot production and strong elongation growth of rhizome is an excellent bamboo species used both for shoot and timber. The appearance quality, the contents of nu- trient substances, flavour substances and amino acid in rhizome shoot of Ph. prominens were compared with the rhi- zome shoot of Ph. edulis to access the quality and palatability. The results are as follows. 1. The length of Ph. prominens rhizome shoot was slightly longer; 2. The individual weight, shoot diameter and contents of protein, tan- nin, oxalic acid, total acid, cellulose, lignin of Ph. prominens rhizome shoot were significantly lower than that of the Ph. edulis ; 3. The edible rate, ratio of sugar to acid, contents of soluble sugar and fat of Ph. prominens rhizo- me shoot were obviously higher; 4. The content of total amino acid and its components except delicious amino acid in Ph. prominens rhizome shoot were dramatically lower, while the proportion of delicious, sweet and aromatic ami- no acid in Ph. prominens rhizome shoot were markedly higher than that of Ph. edulis ; 5. The bitter amino acid pro- portion in Ph. prominens rhizome shoot was significantly lower than that of Ph. edulis. All the results indicated that there were significantly differences on rhizome shoot quality and palatability between Ph. prominens and Ph. edulis. The rhizome shoot of Ph. prominens with high edible rate and low roughness was relatively larger and more palata- ble. Overall, the rhizome shoot quality of Ph. prom#tens was better than that of Ph. edulis.
