    摘要:

    研究了不同體積分?jǐn)?shù)1MCP處理對(duì)常溫和低溫貯藏期間脫殼茭白木纖化以及細(xì)胞超微 結(jié)構(gòu)的影響,。結(jié)果發(fā)現(xiàn):05μL/L的1MCP處理可較好保持常溫和低溫條件下茭 肉的外觀品質(zhì),抑制乙烯的產(chǎn)生,,減少纖維素含量的增加,,抑制可溶性果膠含量的下降和原 果膠含量的增加,減輕茭肉木纖化過程,。用透射電鏡觀察常溫貯藏6d后的茭肉超微結(jié)構(gòu),, 發(fā)現(xiàn)1MCP處理的細(xì)胞較對(duì)照細(xì)胞內(nèi)含物豐富,胞間連絲仍然清晰,,證實(shí)了1MCP處 理可延緩脫殼茭白的衰老過程,。

    Abstract:

    The effect of 1MCP treatments on lignification and cell ultrastructure of peeled water bamboo shoot was investigated under th e storage conditions of normal and low temperature. The results indicated that 0 5μL/L of 1MCP treatment could keep good sensory quality and inhibit t he ethylene production rate. It could also markedly reduce the increase of cellu lose content, the decrease of water soluble pectin content, and the increase of protopectin content, and inhibit the lignification of peeled water bamboo shoot. Transmission electron microscope was used to observe the ultrastructure of peel ed water bamboo under the storage conditions of normal temperature. The results showed that the cell inclusions of peeled water bamboo shoot treated with 1MCP were rich and the degradation of plasmodesma was inhibited compared with t h e control, which further indicated the inhibition of 1MCP on lignificati on of peeled water bamboo shoot. 
