摘要: 采用湿润好气培养法,研究连作西瓜植株残体根、茎、叶腐解过程产生的自毒物质-酚酸化合物的动态变化。结果表明,西瓜根、茎、叶残体腐解过程中均含有香豆酸、香草酸、阿魏酸等酚酸化合物。根和茎在腐解过程中产生的酚酸化合物主要是香豆酸和阿魏酸,叶片主要是香豆酸和苯丙烯酸。3种器官中酚酸化合物质总量表现为叶>;茎>;根。根、茎在腐解30 d时酚酸量达到高峰,叶在腐解20~30 d时酚酸量最高;到40~50 d时酚酸量很少,基本稳定。

Abstract: Variation of phenolic acids during decomposition of residuces of watermelon was studied by means ofmoist and aerobic cultivation. The results showed that watermelon residues of root, stem and leaf contained somekinds of phenolic acids such as p-coumaric, vanillic, ferulicacid. The contents of p-coumaric acid in root and stemwere the highest, and followed by that of ferulic acid. The content of p-coumaric acid in leaf was the highest, followed by that of cinnamic acid. The total phenolic acids contents are in a decreasing order, leaf, stem and root. Thetotal phenolic acids contained in the root and stem reached the maximum after 30 days of decomposition, while theleaf in 20 - 30 days. The total phenolic acids contents reached a stable and minimum state after 40 - 50 days.
