Abstract

To determine the influence of autotoxicity on natural regeneration of Cryptomeria fortunei，seed germination in water extract of C. fortunei litter was researched with treatments of 1 ∶ 10，1 ∶ 100，1 ∶ 200，and 1 ∶ 250 （litter water extract volume: distilled water volume）. Results showed that the high extract concentration（1 ∶ 10） restrained C. fortunei seed germination. Restraint intensity declined as the concentration decreased with a restraint intensity order of：undecomposed litter ＞ semi-decomposed litter ＞ soil. High performance liquid chromatograph（HPLC） was used to analyze autotoxins components of ferulic acid （FA），cinnamic acid （CA），and -hydroxybenzoic acid （-HA）. Also，autotoxin content identified in undecomposed litter was greater than semi-decomposed litter and soil combined. Thus，undecomposed litter was the primary source of released autotoxins.［Ch，2 fig. 4 tab. 22 ref.］
