Abstract
We investigated the tolerance of two Asparagus (Asparagus officinalis L.) cultivars : diploid 'JG701' and tetraploid 'JGH', to autotoxicity in continuous cropping. The effects of root, foliage and rhizosphere soil extracts were tested on seed germination. Organic acids from rhizosphere soil were identified by HPLC. Results showed that plant fresh weight of two cultivars of asparagus decreased under replant system. However, root and shoot weights 'JGH' were higher than of 'JG701' after the second replanting. Soil extract of 'JGH' was less inhibitory to seed germination and radicle length than of 'JG701'. The tetraploid cultivar proved superior to the diploid in continuous cropping.
