STUDIES ON REPLANT PROBLEMS OF APPLE AND PEACH |

| Abstract:
The experiments were carried out with peach (Prunus persica L. Batch) and apple (Malus hupehensis Rehd.) seedlings planted in pots. The soils were collected from peach and apple nursery, respectively. Non inoculated seedlings grew poorly in autoclaved, formaldehyde and ozone treated, or unsterilized soils. Plants inoculated with Glomus spp. produced excellent growth in these treated soils. All mycorrhizal plants had a greater dry weight than non mycorrhizal plants. The results indicated that preplant sterilization and inoculation with vesicular - arbuscular mycorrhizal fungi may control the replant problem of horticultural crops. The combination of autoclaved soil and inoculation with VAM fungi was most effective. The treatments with 600 mgkg -1 and 100 mgkg -1 formaldehyde were moderately effective for peach and apple separately. Inoculation with mycorrhizal fungi in sterilized soils may limit the proliferation of nematodes. Soil treatment with formaldehyde is a promising measure in overcoming the replant problems of peach and apple. | |
