中文摘要 | 本試驗以‘屏東長茄’和‘麻芝茄’兩茄子品種於穴盤進行叢枝菌根菌(arbuscular mycorrhizal fungi;AMF)之接種,所採用的菌種包括繡球屬混合菌種(簡稱G. mix; 為Glomus mosseae (Nicol. & Gerd.) Gerd. & Trappe, Glomus fasciculatum (Thaxter sensu Gerd.) Gerd & Trappe and Glomus etunicatum Becker & Gerd.等三種菌種以相同孢子數混合)或大孢子屬Gigaspora gigantea (Nicol. & Gerd.) Gerd. & Trappe (簡稱為Gig.)的孢子土。結果顯示:(1)以72格穴盤,每格接種繡球屬混合菌種均含有約180粒孢子,即有50%感染率。而苗期的生長各處理間並沒有顯著的差異,顯示生長初期菌根感染率多寡與促進植物生長無直接相關。(2)介質種類採用BVB四號與蛭石1:1(v/v)之混合介質進行接種效果最好。(3)所採用不同濃度的強生溶液濃度,對穴植盤育苗植株之菌根感染率,沒有顯著的影響。(4)以繡球屬混合菌種或大孢子屬菌種所育成之菌根穴盤苗,種入田中後,皆可以使茄子提早開花,並顯著促進田間產量的增加,顯示茄子菌根穴盤苗有其經濟及應用上的價值。 |
英文摘要 | The response of three eggplant (Solanum melongena L.) culitivars (cv. ‘Pingtung Long’, Know-You Long and Extra Long) to the inoculation of arbuscular mycorrhizal fungi (AMF) in celled-plug system and their growth in field were intensively studied. It was found that in each 72 celled-plug, Glomus spp. mixed inoculum contained about 180 spores was inoculated to the middle layer of medium, which resulted in about 50% of mycorrhizal infection, but the seedlings growth did not show any significant difference between mycorrhizal and non-mycorrhizal control. A mixture of the BVB#4 : vermiculite=1:1 (v/v) provided the best seedling growth and higher mycorrhizal infection. Reducing the phosphorus concentrations of Johnson's solution had no effect on the formation of arbuscular-mycorrhizae in eggplant. The field trial results showed that the Glomus spp. or Gigaspora sp. infected mycorrhizal eggplant not only enchanced earlier flowering, but also increased fruit production than the non-mycorrhizal control. It was concluded that mycorrhizal eggplant seedlings showed great potential for practical use. |
