中文摘要 | 落花生接種內生菌根菌(Vascular Arbuscular Mycorrhizal Fungus, VAM)與根瘤細菌(Rhizobium)後對植物的生長、根瘤型成、磷含量及磷活性的影響研究以盆栽試驗測定之。處理包括單獨接種內生菌根菌(Glomus mosseae) (每盆約250spores)、根瘤細菌(Rhizobium sp.) (每盆約106 cells)、同時接種內生菌根菌與根瘤細菌、及均無接種者。所有實驗均在滅菌土壤(pH7.6)中進行,花生種子播種於含有接種源的六吋或九吋瓦缽中。實驗結果顯示,同時接種內生菌根菌與根瘤細菌的處理,其植株的生長、根瘤數目、內生菌根菌纏據情形,均比單獨接種的處理顯著為佳。而且,內生菌根菌+根瘤菌處理的植株體內的磷含量,以及酸性與鹼性磷酸酵素(acid, alkaline phosphatases)的活性亦增加,且顯著較單獨接種者與對照處理為高。本文同時討論試驗結果的顯著性。 |
英文摘要 | Influence of VAM fungus and Rhizobium inoculation on groundnut growth response in relation to growth, nodulation, phosphorus content and phosphatase activity was Studied in pot culture studies. The treatments consisted of inoculation with VAM fungus (Glomus mosseae) only, Rhizobium only, dual inoculation with VAM fungus and Rhizobium and control under sterilized soil conditions. Seeds of groundnut were seeded in 6"or 9"pots containing different inoculua, respectively. Concentration of VAM used as inoculum was 250 spores per pot, whereas Rhizobium was 106 Cells. Data were counted at the 15, 25, and 45th day after inoculation. Dual inoculation resulted in significant increase in growth, number of nodules, mycorrhizal colonization than inoculation with VAM fungusRhizobium alone. The amount of phosphorus and activity of acid and alkaline phosphatases increased significantly with dual inoculation than with individual inoculations. The significance of the results is discussed. |
