摘要

本試驗乃探討香水百合(Lilium oriental hybrid ”Casa Balanca”)經連續兩季接種四種不同叢枝內生菌根菌後，鱗莖的生長與磷含量的變化情形。在蛭石與珍珠石混合的介質中經第一季的生長，百合組培球分別接種四種不同菌根菌的處理，其生長勢皆較對照組差；但鱗莖內磷含量卻以接種Acaulospora scrobiculata的處理者為最高。第一季收穫後的鱗莖種植在相同的介質中，再經一季的生長後，發現接種A. scrobiculata和Glomus pansihalos菌根菌的香水百合的鱗莖周徑大小、株高等均顯著高於對照組。本研究指出菌根菌A. scrobiculata的接種，在第一季組培球的生長有助於鱗莖內磷含量的蓄積；而分離自鹼性土壤的菌根菌A. scrobiculata和G. pansihalos在鹼性介質中能有效促進百合鱗莖第二季的生長。

In this report, the inoculation effect of four different arbuscular Arbuscular mycorrhizal fungi (AMP) was recorded for two consecutive crop seasons, and was evaluated in terms of growth and the change of phosphorus content in oriental lily bulbs. At the first crop, all of the bulbs were cultivated in a mixed medium of vermiculite and pearlite, and the bulb growth in the four treatments of AMP was worse than control. However, the phosphorus content of bulbs in the treatment of A. scrobiculata was significantly higher than any other treatments. At the second growth season, the bulbs harvested from the first crop were cultivated in the same medium, and the treatments of A. scrobiculata and G. pansihalos came out significantly better than control based on the parameters of bulb perimeter, plant heights and so on. This study supports that the inoculation of A. scrobiculata is attributed to the nutrient accumulation, such as phosphorus in lily bulbs at 1(superscript st) crop. Besides, the species originally isolated from alkaline soil, such as A. scrobiculata and G. pansihalos proved their effectiveness in the growth promotion of lily bulbs at 2(superscript nd) crop under the alkaline growth medium.
