囊叢枝菌根在滿天星栽培之研究

滿天星（Gypsophila paniculata L.）扦插育苗介質中以體積比1:20混合含內生菌根菌之阿泰母岩砂（attapulgite，含孢子數約每公克50粒），於接種四週後採滿天星根系，分別利用錐蟲藍（0.05% trypan blue）及酸性品紅（0.05% acid Fusin）染色法檢查菌根感染率，結果顯示以酸性品紅染色的效果較佳，可明顯觀察到菌根菌之孢子，而錐蟲藍染色的效果則不佳。由滿天星幼苗之生育性狀顯示，接種菌根菌處理可以增加滿天星幼苗全株乾重及根長。田間栽培結果顯示，接種菌根菌處理之滿天星切花產量及植株存活率等顯著地高於對照處理，且接種菌根菌處理具有提早及集中滿天星切花產期之功效。接種菌根菌處理配合不同磷肥用量之試驗結果顯示，磷肥用量減少50%與磷肥全量處理間之滿天星切花產量差異不顯著，顯然接種菌根菌處理可以配合降低磷肥用量。

This research was probed into the application of VAM fungus (Glomous spp.) on the production of baby's breath (Gypsophila paniculata L.). The seedling breeding medium and attapulgite was mixed by the ratio of 1:20 in volume, which gram attapulgite had contained 50 spores of VAM fungus. After 4 weeks when inoculated, cut down the root of seedling and used the trypan blue and fusin acid to stained for inspected the infection ratio of VAM fungus. From the result, we found the fusin acid had the better stained effect then trypan blue, it could clear identified the VAM fungus spores from the plant root tissue. From the growth data of baby's breath seedling, the seedlings that inoculated by VAM fungus could increased the root length and dry weight of the whole plant. In the field culture test, the plant that inoculated by VAM fungus could conspicuous increased the cut flowers product and survival ratio then non-inoculated. The other effect was advance the customary time and centralize the flower period. From the result of applicated different level phosphate fertilizer harmony with inoculated VAM fungus plant. The flower products of full phosphate fertilizer treatment had no-significantly different then half treatment. Therefore when inoculated VAM fungus on the baby's breath could decrease the applicated quality of phosphate fertilizer.
