摘要

本試驗瞭解接種菌根菌對不同洋香瓜品種感染及苗期生育健化情形，洋香瓜穴盤菌根苗之田間栽培試驗，調查資料顯示接種菌根菌可促進洋香瓜生長勢與提昇果實糖度，惟產量與果實榨汁率則互有高低，其中一處接種菌根菌對產量有負面效果產生，可能因土壤養分產生拮抗性，導致葉片黃化，進而影響植株光合成產物產生。因叢枝菌根菌需宿主植物提供光合產物，故任何影響光合產物的因素自然也會影響叢枝菌根發展與功能，當土壤與施肥管理不當均會影響接種菌根菌植株之效益，另資料亦發現接種菌根菌可降低線蟲為害，接菌處理導致植株根圈附近線蟲蟲數降低，是否為接菌植株產生某些物質抑制線蟲繁殖或因接菌減少線蟲侵入為害阻斷其食物來源，機制有待進一步研究。

This experiment is attempted to evaluate inoculation of endomycorrhizal fungi Glomus spp. to the growth of muskmelon seedlings in the adoption period and its infection rate on different muskmelon varieties, as well as the growth of muskmelon plants after inoculation in field experiment. The investigation material demonstrated that the inoculant mycorrhiza may promote the muskmelon to live the growing trend and the promotion fruit soluble solids, only the output and the juice extraction ratios mutually to have the height. The inoculant mycorrhiza has the negative effect production, because possible the soil nutrient to produce oppresses the resistance, causes the leaf blade etiolution, then influence adult plant light synthetic product production. Because the fungus mycorrhiza needs the host plant to provide the photosynthesis product, therefore any influence photosynthesis product's factor will affect naturally also the clump of fungus root development and the function, when the soil with will apply fertilizer the management not when will affect benefit of the inoculant mycorrhiza adult plant. Another material also discovered that the inoculant mycorrhiza may reduce the wireworm to damage, meets fungus processing to cause nearby the adult plant root circle the insects mouth number to reduce, because whether to meet the fungus adult plant to produce certain materials to suppress the wireworm to reproduce or meets the fungus reduction wireworm invasion to damage blocks its food to originate, the mechanism waits for further studying.
