摘  要:
[目的]研究低能离子注入对丛枝菌根真菌及其与蒺藜苜蓿共生的影响。[方法]以丛枝菌根真菌Arbuscular mycorrhizal fungi为试验材料,以豆科模式植物——蒺藜苜蓿为寄主,经低能离子注入后,考察丛枝菌根真菌的孢子萌发率和菌丝长度;然后建立蒺藜苜蓿与丛枝菌根真菌的共生关系,并对根的侵染、孢子产量以及根外菌丝的生长进行评估。[结果]低剂量的离子注入能刺激丛枝菌根真菌孢子的萌发和早期的生长;高剂量的离子注入则抑制丛枝菌根真菌孢子的萌发和早期的生长;在所选剂量范围内,离子注入不影响丛枝菌根真菌与蒺藜苜蓿建立共生关系。[结论]可以利用离子束生物技术对丛枝菌根真菌进行改良;该研究为提高豆科牧草抗逆性的研究提供了新思路和新方法。

摘  要:
[Objective]The aim of the study was set to investigate the effect of ion beam on arbuscular mycorrhizal fungi( AMF) and mycorrhizal Medicago truncatula.[Method]Taking Arbuscular mycorrhizal fungi and Legume model plant Medicago truncatula as test material and host respectively,after ion irradiation,spore germination rate and hyphal length of Arbuscular mycorrhizal fungi was studied,then Symbiotic relationship between Arbuscular mycorrhizal fungi and Medicago truncatula was established.Infection of root,spore production and growth of external hyphae were evaluated.[Result]The results showed that early germination and growth of AMF were significantly affected by ion beam irradiation. Low dose ion implantation promoted the development of AMF. High dose ion implantation inhibited the development of AMF. Ion implantation did not affect the symbiotic relationship between AMF and Medicago truncatula. [Conclusion]These results supported that ion beam implantation may serve as a powerful tool to improve AMF. This study provided new ideas and new methods to improve the stress resistance of leguminous forage.
