Arbuscular Mycorrhizal Fungi Affect Seedling Growth of Melon Hybrid Cultivars
(Friends Science Publ, 2013) Sensoy, Suat; Bicer, Seymus; Unsal, Husameddin
Hybrid melon cultivars (Super Magnum F-1, Extra Early Galia F-1, Rambo F-1 and Sempati F-1) were inoculated with 3 different AMF (Arbuscular Mycorrhizal Fungi) [Gigaspora margarita (Gm), Glomus intraradices (Gi), and G. etunicatum (Ge)] in order to examine the effects of AMF on seedling growth in melon. The seedling traits, nutrient uptake, colonization, and relative mycorrhizal dependency (RMD) were assessed in the experiment. Mycorrhizal colonization of melon cultivars ranged from 38.9 to 54.9%. The nitrogen, phosphorous, potassium, magnesium, and manganese contents were affected by melon cultivars, AMF, or their combinations. Relative mycorrhizal dependency also varied widely; only half of the melon cultivar-mycorrhizae combinations showed positive mycorrhizal dependencies. The Gi inoculations had higher positive RMDs, while the Gm inoculations had lower negative RMDs. (c) 2013 Friends Science Publishers

The effectiveness of different arbuscular mycorrhizal fungi (AMF) on different hybrid cucumber cultivars has not been well documented, even under normal seedling conditions. The present study therefore aimed to evaluate colonization, nutrient uptake, dependency, and other seedling traits of 4 cucumber hybrids (Ceren F-1, Beta F-1, Silyon F-1, and Maraton F-1) inoculated by 3 different AMF [Glomus intraradices (Gi), Glomus etunicatum (Ge) and Gigaspora margarita (Gm)]. Traits were evaluated in a growth chamber experiment consisting of a 4 x 4 factorial design (4 cucumber hybrids, 3 AMF plus 1 control) with 3 random replications. AMF-inoculated cucumber seedlings had shorter hypocotyledons and wider and longer cotyledons than non-inoculated seedlings. Gm-inoculated seedlings had the narrowest stem diameter and lowest leaf number. AMF-inoculated seedlings had shorter shoots and longer roots than noninoculated ones. There was significant mycorrhizal effect on the iron (Fe) content of shoots and the mycorrhizal colonization rate in roots. Relative mycorrhizal dependency (RMD) varied widely among the hybrid cucumber cultivars tested. It is thought that the determination of high-RMD cultivars could lead to improvements in cucumber seedling production in the future.
