Effects of arbuscular mycorrhizal fungi in melon seedling under salt and deficit irrigation stress
2016
Guldigen, O.
The study was conducted to determine the effects of Arbuscular Mycorrhizal Fungus (AMF) applications on melon seedling development and tolerance levels to salinity and deficit irrigation stress conditions. Napolyon F1 cultivated commonly in the Lake Van Basin was used as plant material and two different mycorrhizas [Glomus intraradices and Commercial AMF (Glomus spp.)] were applied. Two separate experiments [The limited irrigation experiment (four applications of water constraints; 0%, 20%, 60% and 80%) and the salinity experiment (four applications of salt 0 mM, 50 mM, 100 mM and 150 mM)] were applied on the seedlings grown on pots containing 2:1 peat and perlite. Parameters such as plant growth parameters, leaf water content, membran injury index, macro-micro nutrient uptake and AMF root colonization were investigated.At the end of the experiment, it was determinated that AMF applications increased the tolerance levels of stress applied melon seedlings. AMF positively influenced seedling growth parameter and increased nutrient uptake; Moreover, AMF decreased mechanical and metabolic injuries on stress induced seedlings. In irrigation experiment, K0 and K1 applications having 100% irrigation and 80% had the best results and the applications having 60% water deficit had the highest AMF root colonization. In salinity application, plants could not have tolerance to T3 applications (150 mM). The results show that AMF have given positive results in melon seedlings and could be an alternative solution against environmental stresses.
