THE GROWTH OF MYCORRHIZAL AND NON-MYCORRHIZAL FORSYTHIA X INTERMEDIA ZAB. PLANTS UNDER DIFFERENT CLIMATE AND IN VARIOUS GROWING MEDIUM

Water matter and aridity has started getting a big threat for the plants even excluding in the problematic areas by resulting of global warming and significant air temperature increase in summer at the present time. As a result the plant development slows down, the nutrition relations are affected negatively, plants remain weak, they cannot give the desired effect and in some cases death occurs. In planting studies that will be made in such problematic areas, mycorrhizal plants are used in order to minimize the problems. The aim of this study is to investigate the difference between the growths of plants with and without mycorrhiza in vegetation studies that will be made in arid regions. For this purpose, mycorrhiza effects are experienced on Forsythia x intermedia plants which are preferred at landscape architecture designs because of its common existence in dense-massive vegetative designs and their functional and esthetic properties. Mycorrhizal and non-mycorrhizal Forsythia x intermedia saplings were planted in S, SS, SSO medium at three test areas with different annual rainfall values. By taking measurements once in every three months; the root length, number of shoots and distance between nodes were determined. Key Terms: Vesicular-Arbuscular Mycorrhiza, Forsythia x intermedia, drought stress, plant growing
