摘要

Many soils are deficient in available nutrients, especially phosphorus (P), and therefore require considerable fertilizer application in order to obtain optimum plant growth. However, as citrus is strongly mycorrhizal dependent it is important to usean inoculum for enhanced and healthy seedling growth; in addition, mycorrhiza can reduce the requirement of applied P fertilizers. In order to use the optimum P fertilizer level for mycorrhizal inoculation, research on P fertilizer concentrations is still required; hence, the aim of this work was to determine the role of mycorrhizal inoculation on citrus seedling growth at different P concentrations. Sterilized Menzilat series soil was treated with 0, 50,100, 200 and 400 mg P205 per kg soil. Fertilizerand sterilized soil were placed into 3.5 kg pots. Experiments were conducted over a period of five months, and plantheight, shoot diameter, shoot and root dry matter, mycorrhizal colonization, and tissue P and Zn concentration were determined. Plant growth and nutrient uptake in mycorrhizae-inoculated plants was significantly increased. As citrus seedlings are mycorrhizal dependent, under sterile and low fertile conditions plant growth was stunted and seedlings did not grow properly. Seedling length, stem diameter and percentages of root inoculation were investigated, along with mycorrhizal dependency. Seedlings inoculated with mycorrhiza were shown to be strongly mycorrhizal dependent. The mycorrhizal inoculum potential of the soil can influence plantroot growth, which primarily depends on suitable mycorrhizal partners.
