Melia azedarach is one of the broadleaved, perennial woody plant species and belongs to Meliaceae family. The plant is multipurpose and has few pests and diseases. Because of this reason, some of the plant parts may be used as plant protection agent. The plant can also become an invasive species under certain environmental factors whose growth demands must be known. One of the propagation methods of the plant is generative propagation and this study is aimed to find out seedling emergence ratio differences between sowed groups (fruit, endocarp and seed) under different water treatment durations as 1 day, 7 days and 14 days along, besides control (no water treatment) under non-sterile condition in laboratory before sowing in peat under greenhouse condition. At the end of the study, first and last emergence days (day and date), seedling emergence rate (%), shoot number per sowed part were revealed. Data showed that first seedling emergence days changed between 25-37 in seeds and 31-37 in endocarp in all water treatment and control. In fruits there is no emergence in control and first seedling emergence days changed between 53-78 in all water durations. Emergence ratios were very high with a ratio of 80-92,50% in endocarps, and very low with a ratio of 0-12.5% in fruits in all water treatments and control. According to the data this is emphasized that the planted parts (fruit, endocarp, seed) are more effective than water treatment in most parameters and the fruit pericarp has a strong emergence inhibiting and retarding effects on seedling emergence in Melia azedarach.
