Özet: An experiment was performed to test the sensitivity of seed production and climatic conditions effect on mother plant. The seeds from different planting dates in field experiment were studied randomly in 2013 during four replications at the laboratory of Agriculture Faculty of Islamic Azad University, Khoy Branch. The results showed that the effect of sowing date on shoot length and dry weight, root germination, mean germination time, germination average, germination and mean germination were significant. Based on the results of the experiment, seeds from the first to third sowing dates had the best germination time and the average germination time for the best seedlings due to the highest length and stem and rootstock weight. In general, it became clear that the delay in planting the mother plant decreases seed quality. MGT indices showed a significant negative correlation with GR. Also, MDE increased the length and weight of the stem.
