| چکیده | ||
| به منظور بررسی اثر هیدروپرایمینگ بر برخی خصوصیات جوانه زنی بذرهای چند شکل تاج الملوک زینتی این آزمایش به صورت فاکتوریل سه عامله در قالب طرح کاملا تصادفی به اجرا در آمد. در ابتدا بذرهای سیاه و قهوه ای رنگ به صورت چشمی از یکدیگر جدا شدند و پس از آن با استفاده از روش بینایی ماشین از نظر اندازه به دو گروه تقسیم شدند. سپس برای تحریک جوانهزنی، بذرها به مدت 4 هفته در دمای 4 درجه سانتی گراد نگهداری شده و پس از آن تحت تیمارهای شاهد، 4، 8، 12 و 24 ساعت هیدروپرایمینگ قرار گرفتند. این آزمایش به صورت فاکتوریل سه فاکتوره و در قالب طرح کاملاً تصادفی به اجرا درآمد. فاکتورهای آزمایشی شامل رنگ بذر، اندازه بذر و هیدروپرایمینگ بودند. نتایج نشان داد که بذرهای بزرگ در مقایسه با بذرهای کوچک درصد جوانهزنی، سرعت جوانهزنی بیشتر و متوسط زمان جوانهزنی کمتری داشتند. علاوه بر این بذرهای سیاه رنگ نیز در مقایسه با بذرهای قهوه ای در ارتباط با صفات بیان شده تظاهرات بهتری را نشان دادند. همچنین بهترین خصوصیات مربوط به جوانهزنی در تیمارهای 12 و 24 ساعت هیدروپرایمینگ ثبت شد. در مجموع با توجه به الگوی غیر یکنواخت جوانهزنی این گیاه، استفاده از بذرهای سیاه رنگ بزرگ در شرایط هیدروپرایمینگ 12 ساعت می تواند جوانهزنی بهتری را به همراه داشته و برای تولید با عملکرد بهتر تاجالملوک زینتی توصیه می شود. | ||

| چکیده [English] | ||
| Regarding importance of homogenous germination and to accelerate this stage of Aquilegia chrysantha a study was conducted with purpose of identification of different morph of seeds of A. chrysantha. Therefore, first the black and brown seeds were separated visually and then divided in two groups in term of size using machine vision method. The seeds were stored for four weeks at 4ₒC inrder to stimulate germination and after that the treatments of 4, 8, 12, 24 hours of hydropriming and control were applied on the seeds. The study was factorial and conducted in a completely randomized design. The factors include color and size of seeds and also hydropriming treatments. The results showed that large seeds in comparison with small seeds were better in traits including seed germination percentage, germination rate, and mean germination time. In addition black seeds have a better performance in mentioned traits than brown seeds. Also the best characteristics of germination were recorded in the 12 and 24 hours of hydropriming. Overall, using large black seeds in the 12 hours of hydropriming would have a good germination and is recommended for better production of A. chrysantha. | ||
