چکیده

اهداف: این پژوهش به منظور بررسی تاثیر تیمارهای مختلف شکست خواب بذر و بهبود جوانه زنی بذرهای گیاه کور (Capparis spinosa L.) انجام گردید.
مواد و روش ها: آزمایش در قالب طرح کاملا تصادفی در دانشگاه تبریز در سال 1398 اجرا گردید. تیمارهای مورد استفاده در این آزمایش شامل تیمار شاهد، تیمار آبشویی در دمای 40 درجه سانتیگراد به مدت 12 ساعت، تیمار خراش دهی مکانیکی(پوسته چینی بذر) و تیمار سرمادهی( در دو سطح سرمایی دوهفته ویک‌ماه) در محدوده دمایی 5-4 درجه سانتیگراد بود که در ترکیب های تیماری مختلف در شرایط آزمایشگاه بر روی بذرهای گیاه کور اعمال شد.
یافته ‌ها : صفت ‌های درصد جوانه ‌زنی، سرعت جوانه زنی بذر، شاخص بنیه بذر، طول ریشه چه و ساقه چه، طول گیاهچه، میانگین روز تا جوانه زنی، و میانگین روز ظهور برگ‌ در سطح آماری یک درصد تحت تاثیر تیمارهای مورد استفاده قرار گرفتند. بیشترین درصد جوانه زنی (80درصد) با تیمار تلفیقی سرمادهی یک ماه به همراه پوسته چینی حاصل گردید که به عنوان بهترین تیمار جوانه زنی معرفی میگردد

چکیده [English]

Background and Objective: The aim of this study was to investigate the effect of different treatments of seed dormancy failure and improved germination of Caper seeds (Capparis spinosa L.).
Materials and Methods: The experiment was conducted in the form of a completely randomized design at the University of Tabriz in 1398. The treatments used in this experiment include leaching treatment at 40 ° C for 12 hours, scarification treatment and chilling treatment (in a cool (4-5⸰C) and wet place for two weeks and one months). It was applied to Caper plant seeds in different treatment combinations in laboratory conditions.
Results: characteristics such as germination percentage, seed vigor index, seed germination rate, first day of germination, plant height and leaf emergence time were recorded and compared in each treatment. All characteristics were statistically significant at the level of one percent. The best treatment in all germination and growth characteristics of the plant was combined treatment of one month cold with seed scarification.
Conclusion: In general, The Mechanical scarification of seeds with combined treatment of one month cold has a more favorable effect than treatments with two weeks and without seed scratching. Therefore, increasing the cooling time had a positive effect on this experiment. Increasing the cooling time is more effective in eliminating seed dormancy and germination rate, and also seed leaching increases plants height.
