| هدف از این تحقیق تعیین میزان تاثیر نانوذرات رس در پلیمر مصنوعی رزین آکریلیک، بر جوانهزنی و برخی خصوصیات دو گیاه قرهداغوعجوه بود که بدین منظور بذر دو گیاه از ایستگاه تثبیت شن کاظم آباد واقع در 15 کیلومتری شهرستان بردسکن در استان خراسان رضوی تهیه شد. آزمایشها به صورت طرح کاملا تصادفی با سه تیمار و چهار تکرار انجام شد. بدین منظور بذرها در داخل پتری دیش و همچنین مزرعه در معرض پلیمر مصنوعی رزین آکریلیک با یک و همچنین سه درصد نانوذرات رس قرار گرفتند. آب مقطر نیز به عنوان تیمار شاهد در نظر گرفته شد. درصد جوانهزنی روزانه و نهایی بذرها ثبت و سرعت جوانهزنی، میانگین زمان جوانهزنی، طول ساقه و ریشه، وزن‌تر و خشک ساقهچه و ریشه‌چه و شاخص بنیه بذر محاسبه شد. همچنین ابعاد گیاهان کاشته شده در مزرعه در هر تیمار و تعداد برگ هر کدام، 4 ماه پس از کشت مورد اندازهگیری قرار گرفت. نتایج نشان دهنده اختلاف معنی‌دار بین همه فاکتورهای مورد بررسی در هر دو گونه، بجز اختلاف سرعت جوانهزنی و میانگین زمان جوانهزنی که فقط در مورد گونه Nitraria schoberi مشاهده شد میباشد. به عنوان مثال، درصد جوانهزنی قرهداغ در تیمار پلیمر رزین آکریلیک حاوی یک درصد نانو رس(75/51%) نسبت به سایر تیمارها بیشتر بود، در حالی که در مورد عجوه بیشترین جوانهزنی متعلق به پلیمر حاوی سه درصد نانو رس (62/65%) بود. در مورد رشد گیاه، علیرغم اینکه تیمارهای مختلف تاثیرات متفاوتی بر گیاهان داشتند، کاربرد پلیمر و نانوذرات باعث افزایش طول ساقه و ریشه در هر دو گیاه شد. با در نظر گرفتن شرایط متفاوت گیاهان در طبیعت، کاربرد مالچهای نانوپلیمری جهت بهبود خصوصیات جوانهزنی و رویشی گیاهان توصیه میشود. | ||

| The purpose of this study was to investigate the effect of clay nanoparticles in synthetic polymeric resinson germination and some charachteristics of Nitraria schoberi and Halothamnus glaucus. Seeds of two plants collected from sand consolidated station located in Razavi Khorasan Province, Bardaskan city, Kazem Abad village. Experiments were carried on in completely Randomized Design with three treatment and four replications. For this purpose, seeds were subjected to synthetic polymeric resins with one and three percent of clay nanoparticles in petri dish and field condition. Distilled water was considered as the control treatment. Daily and final germination percentages were recorded and germination rate, mean germination time, shoot and root length, shootlet fresh and dry weigh, rootlet fresh and dry weight, and vigor index was calculated. After 4 months from cultivation, the size of cultivated plants and the number of leaves from each treatment was also measured. The results indicated that there was a significant difference between all the studied factors of both species except germination rate and mean germination time, which was observed just in Nitraria schoberi. For example, the highest germination percentage of Nitraria schoberi in acrylic resin polymer containing 1% nano clay (51.75%) was higher than other treatments, whereas the highest germination percentage of Halothamnus glaucus belonged to polymer containing 3% nano clay (65.62%). About the plant growth, despite the different effects of various treatments on cultivated species, application of polymer and nano-particles led to increasing the length of shoot and root of both plants. Considering the different conditions of plants in nature, the use of nanopolymer mulches to improve the germination and vegetative properties of plants is recommended. | ||
