| جایگزین کردن علفکشهای بیولوژیکی به جای علفکشهای شیمیایی نه تنها اثرات سوء زیست محیطی را نداشته بلکه دارای مزیت زیست تخریبپذیری نیز میباشد. در این پژوهش عصاره چاودار (Secale cereale L.) در پلیمر زیستسازگار کیتوزان/آلژینات کپسوله و اثرات آن به همراه عصاره نانو کپسوله نشده روی خرفه Portulaca oleracea L.))، سس(Cuscuta campestris Y.(dodder)) مورد بررسی قرار گرفت. آزمایش به صورت فاکتوریل در قالب طرح کاملاً تصادفی انجام شد. عصاره حاصل از اندام هوایی و ریشه در غلظت های مختلف (0، 25/6 ، 5/12 ، 25، 50 و 100 درصد) بر صفات درصد جوانهزنی، سرعت جوانهزنی، طول و وزن تر ریشهچه و ساقهچه مورد ارزیابی قرار گرفتند. نتایج نشان داد که ذرات نسبتاً کروی با سطح صاف و دربردارنده عصاره بودند که اندازه ذرات نمونه عصاره نانو شده ساقه و ریشه به ترتیب بین 113 تا 350 نانومتر و بین 4/71 تا 129 نانومتر بود. عصاره نانو شده اندام هوایی و ریشه با غلظتهای 25، 50 و 100 درصد درصد جوانهزنی بذر سس را به صفر رساندند. بیشترین میزان جوانهزنی بذر خرفه مربوط به تیمار شاهد با میانگین 26/78 درصد بود که با سایر سطوح تیماری تفاوت معنیداری داشت. عصاره نانو اندام هوایی و ریشه با غلظتهای 25، 50 و 100 درصد موجب بازداری کامل از جوانهزنی بذر گیاه خرفه شدند که با سایر سطوح تیماری تفاوت معنیداری داشتند. با افزایش غلظت عصاره چاودار درصد بازدارندگی صفات مورد بررسی افزایش یافت و نانو کپسوله کردن باعث افزایش اثر اللوپاتیک عصاره چاودار شد. | ||

| چکیده [English] | ||
| Replacing biological herbicides instead of chemical herbicides has not only had adverse environmental effects but also has the advantage of biodegradability. In this study, the effect of rye extract in biocompatible polymer chitosan / alginate nanocapsule with non nonocapsulated extract on dodder and purslane were investigated. The experiment was conducted in a completely randomized design with factorial arrangement. Extracts of shoot and root were evaluated at different concentrations (0, 6.25, 12.5, 25, 50 and 100%) on germination percentage, germination rate, radicle and plumule length, radicle and plumule fresh weight. The results showed that the particles were relatively spherical with a smooth surface and the shoot and root extracts had particle sizes of 113 and 350 nm and 71.4 to 129 nm, respectively. Nano-extract of shoot and root reduced germination of sauces seed to zero at concentrations of 25, 50 and 100%. The highest germination percentage of purslane seed belonged to control treatment (78.26%) which was significantly different from other treatments. Shoot and root nano extracts caused complete inhibition of purslane seed germination at concentrations of 25, 50 and 100%, which were significantly different from other treatments. Increasing concentration of rye extract increased the inhibition percentage of studied traits and nanocapsulation increased allelopathic effect of rye extract. | ||
