| به منظور بررسی اثر پوشش بذر بر ویژگیهای وابسته به جوانهزنی بذرهای کاهو در شرایط تنش خشکی، پژوهشی به شکل فاکتوریل در قالب طرح کاملاً تصادفی در 4 تکرار در سال 1401 اجرا شد. تیمارهای آزمایش شامل پوششهای بذر[:C1بدون پوشش (شاهد)، :C2پوشش بذر با جیبرلین+کائولن، :C3پوشش بذر با جیبرلین+هیومیکاسید+کائولن، :C4پوشش بذر با جیبرلین+عناصرریز مغذی+کائولن، :C5پوشش بذر با جیبرلین+عناصردرشت مغذی+کائولن، :C6پوشش بذر با هیومیکاسید+ عناصردرشت مغذی+عناصر ریز مغذی+کائولن و :C7پوشش بذر با جیبرلین+ هیومیکاسید+ عناصردرشت مغذی+ ریز مغذی+کائولن ] ،تحت شرایط تنش خشکی [بدون تنش (شاهد)، 4/0˗ ، 8/0˗ مگاپاسکال ] مورد ارزیابی قرار گرفت. در شرایط تنش 8/0- مگاپاسگال فقط تیمارهای C2(16 درصد) و C3(8 درصد) جوانهزنی داشتند. در تنش 4/0- مگاپاسکال تیمارهای C1, C2, C3 به ترتیب در صفات درصد جوانهزنی (50/88، 75/61 و 50/27 ) سرعت جوانهزنی (46/6، 91/3 و 25/2) و شاخص بنیه بذر (28/130، 32/93 و 02/44) تفاوت معنیداری با یکدیگر و همچنین با شرایط بدون تنش (شاهد) داشتند؛ به طوری که بذر C1 (شاهد) در شرایط تنش خشکی 5/72 درصد و بذر C3، 5/11 درصد کاهش جوانهزنی را نسبت به شرایط بدون تنش داشت. پوشش C3 سبب بهبود صفت میانگین مدت زمان جوانهزنی نسبت به پوشش C1 (07/3) شد. نتایج آزمایش نشان داد که تنش خشکی با ایجاد محدودیت در جذب آب یک عامل محدودکننده در جوانهزنی بذر کاهو است و انجام برخی تیمارها مانند پوشش جیبرلین+کائولن و جیبرلین+کائولن+ هیومیکاسید سبب بهبود صفات مرتبط با جوانهزنی بذر کاهو می-شود. | ||

| To investigate the effect of seed coating on characteristics related to germination of lettuce seeds under drought stress conditions, a factorial experiment was conducted a completely randomized design with 4 replications during 2022. The experimental treatments include seed coating(C1:uncoated seeds (control), C2:seed coating with kaolin+gibberellin,C3:seed coating with kaolin+humic acid+gibberellin, C4:seed coating with gibberellin+micro elements+kaolin, C5:seed coating with gibberellin+ macro elements + kaolin, C6:seed coating with humic acid+micro+macro elements+ kaolin, C7:seed coating with gibberellin + humic acid+ micro + macro elements + kaolin and it was evaluated under three levels of drought stress(no stress(control),-0.4 MPa,- 0.8 MPa). In the stress condition of -0.8 MPa, only two treatments C2 (16%) and C3 (8%) had germination. In the stress of 0.4 MPa, treatments C1, C2, C3, respectively, in the characteristics of germination percentage (88.50, 61.75 and 27.50), germination speed (6.46, 3.91 and 2.25) and root index The seeds (130/28, 93/32 and 44/02) had significant differences with each other and also with non-stressed conditions (control); So that C1 seed (control) had 72.5% and C3 seed had 11.5% reduction in germination compared to non-stressed conditions. C3 coating improved the average germination time compared to C1 coating (3.07). The results of the experiment showed that drought stress is a limiting factor in the germination of lettuce seeds by limiting water absorption, and some treatments such as gibberellin+ kaolin coating and gibberellin+ kaolin+ humic acid improve the characteristics related to lettuce seed germination. | ||
