| به منظور بررسی اثرات پرایمینگ اسمزی بر جوانه زنی بذر ذرت دو رگ سینگل کراس704 (K.SC 704)، آزمایشی به صورت فاکتوریل در قالب طرح پایه بلوک های کامل تصادفی با سه تکرار اجرا گردید. تیمارها شامل پرایمینگ بذر با محلول های پلی اتیلن گلایکول (PEG6000) با غلظت های 5 و 10 درصد، نیترات پتاسیم (KNO3) با غلظت های 1 و 2 درصد و کلرید پتاسیم (KCl) با غلظت های 2 و 4 درصد و مدت زمان های 8، 16 و 24 ساعت بودند. صفات اندازه گیری شده شامل طول ریشه چه و ساقه چه، سرعت جوانه زنی، وزن تر ریشه چه و ساقه چه، وزن خشک ریشه چه، نسبت وزن تر و خشک ریشه چه به ساقه چه، نسبت طولی ریشه چه به ساقه چه و تعداد گیاهچه عادی بودند. نتایج نشان داد که حداکثر طول ریشه چه و ساقه چه تحت تیمارهای زمان و پرایمینگ با پلی اتیلن گلایکول (PEG6000) با غلظت 5 درصد و زمان 16 ساعت بدست آمد، اما بیشترین نسبت طولی ریشه چه و ساقه چه (R/S ) و نسبت وزن تر ( R/S) با پیش تیمار پلی اتیلن گلایکول (PEG) و نیترات پتاسیم(KNO3) با غلظت های 5 و 2 درصد در مدت زمان 24 ساعت مشاهده شد. بیشترین سرعت جوانه زنی و وزن تر ریشه چه با پیش تیمار پلی اتیلن گلایکول (PEG) و نیترات پتاسیم ( KNO3) با غلظت های 5 و 2 درصد حاصل گردید. بنابراین بهترین پیش تیمار برای این تحقیق محلول پلی اتیلن گلایکول(PEG) با غلظت 5 درصد و با مدت زمان 16 ساعت پیشنهاد می گردد. | ||

| In order to study the effects of osmopriming on the germination of silage corn seeds (K.SC 704), a factorial experiment in a randomized completely block design with three replications was carried out in Qaemshahr faculty of agricultures lab in 2009. Factors included PEG with the density of 5 and 10%, KNO3 with the density of 1 and 2% and KCl 2 and 4% in the periods of 8, 16 and 24 hours. Primary root and length (mm), germination rate (Seed/day number), primary root and shoot tresh weight (gr), primary t root dry (gr) weight, primary root/ primary shoot length proportion (R/S), primary root/ primary shoot tresh weight proportion (R/S), primary root/ primary shoot dry weight proportion (R/S) and normal seedlings number were measured. The results indicated that the maximum length of root is obtained (R/S) under factors of time and priming PEG with the density of 5% and time of 16 hours, but the highest amount of length of roots and stems and wet weight (R/S) with prime by PEG and KNO3 with the density of 5 and 2% in the period of 24 hours was recorded. The highest rate of germination and wet weight of root with priming PEG and KNO3 was obtained with the density of 5 and 2%. | ||
