چکیده مقاله :
به منظور بررسی تاثیر تنش شوری بر برخی شاخص های جوانه زنی و رشد گیاهچه گلرنگ آزمایشی به صورت فاکتوریل در قالب طرح کامل تصادفی با 4 تکرار در سال 1390 درگلخانه کشاورزی دانشگاه پیام نور ارومیه به اجرا در آمد. تیمارهای آزمایش شامل 4 هیبرید زرقان 279، گلدشت، فرامان و پدیده و سطوح شوری 0، 4، 8، 12 و 16 دسی زیمنس بر متر محلول کلرید سدیم بودند. در این تحقیق صفات وزن خشک ریشه، ساقه، برگ، اندام های هوایی، گیاهچه، طول ریشه، ساقه و شاخص مقاومت به تنش شوری اندازه گیری شدند. نتایج تجزیه واریانس نشان داد که سطوح مختلف شوری اثر بسیار معنی داری بر وزن خشک ریشه، وزن خشک برگ، وزن خشک ساقه، وزن خشک اندام های هوایی، وزن خشک گیاهچه، طول ساقه، طول ریشه، شاخص مقاومت به شوری داشت. مقایسه میانگین نشان داد که سطح شوری 16 دسی زیمنس بر متر صفات وزن خشک ریشه، وزن خشک برگ، وزن خشک ساقه، وزن خشک گیاهچه، طول ساقه و طول ریشه را به ترتیب به میزان 60، 44، 68، 55، 76 و 58 % نسبت به شاهد کاهش داد به طوری که بالاترین مقدار هریک از صفات فوق از تیمار شاهد و کمترین مقدار از سطح شوری 16 دسی زیمنس بر متر بدست آمد. ارقام مختلف نیز در سطوح شوری مختلف، پاسخ های متفاوتی از خود نشان دادند و مقاومت های متفاوتی داشتند. هیبرید فرامان نسبت به شوری تحمل بیشتری داشته و ارقام زرقان 279، گلدشت و پدیده ارقام حساس به شوری می باشند.
In order to investigation of salinity stress effects on vegetative, and plantlet growth an experiment conducted by factorial based on randomized completely block designs with 4 replications in 2011 in department of agriculture of Urmia Payame Noor. The factors were 4 genotypes (Zarghan 279, Gholdasht, Faraman and Padideh) and 5 level of salinity (0-4-8-12-16) ds/m from Nacl. In these research traits of root, leaf, stem dry weight, seedling dry weight, stem length, root length and stress tolerance index were meausured. The results showed that different levels of salinity had siugnificantly affect on root, leaf, stem dry weight, seedling dry weight, stem length, root length and stress tolerance index. Comparison of mean showed that salinity stress of 16 ds/m traits root, leaf, stem dry weight, seedling dry weight, stem length and root length decreased about 60, 44, 68, 55, 76 and 58%, respectively. So the highest obtained from control treatment and the lowest obtained from salinity level of 16 ds/m. The genotypes respond differently to salinity levels. It seems genotypes of Faraman have more tolerance to salinity conditions. Genotypes of Zarghan 279, Gholdasht and Padideh were sensitive to salinity stress.
