Effect of Salinity on Morpho-Physiological Characteristics of Spring Wheat Genotypes

Contributors

Abstract

Bread wheat germplasm tolerant to salinity with high end-use quality is required to maintain grain production in saline lands. Four spring bread wheat cultivars with different tolerance to salinity and their three F3 progenies were evaluated at four levels of salt concentrations; 0, 150, 200 and 250 Mm NaCl. Na+, K+ and Cl- concentrations in the wheat penultimate leaf and some of the biomass and yield related traits were measured. The allelic variations of Glu-1 loci in the crosses were examined. Salinity had a significant positive effect on Na+ and Cl- concentrations and the Na+/K+ ratio. As salinity level increased, yield and 1000 grain weight and K+ concentration were declined. Most of the F3 progenies did not show much improvement in terms of biomass or yield related traits. However, F3 progenies of the Cajema×Lerma Rojo cross showed an improved quality score.

تاثیر شوری و تابش اشعه لیزر بر میزان تجمع پرولین در بذور گندم بهاره

Abstract [Persian]

یکی از محرک­های زیستی موثر روی گیاهان عالی، اشعه لیزر می­باشد. تاثیر مثبت تابش لیزر بر بعضی از گیاهان زراعی توسط محققان اثبات گردیده است. در تحقیق حاضر تاثیر تابش لیزر بر میزان تجمع پرولین در گندم بهاره کویر (Triticum aestivum cv. Kavir) تحت شرایط شوری مختلف بررسی گردید. در این تحقیق سه نوع نور لیزر تحت عنوان قرمز، مادون قرمز (که هر دو از لیزرهای نیمه رسانا یا دیودی هستند) و Nd:YAG (که از لیزرهای جامد می­باشد) به عنوان منابع تابش استفاده گردید. بذور برای مدت 12 دقیقه تحت تاثیر تابش قرار گرفتند و این تابش به صورت یک­بار و دوبار (هر بار 12 دقیقه) انجام شد و بذور تابش ندیده به عنوان شاهد مورد استفاده قرار گرفتند. این تحقیق به صورت فاکتوریل در قالب طرح کاملا تصادفی با سه تکرار اجرا گردید. نتایح به صورت معنی­دار بیانگر افزایش تجمع پرولین برگ­ها بعد از اعمال تابش لیزر و افزایش مقاومت به شوری بود. دوزهای مختلف تابش لیزر بر میزان تجمع پرولین تاثیر متفاوتی داشتند. بیشترین میزان تجمع پرولین در یک بار تابش به وسیله اشعه Nd:YAG مشاهده شد. مقاله حاضر نخستین گزارش مربوط به استفاده از انواع مختلف اشعه لیزر و تاثیر آن بر میزان پرولین در گندم بهاره است. نتایج بیانگر تاثیر مثبت تیمار لیزر در اصلاح صفت تحمل به شوری در گندم است.
