چکیده مقاله :
در این پژوهش اثر منبع جداکشت، تنظیم کننده‌های رشد و NaCl بر اندام‌زایی و تجمع پرولین در گیاه کهور از گونه‌ای بردبار به شوری مورد مطالعه قرار گرفته است. مریستم، برگ جوان ولپه از دانه‌رست‌های کشت شده در شیشه جدا شده است. سپس جدا کشت‌ها در محیط MS به اضافه تنظیم کننده‌های مختلف رشد کشت شدند. جداکشت‌های مریستمی چندین اندام هوایی و ریشه تولید نمودند. برعکس کالوس‌های برگی اندام هوایی و ریشه تولید نکردند. بهترین تیمار برای ایجاد اندام هوایی محیط کشت محتوی یک میلی‌گرم در لیتر بنزیل آمینوپورین و 1/0 میلی‌گرم در لیتر نفتالن استیک بود. اکسین تولید کالوس و ریشه را تحریک نمود، برعکس سیتوکینین تشکیل اندام هوایی را تسریع نمود. اثر غلظت‌های مختلف NaCl (0، 2، 4، 6، 8، 10گرم در لیتر) بر اندام‌زایی و تجمع پرولین نیز مورد بررسی قرار گرفت. نتایج نشان داد که شوری موجب کاهش اندام‌زایی شد، ولی اثر کمی در القاء کالوس داشته است. گرچه غلظت بالای شوری موجب بازدارندگی تشکیل کالوس و اندام‌زایی شد. محتوای پرولین بطور معنی‌داری با افزایش شوری افزایش یافت، ولی افزایش NaCl از 8 میلی‌گرم در لیتر تا 10 میلی‌گرم در لیتر محتوای پرولین را اضافه نکرد.
Effect of explants source, plant growth regulator and NaCl on organogenesis and proline accumulation in prosopis Kolziana, salt tolerant species, were studied. Meristem, young leaf, and cotyledon separated from in vitro seedling. Then explants were cultured on MS medium supplement with different plant growth regulators. Multiple shoot regeneration was observed in meristem explants. In contrast leaf callus did not produce any shoot and root. The best treatment for shoot regeneration was MS Medium containing 1 mgl-1 6-benzylaminopurine and 0.1 mgl-1 naphtalenacetic acid. Auxins promoted callus and root regeneration. In contrast cytokinin hormones induced shoot formation. Effect of different concentrations of NaCl (2, 4, 6, 8, 10 gl-1) on organogenesis and proline accumulation were investigated. The result showed salt stress tends to decrease of organogenesis. But it had less effect on callus induction. Although, high content of NaCl inhibited both callusing and shoot regeneration. Proline content was significantly increased by increasing the NaCl. Increasing the NaCl concentration from 8 mgl-1 to 12 mgl-1 did not enhance proline content. It is suggested proline had an important role on salt resistance in this species.
