چکیده

نوع جمیعت، اقلیم و تراکم روی خصوصیات مختلف گیاه دارویی ماریتیغال تأثیر به‌سزایی دارند. از این‌رو تاثیر دو اقلیم معتدل و سردسیر بر چهار جمیعت بومی جمع آوری شده از شوش، پل‌دختر، خرم‌آباد، الشتر و یک رقم زراعی به‌صورت طرح بلوک‌های کامل تصادفی در چند سال و چند مکان مورد ارزیابی قرار گرفت. همچنین آزمایشی در قالب طرح کرت‌های خرد شده شامل سه تراکم 6، 8 و10 بوته در مترمربع به عنوان کرت فرعی و جمیعت‌های ماریتیغال به عنوان کرت اصلی به مدت دو سال ۱۳۹4-1393 مورد ارزیابی قرار گرفت. نتایج نشان داد اقلیم تاثیر معنی‌داری بر ارتفاع بوته، عملکرد دانه و میزان ماده موثره سیلی‌بین داشت. اثرات متقابل منطقه کاشت و جمیعت نشان داد بیشترین میزان سیلی‌مارین (21 میلی گرم در گرم وزن خشک دانه) و سیلی‌بین (2/4 میلی گرم در گرم وزن خشک دانه) در جمیعت بومی الشتر و در اقلیم سردسیر الشتر به‌دست آمد. همچنین بیشترین ارتفاع بوته، عملکرد دانه و بیولوژیک از تراکم 8 بوته در مترمربع به‌دست آمد، ولی تراکم تاثیری بر میزان ماده موثره سیلی‌مارین نداشت.

چکیده [English]

The kind of population, climate and density have a significant influence on the various properties of the Milk Thistle. Therefore, the impact of two temperate and cold climate on the four native populations collected from Shush, Poldoktar, Khorramabad and Aleshtar and a cultivar were evaluated as a randomized complete block design in a few years and places. As Well as an experimental was performed in the form of Split plot includes three different densities of 6, 8 and 10 plants/m2 as subplots and populations of Milk Thistle as main plots for two years from 2014-2015. The results showed that the climate had significant impact on traits such as plant height, grain yield and Silybin. Results of the interaction effects showed that The maximum amount of Silymarin (21 mg.g) and Silybin (4.2 mg.g) was obtained in native population of Aleshtar and in the cold region. Also the highest of plant height, grain and biological yield was obtained at density of 8 plants/m2 but the density did not affect on the amount of Silymarin.
