هدف این مطالعه، توسعه ی ریشه زایی rumex crispus و بررسی اثرات هورمون های اکسین و سیتوکینین بر تشکیل ریشه های نابجا و فلاونوئیدها در شرایط in vitro در این گونه می باشد. جهت این مطالعه، برگ ها در محیط های کشت ms حاوی غلظت های مختلف اکسین ها و ترکیبی از اکسین و سیتوکینین کشت شدند. نتایج نشان داد که در ریشه زایی r. crispus، naa موثرتر از iaa می باشد. کاربرد kin در ترکیب با naa در محیط کشت، وزن تر ر...
1 In an asexually reproducing plant ( Potamogeton pectinatus L.) the competitive advantage of a larger propagule over a smaller one was determined by a single parameter ( α , the competitive asymmetry coefficient), independent of sowing density or average propagule size. Competitive advantage was determined by the relative size difference between propagules instead of their absolute difference....
The programs of managing waste materials in developing countries are often unsatisfactory and the unreasonable disposal of waste is a major issue in the worldwide. The main aim of the current study is to: Assess the applicability of Rumex crispus L. in removing heavy metals from the contaminated wastewater effluent form Pharmaceutical laboratories by bio-adsorption method. The dried R. crispus ...
Future climate change has been predicted to affect the potential distribution of plant species. However, only few studies have addressed how invasive species may respond to future climate change despite the known effects of plant species invasion on nutrient cycles, ecosystem functions, and agricultural yields. In this study, we predicted the potential distributions of two invasive species, Rum...
The marine world is incredibly rich in brilliant and intense colours. Photonic structures are found in many different species and provide extremely complex optical responses that cannot be achieved solely by pigments. In this study we examine the cuticular structure of the red alga Chondrus crispus (Irish Moss) using anatomical and optical approaches. We experimentally measure the optical respo...
