abstract the cr(iii) and zn(ii) complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl)benzoic acid as ligand have been prepared by reacting cr(no3) and zn(no3)2 and ligand in cloroform. the cr and zn complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl) were also prepared in chloroform and aceton solutions. the uv-visible and ft-ir spectra of...
The present study was conducted to induce callus from different in vitro grown seedling explants of shoot, root and leaf segments in order to develop shoot buds and rooting from callus. The sterilized seeds were cultured on Murashige and Skoog medium, and then the explants were cultured from seedling and transferred to an MS medium supplemented with different concentrations of BAP, kinetin, NAA...
Synthetic seeds - A novel approach for the conservation of endangered C. spiralis wt. and C. pusilla
In the present study best suitable explant for encapsulation and effect of nutrient composition of alginate matrix on regrowth performance of encapsulated explants of endangered C. spiralis and C. pusilla were studied. Among all the explants tested, good sprouting frequency was observed with shoot tips in both the species. Where as, multiple shoot induction with maximum shoot length was noticed...
In micropropagation of Anthurium the most important and sensitive stage, is callus induction from explant. This experiment was conducted in a completely randomized design with factorial arrangement in 4 replications in Sari Agriculture Sciences and Natural Resources University (SANRU) in 2010. The cultivar used in this study is Fire and leaf segments with and without main nervure, were used as ...
Pith tissue from Nicotiana tabacum L. cv ;Maryland Mammoth' or ;Wisconsin 38' was isolated, free of vascular tissue, and cultured on a medium containing auxin but no cytokinin. Explants from the apical 1 cm of stem, within the pith rib meristem, initiated callus growth with 100% efficiency. Macroscopically visible callus was evident 5 days after the tissue was isolated, and the cultures grew pe...
This study surveyed a rapid, efficient and reproducible protocol for in vitro shoot regeneration and rooting by different explants and different concentration of BAP. Due to optimization of shoot regeneration, two media including of MS and modified MS (MS salts with double concentration of CaC21, and B5 vitamins), different explants such as decapitated embryo axes, epicotyls and cotyledonary no...
This paper describes a prime and easy-touse protocol for large-scale production of plant lets through shoot tip culture of Lantana camera, the plant having phytoremediation potential and the method is useful for the ex-situ conservation of other species important for phytoremediation. A simple micro-propagation method from nodal and shoot tip explants were reported here for Lantana camera, at c...
An efficient and highly reproducible protocol for micropropagation of bird eye chilli Capsicum frutescens was attempted. Murashige and Skoog (MS) medium containing 0.5-3.0 mgl(-1) of 6-benzyladenine (BA), 2-isopentenyl adenine (2iP), kinetin and 0.5-2.0 mg l(-1) of indole-3-acetic acid (IAA), indole-3-butyric acid (IBA) along with 1 gl(-1) activated charcoal (AC) were used for shoot regeneratio...
this study attempts to investigate the effect of peers’ revision in comparison to that of the teacher, and whether peers’ comments and teachers’ comments facilitate students’ revision? if yes, which one is more effective? also attempts have been made to see which aspects of language are more highlighted by peers versus teachers when commenting. besides, it is investigating the student’s attitud...
چکیده در بخش اول این پروژه دو روش میکرواستخخرا به نامهای میکرواسخخرا امولسیونی با کمک اموا فراصتتتو 1 و میکرواستتتخخرا مای – مای با کمک هوا 2 ، به عنوان دو روش میکرواستتتخخرا بدون حلال پخشکننده 3 ، برای اسخخرا برخی هیتدروکربتنهای آروماتیتک حلقوی 4 از نمونتههای آبتی بهکار گرفخه و پارامخرهای موثری همچون نوع حلال اسختتتتخرا کننده، حجم حلال اسخخرا کننده، میزان نمک، زمان تابش اموا فراصتو ، تددا...
