In thе prеsent studу, a simрle protосоl for in vitro rooting induction of the important medicinal plant Coleus forskohlii Briq with high content secondary metabolites antioxidant activity was described. For germination seeds C. were placed on MS medium suррlemented 0.4 mg L-1 gibberellic acid and 1.0 CaCl2. The оbtаinеd shoots cultured half-strength ½ containing indole-3-butyric (IBA) or indole...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
The present study was carried out to investigate micropropagation possibility and determine the optimal medium composition and plant growth regulators (PGRs) combinations under in vitro conditions. The cotyledon and epicotyl explants obtained from 1 month old in vitro grown seedlings were used in MS medium containing BA (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) and TDZ (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) e...
Knowledge concerning in vitro regeneration and developmental responses of Abelmoschus moschatus Medik. L. (muskdana plant) is limited. Aseptic seedlings were successfully raised on Murashige and Skoog (MS) basal medium augmented with GA (0.5 mg L ). The seeds did not germinate on MS medium alone. 3 1 Cotyledonary Node (CN) gave the best response with regard to induction of multiple shoots among...
in the present study, an efficient protocol has been developed for callus induction and production of ra in callus culture of satureja khuzistanica for the first time. in vitro callus induction was achieved from young shoot tip explants cultured on ms and b5 media supplemented with different concentrations of iba (0.1, 1.0, 2.0 and 5.0 mgl-1) solely or in combination with cytokinins bap and kin...
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...
A rapid in vitro propagation system has been established from mature shoot tip and nodal segments of ahighly valuable medicinal plant Alternanthera sessilis (L.). The explants were cultured on Murashige andSkoog’s medium augmented with different concentrations and combinations of plant growth regulators forshoot bud initiation and multiplications. For shoot tip, highest freque...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
Shoots of apple rootstocks raised in vitro were transferred to various rooting media to study the effect of different factors on root initiation and development. Various concentrations of indole-3-butyric acid (IBA) initiated rooting but maximum rooting percentage was found with 2.0 and 2.5 mg l(-1) of IBA in M7 and with 1.0 mg l(-1) of IBA in MM106. The drawback was that the roots were thick, ...
