Plant growth regulators (PGRs) have an important role in callus induction and organogenesis of plant explants cultured in vitro conditions. Callus has a proper potential for plant regeneration through indirect organogenesis and embryogenesis as well suspension culture, genetic transformation and production of secondary metabolites. In current experiment, leaf explants of Petunia × hybrida F1 we...

We investigated the influence of different conditions (light composition and plant growth regulators (PGRs) in culture media) on morphophysiological parameters Stevia rebaudiana Bertoni vitro vivo. Both PGRs light spectra applied were found to significantly affect morphogenesis. During micropropagation stage S. rebaudiana, optimal growth, with a multiplication coefficient 15, was obtained an MS...

Here, efficient plantlet regeneration via somatic embryogenesis from Panax quinquefolium hairy roots was reported. Callus development was optimal on MS medium containing 2,4-dichlorophenoxyacetic acid (1 mg l) and -naphthalene acetic acid (1 mg l). After a 4-week growth, calli were transferred onto MS medium with different combinations of plant growth regulators (PGRs). The highest embryogenesi...

carbon and nitrogen are the two elements that most affect plant organogenesis. in vitro, usually as part of the macronutrients. some anecdotal evidence from the literature suggests that the ammonium (nh4+) to nitrate (no3–) ratio may affect orchid organogenesis. in this study, to test this hypothesis, different nh4+: no3– ratios were tested on the development of protocorm-like bodies (plbs) of ...

strawberry is a valuable, nutritious, and economically important fruit all over the world including bangladesh. therefore, there is a demand to develop a suitable variety of strawberry. for this purpose, leaf explants from in vitro grown strawberry plantlets were cultured onto ms medium supplemented with different concentrations and combinations of 2,4-d, naa and ba for callus induction. the mo...

Abstract Purpose In recent years, considerable research has been conducted on the use of plant growth regulators (PGRs) to improve crop yields. Large amounts PGRs are applied regulate growth. However, few studies have assessed impact PGRs, which leave soil residues, microorganisms, especially rhizobia. Methods this study, influence inoculation soybean roots with Sinorhizobium fredii and Bradyrh...

Thiocyanate (SCN?) present in irrigation water can have negative effects on plant growth and crop yields. Addition of regulators (PGRs) alleviate toxic stress to plants. In the current study, we established a grey situation decision-making model (GSDM) integrate data RT-qPCR analysis for screening optimal addition PGRs minimise pollution stress. The (i.e., jasmonic acid [JA], indole-3-acetic [I...

The use of plant growth regulators (PGRs) in cotton to control growth and enhance yield is a widely used practice. The most commonly used PGR to control vegetative growth is Pix® (mepiquat chloride). Recently, the bacterium Bacillus cereus was added to Pix to form Pix Plus, a new and improved version of Pix. Research results have shown that Pix Plus has a small yield advantage over Pix while st...

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...
