“…f., popularly known as balsam, is an ornamental plant belonging to the plant family Balsaminaceae and is native to East Africa. This species is widely cultivated for its ornamental value in many parts of the world and has naturalized in many of these areas (Lim et al 2014). In addition to its ornamental value, the flowers of Impatiens walleriana are edible and the decoction prepared from the dried leaves and roots is used as an abortifacient (Kokwaro 2009).…”

“…In addition to its ornamental value, the flowers of Impatiens walleriana are edible and the decoction prepared from the dried leaves and roots is used as an abortifacient (Kokwaro 2009). I. walleriana could be propagated through seeds as well as foliar stem cuttings (Lim et al 2014). A previous study (Koide et al 1999) has shown that the AM fungus Rhizophagus intraradices (Glomus intraradices) could improve the growth of I. walleriana plants raised from seeds.…”

Microorganisms play an important role in the propagation and growth of plants. Propagation of plants through stem cuttings is a popular method widely practiced in horticulture and forestry. As the information on the interactive role of arbuscular mycorrhizal (AM) fungi and phosphate-solubilizing bacteria (PSB) in the regeneration and growth of clonally propagated plants is limited, we inoculated stem cuttings of Impatiens walleriana with Rhizophagus fasciculatus and Bacillus megaterium var. phosphaticum individually or in combination in an unsterile Alfisol field soil. The inoculated cuttings were harvested after 45 days of cultivation and various growth parameters and phosphorus (P) uptake were measured. Inoculation with the AM fungus or PSB individually improved plant growth parameters, whereas the dual inoculation did not give synergistic results. Plants inoculated at cutting stage with R. fasciculatus accumulated the highest plant biomass and showed maximum microbial inoculation effect and efficiency of P uptake. Inoculation with the PSB stimulated symbiosis with native AM fungi but a synergistic effect has not been found when both AM fungi and PSB were co-inoculated. It could be concluded that screening for compatibility between microorganisms is essential before selecting the bioinoculants for dual inoculation.

Context: Plants of Impatiens genus are recognized source of extracts with antioxidant and antimicrobial activity, including I. balsamina (Sanskrit name: Tairini), a plant traditionally used in Asia to treat infections and inflammation. However, there is little information related to activities of whole plant extracts. Aim: To investigate the in vitro antioxidant and antimicrobial activities of the ethanolic extract from whole plant of I. balsamina, I. hawkeri and I. walleriana. Methods: Whole plant material of each species was macerated with ethanol (80% v/v). Phytochemical screening was applied for detection of different metabolites. Total phenolic content (TPC) and total flavonoids content (TFC) were determined using Folin-Ciocalteu and aluminum chloride methods respectively. In vitro antioxidant properties were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, potassium ferricyanide antioxidant reducing power (PFRAP) and oxygen radical absorbance capacity (ORAC) assays. In vitro antimicrobial activity of extracts was evaluated against Staphylococcus aureus (ATCC 29737), Staphylococcus epidermidis (ATCC 12228), Streptococcus pyogenes (ATCC 19615), Streptococcus pneumoniae (clinical isolate), Pseudomonas aeruginosa (ATCC 9027), Escherichia coli (ATCC 10536), Candida albicans (ATCC 10231) and Aspergillus niger (ATCC 16404) using microdilution assay for minimal inhibitory concentration (MIC) assessment. Statistical Analysis Used: Results were expressed as mean ± SD. Data obtained were analyzed statistically using ANOVA (one-way) followed by Tukey's post hoc test. Correlation analyses were performed using Pearson correlation test. Results: I. hawkeri extract showed the highest phenolic content (TPC: 44.04 mg GAE/g; TFC: 55, 02 mg QE/g) and was the most antioxidant extract. I. balsamina extract was the most active against all Gram positive bacteria (MIC: 2.5-10 mg/ml) tested and over C. albicans (MIC: 10 mg/ml). This extract also showed the widest antimicrobial spectrum. Conclusions: The evaluated Impatiens whole plant extracts are also promising sources of antioxidant and antimicrobial agents.
