Effects of certain mineral fertilizers on the biological mass of Indigofera Tinctoria and Impatiens Balsamina plants

The article describes the effect of mineral fertilizers on the cultivation of dyed Indigofera (Indigofera tinctoria L.) and henna (Impatiens balsamina L), the amount of their application and the ratio of basic nutrients (nitrogen, phosphorus and potassium) related. It has been established that the adequate development of Indigofera and henna plants depends on the ratio of mineral fertilizers used.

Potensi Daun Pacar Air (Impatiens balsamina L.) dalam Menghambat Pertumbuhan Jamur Rhizopus oryzae L.

Pacar air (Impatiens balsamina L.) plant belongs to the Balsaminaceae family and is used as an indigenous medicine in Asia for fingernail inflammation, fractures, and rheumatism treatments. Moreover, the antipruritic, antianaphylactic, antifungal, antibacterial, and antitumor activities of some compounds, especially phenolics and quinones from this plant have been studied extensively. Therefore, this study aims to determine the antifungal activity of Pacar air leaves (Impatiens balsamina L.) methanol extract against Rhizopus oryzae L. and the IC50 value. The results showed that an increase in the concentrations of I. balsamina L. leaves methanol extract significantly raised the fungal growth. Furthermore, the extract inhibition against R. oryzae L. at various concentrations of 0.5; 0.7; 0.9; 1.1; and 1.3% w/v were 10, 21.9, 58.06, 68.06, and 79.72%, respectively, while the IC50 value was 0.896%. Hence, the presence of naphthoquinones and other secondary metabolites are responsible for its antifungal activity. Based on these results, the antifungal potential of I. balsamina L. leaves against soft-rot fungi is useful in the future.

Uso de adubo de liberação lenta e convencional no cultivo de Impatiens balsamina

A Impatiens balsamina (beijo de frade, maria sem vergonha) é uma florífera ornamental, usada em vaso e para formação de canteiros; possui flores de cores vermelha, creme, laranja, rósea, branca, roxa ou mesclada, caule suculento e ereto, de altura variando entre 30 a 90 cm, sendo tipicamente tropical. A pesquisa foi realizada com o intuito de avaliar a produção I. balsamina (Blue Line Flores / Balsamina Camélia Sortida) com uso de adubo de liberação lenta e convencional, em casa de vegetação tipo PAD&FAN na UNESP /Ilha Solteira - SP. Jardineiras de polipropileno preto (47,5 cm x 17,5cm boca; 41,5cm x 113 cm fundo e 15,5 cm altura: 8,5 litros), foram preenchidas com os tratamentos: T1- Condicionador Floreira + Forth Plantio (13 – 5 – 13) (5 g L-1), T2 - Condicionador Floreira + Osmocote® 3M 14-14-14 (6 g L-1) e T3 - Condicionador Floreira + Osmocote® 3M 19-06-10 mini prill (6 g L-1), e posteriormente transplantadas 2 mudas (mudas com 30 dias). Conclui-se que os melhores resultados foram obtidos com uso de adubo de liberação lenta, com ênfase no tratamento T3 – Substato + Osmocote® 3M 19-06-10 mini prill (6 g L-1).

Optimasi formula sampo ekstrak daun pacar air (Impatiens balsamina L.) dengan kombinasi natrium lauril sulfat dan cocamide DEA

Dandruff is an anomalous condition characterized by excessive exfoliation of the horny layer from the scalp. The leaves of the water henna plant (Impatiens balsamina L.) are one of the natural ingredients that have anti-dandruff properties, so they can be used as an active ingredient in making dandruff shampoo. The water henna leaves were extracted using the maceration method with ethanol 96%. Apart from the active ingredients, shampoo also has an important component, namely surfactants. The surfactant used in this study was a combination of sodium lauryl sulfate and cocamide DEA. The purpose of this study was to optimize the surfactant formula of sodium lauryl sulfate and cocamide DEA in water henna leaf extract shampoo. This research was a laboratory experimental research. Formula optimization was done through the Simplex Latice Design (SLD) method approach by making eight formulas. All formulas were evaluated for their physical properties including the foam height test and pH test. The data obtained were processed with Design Expert® software. Based on the physical evaluation of the water henna leaf extract shampoo, the results of the high foam test were 10,025 cm and a pH of 6,12. The results of the acceptability test of shampoo preparations including the parameters of color, smell, texture and viscosity received a fairly good response with the acquisition of values 3,1, 3,3, 3,9 and 4 with information 1 (very dislike), 2 (dislike), 3 (quite like), 4 (like) and 5 (really like). The optimum formula for the shampoo consisting of 5% water henna leaf extract, 1,1863% sodium lauryl sulfate, 19,814% cocamide DEA, 3% CMC, 0,5% citric acid, 0,5% methyl paraben, 0,15% menthol and distilled water had physical properties that meet the requirements of a good shampoo preparation.

Growth Responses and Accumulation Characteristics of Three Ornamental Plants to Sn Contamination in Soil

Decorative ornamental plants have been applied as hyperaccumulators/phytoremediators to a wide spectrum of heavy metal contaminants. In this study, pot culture experiments were conducted to investigate the Sn tolerance and accumulation in Impatiens balsamina L., Mirabilis jalapa L. and Tagetes erecta L., in order to assess the possibility of these three ornamental plants to be used as phytoremediators of Sn-contaminated soil. Results show that all three plants exhibited strong tolerance to Sn contamination, and no significant visual toxicity was observed for all three plants grown under most of the Sn treatments. The amount of Sn accumulated in the three plants was positively correlated with the Sn concentration in the soil. The order of the Sn accumulative capacity was Impatiens balsamina > Mirabilis jalapa > Tagetes erecta. Impatiens balsamina and Tagetes erecta showed a low translocation ability (TF) (<1), and the roots accumulated the highest Sn concentration, but Impatiens balsamina showed a relatively high bioconcentration factor (BCF, Sn concentration in each part > 100 mg/kg after Sn treatment of 500 mg/kg). Meanwhile, the TF of Mirabilis jalapa was >1, and the fluorescence accumulated the most Sn. In combination with the adaptation to high concentrations of various heavy metals, these three ornamental plants are potential candidates for Sn mining tailings or contaminated soil.
