То the biology of some species of Lysimachia L. under the conditions of the culture

Results of introduced research of three beautiful-blossoming species of Lysimachia L. genus: L. clethroides Duby, L. punctata L L. ciliata L. are presented. Researches are conducted in the South Ural botanical garden-institute of UFRC RAS on the basis of a collection of shade-loving beautiful-blossoming and foliage plants in the following parameters: to a seasonal rhythm of development, biomorphological parameters, success of an introduction. Duration of blossoming of the studied species averages three weeks, except L. ciliata which blossoms more than a month. The studied species of Lysimachia under the conditions of Ufa do not form seeds, however actively breed in the vegetative way through formation of rhizomes. The studied species have high resistance to local climatic conditions, regularly and in large quantities blossom, well expand. Species of Lysimachia are perspective for culture and reproduction. They can be recommended for introduction in practice of gardening.

Foliage Plants Improve Concentration and Emotional Condition of Elementary School Students Performing an Intensive Assignment

This study was conducted to compare the concentration and emotional condition of elementary school students performing an intensive assignment in the presence or absence of foliage plants, using electroencephalography (EEG) and a modified semantic differential method (SDM). In a crossover experimental design, 30 elementary students performed a 3-min intensive age-appropriate arithmetic assignment in the presence or absence of foliage plants. Continuous EEG monitoring in the frontal lobe was performed using a wireless dry EEG device. Immediately thereafter, subjective evaluation of emotions was performed using the SDM. The concentration of the male elementary students was significantly higher when the assignment was performed in the presence vs. absence of plants as evidenced by the increase in the ratio of spectral edge frequency of 50 and a decrease in the relative theta power spectrum in the right frontal lobe. The SDM results revealed a significant psychological relaxation when the assignment was performed in the presence of plants. Therefore, the presence of foliage plants in the space where the elementary students performed the intensive assignment led to positive effects on concentration and emotional condition.

Community Empowerment About Utilizing Salak Parijotho Batik

This study aims to describe the empowerment of Sleman Salak Sinom Parijotho batik in terms of the use and preservation of the batikparijotho salak. This type of research is qualitative. Data in the study were obtained by observation, interviews, and documentation. The main instrument in the research is the researchers themselves with interview aids and documentation. The validity of the data is obtained by triangulation techniques, data analysis techniques by means of data reduction, data presentation, and drawing conclusions. The results of the study indicate whether the development of the batik parijotho had succeeded well in the community, as well as how much the community was interested in batik parijotho salak. And whether the preservation of batik Parijotho is well developed and useful not for the community. Can parijotho batik be superior in comparison to other batik and what is the superiority of this parijhoto batik. Sinom Parijotho Salak batik meaning is philosophical as the hope of prosperity and prosperity of the people of Sleman Regency. Parijotho salak batik is inspired by parijotho plants, which are foliage plants that grow in the mountains.

Real Foliage Plants as Visual Stimuli to Improve Concentration and Attention in Elementary Students

This study was conducted to determine the physiological and psychological benefits of foliage plants as visual stimuli. Twenty-three elementary students (aged 11 to 13 years old) participated in this study. In a crossover design, electroencephalography (EEG) was used to measure and determine the psycho-physiological effects of four different visual stimuli: an actual plant, artificial plant, photograph of a plant, and no plant. Subjective evaluations of emotions were assessed using the profile of mood state and semantic differential methods immediately after exposure to each visual stimulus. A significant decrease in theta waves of the frontal lobe was associated with presentation of the actual plants. This response indicated that the viewing of living plants prompted improvements in the attention and concentration of the elementary students. Furthermore, the presentation of the living plants was associated with more positive mood states, such as feelings of comfort and naturalness. In conclusion, actual plants may improve attention and prompt psychological relaxation in elementary students relative to artificial plants, photographs of plants, or the absence of plants.

Daily Evapotranspiration of Guzmania ‘Irene’ and Vriesea ‘Carly’ Bromeliads Produced in a Shaded Greenhouse

Bromeliads are important ornamental foliage plants, but until now, their daily water use during production was unknown. Using a canopy closure model developed for container-grown woody ornamental plants, in this study we investigated actual evapotranspiration (ETA) of Guzmania ‘Irene’ and Vriesea ‘Carly’ from tissue-cultured liners grown in 15-cm containers to marketable sizes in a shaded greenhouse. The mean daily ETA of Guzmania ‘Irene’ ranged from 4.02 to 66.35 mL per plant, and the mean cumulative ETA was 16.66 L over a 95-week production period. The mean daily ETA of Vriesea ‘Carly’ varied from 3.98 to 59.89 mL per plant, and the mean cumulative ETA was 15.52 L over the same production period as the Guzmania cultivar. The best-fit models for predicting daily ETA of the two bromeliads were developed, which had correlation coefficients (r2) of 0.79 for Guzmania ‘Irene’ and 0.68 for Vriesea ‘Carly’. The success in the model of ETA for both bromeliads suggested that the canopy closure model was equally applicable to container-grown ornamental foliage plants produced in greenhouse conditions. The daily ETA and cumulative ETA values represent research-based information on water requirements, and, when applied, could improve irrigation practices in bromeliad production. This study also showed that roots per se of the two epiphytic bromeliads were able to absorb water and nutrients from a peat-based container substrate and support their complete life cycles.
