Specific horticulture therapy guidelines in the landscaping of Cluj-Napoca hospital facilities – improving mental and behavioural healthcare

Abstract In the beginning, nature was an irreplaceable environment for humans. The concept of horticulture therapy (HT) denotes the use of ornamental plants to improve people’s health based on the connection between landscape architecture principles, design elements, and guidelines in healthcare facility gardens. In HT, people can improve and maintain health; so, gardens must provide only beneficial effects for users (patient, family, staff), testing design elements, which can be a scroll direction in garden, point of interest, connection with nature. This paper presents a case study analysis of the current landscape architecture standpoint: one of the Cluj-Napoca clinics, where HT can improve patients’ well-being.

Research Concerning the Behavior of Sempervivum Plants under Treatements with Herbicides

The research conducted focused on determining the behavior of Sempervivum montanumplants when treated with herbicides. Six products were used with the following commercial names:Fusilade, Select, Pantera, Goal, Afalon Premiant. From each herbicide were prepared three solutionsof different concentrations (0.2%, 0.1%, 0.05%). With these solutions the Sempervivum montanumplants were sprayed. The effects on the plants were observed after 10-14 days. By determinations wasestablished the number of plants fatally affected, partially affected and unaffected. The research resultsshows that herbicides applied at a concentration of 0.2% are harmful to Sempervivum montanumplants, but in a very variable amount depending on the herbicide. The most powerful harmful effectswas observed in treatment with Goal herbicide. Definitive recommendations can not be made, for thisfurther research is required.

Solutions Concerning the Improvement of Multiplication Technology of Argyranthemum frutescens (L.) Sch. Bip

Argyranthemum frutescens (Chrysanthemum frutescens L.), the marguerite, is a perennial plant known for its flowers. It is native to the Canary Islands, their native habitat ranges from the seashore, woodland edges and slopes of volcanic mountains. Marguerites have been grown for more than 200 years, with more than 80 types now available (most of them are hybrids). The aim of the research was to improve the current assortment of floricultural plants in Romania, with new varieties of ornamental species with different morphological characteristics, to be promoted and placed in production. Along with taking the study of new varieties, it has studying the improvement of the culture technology, too. In the present paper, we made some research’s regarding the influence of rooting substrate on morphological characters of two varieties of Argyranthemum frutescens L. cuttings („Gypsy Rose” and „Butterfly”), which were followed the rooting process in different substrates (perlite and peat + perlite).
