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)

The Improvement of Floral Assortment with Ardisia Genus and the Development of Multiplication Technology by Cuttings

Ardisia genus includes 250 small trees, shrubs and subshrubs distributed in tropical and subtropical regions of the world. It used and sold in the horticulture industry as an ornamental plant – often called Christmas berry or Coral Berry, Marlberry. It is native to China, Japan and northern India, take part of the family Myrsinaceae. 65 species are in China including 14 native species in Hong Kong. Ardisia beginning cultivation in 1982, spreading into wooded areas. Currently Ardisia is found in many counties used in the landscape or indoor design for its persistent red berries, glossy foliage and low maintenance. The study involves Ardisia species A. crenata Sims. and A. pusilla A. DC. , are two species cultivated in South Korea and were brought in our country during an exchange of biological material between RDA Suwon - Korea and University of Agricultural Sciences and Veterinary Medicine Cluj in a frame of bilateral agreement. The multiplication of these species were made by cuttings and during the experience was studied the influence of rooting substrate on root system formation. Some soil mixtures were tested: I. perlite + peat + garden soil, with a ratio of 3:1:1, II. peat + sand + mature manure 2:1:1, III. peat + perlite 1:1, IV. perlite (control of experience). The best results for Ardisia crenata were obtained in mixture of peat + perlite + garden soil in 3:1:1 ratio, rooting occurred in 37 days. The process of rooting of Ardisia pusilla was finished in 58 days, and the best result was obtained in the mixture consist in of peat + sand + mature manure 2:1:1 ratio

Study on the Vegetative Propagation Through Cuttings of Mentha x piperita Hybrid using Various Rooting Substrates

The growing demand for seasoning plants and aromatic herbs on the Romanian market led to the implementation of new research on the improvement of propagation technology. Mentha x piperita was chosen for the classical propagation, a plant used not only in the food industry and in the alternative medicine, but also as an ornamental plant in the rustic gardens. It is also used with great success for decorating terraces and balconies. It is part of the compositions made for kitchens, along with other seasoning plants. The aim of the research was to improve the multiplication of Mentha x piperita hybrid. During the experiences were studied the following: the influence of the substrate on the rooting of cuttings and the influence of substrate on growth and development of plants. Recorded data were interpreted statistically by variance analysis. Results showed that the rooting process were different and depends on the substrate. Mentha x piperita has rooted in perlite in 15 days, inpeat with perlite in 20 days and in peat mixed with sand in 25 days. The number of shoots was not influenced by the substrates under study. The root system best developed in the substrate composed of peat and perlite

STUDIES CONCERNING THE INFLUENCE OF “NON WOVEN” COVER ON EARLY CABBAGE PRODUCTION CULTIVATED IN PLASTIC TUNNELS

The Agryl P-19 is a non woven floating row cover especially developed for crop protection against insects and bad weather such as rain and wind. The experiment took place in early spring 2007 of the Vegetables Growing area in a polyethylene film tunnel, where we tested three varieties of early white cabbage, cultivated under different densities with or without protection (covered with Agryl or without Agryl). As biological material we were used 3 early cabbage hybrids from Dutch: Musketeer, Surprise, and Santorino, two densities: 62.500 plants /ha, respective 71.500 plants/ha, for supplementary protecting we were used Agryl P-19. Through the combination of the 3 factors we obtained 12 experimentally variants

Evaluation of Promising Hybrids of Gladiolus hybridus L.

The genus Gladiolus contains more 255 species which grow in western and central Europe, western Asia, and in tropical and southern Africa. The main distribution area is South Africa. Most gladiolus cultivated worldwide as well as Romania has imported from the Netherlands, and only a few are created in our country. The present investigations were carried out in the experiment field of USAMV Cluj-Napoca, Floriculture Department, during of 2007-2011. In order to obtaining new cultivars were performed intraspecific crosses, involving 20 hybrid combinations between valuable genitors, followed by clonal selection of F1 hybrids. The present paper contains experimental results obtained by testing to two gladiolus hybrids F1 generations (H 8/11 and H 19/3). The morphological characteristics were evaluated and were sent for testing at ISTIS Bucharest for homologate as new cultivars

The Behavior of Some Petunias Varieties for Improvement the Romanian Assortment

Petunias are one of the most popular plants grown in pots or outdoors for summer design. The main goal of the present study was to introduce new Petunia varieties imported from Hungary that could improve the Romanian floral assortment. Lately many private flower growers from our country are looking to improve the range of new varieties of petunias in order to obtain additional income, thus justifying objectives taken to study. The trial was conducted at the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca during 2012-2013. The objectives were to evaluate the main biological and morfo-decorative characteristics of seven new petunias varieties (flower color, length flower stems, number of flowers per branch, plant circumference and diameter, and the diameter of the corolla). The data were processed by statistical analysis of variance (LSD test) and the best Petunia varieties will be promoted in our country. The results reveals the decorative potential of new Petunia varieties 'Hot red',  'White' and 'Purple' for improving the Romanian floral assortment for landscape design

RESEARCHES CONCERNING THE MAIN CHARACTERISTICS OF DAHLIA CULTIVARS TYPE DECORATIVE UNDER

Some two hundred years ago the first Dahlia arrived in Western Europe from its native habitat in Mexico. Nowadays, it is difficult to find this original Dahlia among the current Dahlia assortment as flower enthusiasts and growers have done much in the way of developing new types, shapes and colours. Together with gladioli, lilies and begonias, the dahlias are one of the most important and popular summer-flowering bulbs. Dahlias are widely cultivated due to the huge range of colours and flower types available, its many uses, and fairly easy cultivation. In recent years many new cultivars have been created and thousands of Dahlia cultivars have been introduced into the world of gardening. Although a plant of the tropics, most cultivars have been developed in temperate climates and are easy to grow in most countries. At University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, Romania researching activity for diversification of floral plants assortment by introducing of the most competitive foreign floral cultivars is one of the objectives. This paper describes 9 new Dahlia hybridus cultivars – Decorative type, with commercial origin: Sultane, Arabian Night, Vancouver, Smokey, Gloire Van Heemstede, Lilac Time, White Perfection, Bahama Yellow, Gloire Van Noordwijk. These where observed in our Transylvanian behaviors and recorded for the following morphological characteristics: blooming time, colour of flowers, plant height, and circumference of plant, number of stems, number of flower, flower diameters and number of ligules. The data were statistically computed by means of analysis of variance-LSD test to illustrate the significance of differences among studied cultivars. The cultivars studied have a rich range of flower colours (white, dark red, pink purple with striped, light yellow, orange, move, with lines or striped of different colours. Cultivars growing between 65 cm (Durban) to 109 cm (Pretoria) with different number of florets per inflorescence and have good health. The most representative Dahlia cultivars can be used for landscape design. Dahlias are absolutely perfect for borders often combined with annual plants; most of them also excel due to their extremely long flowering period. Dahlia also can be used as cut flowers
