The study conducted over the period 2008-2012 demonstrates labour intensity requirements for dormant pruning of selected apricot varieties (Leskora, Betinka, Marlen) on different rootstocks (Julior, M-LE-1, Penta, Tetra, Green Gage, Ishtara and MY-KL-A). The pruning and the assessment of time needed for pruning bearing trees was done in early spring each year during the given period. The results indicate that the labour intensity, i.e. time required to prune the tree depends on variety/rootstock combination. The control variety Marlen on M-LE-1 rootstock required the least amount of time for pruning (138.3 s). Compared to the control, variety Leskora...

Hort. Sci. (Prague), 2013, 40(4):149-153 | DOI: 10.17221/114/2013-HORTSCI  

Three new plum cultivars named Kamir, Samera and Simona were evaluated together with standard cultivars (Čačanská Lepotica, Čačanská Raná and Hanita) in a trial orchard established in the spring of 2004. These cultivars differ significantly among each other in tree vigour. Cv. Simona is the least vigorous whereas cv. Kamir the most. Regarding fruit harvest time, cv. Simona is the earliest one (early August), whereas cv. Kamir is the latest one (early September). The fruit size of the new cultivars, except for cv. Simona is comparable to the standards used in this study. The most productive in the first years of evaluation was cv. Kamir but later on...

Biological and chemical properties of cv. Willamette were contrasted with those of cvs Tulameen, Latham, Meeker and K81-6 grown under agro-environmental conditions of Western Serbia. The following parameters were examined: yield per unit land area, total dry matter content, soluble solids content, total reducing sugars, total acids content, pH value, total pectines and total anthocyanins. The obtained results showed that cvs Willamette and Meeker had exceptional yield potential and highest quality fruits, which renders them suitable for both fresh use and various forms of processing, whereas cv. Tulameen can be recommended for fresh consumption only....

Behaviour of consumers of conventional and organic flowers and ornamental plants in ItalyOriginal Paper

Hort. Sci. (Prague), 2013, 40(4):162-171 | DOI: 10.17221/115/2013-HORTSCI  

The paper analyses preferences and motivations of Italian consumers of flowers and ornamental plants, both conventional and organic. The results helped to outline their profile. Purchases are still done in the traditional places (flower shops for cut flowers and plant nurseries for potted plants), however positive trend is found for potted plants purchases at large distribution chains. Some differences came out as to purchase motivations: cut flowers are mainly bought in special occasions whereas potted plants purchases are linked to personal use. The results confirm a positive relationship between the purchase of flowers and plants and the age of...

Conditioning is a simple and effective method of post-harvest longevity of both flowers and florists' greens. Performing this treatment immediately after harvest by the producer increases the quality of floral products expressed as their post-harvest longevity. The purpose of this study was to assess the influence of four growth regulators from the gibberellin and cytokinin groups applied as a 4-h conditioning treatment of leaf blades and to determine any effects on post-harvest longevity of leaves of Limonium latifolium. The leaves were harvested early in the morning from the department of ornamental plants collection. Selected leaves were...

Effect of short-term exposure to red and blue light on dill plants growthOriginal Paper

Effect of the end-of-day and the end-of-night red and blue light in dill growth was investigated. Ambrozja dill (Anethum graveolens L.) cvs were grown in vegetation chambers in completely controlled conditions exposed to white diode light. Red and blue light was employed for 30 min before the initiation or after the end of the lighting period. The values of plant fresh mass, area and height parameters were the highest for plants treated with red light at the end of night. The application of red light at the end of day exerted a similar effect on plants as the exposure of plants to blue light at the end of night. Plants treated with...

The effect of the chemotherapy with ribavirin on the elimination of the pome fruit viruses from in vitro grown plants of infected apple cv. Fragnance has been investigated. The results of ELISA and RT-PCR testing proved the presence of mixed infection of Apple stem pitting virus (ASPV), Apple chlorotic leaf spot virus (ACLSV) and Apple stem grooving virus (ASGV) in the initial field-grown tree of this apple cultivar. Obtained actively growing in vitro shoots with well-developed leaves and shoot tips were subsequently used for chemotherapy with ribavirin. Attempts to fully eliminate viruses by ribavirin in...
