In the frame of 'Baltic fruit rootstock studies' apple rootstocks B.9, B.146, B.396, B.491, P 2, P 22, P 60, M.9, M.26, Jork 9, Bulboga and Pure 1 were tested in Estonia, Latvia and Lithuania. More vigorous tree growth was recorded following North-South direction being the weakest in Estonia and the strongest in Lithuania. Apple rootstocks can be grouped, according to the induced tree vigour, in the following way: less vigorous than M.9: P 22, the same as M.9: Pure 1, B.396, Jork 9, P 60, B.9 and P 2, between M.9 and M.26: B.491, more vigorous than M.26: Bulboga and B.146. Rootstock effect on cumulative yield and cumulative yield efficiency index was...

Phenotypic diversity of autochthonous European (Prunus domestica L.) and Damson (Prunus insititia L.) plum accessions based on multivariate analysis

T. Milošević, N. Milošević

Hort. Sci. (Prague), 2012, 39(1):8-20 | DOI: 10.17221/99/2011-HORTSCI  

Forty-three European (Prunus domestica L.) and twelve Damson (P. insititia L.) plum accessions originating from different and important growing regions in former Yugoslavia were studied to assess the overall degree of polymorphism, detect similarities among accessions and assess important agronomic, fruit quality and sensorial traits. Twenty variables were scored and subjected to multivariate analysis. Results showed a considerable phenotypic diversity among plum germplasm. A high correlation was found among some evaluated variables. Principal component analysis (PCA) revealed that traits related to fruit weight, yield and soluble...

In vitro establishment and proliferation of red currant cultivars

J. Sedlák, F. Paprštein

Hort. Sci. (Prague), 2012, 39(1):21-25 | DOI: 10.17221/40/2011-HORTSCI  

The goal of this study was to investigate in vitro multiplication protocols for use with red currant cultivars grown in the Czech Republic. Cultivars Detvan, Vitan and Rotte Höllandische were successfully established in vitro using mercuric chloride in a concentration of 0.15% as a sterilization solution. The overall rate of contamination was 25.7%. Two proliferation media Murashige and Skoog medium (MS) and McCown woody plant medium (WPM) containing 1 or 2 mg/l of 6-benzylaminopurine (BAP) were tested. Initial explants produced new plants in the form of rosettes. Rosettes arose from the base of the initial explants in the...

Effect of salt stress on physiological response of tomato fruit grown in hydroponic culture system

M.M. Hossain, H. Nonami

Hort. Sci. (Prague), 2012, 39(1):26-32 | DOI: 10.17221/63/2011-HORTSCI  

The effect of salt stress on physiological response of hydroponically grown tomato fruit was investigated. Fruit growth rate, water status, cuticle permeability and induction of blossom-end rot (BER) of tomato fruit were considered for this study. Salt stress was applied by using Ca salt treatment and it plays an important role on all parameters studied in this experiment. Fruit growth rate, predawn water potential, osmotic potential and cuticle permeability were significantly lower in treated plants than in control plants. On the other hand, tissue turgor of control and treated fruit showed almost similar values 12 days after flowering (DAF). This...

RAPD-based analysis of differences between male and female genotypes of Asparagus officinalis

Y. Ii, A. Uragami, Y. Uno, M. Kanechi, N. Inagaki

Hort. Sci. (Prague), 2012, 39(1):33-37 | DOI: 10.17221/70/2011-HORTSCI  

Asparagus (Asparagus officinalis L.) plants are dioecious. All-male cultivars are desired because of their higher yields. To increase the proportion of male individuals planted in the field and expedite the breeding of all-male cultivars in asparagus, development of generally applicable molecular markers to distinguish male and female individuals is required. Bulked genomic DNA samples from ten male (XY) and ten female (XX) plants was screened with 10-bp random primers. Of the 188 primers tested, the primer T35R54 produced a 1600-bp fragment observed only in male individuals. The specificity of this T35R54-1600 marker was verified using DNA...

Influence of terroir on the concentration of selected stilbenes in wines of the cv. Riesling in the Czech Republic

M. Kumšta, P. Pavloušek, J. Kupsa

Hort. Sci. (Prague), 2012, 39(1):38-46 | DOI: 10.17221/126/2010-HORTSCI  

The relationship between the terroir and the quality of grapes and/or wines is used in wine authenticity determination based on geographical origin. The phenolic compounds in grapes and wines are probably related to the terroir. The subject of the study was the analysis of 43 wines of the cv. Riesling from six wine-growing sub-regions, 16 different localities and four vintages to determine the content of trans-resveratrol, trans-piceid, cis-resveratrol and cis-piceid. The analyses were performed using an HPLC method. A relationship was observed between trans-resveratrol concentration in wines and wine-growing...

Organic growth supplement stimulants for in vitro multiplication of Cymbidium pendulum (Roxb.) Sw.

Saranjeet Kaur, K.K. Bhutani

Hort. Sci. (Prague), 2012, 39(1):47-52 | DOI: 10.17221/52/2011-HORTSCI  

The aim of this study was to establish protocol for in vitro regeneration and multiplication of Cymbidium pendulum through protocorms, as explants using organic growth supplements such as banana homogenate, coconut water, and peptone. The effect of growth supplements was tested on multiplication (neo-formation of secondary protocorms from primary protocorms) of protocorms, development of maximum number of shoots and early plantlets in M medium (Mitra medium). Though the explants regenerated in the absence or presence of growth adjuncts in the medium; the regeneration frequency was found significantly higher in organic growth...
