Influence Of Iron Sources In The Nutrient Medium On In Vitro Shoot Multiplication And Rooting Of Magnolia And Cherry Plum

Abstract

In this study, the effects of compounds providing Fe in chelated (NaFeEDTA and Fe(III)AC) and non-chelated (FeSO4·7H2O) forms as components of culture media, on in vitro shoot multiplication and rooting of Magnolia soulangeana ‘Alexandrina’, Magnolia grandiflora and Prunus cerasifera ‘Nigra’ were comparatively evaluated. Each of the tested chemicals was used as a single Fe source in the basal salt medium. In the stages of shoot multiplication and rooting plant response was scored by biometrical indices (number of shoots, leaves and roots, shoot and root length, percent of rooted plants and root hairs). The occurrence of physiological disorders was estimated by visual observations. In presence of FeSO4, symptoms of chlorosis, hyperhy-dricity, early senescence and specific morphology of roots, suggesting Fe deficiency, were observed. These deteriorations were entirely prevented at the application of Fe chelates of which, in this experimental systems, Fe(III)AC was tested for the first time. The addition of Fe(III)AC positively affected the plant quality to extent comparable to that of NaFeEDTA. The obtained data suggest that both applied Fe chelates are more appropriate than non-chelated Fe form and can be alternatively used in the optimization of nutrient media for micropropagation of Magnolia and Prunus cerasifera genotypes.

Fruit characteristics of six candidate olive cultivars

Abstract

Some important physical, chemical and sensory characteristics of raw and processed olives (processed by the same scratched table olive process) were investigated. In the study, six candidate cultivars obtained by cross-breeding and one standard cultivar (‘Domat’) grown together in an olive breeding and observation plot in the Ataturk Central Horticultural Research Institute in Turkey were investigated. Fruit weight and flesh-to-seed ratio of fresh raw olives ranged from 5.18 to 7.65 g and 4.8 to 6.3, respectively. LT011 had the highest fruit weight, whereas LT001 and LE001 had the highest flesh-to-seed ratio. Total phenolic content and antioxidant activity of the produced table olives were estimated between 102 and 141 mg gallic acid equivalents per 100 g−1fresh weight, and 13.4 and 14.9 µmol Trolox 100 g−1, respectively. Fruits of LT001 had higher appearance, taste, bitterness and general appreciation scores than the others. LT001 showed a lesser loss of oleuropein absorbance and antioxidant activity than the others during processing. The results of this study revealed that LE001, LT001 and LT011 had superior characteristics for the production of scratched green table olives.

Quality Potential Of Some New Pear Cultivars – How To Obtain Fruit Of The Best Sensory Characteristics?

Abstract

The eating quality of nine new pear cultivars grown in Poland was investigated in 2008-2011. Fruits of two summer cultivars: ‘Alfa’ and ‘Radana’, as well as late season varieties: ‘Hortensia’, ‘Dicolor’, ‘Concorde’, ‘Uta’, ‘Xenia’, ‘Erika’ and ‘Verdi’ were compared to fruits of ‘Clapp’s Favorite’ and ‘Conference’, which were taken as cultivars of reference. Fruits of all cultivars were harvested from the Experimental Orchard of the Research Institute of Horticulture at the commercial maturity stage and stored at +2.5 °C or -0.5 °C in a normal atmosphere (NA) or at -0.5 °C in a controlled atmosphere (CA) (0.7% CO2 : 2% O2) for 6 to 16 weeks. At the end of storage, the fruits of each cultivar were subjected to an individual ripening schedule at 18 °C (up to 14 days), which generated samples of diversified quality attributes. Based on instrumental analyses and descriptive sensory assessment the quality attributes of each cultivar were examined. The gathered data on the dynamics of quality attribute changes during the ripening stage confirm that each new cultivar needs an individual strategy during storage and ripening in order to maximise their specific sensory attributes to increase potential market value. The obtained data leads to the conclusion that ‘Xenia’ and ‘Concorde’ fruits have the biggest chance to fulfil consumer expectations, as they were appreciated more than the reference ‘Conference’ cultivar. Among the others also ‘Hortensia’, ‘Verdi’ and ‘Dicolor’ were scored higher than ‘Conference’, but their advantages were not so evident.

Role of small and intermediate towns in regional development: A case study of Raebareli, Sultanpur and Pratapgarh Districts of Uttar Pradesh, India

Abstract

It is said that small and intermediate size towns play a significant role in the socio-economic transformation of regional spaces through diffusion of innovations. It, however, has been hypothesized here that in this diffusion process the villages having better infrastructural facilities and services, play central role. For its analysis, the study takes the case of a region consisting of three administrative districts - Raebareli, Sultanpur and Pratapgarh, of the Uttar Pradesh state of India. These districts have remained in political focus since India’s independence and have elected two prime-ministers and some most influential politicians of their times in quest of development. However, the condition of development here is still deplorable. These districts have 22 statutory towns, and are least urbanized in the state. The towns are mainly administrative or market centres in nature serving surrounding villages by their backward and forward linkages. The study analyses ‘Z scores’ of select services to measure the level of development at block and village level, and portrays the spatial arrangement of towns in development setting of the region. The study observes that while towns are instrumental in promoting regional development, the role of ‘rurban’ centres (high service villages) in the process of diffusion of development is pivotal.

Evaluation of the suitability of Festuca rubra L. and F. nigrescens Lam. ecotypes as a material for lawn grass breeding

Abstract

In the years 2004-2006, 37 F. rubra L. ecotypes and 35 F. nigrescens Lam. ecotypes were evaluated for their main lawn traits: the general aspect of the plant, slow re-growth, overwintering, winter greenness, leaf fineness and disease resistance. The lawn properties of the ecotypes were assessed with the use of the IHAR 9-grade scale of the visual quality classification system. The study individuals were compared with the model varieties: F. rubra ‘Areta’ and F. nigrescens ‘Nimba’. The ecotypes originated from natural localities in the Lublin region. The experiment was conducted using the method of randomly chosen blocks in three repetitions. One repetition contained six plants of one ecotype grown at a distance of 75 × 30 cm. The aim of the study was to analyze the variability of lawn traits in the examined F. rubra and F. nigrescens ecotypes and to estimate the suitability of the selected material for the breeding of new lawn varieties. Analyses indicated that most of the ecotypes that grow in natural localities in the Lublin region display high-grade lawn traits. This confirms the great suitability of the wild plants for further breeding. Ecotypes of both species obtained high scores comparable with model varieties for their disease resistance, leaf fineness and winter greenness, and also for general aspect and slow re-growth.

Study on the quality of wines produced from ‘Syrah’ and ‘Tempranillo’ cultivars planted in two microregions in Southern Bulgaria

Study on the quality of wines produced from ‘Syrah’ and ‘Tempranillo’ cultivars planted in two microregions in Southern Bulgaria

In the period 2006-2008 a comparative study was carried out on the ‘Tempranillo’, ‘Syrah 99’ and ‘Syrah 100’ cultivars, grown in two microregions in Southern Bulgaria - Brestnik and Pesnopoy. The soils in the region of Pesnopoy are of a better mechanical and chemical composition, which preconditions the formation of relatively high yields of good quality grapes. The ‘Tempranillo’ cultivar was highly productive in both microregions, however the quality of the wines was lower, compared to the ‘Syrah’ cultivar. They were poorer both in the content of extract and in fruit aroma. ‘Syrah 99’ from Brestnik and ‘Syrah 100’ clones from Pesnopoy do not differ significantly in productivity, but the wines of ‘Syrah 100’ from the Pesnopoy region were more intense in colour and their aroma was strong, full-bodied and lasting with dominating floral (violet) and forest fruit nuances. Tasting results showed high scores, which is evidence that the young wines have potential and contain the ingredients and components necessary to develop further into top quality red wines.
