Apple production provides, directly or indirectly, employment and improvement in the living standards to millions of people, playing a key role in rural economies. We have conducted an interview-based survey to assess the current status and challenges faced by apple production in the Batna and Khenchela provinces, the two most important apple producing regions of Eastern Algeria. The survey was conducted between March and November 2019. A total of 50 apple growers answered 40 questions, including 13 direct and 20 qualitative questions. A scale ranging from 1 (very low) to 5 (very high) was used as a quantitative measurement for 12 questions. The reliability index of the questionnaire was 0.827. The results identified the main challenges faced by apple growers in Eastern Algeria as: limited access to certified and clean planting material, limited knowledge of disease and pest identification, inadequate access to appropriate disease management, lack of storage facilities and transportation of harvested fruit, and insufficient knowledge of marketing and access to markets. The study also identified a need for the development of cost-effective plant multiplication, horticultural and disease management practices and educational programmes suitable for local conditions to enhance the productivity and economic benefits of apple orchards.

H.R. Wehrh. 'Sparkling Burgundy' as affected by chitosan Abstract: Breeding efforts within the Eucomis genus has resulted in the global availability of attractive cultivars with decorative leaves and inflorescences. A cultivar that is particularly valuable and attractive, but rarely cultivated due to its low propagation rate is 'Sparkling Burgundy'. In our research, we considered it advisable to check the possibility of intensifying the reproduction of the investigated cultivar by means of leaf cuttings. This study, conducted in the years 2016-2018, involved leaf cuttings collected from plants growing in an unheated polytunnel. The cuttings were soaked, watered or sprayed with 0.4% chitosan with a molecular weight of 7 000 or 10 000 g/mol. The control plants were not treated with chitosan. During the rooting period that followed, the cuttings were assessed for their chlorophyll a fluorescence and the intensity of their greenness, and for their root growth and bulb yield after five months. Chitosan applied during rooting improved some chlorophyll fluorescence parameters and the greenness index of the cuttings. Moreover, the compound with a molecular weight of 7 000 g/mol more efficiently increased the number and length of the roots and the number and weight of the adventitious bulbs than that with a molecular weight of 10 000 g/mol. Soaking the cuttings prior to rooting was more effective in terms of the number, length and weight of the produced roots and the number, diameter and weight of the daughter bulbs than watering or spraying.

China Title: Effects of water stress on the sugar accumulation and organic acid changes in Cabernet Sauvignon grape berries Abstract: The eastern foot of Helan Mountains in Ningxia belongs to the semiarid area and has been identified as the best wine grape producing area in China. In order to solve the problems of a high sugar content, organic acid falling too fast and severe shortage of acidity in the berries during ripening, which lead to lack of wine harmony, this study took Vitis. vinifera L. cv. 'Cabernet Sauvignon' as the experimental material and expanded nine treatments from setting to harvest. Nine rows were selected and divided into three groups, treated with mild (-0.20 MPa ≥ Ψb ≥ -0.40 MPa), moderate (-0.40 MPa ≥ Ψb ≥ -0.60 MPa), severe (Ψb ≥ -0.60 MPa) water stress from setting to veraison separately. From veraison to harvest, within each group, the mild, moderate, severe water stress were set, forming light-light (CK), light-medium (T1), light-heavy (T2), medium-light (T3), medium-medium (T4), medium-heavy (T5), heavy-light (T6), heavy-medium (T7), heavy-heavy (T8) treatments. The results showed that when the medium treatment was used from setting to veraison and the medium or severe treatment was used during post-veraison to harvest, it would facilitate the transportation and accumulation of sugar and improve the fruit quality.

The samples of six varieties of Vitis vinifera L. ('Hibernal', 'Malverina', 'Kolor', 'Fioletovij Augustovskij', 'Grüner Veltliner' and 'Blaufränkisch') were either lyophilised or slow dried at room temperature (three months), extracted and analysed by HPLC using DAD and FLD detectors and by LC-MS. The presence of trans-δ-viniferin was confirmed by comparison with trans-δ-viniferin prepared by dimerization of trans-resveratrol using laccase and its structure was verified by LC-NMR. The slow drying of the samples at room temperature enables the synthesis of a significant amount of stilbenes in all the studied varieties of V. vinifera canes resulting in a higher stilbene content compared to the lyophilised samples. The results of this study show the importance of the method of drying the cane sample before the extraction and analysis.
