Tree vigour, occurrence of mildew and scab, yields, yield efficiency, fruit weight, flesh firmness and soluble solids content of apple trees on M 9 rootstock were monitored between 1998–2005 in 42 commercial orchards situated in all the major growing regions of the Czech Republic. Altogether 50 cultivars were included into the evaluation. The characteristics of newly bred or newly introduced cultivars were compared to the cultivars of standard assortment such as Gloster, Golden Delicious, Idared, Jonagold, Melrose, Rubín and Šampion. The group of late ripening cultivars imported from France (Baujade, Early Smith, Granny Smith and Red Winter) proved to be unsuitable for climatic conditions of the Czech Republic. Cultivars of the Rubín group (Bohemia, Gold Bohemia) showed a better quality of fruits than the cultivars of the Jonagold group, but were significantly inferior regarding yields and yield efficiency. The cultivars Rucla, Pinova and Rubinstep seemed to be potential competitors of Jonagold or Rubín; their fruit quality is similar to Rubín, and their yield efficiency is comparable to that of Jonagold. Topaz, which is resistant to scab and has recently spread in the Czech Republic, is specific for its early yield and a very good productivity observed in a majority of the orchards. In addition, characteristics of other evaluated cultivars and their potential prospects for growing in the Czech Republic are briefly discussed.

The paper examines the influence of three clonal rootstocks ('Pixy', 'Fereley' and 'St. Julien A') along with seedlings of Myrobalan (control) on the growth, yield and fruit quality of the plum cultivar 'Cacanska Rana'. Research was conducted in the area of the Belgrade Danube basin for the six-year period (2013-2018). In comparison to control, all three clonal rootstocks have shown a significant effect on the decrease of vigor expressed as a trunk cross-sectional area. The lowest vigor was found in trees on the 'Pixy' rootstock, then on 'Fereley' and 'St. Julien A' rootstocks. Regarding the rootstocks 'Fereley' and 'St. Julien A', significantly higher fruit set and yields were achieved in comparison to control. Clonal rootstocks induced an increase in the yield per hectare ranging from 72% to 93% compared to Myrobalan. The highest yield efficiency was found in the trees on the 'Fereley' rootstock, followed by the yields observed in the trees on the 'Pixy' and 'St. Julien A' rootstocks. Significantly higher fruit weight compared to control was obtained in the trees on the 'Fereley' rootstock. Rootstocks did not show any significant effect on the soluble solids and total acid contents of the fruit. Based on the results obtained, it can be concluded that all three clonal rootstocks showed better results than Myrobalan, and can be recommended for establishing intensive plum plantations with higher planting density. The best results in terms of yield and fruit quality were obtained with the 'Fereley' rootstock.

AbstractThe present study evaluated the quality of kiwiberries produced in the territory of the Czech Republic in 2018 and 2019. Actinidia arguta is a very hardy and flexible species which can produce fully ripe fruits even in the setting of moderate climatic zones unlike commercially available A. chinensis as a variety which needs a longer season with higher temperatures to become fully ripe. Once harvested, the fruit was studied for soluble solids content, titratable acidity, antioxidant activity and the content of malic, citric and ascorbic acids. Unlike commercially available kiwifruits, kiwiberries lack hair and can be consumed unpeeled. The results of the present study confirmed the notable potential of kiwiberries consisting namely in the levels of antioxidants present in the skin of the fruit. Kiwiberry fruits feature a higher level of acidity than is common in conventional commercial varieties of A. chinensis as citric acid is the type of acid prevailing in the fruit at all times.

This study was aimed at evaluating of 14 new apricot cultivars created at the Faculty of Horticulture in Lednice in the Czech Republic in order to recommend the best of them for growing in the Belgrade region. The study was carried out at the Experimental station ?Radmilovac? of the Faculty of Agriculture in Belgrade over a period of five years (2009-2013). The experimental orchard was established in 2007, the rootstock was Myrobalan seedling, and tree spacing was 4.5 x 3 m. The control cultivar for comparison was the clone of ?Velkopavlovick?? cultivar (type of ?Hungarian Best?), LE-12/2. Flowering of introduced cultivars started from three days before to one day after the control cultivar, while the maturation time ranged from 19 days earlier in cultivar ?Leskora? to 12 days after the control in cultivar ?Sophia? (LE-2926). Compared with the control cultivar, significantly higher yield was achieved only in cultivar ?Palava?, while significantly higher fruit weight was recorded in three cultivars: ?Candela? (LE-2927), ?Sophia? (LE-2926) and ?Betinka? (LE-3276). Cultivars ?Sophia? and ?Betinka? got the best scores for fruit appearance, while cultivars ?Marlen? and ?Lebona? ranked the highest for fruit taste. Among studied apricot cultivars, for the cultivation in the Belgrade region, the following cultivars can be recommended as promising: ?Palava? (early season), ?Betinka? (mid-season) and ?Sophia? (late season). Regarding the large size and attractive appearance of fruits, these cultivars are more suitable for fresh consumption, but they can also be used for processing.

The cherry rootstock influences the performance of the scion cultivar. It has an effect on cherry fruit quality, tree growth, yield and yield efficiency and floral and foliar nutrition. In this work, the influence of Saint Lucie 64 and Maxma 60 rootstocks on the fruit quality traits of cv. Early Bigi was evaluated. For this, several parameters, namely fruit weight (FW) and size (FS), soluble solids content (SSC), pH, titratable acidity (TA), flesh firmness (FF), epidermis rupture force (ERF), color and sensory profile, were assessed. Results showed that the fruits from trees on Saint Lucie 64 presented higher FF and ERF values and, consequently, better texture. On the other hand, fruits from trees on Maxma 60 showed sweeter cherries (higher SSC). Moreover, these trees presented the darkest cherries (lower values of L*, a*, b*, C* and hue°) and the highest SSC. Therefore, although the trees on Saint Lucie 64 produced firmer cherries, it was those with the Maxma 60 rootstock that produced sweeter and darker fruits. In conclusion, both scion–rootstock combinations proved to be good options for the region of Resende.

Tree growth, yield, and fruit quality of eight lemon cultivars [Citrus limon (L.) Burro. f.] on macrophylla (Alemow) (C. macrophylla Wester) rootstock were compared when grown in sandy soil in the arid climate of south-western Arizona. `Foothill Lisbon' had higher cumulative yield and titratable acids than `Monroe Lisbon', `Prior Lisbon', `Eureka', and `Villafranca', and had larger fruit than other `Lisbon' cultivars. `Prior Lisbon' produced a larger tree canopy with lower yield efficiency than all other cultivars and did not show any decline due to sieve tube necrosis 12 years after planting. Overall, `Eureka' cultivars and `Villafranca' had lower relative cumulative yields, canopy volumes, total soluble solids content, titratable acids, and seed content, but higher tree decline than `Lisbon' cultivars. Overall, `Foothill Lisbon', in spite of carrying exocortis viroid, produced good yields and fruit quality and `Prior Lisbon' had a satisfactory growth-performance.

Phenological characteristics, yield and fruit quality of 14 medium-late ripening plum cultivars, were studied in the region of Belgrade during the five-year period (2013-2017). The control cultivar for comparison was ?Cacanska rodna?. Flowering of tested cultivars occurred in the first half of April, and fruit maturation was in the first half of August. The average yield per tree was the lowest in the ?Nevena? cultivar (1.6 kg), and the highest in the ?Mildora? cultivar (22.5 kg). Compared to the control cultivar, significantly lower yield was achieved in seven cultivars. The lowest vigor was determined in the standard cultivar (?Cacanska rodna?), and the highest in the ?Milka? cultivar. The average fruit weight ranged from 19.5 g in the ?Nevena? cultivar to 50.5 g in the ?Valor? cultivar. Compared to the control, fruit weight was statistically significantly higher in five cultivars. In all studied cultivars, the high soluble solids content (over 17%) was found, while in cultivars ?Mildora? and ?Valor? it was significantly higher than in the control. On the basis of the obtained results, as regards cultivation in the region of Belgrade, it is possible to recommend the following cultivars: ?Valor? and ?Cacanska najbolja? as predominantly table cultivars (for fresh consumption), ?Jojo? and ?Vengerka krupna slatka? as cultivars of combined characteristics and ?Mildora? as a cultivar for processing.

Orchard performance is influenced by weed competition. In this study, the effects of weed competition on nutrient contents, chemical and physical fruit quality properties were sought. The study was carried out in a high-density apple orchard (‘Golden Delicious’/M.9) over two consecutive growing seasons. The effect of weed competition was studied at three different levels: weak, moderate and strong. Fruit firmness, soluble solids content, macronutrients (such as nitrogen, potassium and calcium) and potassium+magnesium/calcium ratio in fruit were significantly affected by weed competition. Strong weed competition negatively affected soluble solids content and potassium+magnesium/calcium ratio. In both trial years, soluble solids content was significantly higher in weak weed competition. In the first year of the study, soluble solids content ranged between 13.77±0.06% (strong weed competition) and 15.20±0.10% (weak weed competition). In the following year, soluble solids content values were determined as 13.13±0.23% in strong weed competition and 13.83±0.21% in weak weed competition. Weak weed competition showed superiority for fruit weight and potassium+magnesium/calcium ratio. As a whole, this study indicates that insufficient weed control in tree rows might be a limiting factor for fruit quality in high-density apple orchards.

Yield And Quality

The strawberry cultivation is an important economic activity in the Rio Grande do Sul State, Brazil, however the number of offered cultivars to the growers is reduced. The yield and quality of strawberry (Fragaria x ananassa Duch.) cultivars Camarosa, Galexia, Earlibrite, Festival, Plarionfre and Sabrosa was evaluated under the climatic conditions of Pelotas, Rio Grande do Sul State. We determined the number, mass, total soluble solids (TSS ºBrix), total titratable acidity (TTA), antocianin level and fresh fruits produced in an experimental unit. We also determined the production of fruits per hectare and per plant. The statistical design used in the experiment was of completely randomized blocks with 6 treatments (cultivars) and 4 replicates where the experimental unit was composed of 8 plants. The harvest began in the first half of August, extending to the second half of December, totalling 20 weeks. Plarionfre, Earlibrite and Festival cultivars showed higher production from the first half of October until the end of the first half of November. Camarosa reached higher productivity, mass of plants and fruit weight. There were no differences between the evaluated cultivars in the levels of TSS, antocianin, ATT and pH during the period of evaluation.

Prevalence of heavy soil is a major problem for fruit cultivation under Punjab conditions consequently leading to deficiency of several micro-nutrients including zinc (Zn), iron (Fe), and manganese (Mn) which adversely affects the growth and productivity. In this view, a study was planned to investigate the effect of foliar applications of zinc sulphate (ZnSO4), iron sulphate (FeSO4), and manganese sulphate (MnSO4) on vegetative growth, reproductive growth and fruit quality of papaya cv. Red lady. Plants sprayed with ZnSO4 (0.4 %) exhibited significantly highest plant height, plant girth, number of leaves, petiole length; initiated an earliest flowering and fruiting; and improved fruit quality viz., fruit weight, fruit length, titratable acidity, soluble solids concentrations, ascorbic acid content, total phenols content, and total carotenoids content as compared with the control and all other treatments. In conclusion, foliar application ZnSO4 (0.4 %) significantly improved plant growth and fruit quality in papaya cv. Red lady.

The Relationship

Girdled or nongirdled `Biscoe' peach (Prunus persica [L.] Batsch) secondary scaffold branches were covered with shade fabric to provide a range of photosynthetic photon flux densities (PPFD) from 44 to 20 days before harvest (DBH), from 20 to 0 DBH or 44 to 0 DBH. Fruit quality was affected differently by the various periods of shade during the final swell of fruit development. Shading 40 to 20 DBH did not affect fruit weight or quality, whereas shading 44 to 0 DBH had the greatest effect on fruit weight and quality. Fruit quality was generally similar on branches exposed to 100% and 45% incident PPFD (IPPFD). Fruit on” girdled branches generally responded to shade more than fruit on nongirdled branches. Fruit weight was positively related to percent IPPFD for girdfed but not nongirdled branches shaded 20 to 0 DBH and 44 to DBH. On nongirdled branches, fruit exposed to 45% IPPFD for 44 to 0 DBH had 14% less red color and 21% lower soluble solids content (SSC) than nonshaded fruit. Harvest was delayed >10 days and preharvest fruit drop was increased by shading to <23% IPPFD. Shading branches for 20 to 0 or 44 to 0 DBH altered the relationship between flesh firmness and ground color: Firmness declined as ground color changed from green to yellow for fruit shaded 44 to 20 DBH, but firmness declined with little change in ground color for fruit shaded 20 to 0 or 44 to 0 DBH. Girdling results indicated that fruit weight and SSC partially depended on photosynthate from nonshaded portions of the canopy, whereas fruit redness, days from bloom to harvest, and ground color depended on PPFD in the vicinity of the fruit.
