Late Maturation

Phenological traits, yield, and fruit characteristics of 14 plum cultivars of late maturation period were stud-ied in the region of Belgrade in the five-year period (2013–2017). The control cultivar for comparison was ‘Stanley’. The average time of flowering was in the first half of April, and of fruit maturation in the second half of August and the beginning of September. Yield per tree was lowest in the cultivar ‘Pozna Plava’ (10.2 kg) and highest in the cultivar ‘Topking’ (23.6 kg). Compared to the control, significantly lower yield was achieved in three cultivars: ‘Pozna Plava’, ‘Vengerka Pozdnyaya’, and ‘Narach’. Fruit weight ranged from 26.1 g in the cultivar ‘Elena’ to 57.0 g in the cultivar ‘Empress’. Compared to the control, it was sig-nificantly higher in three cultivars (‘Empress’, ‘Vengerka Pozdnyaya’, and ‘Tophit’). All studied cultivars had high soluble solids content, ranging from 17.1% to 21.6%. The best rated cultivar for fruit appearance was ‘Empress’, while cultivars ‘Nada’ and ‘Pozna Plava’ were best scored for taste.

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.

Twelve commercial and promising mango cultivars were evaluated at three agroecological zones of Bangladesh viz., Akbarpur (AEZ 29), Chapai Nawabgonj (AEZ 11), and Gazipur (AEZ 28) during 2006-07 to investigate their regional adaptability. Cultivars included in the experiment were Ashwina, BARI Aam-1, Bombai, Deori, Fazli, Gopalbhog, Kalia, Khirsapat, Langra, Lata Bombai, Rani Passand, and Surjapuri. The plants were transplanted in the field during July 1993. Tree volume was the maximum (79.78 m3) in Khirsapat and the minimum in Lata Bombai (21.92 m3). Langra had the highest percentage of perfect flower (27%), while the lowest was in Deori and Kalia (5%). The earliest and latest fruit was harvested from BARI Aam-1 and Ashwina, respectively, at all locations. All the cultivars were harvested 3-5 and 8-10 days earlier at Akbarpur and Gazipur, respectively, compared to that at Chapai Nawabgonj. The highest individual fruit weight was obtained from Fazli at all locations, while Gopalbhog (130 g) had the lowest fruit weight at Akbarpur and Surjapuri at Chapai Nawabgonj (172 g) and Gazipur (140 g). Total soluble solids content was reasonably high in all the cultivars at each location (around 20%) except Ashwina, Lata Bombai, and Surjapuri which contained around 16% TSS. Lata Bombai was highly susceptible to anthracnose, floral malformation, and stem-end-rot at almost all the locations. Other cultivars showed low to medium susceptibility to all these diseases. The highest and lowest fruit producing cultivars were Khirsapat (206) and Lata Bombai (106) at Gazipur, while Rani Passand (196) and Bombai, Lata Bombai (92) at Akbarpur but at Chapai Nawabgonj, these were Langra (325) and Deori (117), respectively. Cultivar Fazli (83.61 kg) was the highest yielder by weight, while Lata Bombai (18.35 kg) was the lowest. Among the locations, Chapai Nawabgonj was the most favourable for plant growth, perfect flower production, and yield, and least favourable for pests and diseases. The overall result of the experiment indicated that good quality mango could also be grown successfully under Akbarpur and Gazipur conditions adopting appropriate variety like Khirsapat.

Yield and quality reductions in watermelon infected with Didymella bryoniae may be attributed to reduced number or weight of fruit, sunburned fruit, fruit rot, or low sugar content due to gummy stem blight on foliage and black rot on fruit. Number, weight, soluble solids content, and external appearance of fruit were determined in four experiments conducted in fall 1996 and 1997 and spring 1997 and 1998. Severity of gummy stem blight was varied by applying no fungicide, mancozeb, or chlorothalonil according to different schedules. In the fall, when disease severity was high, total fruit weight, percent marketable fruit, and soluble solids content were lower and percent fruit with black rot was higher in nonsprayed than in sprayed treatments. Fungicide applications did not affect total fruit weight, soluble solids content, or black rot in the spring, when disease severity was moderate to low. Percent sunburned fruit was greater in treatments sprayed every 14 days than in those sprayed weekly. In fall experiments, the number of healthy, unblemished fruit increased linearly as the number of fungicide applications was increased from zero to nine per season. Yield losses in watermelon to gummy stem blight and black rot resulted primarily from a reduction in total fruit weight and an increase in number of diseased and sunburned fruit.

Twenty melon (Cucumis melo L.) cultigens (cultivars and breeding lines) were tested for salt tolerance. All cultigens were grown in the field using drip irrigation at three salt salinity levels: electrical conductivity (ECw = 1.2, 7.5, or 14.0 dS·m-1. Nineteen of the 20 cultigens proved to be salt-sensitive, as measured by reduction in fruit weight, but not necessarily to the same degree (i.e., some cultigens were tolerant at ECw = 7.5, whereas others were not). One line, `Evan Key', was salt-tolerant at ECw= 14.0. Increasing salinity levels did not affect the number of fruits produced in most cultigens. Overall, increasing salinity reduced netting quality but increased the total soluble solids content and shortened mean time to harvest in seven cultigens.

Sweet Cherry Cultivars

Banjaluka region is characterized by a very rich diversity of old and autochthonous sweet cherry cultivars, which represent a very important genetic potential for future breeding programs. Autochthonous sweet cherry cultivars are spontaneously propagated and used in very few areas for production and consumption in the fresh condition. A very small percentage of autochthonous cultivars are used in local markets or in some forms of processing. The main reason for this is the small number of individual trees whose fruits are used for own household and their poor management. In order to popularize the production and sale of autochthonous sweet cherry cultivars, during this research was perform the basic pomological measurements of the five most common autochthonous sweet cherry cultivars in the Banjaluka region (Ašlamka, Banjalučka crnica, Bjelica-Biljur, Cipov and Crveni hrušt). Pomological (the weight and dimensions of the fruit, weight and dimensions of the pit, dimension of the stalk and the firmness of the fruit flesh) and chemical (total soluble solids content of the fruit) fruit characteristics were determined. Results showed differences in investigated parameters between the cultivars.

The effect of climate was observed on fruit quality of four low-chill peach cultivars (Flordaprince, Flordaglo, UFGold, and TropicBeauty). The cultivars were evaluated in three locations (north–central, central, and southwest Florida). Soluble solids content (SSC), titratable acidity (TA), SSC:TA ratio, fruit weight, blush, and fruit development period (FDP) were determined. Longer FDPs were observed at the north–central location than at the southwest location. Fruit development and the expression of quality attributes were affected by location during fruit growth with higher color and SSC and shorter FDP occurring under warmer conditions. Within locations, ‘UFGold’ had the shortest FDP except at the southwest location where its chilling requirement may not have been met. At the central and southwest locations, ‘UFGold’ also tended to have lower TA values and higher SSC;TA ratios than the other cultivars.

Fruit Load

The effects of fruit load, leaf area, night temperature, cultivar and ripening stage on the soluble solids content (SSC) of muskmelons were studied in a series of experiments performed during spring, summer and autumn in heated glasshouses. All factors except fruit load were found to affect SSC. In every experiment the duration of the maturation period (i.e. from fruit set to harvest) was positively correlated with SSC. In order to obtain fruits with a high SSC, it is important to achieve a low rate of fruit growth, i.e. a long maturation period. Low night temperatures in the period of fruit growth, a high leaf area, harvesting only ripe fruits and selecting slow-ripening cultivars may contribute to the production of fruits with high SSC.
