Abstract Twenty plum cultivars on Myrobalan (Prunus cerasifera Ehrh.) seedling rootstock were tested in 2012–2017 at the Institute of Horticulture of the Lithuanian Research Centre for Agriculture and Forestry. Plum trees were spaced at 4.5 × 2.5 m and trained as spindles. Orchard floor management included frequent mowing of grass in the alleyways with herbicide strips along tree rows. ‘Duke of Edinburgh’, ‘Kijevas Vēlā’, ‘Dąbrowicka Prune’, ‘Čačanska Najbolje’, ‘and ‘Štaro Vengrinė’ cultivars were the most vigorous plum trees at the end of 6th year. Their trunk diameter achieved 92–96 mm. ‘Valor’, ‘Queen Victoria’, ‘Herman’, ‘Čačanska Najbolje’, ‘Favorita del Sultano’, ‘Ave’, and ‘Jubileum’ cultivars had the lowest trunk diameter — 72–78 mm. The highest cumulative yield of four fruiting years was recorded for ‘Kometa’ and ‘Violeta’ cultivars, respectively, 43.0 and 46.5 kg/tree. ‘Favorita del Sultano’, ‘Rausvė’, and ‘Kijevas Vēlā’ produced the largest fruits — 52–60 g. The smallest fruit occurred on ‘Dąbrowicka Prune’ and ‘Herman’ cultivars, respectively, 22 and 25 g. ‘Dąbrowicka Prune’ had the highest soluble solids content (SSC) — 19.5%. The least SSC was recorded in ‘Kometa’, ‘Violeta’ and ‘Herman’ fruits — 10.6–11.8%. ‘Renklod Rannij Doneckij’, ‘Čačanska Najbolje’, and ‘Valor’ cultivars had the highest fruit flesh firmness.

Fruit from 8 `Hayward' kiwifruit vineyards in central California were harvested at 2 week intervals after soluble solids content (SSC) reached 6% and subjected to 4 and 6 months of storage at 0°C in an ethylene free environment. Fruit characteristics at harvest and postharvest performance varied considerably among locations. Fruit stored for 6 months had the same fresh weight, less flesh firmness and higher SSC, than the 4 months storage. Later harvested fruit had greater fruit flesh firmness and higher SSC after storage. SSC after storage was predictable based on ripe soluble solids content (RSSC) at harvest. Summer pruning reduced while soil nitrogen application increased fruit SSC.

Foliar daminozide (DZ) applications to `McIntosh' apple trees (Malus domestics Borkh.) increased fruit color, reduced preharvest drop, resulted in greater firmness at harvest and after air storage, delayed starch hydrolysis, and reduced fruit ethylene production at harvest and after storage. Foliar paclobutrazol (PBZ) reduced preharvest drop and flesh firmness loss if applied within 5 weeks after full bloom (WAFB). Later applications had no effect. PBZ did not influence the progress of starch hydrolysis or ethylene production at harvest but reduced poststorage ethylene production in one season. Stem-cavity browning and brown core were increased by PBZ applied at 5 and 9 WAFB in 1987. In 1988, fruit soluble solids content (SSC) was reduced by a double application of PBZ and by uniconazole (UCZ). UCZ had little effect on `McIntosh' fruit other than the reduction in SSC. PBZ applications were less consistent in their effects than DZ. Chemical names used: butanedioic acid mono(2,2-dimethylhydrazide) (daminozide); ß-[(4-chlorophenyl) methyl]-α- -(l,l-dimethylethyl)-1H-1,2,4-triazole-1-ethanol (paclobutrazol); ß-[(4-chlorophenyl)methylene]-α-(1,1-dimethylethyl)-1H-1,2,4-triazole-1-ethanol (uniconazole).

Strawberry Breeding

Strawberry is an important fruit species whose production is increasing in the world and in our country due to its unique taste and aroma. It is known that the yield, taste and other important quality components of strawberry fruits are affected by the genetic structure as in many fruit species. In this context, a large amount of strawberry varieties have been developed as a result of strawberry breeding studies in the world. Similarly, breeding studies have been carried out at different intensities for many years at Çukurova University. In this study, the genotypes coded ‘33’, ‘36’ and ‘61’, which have become prominent as a result of the strawberry breeding program in our department, and commercial varieties such as ‘Fortuna’, ‘Rubygem’ and ‘Festival’, which are widely cultivated in the Mediterranean region, were compared in term of the properties such as soluble solids content (SSC), pH, fruit acid content and firmness during the extensive harvest period (January-May). As a result of the study, small amount of production was obtained in Mediterranean climatic conditions, and the highest SSC and flesh firmness values were obtained in the varieties and genotypes analysed in January. In terms of genotypes; the ‘36’ coded attracted attention with its relatively low acid content, as well as being higher than others with its SSC values varying between 8.0% and 13.1% throughout the season. Despite the strength of this genotype in terms of taste, it was found to be quite soft compared to commercial varieties (1.10-1.20 lb/inch2) with flesh firmness of 0.63 lb/inch2. It is thought that it is not possible to obtain the best quality variety in all aspects due to physiological and genetic reasons. However, strawberry breeders should aim to develop strawberry varieties that consist the characteristics at the highest levels in line with the fundamental goals they set.

The performance of the apple (<I>Malus domestica</I> Borkh) cultivar Imperial Double Red Delicious (Imperial D.R.D.) grafted on the following 5 rootstocks: (<I>I</I>) seedling, (<I>ii</I>) M 7, (<I>ii</I>) MM 104, (<I>iv</i) MM 106, and (<I>v</I>) MM 109 was investigated. The highest yield per tree was recorded for trees on seedling rootstock, while the lowest for the cultivar grafted on M 7. Production efficiency of Imperial D.R.D. was higher when grafted on MM 106 and M 7, intermediate on seedling and MM 104, and the lowest on MM 109. The highest leaf photosynthetic rate (Pn) was measured for scions grafted on seedling although it was not significantly different from MM 109. Nitrogen concentrations of leaves of the cv. Imperial D.R.D. grafted on M 7 and MM 106 were significantly lower in comparison to the seedling variant. Flesh firmness at harvest, pH of juice at harvest, soluble solids content and titratable acidity at harvest and after four months of storage were not significantly different among the rootstocks.

Worldwide, Brazil holds the fifth position in melon fruits exportation, further expanding its products to provide for the growing demand. This expansion is the result of the development and application of new technologies, including the management of the use of biostimulants. However, for melon crops, the information in the literature on the use of biostimulants remains limited to the effects of different doses on fruit quality at the time of harvest. Therefore, this study aimed to evaluate the influence of different methods of pre-harvest application of two biostimulants on the production and postharvest conservation of fruits of yellow melon cv. Iracema. The treatments consisted of a combination of three factors: two plant biostimulants (Crop Set® and Spray Dunger®), two application methods of the products (fertigation and spraying), and five times of postharvest storage (0, 14, 21, 28 and 35 days). An additional control treatment corresponded to plants without biostimulant application. The fruits were evaluated for production and physicochemical attributes: average mass, yield, flesh firmness, titratable acidity, soluble solids content, SSC/TA ratio, pH, total soluble sugars, and weight loss. Fertigation is the recommended application method of biostimulants for yellow melon due to its effect on the increase of average mass, yield, flesh firmness, soluble solids content, and total soluble sugars of the fruits in relation to the spraying method.

The aim of this study is to investigate the effect of sunburn injury on fruit quality parameters (colour-coverage, depth of affected tissue, fruit flesh firmness, soluble solids content) of apple.The symptoms of sunburn injury appeared in concentric ring shape, differed from each other and surface colour-coverage. This can be due to the ratio of the injury. The authors observed the following colours on the fruit surface (from the epicentre of the blotch on the transversal diameter of the fruit) dark brown (strongly affected), light brown (moderately affected), pale red transition (poorly affected), red surface colour-coverage (not affected).Sunburn of apple fruits is a surface injury caused by solar radiation, heat and low air relative humidity that in the initial phase results in a light corky layer, golden or bronze discolouration, and injuries to the epidermal tissue, in the surface exposed to radiation. Thus it detracts from its appearance, but in most cases, it would not cause serious damage to the epidermal tissue. The depth of affected tissue is not considerable, its values are between 1.5-2.0 mm generally. It is commonly known that the tissue structure of apple fruit is not homogeneous. Accordingly, the degree of injury shows some differences under the different parts of the fruit surface.On the basis of flesh firmness research, the authors established that the measure of flesh firmness of the affected part of apple fruit increases with the effect of sunburn. The consequence of this is the suffered plant cells will die, the water content of this tissue decreases and the fruit gets harder. This water-loss caused the increase of soluble solids content.

Maintaining plants in the field for two consecutive crop cycles is one of the latest techniques used by strawberry growers to reduce production costs. The goal of this research was to evaluate the postharvest fruit quality of six strawberry cultivars produced for two consecutive seasons with the same plants. They were planted from May to July 2010 under low-tunnel and fruits were evaluated in two growing seasons (season 1= January, February, and March 2011 and season 2= August, September, and October 2011), totaling three harvests of each cultivar in each year season. Fruits were picked up randomly among 500 plants of each cultivar, organized into five replications of five fruits and kept for three days before analysis under refrigeration (average temperature of 4°C). Variables analyzed were: soluble solids content, titratable acidity, soluble solids content/titratable acidity, flesh firmness, C vitamin content, sensory characteristics (sweetness, flavor, acidity, aroma, shape and flesh firmness), and mineral composition (Ca, Fe, K, Mg, Mn, Cu and Zn). 'Albion', 'Monterey' and 'San Andreas' showed good physical, chemical and sensory characteristics in both seasons. In general, fruits produced during the season 1 showed better physical, chemical and sensory characteristics than fruits produced in season 2. 'Palomar' and 'Portola' were better than the other cultivars concerning C vitamin content in both seasons. 'Palomar' showed higher potassium, calcium, magnesium, manganese and zinc levels, and 'Portola' showed higher calcium and iron levels.

Investigations were carried out in 2013. A. kolomikta cv. ‘Laiba’, ‘Lankė’, ‘Landė’, ‘Paukštės Šakarva’ fruits were picked at the technical maturity stage. The amount of dry matter, soluble solids and texture parameters were established in fruits after harvesting and during storage. Fruits stored for 8 weeks in controlled atmosphere chambers with different air parameters (No. 1–21 % O2, No. 2–0.5 % O2, No. 3–1 % O2, No. 4–1 % O2 and 1 % CO2). Dry matter, soluble solids and texture analysis were done biweekly. The amount of dry matter was determined by drying the samples to the constant mass at the temperature of 105 ºC. Soluble solids content was determined by the refractometric method. Fruit texture parameters were analysed by Texture analyser. The results of chemical analysis at harvest time showed that the biggest amount of dry matter and the highest value of flesh firmness were in ‘Laiba’ fruits, soluble solids in ‘Landė’ fruits. The highest value of bio-yield point was established in ‘Paukštės Šakarva’ fruits. Results of analysis showed that dry matter content as well as soluble solids content of A. kolomikta fruits increases during storage in controlled atmosphere chambers. The highest increase in soluble solids content was in chamber No. 4 and the highest increase in dry matter content was in chamber No. 2 compared with fruits at harvest time. A. kolomikta fruits texture changes during fruit ripening with bio-yield point and flesh firmness declining. The largest decrease of bio-yield point and flesh firmness of fruits occurred in two weeks of storage.
