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.

A 1% solution of antitranspirant and a 0.3% solution of vegetable oil were applied to cherry trees before rainfall during the 3 weeks preceding harvest to evaluate their efficacy in reducing fruit damaged by cracking in field experiments in South Australia from 1993 to 1998. Between 2 and 14% of fruit were cracked on untreated trees during this period. From 6 to 10% less cracked fruit were found in 2 of the 5 seasons following the application of antitranspirant and oil sprays. In the other 3 seasons, levels of cracked fruit were not significantly different between treatments. In the 2 driest seasons, treatment with oil or antitranspirant resulted in larger fruit than on untreated trees, and as in previous studies this was thought to be a result of reduced water loss. In 4 years, total soluble solids content of fruit were similar in all treatments, but in 1996–97 controls had significantly higher sugar levels than the treated fruit. This being the driest year during the study, it is thought that greater water loss occurred on controls leading to a higher concentration of total soluble sugars. Material costs of oil at A$96/ha per application is less, compared with antitranspirant that cost $4000/ha per application.

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.

Over the past several growing seasons researchers at Texas Tech University have observed that certain onions appeal to rabbits more than other onions, meaning that rabbits tend to nibble on certain lines or varieties and leave other lines undisturbed. We were interested in determining the cahracteristics of the onions that rabbits seemed to like. Onions were planted at random in the TTU breeding nursery. During the growing season all onions were rated for rabbit appeal - those with chewed leaves and or bulbs were recorded as liked by the rabbits. All onions in each plot, whether disturbed or undisturbed by the rabbits, were tested for pyruvate concentration and soluble solids content after harvest. Pyruvates were measured by mmol/gram pyruvic acid and soluble solids content by °Brix refractometer reading. The most damage occurred in onion lines that had the lowest pyruvate levels. Soluble solids did not appear to affect the rabbits' nibbling.

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.

“Ruaner” pear (Pyrus ussuriensis Maxim.) is a fruit crop that is frequently served frozen in China. It is a typical postharvest ripening fruit that needs to ripen after harvest before it can be eaten, and freezing–thawing is one way that pears are treated during postharvest ripening. In order to study the physical–chemical composition and quality-related changes in “Ruaner” pears that result the freezing–thawing period, “Ruaner” pears were kept in a freezer (−20 °C) for 7 days, after which they were transferred to room temperature for thawing. The color of the peel of the “Ruaner” pears changed from yellow-green to yellow and then brown. The chlorophyll content and titratable acidity (TA) decreased significantly throughout 0–12 h period. The carotenoid content tended to rise and then decrease, peaking at 3 h after thawing (HAT), while the soluble solids content (SSC), firmness, total phenolic content, and total flavonoid content all generally decreased. The composition of soluble sugars and organic acids was examined in “Ruaner” pears, and the major soluble sugars were fructose and glucose, with citric acid being the most abundant organic acid. The data suggest that freezing–thawing significantly changes firmness, water content, SSC, and TA in “Ruaner” pears. At 3–4 HAT, “Ruaner” pears have moderate hardness, high water content, low acid content, and higher total phenolic, total flavonoid, and soluble solids content. Therefore, 3–4 HAT is the best time for pears in terms of both table and processing quality.

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.

ABSTRACT: This study carried out agronomic evaluation and estimated the combining ability of tomato lines for the industrial segment, aiming to elect promising genotypes for breeding and to find simple hybrids with superior traits. Randomized-blocks design was used with 57 treatments (45 experimental hybrids, 10 lines and 2 checks treatments) with 3 replications. A complete diallel among 10 tomato lines for processing was used. Evaluated traits were: fruit total (YT) and commercial production (YC), pulp yield (YP), fruit average mass (MM) and total soluble solids content (TSS). Diallel crosses allowed synthesizing experimental hybrids with superior traits when compared to commercial hybrids. Non-additive effects prevailed over the expression of YT, YC, YP and TSS, whereas additive effects prevailed for MM. Lines RVT-08, RVT-05 and RVT-10 are most appropriate for intrapopulational breeding. Experimental hybrids RVT-08 x RVT-09, RVT-07 x RVT-10 and RVT-08 x RVT-10 were pointed as the experimental genotypes with the best performance, surpassing the commercial genotypes for the traits evaluated.
