The Impact

Consumer concern about poor taste of fresh apricots is increasing and knowledge about the more suitable production requirement is essential. Genetic component influencing apricots quality is well known. However, there is limited information on environmental effect on fruit quality. This study aims to evaluate influence of altitude on phenological and fruit quality characters of apricot genotypes. Fruits from 162 genotype were collected from nine locations from 3006-3346 m asl in trans-Himalaya. The altitude had a marked influence on date of flowering, fruit weight, moisture and TSS content. For every 100 m increase in altitude, flowering and fruit ripening delayed by 3.3 and 7.1 day, respectively. Inverse relationship between altitude and fruit weight (R2=0.310) was observed. For every 100 m increase in altitude the fruit weight decrease by 0.5 g. Fruit moisture content decreased significantly with increase in elevation (R2=0.585). Decrease in moisture content was 1.9% for every 100 m increase in elevation. Altitude showed linear relationship with fruit TSS content (R2=0.726). For every 100 m increase in altitude, the fruit TSS increased by 1.2ºBrix. Knowledge from the present study on the impact of altitude on fruit quality characters provides a useful guide for selecting orchard location towards improving fruit quality

Prunus Armeniaca L

Specific productivity and some correlations between growth and productivity were evaluated in a set of 24 apricot (Prunus armeniaca L.) genotypes in 1994&ndash;1999. Even though the planting stock came from the same nursery, was of even age and on the same rootstock, the tree size of genotypes varied from planting to a permanent site. Differences in the tree size of genotypes slightly diminished over the six-year period, likely under the influence of uniform pruning used for all trees. Nevertheless, tree size evaluated from the area of stem cross-section can be considered as a genotype disposition. It is proved by a positive, highly significant correlation (r = 0.84<sup>++</sup>) between the rank genotypes according to the area of stem cross-section in the fourth and eleventh year after planting. Confidence intervals also confirmed significance of differences in specific productivity. In total, specific productivity of twelve genotypes was significantly higher than in the control cultivar Velkopavlovick&aacute;. A negative, significant moderate correlation (r = &ndash;0.40<sup>+</sup>) was calculated between tree size and specific productivity expressed as yield weight per unit area of stem cross-section. Weakly growing genotypes had higher specific productivity. The highest specific productivity was recorded in cultivars Vynoslivyj and Priusadebnyj and in LE-1321 and LE-390 hybrids. Of them, the most interesting for producers and fruit quality was Vynoslivyj with average fruit weight 47 g and harvest ripeness 11 days after Velkopavlovick&aacute;.

The Impact

Irrigation is a major activity in arid and semi-arid regions for many crops, including orchards. The deficit irrigation is an alternative in the context of global warming. The crop studied was apricot, 'Orizont' cultivar, 16 years old, grafted on the 'Constanta 14' rootstock. The planting distance was 4 m between the rows and 5 m between trees in the row. Fruit size and weight are important qualities and yield traits in apricot (Prunus armeniaca L.), but the factors that influence fruit size and weight remain to be explored. The fruit biometrical characteristics was influenced by the irrigation regime, with the irrigated treatment with 100% AHI (T1) showing significantly (P <5%) higher differences versus T2 and T3. As with fruit biometrical characteristics, the fruit weight determined on the fruits of the studied treatments had the same trend. In this study, we investigated the impact of stress hydric on fruit size and weight at 'Orizont' apricot cultivar in 2019-2020 period.

Fruit Quality Traits

Abstract Apricot (Prunus armeniaca L.) is a world-wide highly appreciated fruit, with its attractive colour, soft texture and typical flavour. In the current investigation, 68 apricot accessions collected from Jammu and Kashmir, India were analysed to determine the measure of variation using 12 qualitative and 16 quantitative traits with an aim to identify superior apricot accessions with excellent fruit quality traits. High phenotypic variability was observed among the studied apricot accessions with significant differences among most of the qualitative and quantitative traits. Fruit-related characteristics including fruit weight, fruit length, fruit ratio, fruit firmness, fruit shape, fruit suture, stone weight, kernel weight and stone shape were the most diverse with a high coefficient of variation (>30%). One way analysis of variance showed significant differences (P < 0.0001) among all the quantitative traits. Significant positive and negative correlations were observed between all the agronomically important fruit quality traits. The principal component analysis (PCA) revealed that 75.34% of the variability was defined by the first eight components. The unweighted pair group method with arithmetic mean (UPGMA) dendrogram, based on all traits measured grouped the accessions into two main clusters with several sub-clusters. Both UPGMA dendrogram and PCA scatter plot formed a cluster of 14 accessions, having the highest values regarding most important fruit quality traits such as fruit weight, fruit length and width, fruit ratio, stone weight and kernel weight can be treated as potentially superior accessions. These accessions can be used directly for cultivation and in future apricot breeding programmes. The present findings are promising for genetic resource management, cultivar improvement and commercial applications of apricot in Jammu and Kashmir, India.

The Difference

This study presents results on the performance of apricot (Prunus armeniaca L.) genotypes in Central Serbia. The research included observation and recording of biological (i.e. phenological) traits and in situ sampling of fruits from 1,210 grafted trees for determination of pomological and sensorial traits. A total of 14 genotypes were selected and compared with Hungarian Best (control cultivar). The difference in blossoming time between two years was one month. In 2006, blossoming time was found to be earlier in three genotypes, simultaneous in five genotypes and later in six as compared to the control. In 2007, bloom was earlier in four genotypes, simultaneous in four and later in six genotypes. Average fruit weight ranged from 41.34 &plusmn; 0.8 to 81.50 &plusmn; 4.1 g, T-5 being the only genotype having the fruit weight lower than Hungarian Best (49.07 &plusmn; 2.2 g). The content of soluble solids, total sugars, and mineral matter ranged from 15.72&ndash;18.88%, 11.53&ndash; 4.99%, and 0.29&ndash;0.43%, respectively, and total acidity was 0.77&ndash;1.08%. The appearance and the skin colour of the genotypes were highly attractive. They have promising traits which suggest that they can be useful parents in apricot breeding programmes.

The Impact

AbstractBackgroundIntensive agricultural practices have reduced soil health thereby negatively impacting crop yields. There is a need to maintain healthy soils and restore marginal lands to ensure efficient food production. Biochar, a porous carbon-rich material generated from pyrolysis of various feedstock sources is receiving attention as a soil amendment that has the potential to restore soil organic carbon content and also enhance crop yields. However, the physical and chemical properties of biochar are influenced by pyrolysis parameters. These in turn determine its interaction with the soil, thereby influencing its biological properties in terms of impact on soil microcosm and plant productivity. While most studies report the evaluation of one biochar and a single plant cultivar, the role of the plant’s genetic background in responding to biochar as a soil amendment remains unanswered. The impact of six distinct biochars on agronomic performance and fruit quality of three genetically diverse tomato (Solanum lycopersicum) cultivars was evaluated to test the hypotheses that 1) biochars derived from different feedstock sources would produce unique phenotypes in a single cultivar of tomato, and 2) single feedstock-derived BC would produce different phenotypes in each of the three tomato cultivars.ResultsDifferent biochars impacted shoot dry weight, total fruit weight, and yield per plant in each cultivar differently. Both positive and negative effects were observed depending on the biochar-cultivar combination. In ‘Oregon Spring’, Ryegrass straw and CoolTerra biochar enhanced yield. In ‘Heinz’, an increase in fruit weight and citric acid was observed with several of the biochars. In ‘Cobra’, improved yields were accompanied by reduction in fruit quality parameters. Both hypotheses were supported by the data.ConclusionsThis study demonstrated that the genetic background of a plant is an important variable in determining the outcome of using biochar as a soil amendment. Strategies for application of biochar in agricultural production should consider the variables of soil type, feedstock source, pyrolysis parameters and plant genetic background for enhancing crop productivity and carbon sequestration.
