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

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
