“…That in turn could be the reason of further decrease in fruit yield. Our results were in agreement with the results of Gautier et al (2001) and the report of Galiński & Pietkiewicz (1987). They reported that, plants of Solanaceae family after reaching the harvest stage show irreversible changes in the assimilates distribution pattern towards plant organs which form the final yield.…”

SummaryTwo tomato morphotypes (cvs. Favorita, Organza and Azarro) of different fruit size were grown during 2005-2006 on a rockwool substrate under greenhouse conditions. Leaf area index (LAI), solar radiation absorption coefficient (TAO) and leaf area duration (LAD) were determined. Tested tomato cultivars proved different yielding strategies expressed by dissimilar values of the measured and calculated physiological indices (LAI, LAD, TAO and the canopy yielding efficiency). Cv. Organza showed the highest canopy yielding efficiency, cv. Azarro showed a negative dependence between LAD and yield, while cv. Favorita canopy architecture allowed to achieve better penetration of light energy to lower canopy layers and showed better tolerance of this cultivar to thermal stress.

“…In bare root ones, this pool is the main energy source for the emission and growth of new roots to replace those damaged at digging or cut off before planting. Nevertheless, new roots are not immediately able to absorb water and nutrients and plants are susceptible to stress in the days after planting (Gautier et al, 2001). In the strawberry plant, this phenomenon may be stronger than in other species, because it is considered as having a slow root growth (Hennion and Veschambre, 1997).…”

Strawberry (Fragaria x ananassa D.) yield is affected by vigor of transplants. Those young and vigorous at planting lead to plants reaching higher vegetative growth and fruit yield than weak or old ones. This study aimed at determining plant growth, development, and fruit yield of the strawberry plant from bare root and plug transplants with different crown diameters. Bare root transplants were produced by rooting stolons and plug transplants from runner tips collected and rooted in a substrate growing bed. Three classes of crown diameters were compared in a 2 × 3 factorial and randomized block experimental design, with four replications, 16 plants per plot and a density of 6.6 plants m -2 . For bare root transplants, crown diameters were between 3.0 and 5.0 mm (class 1); 5.1 and 8.0 mm (class 2) and greater than 8.1 mm (class 3). For plug transplants, runner tips were screened between 2.0 and 3.9 mm (class 1); 4.0 and 5.5 mm (class 2) and 5.6 to 7.0 mm (class 3). Transplants of both types were planted at April 16 th , 2008, and at this date, crown diameter, shoot and root dry mass and number of leaves were higher in all classes of plug transplants. Ripe fruits were harvested from June 15 th to November 7 th , 2008, and fresh fruit yield was determined. Plant growth and development were determined at last harvest. Higher growth, development and fruit yield were obtained in plants from plug transplants. For bare root transplants, crown diameters higher than 5.1 mm can be used while for plug transplants the crown diameter of runner tips does not affect plant growth and fruit yield.

“…That said, this population also harbored pathway QTLs linking branched-chain amino acids (lines C8e, C9d, C11d, and C12c) as well as the metabolites linking Glu metabolism and the tricarboxylic acid cycle (line C12c), similar to those previously described for the S. pennellii population, albeit not always at the same chromosomal location. Moreover, environmental conditions, including the exact practice of cultivation, are often described as determinants of fruit growth and quality (Heuvelink, 1997;Gautier et al, 2001;Bertin et al, 2003;Semel et al, 2007). Therefore, in this study, we attempted to evaluate the influence of all the above-mentioned parameters by assessing these features in the differently behaving S. chmielewskii introgression lines, IL C9d and IL C12d, and the parental line.…”

The Influence of Fruit Load on the Tomato Pericarp Metabolome in aSolanum chmielewskiiIntrogression Line Population

It has been recently demonstrated, utilizing interspecific introgression lines of tomato, generated from the cross between Solanum lycopersicum and the wild species Solanum pennellii, that the efficiency of photosynthate partitioning exerts a considerable influence on the metabolic composition of tomato fruit pericarp. In order to further evaluate the influence of source-sink interaction, metabolite composition was determined by gas chromatography-mass spectrometry in a different population. For this purpose, we used 23 introgression lines resulting from an interspecific cross between S. lycopersicum and the wild species Solanum chmielewskii under high (unpruned trusses) and low (trusses pruned to one fruit) fruit load conditions. Following this strategy, we were able to contrast the metabolite composition of fruits from plants cultivated at both fruit loads as well as to compare the network behavior of primary metabolism in the introgression line population. The study revealed that while a greater number of metabolic quantitative trait loci were observed under high fruit load (240) than under low fruit load (128) cultivations, the levels of metabolites were more highly correlated under low fruit load cultivation. Finally, an analysis of genotype × fruit load interactions indicated a greater influence of development and cultivation than genotype on fruit composition. Comparison with previously documented transcript profiles from a subset of these lines revealed that changes in metabolite levels did not correlate with changes in the levels of genes associated with their metabolism. These findings are discussed in the context of our current understanding of the genetic and environmental influence on metabolic source-sink interactions in tomato, with particular emphasis given to fruit amino acid content.
