“…A coefficient of determination ( R 2 ) of 0.88 was achieved, but again the model was not tested on independent fruit populations. Most recently, Radzevicius et al [ 20 ] reported the use of the luggable NIR Case NCS001A (Sacmi Imola S.C., Italy) for estimation of tomato DM, SSC, and firmness, but calibration statistics were not presented.…”

The utility of a handheld visible-short wave near infrared spectrophotometer utilising an interactance optical geometry was assessed in context of the noninvasive determination of intact tomato dry matter content, as an index of final ripe soluble solids content, and colouration, as an index of maturation to guide a decision to harvest. Partial least squares regression model robustness was demonstrated through the use of populations of different harvest dates or growing conditions for calibration and prediction. Dry matter predictions of independent populations of fruit achieved R2 ranging from 0.86 to 0.92 and bias from −0.14 to 0.03%. For a CIE a⁎ colour model, prediction R2 ranged from 0.85 to 0.96 and bias from −1.18 to −0.08. Updating the calibration model with new samples to extend range in the attribute of interest and in sample matrix is key to better prediction performance. The handheld spectrometry system is recommended for practical implementation in tomato cultivation.

“…Levels of total soluble protein were lower in immature green fruits compared to leaves, and declined further in all lines as ripening progressed ( Supplementary Figures S7 and S8 ). Gels for Fld detection were therefore loaded on the basis of FW, considering that unlike protein levels, the fraction of dry matter did not change significantly between tomato ripening stages (Matsuda and Kubota, 2010; Radzevičius et al, 2016). Figure 5A shows that mature-sized Fld was expressed in the green pericarp of immature Slpfld and Slcfld fruit.…”

Expression of a Chloroplast-Targeted Cyanobacterial Flavodoxin in Tomato Plants Increases Harvest Index by Altering Plant Size and Productivity

Tomato is the most important horticultural crop worldwide. Domestication has led to the selection of highly fruited genotypes, and the harvest index (HI), defined as the ratio of fruit yield over total plant biomass, is usually employed as a biomarker of agronomic value. Improvement of HI might then result from increased fruit production and/or lower vegetative growth. Reduction in vegetative biomass has been accomplished in various plant species by expression of flavodoxin, an electron shuttle flavoprotein that interacts with redox-based pathways of chloroplasts including photosynthesis. However, the effect of this genetic intervention on the development of reproductive organs has not been investigated. We show herein that expression of a plastid-targeted cyanobacterial flavodoxin in tomato resulted in significant reduction of plant size affecting stems, leaves, and fruit. Decreased size correlated with smaller cells and was accompanied by higher pigment contents and photosynthetic activities per leaf cross-section. Flavodoxin accumulated in green fruit but declined with ripening. Significant increases in HI were observed in flavodoxin-expressing lines due to the production of higher fruit number per plant in smaller plants. Therefore, overall yields can be enhanced by increasing plant density in the field. Metabolic profiling of ripe red fruit showed that levels of sugars, organic acids, and amino acids were similar or higher in transgenic plants, indicating that there was no trade-off between increased HI and fruit metabolite contents in flavodoxin-expressing plants. Taken together, our results show that flavodoxin has the potential to improve major agronomic traits when introduced in tomato.

“…Impact of tomato hybrid (the factor B) and environment (weather conditions: the factor A: A1 = 2011, A2 = 2012, A3 = 2013) on dry matter content -DM ( The highest dry matter content was determined in 2013 in all hybrids, and the lowest in the year 2012 of research. The total dry matter content in various tomato genotypes varied from 4.0% to 7.5% of fruits fresh weight (RADZEVIĈIUS et al, 2016). In the three-year study the highest dry matter content was recorded in hybrid Rally compared to standard hybrid.…”

The comparative estimation was carried out with seven tomato hybrids (Lycopersicon esculentum Mill.) during the period 2011 to 2013 in greenhouse at Agricultural Institute of Republic of Srpska, Banja Luka, Bosnia and Herzegovina. The aim of this study is to examine the dry matter content, lycopene in fruits and total yield of Dutch tomato hybrids in the conditions of western Bosnia and Herzegovina. The experiment was set up by a randomized block design in three repetitions. The dry matter content ranged from 5.60% to 8.14%. Hybrid and hybrid x year interaction had significant (p<0.05) influence on lycopene content and tomato yield. The factors that had a decisive influence on the content of dry matter, lycopene content in fruit and tomato yield were year, hybrid and cultivation technology.
