“…6). A reduction over time was also observed for NAR, which is consistent with many previous studies (Karimi and Siddique, 1991;Lima et al, 2005;Antonio et al, 2017) and is commonly attributed to selfshading and an increase in the proportion of older leaves, resulting in lower photosynthetic rates per unit leaf area (Singh et al, 2009;Haque and Haque, 2016). Consistent with thinner leaves, the LV genotype exhibited a greater LAR than the other three genotypes under greenhouse as well as field conditions.…”

Morphological Traits Underlying Differences in Early Vigor among Four Cotton Genotypes

In comparison with other annual crops, cotton (Gossypium hirsutum L.) seedlings develop slowly after emergence. More rapid seedling development can provide advantages in limiting disease, insect, and weed impacts on cotton seedlings. Information on the mechanisms determining early vigor in cotton is limited. Therefore, three genotypes previously identified to differ in seedling vigor and one commercial cultivar were selected for detailed characterization of early growth in greenhouse and field conditions. Growing environment and genotype effects were significant for many of the measured traits. Environmental conditions prevailing in field and greenhouse conditions differentially affected seedling growth, including cotyledon biomass, root weight ratio (RWR), net assimilation rate (NAR), and specific leaf area (SLA). Genotypic differences were found in one or both environments for cotyledon area, area of the first leaf, total leaf area, and leaf, stem, root, and total biomass. Leaf weight ratio (LWR), stem weight ratio (SWR), RWR, LAR, and SLA differed among genotypes at most stages, but this was not the case for relative growth rate and NAR. The high‐vigor genotype generally had longer roots, larger cotyledons, greater cotyledon, stem, and total biomass, and greater SWR and RWR than the low‐vigor genotype. The low‐vigor genotype had the greatest LAR, SLA, and LWR among the four genotypes. Results obtained in this study suggest that factors such as the efficiency of photoassimilate conversion into biomass, energy density of the biomass, root carbon exudation, and/or photosynthetic rates differ between the low‐vigor and high‐vigor genotypes.

“…The levels found were in the ideal quality range for tomato fruits above 3.00 • Brix [43,44]. Antônio et al [45] found results close to this study, with values between 3.00 and 4.00 • Brix. However, Martins et al [46] revealed higher mean values above 4.40 • Brix, probably because they are indeterminate hybrids, which can be more effective in the deposition of sugars.…”

Can Soil Cover Affect the Performance, Yield, and Quality of Creeping Fresh Market Tomato Hybrids?

Soil cover is a major factor in the cultivation of creeping tomatoes, especially for in natura consumption. This study aimed to determine the combination of a suitable tomato hybrid and soil cover, resulting in superior production performance and quality attributes of tomato fruits. Tomato hybrids (Fascínio and Thaíse) were cultivated on five soil cover types (uncovered soil, plastic mulch, sorghum, Sudan grass, and pearl millet). The data were submitted to a principal component analysis (PCA), considering all the variables, through Biplot graphical analysis. A Pearson correlation analysis was performed at the 5% significance level. For biomass production, pearl millet and Sudan grass were distinguished from the other soil covers, showing lower decomposition rates and, consequently, longer half-lives. Covering with plastic mulch provided higher total (111 t ha−1) and commercial (74.4 t ha−1) yields, regardless of the analyzed hybrid. According to the PCA, soil cover management influences the production and quality of tomato fruits, except for chemical and post-harvest characteristics, and maintains ideal levels for commercialization for all treatments. The Fascínio hybrid presented better production attributes, higher total and commercial fruit production per plant as well as fruits with larger sizes, especially when grown in plastic mulch cover. The Fascínio hybrid also presented fruits with higher levels of bioactive compounds (lycopene and β-carotene).

Osmotic stress enhances fruit quality, including the dry matter content, in tomatoes (Solanum lycopersicum L.). This study aimed at providing further insight into the precision control of fruit yield and quality on the long-term moderate osmotic stress conditions in tomato fruit production. We compared the growth pattern between fruits of two cultivars, typical Japanese and Dutch cultivars, under two different nutrient concentrations (2.3 and 5.0 dS·m−1) to understand the effect of electrical conductivity (EC) on dry mass and water content of fruits. The experiment was performed with a rockwool bag culture system in a controlled greenhouse. Increasing EC resulted in an approximately 20% decrease in fruit yield and a 0.5–1% increase in fruit dry matter content in both cultivars. This yield reduction was not caused by the fruit number, but by an approximately 25% decrease in individual fresh fruit weight. Non-linear models were used to describe the changes in dry matter content, water content, and dry weight of tomato fruit as a function of cumulative temperature. The decay rate of dry matter content in the fruit decreased with high EC treatments in the Japanese cultivar. The points at which the rates of changes in water and dry weight increased the in fruit were around 585 and 480 °C-days after anthesis, respectively, under the low EC condition. Rates of water increase in the fruit were changed by high EC treatment, while the shifts were opposite with respect to the cultivars. Dry weight increase in the fruit was not affected by EC treatment. Collectively, our findings clarify the effect of EC on the fruit growth characteristics of Japanese and Dutch tomato cultivars, and provide new insights into the yield of high-Brix tomato cultivation.
