“…Thus, cultivar Sweet Grape may have been influenced only by the rootstock Muralha. Mattedi et al (2011) stated that fruits with acidity higher than 0.32% are considered of excellent quality. In this study, results obtained for TAA were close to those reported by Loos et al (2009), ranging from 0.31 to 0.44%.…”

Studies have indicated that grafting increases yield and prevents plant diseases. An experiment was installed to evaluate the influence of rootstock on the physicochemical and phytotechnical characteristics of a cherry tomato cultivar (Sweet Grape) under organic, greenhouse production system, from July to December 2014. The experiment consisted of a randomized complete block design, with eight replications. Treatments were composed of four rootstocks (Emperador, Muralha, Enforce, and Enpower) and the ungrafted cultivar Sweet Grape (control). The following variables were analyzed: plant height, yield, firmness, discard, yield/discard ratio, total titratable acidity (TTA), total soluble solids (TSS), ratio, pH, number of clusters, and number of leaves. Data were subject to analysis of variance by the F test, at 5% significance level, and means were compared by the Tukey’s test. Plant height was significantly different among treatments. Rootstocks presented no significant differences on yield, number of clusters, and TTA. The rootstocks Emperador, Enforce, and Muralha presented significant difference when compared to the control. For number of leaves, all rootstocks were significant when compared to the control, but not in relation to each other. The rootstocks presented the following yields: Emperador = 66.57 t ha-1; Muralha = 59.79 t ha-1; Enpower = 58.44 t ha-1; Enforce = 57.92 t ha-1; and the control cv. Sweet Grape = 51.28 t ha-1. Results revealed that rootstocks have the potential to improve cherry tomato’s yield in an organic cultivation system and do not interfere negatively with the physicochemical quality of the final product.

“…The total soluble solids ranged from 2.8 (BGH 224, BGH 243, BGH 327 and BGH 349) to 6.16 o Brix (BGH 850). Mattedi et al (2011) and Marim et al (2009) found similar results by evaluating the diversity of tomato subsamples from BGH-UFV when they compared to the commercial cultivars. These authors verified high genetic variability among the subsamples, which demonstrates the possibility of selecting materials for several traits depending on the interest of the breeding program for both morpho-agronomic and quality traits.…”

The estimation of genetic diversity by qualitative, quantitative, and molecular data and their combination are important in characterizing germplasm collections for pre-breeding purposes, mainly for the identification of divergent parents. For this purpose, we assessed a population of 94 tomato subsamples from UFV Vegetable Germplasm Bank (BGH-UFV) using 10 ISSR markers and agronomic data (three qualitative and six quantitative traits). Data revealed the existence of genetic diversity in germplasm considering the three data classes. Principal coordinates analysis (PCoA) confirmed the genetic variability of the subsamples, explaining 27% of the variability in the first two PCoAs. The Bayesian based clustering analyses using the STRUTURE software verified the existence of a structured population, with three populations. The mantel test for the correlation produced by the three data classes showed highly significant correlation (r = 0.31, P<0.001) among quantitative and molecular data. The Tocher method of clustering for each dissimilarity matrices showed that the clustering patterns were dependent on the data classes. According to the results we found, it is possible to predict the best combinations of parents that can provide maximum gain in a breeding program. Besides the combine use of the quantitative, qualitative and molecular data, using multivariate and Bayesian method of clustering is an efficient method to study the genetic diversity of tomato plants in the germplasm bank.

“…There was a decrease in values from 7.1 to 5.3 in the palm 'Ear' and from 5.6 to 3.9 in the palm 'Tiny'. The results obtained for the ratio indicate that the minimally cladodes processed before incubation have a pleasant taste, since according to Mattedi et al (2011) the high value for the ratio allows for mild flavor, while low values, acid flavor.…”

The palm is a cactaceous of great global importance, being the young cladodes minimally processed a viable alternative consumption for cooking. Among the studied palm variables, enzymes play a major role in the post-harvest quality of these species, generating oxidation and influencing the sensory attributes of cladodes. Therefore, the objective was to estimate the pyruvate decarboxylase activity in young cladodes of 'Tiny' palms - Nopalea cochenilifera and 'Ear Mexican Elephant' - Opuntia tuna minimally processed. The experiment was conducted in the Laboratory of Chemistry, Biochemistry and Food Analysis Center of Science and Technology Agrifood the Federal University of Campina Grande, Campus Pombal, Paraíba. The young cladodes were minimally processed and the analyzes were performed immediately after processing, with 24 and 48 hours of incubation under controlled temperature (22 ± 2°C). The analyzes performed were activity of the enzyme pyruvate decarboxylase (PDC), pH, soluble solids, titratable acidity, ratio, soluble sugars, total chlorophyll, total carotenoids, ascorbic acid and phenolic compounds. There was enzymatic activity of pyruvate decarboxylase from young minimally processed cladodes for the species studied, with greater activity in the cladodes of the species 'Tiny'.
