Caracterização física e química dos frutos nos diferentes quadrantes da planta e germinação de sementes do portaenxerto cítrico tangerineira ‘sunki’

The tangerine 'Sunki' are highly relevant for the Brazilian citrus industry by presenting important traits for genetic improvement and to be considered a great portaenxento. In this context, the objective of the present work to study the characterization of the fruits of citrus rootstock 'Sunki', depending on the position on the plan and also the germination of their seeds. The physical characteristics evaluated were fruit weight, longitudinal and equatorial diameters of the fruit longitudinal diameter / equatorial diameter, number of buds per fruit, weight of buds and bark and number of viable seeds per fruit. As for the chemical characterization was evaluated titratable, acidity, soluble solid, "Ratio", pH and vitamin C. For the evaluation of these variables, the fruits were obtained from the northeast, southwest, northwest and southeast quadrants. Regarding the evaluation of seed germination, different doses of gibberellic acid and Stimulate were used. The seeds extracted from ripe fruit, washed, dried in the shade and stored in BOD. Immediately after, they were treated for 24 hours with plant growth regulators. After soaking, the seeds were placed in a germinator in germitest paper. After initiation of the germination process, the evaluations were performed daily until the thirty- fourth day. Fruits of 'Sunki'mandarin with uneven as the fruit position within the canopy, the use of gibberellic acid and growth promoter is promising for commercial use on seed germination of this rootstock.

Adubação nitrogenada e potássica em goiabeiras ‘paluma’: I. efeito na produtividade e na qualidade dos frutos para industrialização

The nutrition of the orchards is the major factor of productivity, being necessary to know the proper doses of fertilizers and their influence on fruit quality attributes for industrialization. This study evaluated the effects of different doses of nitrogen and potassium on the productivity of guava trees and also on the values of pH, soluble solids (SS), titratable acidity (TA) and pulp/kernel ratio of guavas. The experiment was conducted at Vista Alegre do Alto, SP in an irrigated 'Paluma'guava orchard, 7 years old, managed with pruning during three consecutive cycles of production. The soil of the area was dystrophic Ultisol. The experimental design was the randomized blocks, in factorial, with four nitrogen doses (0, 0.5, 1 and 2 kg of N plant(-1)) and four of potassium (0, 0.55, 1.1 and 2.2 kg of K2O plant(-1)), with three replications. Nitrogen fertilization increased productivity and the pH of the fruit, being explained by the quadratic polynomial regression models; reduced linearly the pulp/kernel ratio and do not influenced the SS and TA values. On the other hand, potassium fertilization and N x K interaction had no significant effects on productivity and the other characteristics evaluated.

Qualidade de cebola minimamente processada em diferentes tipos de cortes

The high perishability of the onion has limited its conservation period and caused great post-harvest losses. The need of consuming fresh products has led the market of minimally processed products to considerably rise. Cut operations during the minimal processing may not only cause important biochemical reactions in the onion tissues, but also affect its sensorial quality, resulting in a drastic reduction in the post-harvest life of the product. In this study the influence of different cut types was assessed on the quality of minimally processed onions. 'Baia Periforme'onions were transported to the laboratory, where they were selected, cleaned, classified, peeled, minimally processed into slices, grated and chopped, and subsequently sanitized for 10 minutes in sodium hypochlorite at 100 mg L-1. The product was kept on polystyrene trays covered with plastic film (PVC) as 80 g portions and conserved in a cold chamber at 5 +/- 1 degrees C and 85 +/- 5% RH, during 6 days. Physical, chemical and physico-chemical assays were carried out. Statistical design was completely randomized with 3 treatments and 3 replications (plot group) and 5 replicationss for the control group. For sensorial analysis (aspect and smell), 10 replications were used. To compare means, Tukey test at 5% significance was adopted. During the refrigerated conservation, sliced onions kept more stable levels of soluble solids, titratable acidity, total sugars, reducing and non-reducing sugars. The grated onion was superior considering the sensorial characteristics, indicating that the cut types interfered in these features and the grated onion was more accepted by evaluators.
