extensive citrus triploid hybrid production by 2x×4x sexual hybridizations and parent-effect on the length of the juvenile phase.the citrus fresh market demands the production of seedless citrus fruits, as seedy fruits are not accepted by consumers. the recovery of triploid plants has proven to be the most promising approach to achieve this goal, since triploids have very low fertility, are generally seedless and do not induce seeds in other cultivars by cross pollination. triploid plants can be recovered by 2x×4x sexual hybridization. in this work, we present an effective methodology to recover triploid plants from 2x×4x ...201222614256

effects of chitosan coatings on physicochemical and nutritional quality of clementine mandarins cv. 'oronules'.a commercial solution of chitosan was applied on mandarins 'oronules' at different solid content (0.6%, 1.2% and 1.8%). additionally, one group of mandarins was coated with a polyethylene-shellac commercial wax, and another group remained uncoated (control). mandarins were stored at 5 °c up to 28 days followed by 7 days at 20 °c simulating retail conditions. one group of mandarins was stored at 20 °c for 9 days simulating direct retail conditions. the commercial wax decreased weight and firmness ...201222763670
carbohydrate control over carotenoid build-up is conditional on fruit ontogeny in clementine fruits.the final contents of primary and secondary metabolites of the ripe fruit depend on metabolic processes that are tightly regulated during fruit ontogeny. carbohydrate supply during fruit development is known to influence these processes but, with respect to secondary metabolites, we do not really know whether this influence is direct or indirect. here, we hypothesized that the sensitivity of clementine fruit metabolism to carbohydrate supply was conditional on fruit developmental stage. we appli ...201322882610

building and mining web-based questionnaires and surveys with sysq.a questionnaire is a method for collecting data that can come from many sources such as observations, telephone interviews or documentary sources. whatever the source of data is, the questionnaire provides a framework of questions that facilitate researcher's work. a manual approach for collecting data using questionnaire presents some limitations and introduces several sources of errors. a second issue regards the statistical and data mining of data that often is conducted using different tools ...201324307414
buffering growth variations against water deficits through timely carbon usage.water stresses reduce plant growth but there is no consensus on whether carbon metabolism has any role in this reduction. sugar starvation resulting from stomatal closure is often proposed as a cause of growth impairment under long-term or severe water deficits. however, growth decreases faster than photosynthesis in response to drought, leading to increased carbohydrate stores under short-term or moderate water deficits. here, we addressed the question of the role of carbon availability on grow ...201324348489
