| Abstract:The objective of this work was to evaluate the effect of abscisic acid, applied at different rates and different fruit developmental stages, on the thinning of 'Chiripá' peach. Abscisic acid (ABA) at 500 mg L-1 was applied at three stages of fruit development based on lignin deposition: stage 1, at 24 days after full bloom (DAFB); stage 2, at 40 DAFB; and stage 3, at 52 DAFB. Only ABA application at stage 2 - 40 DAFB - reduced fruit set and the number of fruit per plant. Three ABA concentrations (350, 500, and 750 mg L-1) were then applied at 40 DAFB. All rates increased fruit ethylene production and fruit abscission. |

| Abstract: The objective of this work was to evaluate the effect of thinning with metamitron on the fruit yield and quality of 'BRS Kampai' peach (Prunus persica) trees. The experiment was carried out in the municipality of Eldorado do Sul, in the state of Rio Grande do Sul, Brazil, in the 2016 and 2017 crop years. Treatments consisted of the application of 100, 200, 300, and 400 mg L-1 metamitron and of hand thinning 40 days after full bloom, besides control plants. Fruit abscission, effective fructification, number of fruits, and fruit yield per plant were evaluated. Regarding fruit quality, fresh fruit biomass, epidermis color, pulp firmness, soluble solids, total phenolic compounds, and antioxidant activity were assessed; fruits were also classified... |

| The Florida Department of Citrus (DOC) is spending public funds to register an abscission agent compound (CMNP) with the U.S. EPA as part of its effort to enhance the private benefits associated with citrus mechanical harvesting. An abscission agent application should allow existing harvesting equipment to operate through the entire late season orange harvesting period. When estimating costs and benefits through 2018, the net present value of mechanically harvesting 25,000 acres is between $60.8 and $79.9 million, depending on price, production, and fruit loss scenarios. For any of the scenarios considered, the discounted value of abscission benefits with mechanical harvesting fully pays for the costs of registration and development within four years. |

| This work had the goal to evaluate the influence of temperature and dry storage on the postharvest longevity of Epidendrum ibaguense flowers previously treated with silver thiosulfate (STS). The flowers were harvested and pulsed for 30 minutes with 2 mM STS. Then both, the STS treated and untreated flowers were packed in perforated low density polyethylene bags, packed in cardboard boxes and stored at 5 and 10°C, where they remained for four and eight days. After this period, the flowers were kept in vase with distilled water at 25ºC, and analyzed at every 24 h. The experiment was arranged in a complete random design 2 x 2 x 2 factorial scheme, with four replicates, containing four inflorescences each, except for the determination of transpiration and... |

| Cold storage allows citrus budstick conservation for several months, although gradual bud viability loss and abscission of leaf petioles is observed. This study aimed to maintain bud viability reducing leaf petiole abscission in budsticks of 'Baianinha' and 'Valencia' sweet oranges (C. sinensis Osbeck), 'Tahiti' lime (C. latifolia Tanaka), and 'Murcott' tangor (C. sinensis × C. reticulata), using NAA, GA3, 2,4-D, and low temperature storage. After a 15-minutes-immersion in distilled water and NAA and GA3 solutions at concentrations of 10, 100, 500 and 1000 µmol L-1, and 2,4-D solutions at concentrations of 1, 10, 50 and 100 µmol L-1, the shoots were stored in polyethylene bags at 5 ± 1ºC for 74 days. Percentage of leaf petiole abscission, fresh and dry... |

| Citrus is the main fruit tree crop in the world and therefore has a tremendous economical, social and cultural impact in our society. In recent years, our knowledge on plant reproductive biology has increased considerably mostly because of the work developed in model plants. However, the information generated in these species cannot always be applied to citrus, predominantly because citrus is a perennial tree crop that exhibits a very peculiar and unusual reproductive biology. Regulation of fruit growth and development in citrus is an intricate phenomenon depending upon many internal and external factors that may operate both sequentially and simultaneously. The elements and mechanisms whereby endogenous and environmental stimuli affect fruit growth are... |
