The objective of this study was to evaluate the efficiency of pre-harvest application of 1-methylcyclopropene?-cyclodextrin in concentrated magnesium sulfate solution (1-MCP; Harvista? 1.3 SC) to delay maturation of ?Cripps Pink? apple fruit. 1-MCP was sprayed at 0, 75, 150, 225 and 300 mg L? 1 , seven days before the anticipated harvest time (DBAH). Aminoethoxyvinylglycine (AVG, 124 mg L? 1 , Retain®) was sprayed 28 DBAH, as a commercial control treatment. Fruit maturation was delayed by increasing 1-MCP concentration. 1-MCP at concentrations ? 150 mg L? 1 delayed by six and 15 days the time for the fruit to reach the harvest firmness of 71.1 N and 66.7 N, respectively, compared to untreated fruit. Skin color changes (red color development and background degreening) were inhibited by increasing 1-MCP concentrations up to 300 mg L? 1 . The reduction of ethylene synthesis, and the loss of flesh firmness and starch content occurred by increasing 1-MCP concentrations up to 98.2, 134.5 and 182.3 mg L? 1 , respectively. The AVG treatment delayed ethylene production and skin red color development at harvest more markedly than the highest concentration of 1-MCP (300 mg L? 1 ). However, both treatments (AVG and 1-MCP at 300 mg L? 1 ) had late harvested fruit (28 days after spraying 1-MCP) with percentage of skin red color below 40%. The results show that 1-MCP delays maturity, but concentrations ?135 mg L? 1 do not improve its efficacy on preserving flesh firmness while might inhibit skin red color development in ?Cripps Pink? apples.

Driven by the environmental stress caused by plastics, the interest on eco-friendly polymers has attracted the attention of researchers and industry. Thermoplastic starch (TPS) and poly (ε-caprolactone) (PCL) blends are good examples of sustainable material, exhibiting synergism between economic viability and properties. However, its biodegradability aligned to nutrients release has been less explored in agricultural applications. Herein, it is proposed the investigation of biodegradability of urea plasticized TPS and PCL blends, compatibilized with PCL grafted with maleic anhydride (PCL-g-MA), aiming fertilizers and sustainable agricultural products. The blends were prepared in a twin-screw extruder using a flat film die. The mechanical, thermal, morphological, and physical properties of TPS-PCL films were characterized, including biodegradation analysis via Bartha respirometer and nitrogen release in the soil. The films presented biodegradability and nitrogen release as a function of TPS content on blends formulation, presenting flexibility and robust mechanical properties. These findings may open a way of multifunctional agricultural products applied as fertilizer materials through economical and sustainable mulching films. |
