Abstract:
... Tocopherols are plant-derived isoprenoids with potent antioxidant activity, which have been implicated in the tolerance of plants to different stresses. However, tocopherol accumulation and biosynthesis in fruit, and their potential implication in postharvest chilling injury (CI), has been scarcely studied. Therefore, in this work, we have investigated tocopherol accumulation and biosynthesis in t ...

Abstract:
... Gray mold, caused by Botrytis cinerea, is an important cause of postharvest loss of strawberry fruit. In the present study, we found that benzyl-isothiocyanate (BITC), a natural compound widely existing in cruciferous vegetables with anti-cancer effect, was effective in controlling postharvest gray mold of strawberry fruit, and also strongly inhibited the natural decay of strawberry. The mode of a ...

Abstract:
... The dry rot of potato caused by Fusarium sulphureum is the main postharvest disease that causes serious economic loss and leads to mycotoxin contamination. Therefore, it is necessary to find a strategy to increase the plant’s resistance against disease. T-2 toxin at low concentration can act as an elicitor to induce resistance against disease. Calcium ion plays a vital role in induced resistance b ...

Infield pre-sorting is intended to remove processing-grade (inferior) fruit that are not suitable for the fresh market, so that growers can handle sorted apples differentially in postharvest storage and packing to achieve cost savings. To achieve this goal, we developed an apple infield grading and sorting system, in which fruit singulation, rotation, and transportation are achieved by using simpl ...
