Abstract
Boric acid (BA) is commercially acceptable and economically feasible material to enhance the shelf life of pears, oranges and other horticultural plants. Here, we investigated the effect of BA on the shelf life and post-harvest quality of table grapes (cv. ‘Kyoho’). The grapes were immersed in a BA solution with different concentrations [0 (as the control), 10, 30, 50 mM] for 10 min and stored at 25 ± 1 °C for 10 days. Compared to the control, the BA treatments maintained higher berry firmness by inhibiting the activity of polygalacturonase (PG) and cellulase. In addition, the BA-treated grapes maintained higher antioxidant enzyme activities, such as catalase (CAT) and superoxide dismutase (SOD), and lower metabolic toxic products, like the superoxide anion (O2-) production rate, malondialdehyde (MDA) and hydrogen peroxide (H2O2) content than the control. The experimental results showed that the post-harvest application of BA effectively delays the senescence of grapes compared with the control, and the 10 mM BA treatment had the most obvious effect.
硼酸(BA)是一种商业上可接受和经济上可行的材料，可以延长梨、橙子和其他园艺植物的保质期。在这里，我们研究了BA对鲜食葡萄的保质期和采后品质的影响。“Kyoho”)。将葡萄浸泡在不同浓度[0(作为对照)，10,30,50 mM]的BA溶液中10分钟，并在25±1 °C下保存10天。与对照相比，BA处理通过抑制聚半乳糖醛酸酶(PG)和纤维素酶的活性，保持了较高的浆果硬度。此外，与对照相比，ba处理的葡萄保持了更高的抗氧化酶活性，如过氧化氢酶(CAT)和超氧化物歧化酶(SOD)，以及更低的代谢毒性产物，如超氧阴离子(O2-)产量、丙二醛(MDA)和过氧化氢(H2O2)含量。试验结果表明，采后施用BA与对照相比，有效延缓了葡萄的衰老，其中10 mM BA处理效果最明显。
