摘要:

为探究氧化石墨烯作为新型纳米材料对植物生长发育和果实品质的影响,以Micro-Tom番茄为研究对象,测定其在不同氧化石墨烯浓度水平下的种子萌发率、幼苗株高与茎粗、光合作用效率、果实产量、抗氧化酶活性,以及可溶性固形物、番茄红素、维生素C含量等内含物质积累情况,并评估氧化石墨烯应用于农林业领域的安全性。结果表明,氧化石墨烯质量浓度为50,100,200 mg/L时均能促进种子萌发并提高种子萌发率和胚根长度,其中,氧化石墨烯质量浓度为200 mg/L时效果最佳。氧化石墨烯质量浓度为50,100 mg/L时还可有效增加植株生物量,提升光合作用效率,增强植株内抗氧化酶活性,同时提高单果鲜质量和产量。尤为重要的是氧化石墨烯质量浓度为50 mg/L时还可显著提升果实维生素C含量,证实其具有改善番茄果实营养价值的潜力。安全性评估结果显示,氧化石墨烯处理后的番茄植株各组织中均未检测到氧化石墨烯的存在,表明其在促进番茄植株生长的同时并无显著残留,具有良好的生物安全性。因此,适宜质量浓度的氧化石墨烯(50 mg/L)可作为一种高效且相对安全的植物生长促进剂,实现番茄产量与果实品质的协同提升。

Abstract:

In order to analyze the effects of graphene oxide(GO),a novel nanomaterial,on plant growth,development,and fruit quality,Micro-Tom tomato was used as the model plant.Parameters measured included seed germination rate,seedling height,stem diameter,photosynthetic efficiency,fruit yield,antioxidant enzyme activities,and the accumulation of internal fruit components such as soluble solids content,lycopene,and vitamin C under varying GO concentration levels.The safety implications of GO application in agriculture and forestry were also evaluated.The results indicated that GO concentrations of 50,100,200 mg/L significantly enhanced seed germination rate,promoted germination,and increased radicle length,with the most pronounced effect observed at 200 mg/L GO.Concentrations of 50,100 mg/L GO exhibited significant positive effects:effectively increasing plant biomass,improving photosynthetic efficiency,enhancing antioxidant enzyme activities within the plants(contributing to the maintenance of redox homeostasis),and simultaneously elevating single-fruit fresh weight and overall yield.Notably,50 mg/L GO significantly increased fruit vitamin C content,directly demonstrating its potential to enhance the nutritional value of tomato fruits.Meanwhile,no detectable accumulation of GO was found in any tissues of the treated tomato plants.This finding provides critical evidence for assessing the biosafety of GO,preliminarily indicating that its plant growth promotion occurred without significant concomitant accumulation.Therefore,an appropriate concentration of GO,particularly 50 mg/L,can function as an efficient and relatively safe plant growth promoter,achieving synergistic improvements in tomato yield and fruit quality.
