Consumption of bell peppers is recommended because of their bioactive compound content and their positive effects on health. Growth-promoting rhizobacteria are popular because of their ability to promote plant growth by improving the fixation of nutrients or by inducing a systemic response. Green bell pepper (Capsicum annum) roots were inoculated with an autochthonous strain of Bacillus amyloliquefaciens, at different stages of development: T1, inoculation in the seedbed before transplant; T2, inoculation at and after transplant; T3, inoculation in the seedbed, at and after transplant. Bell pepper plants without inoculation were considered as control. Physicochemical composition and antioxidant activity of the fruits were measured to select the best treatment.
T1 increased crude proteins, fat, Ca, Fe, vitamin C, total phenolic content, antioxidant capacity by DPPH and by ORAC. On the other hand, T1 decreased reducing sugars, K and Cu content. No significant differences for total carbohydrates, ash and photosynthetic pigments were found.
Inoculated green bell peppers have enhanced its functional value and could be considered as an important source of bioactive compounds with elevated antioxidant activity. © 2019 Society of Chemical Industry.
由于彩椒含有生物活性化合物，对健康有益，因此推荐食用。促生长根瘤菌因其能够通过改善养分固定或诱导系统反应来促进植物生长而广受欢迎。绿甜椒（Capsicum annum）根在不同的发育阶段（T1、T2 和 T3）用解淀粉芽孢杆菌的土著菌株进行接种：T1，在移栽前的苗床中接种；T2，在移栽时和移栽后接种；T3，在苗床、移栽时和移栽后接种。未接种的甜椒植株被视为对照。为了选择最佳处理方法，测量了果实的理化成分和抗氧化活性。
T1 增加了粗蛋白、脂肪、Ca、Fe、维生素 C、总酚含量、DPPH 和 ORAC 的抗氧化能力。另一方面，T1 降低了还原糖、K 和 Cu 的含量。总碳水化合物、灰分和光合色素没有显著差异。
接种的绿甜椒提高了其功能价值，可被视为具有较高抗氧化活性的生物活性化合物的重要来源。© 2019 英国化学学会。
