Bài báo nghiên cứu tác động của nano bạc (AgNPs) lên sự tái sinh chồi, khắc phục hiện tượng bất thường, sự biến động khí ethylene (ET) và hoạt tính enzyme chống ôxy hóa trong giai đoạn tái sinh chồi của cây African violet. Kết quả cho thấy, mẫu gân lá chính cho hiệu quả tái sinh chồi tối ưu hơn so với mẫu lá nguyên với tỷ lệ tái sinh chồi 66,00%, 5,33 chồi/mẫu và chiều cao chồi 0,73 cm sau 8 tuần nuôi cấy...

This article investigated the effects of silver nanoparticles (AgNPs) on shoot regeneration, abnormal growth, ethylene (ET) gas fluctuations, and antioxidant enzyme activity during the shoot regeneration of African violet. The results showed that using the main leaf vein explant significantly improved shoot regeneration efficiency compared to the whole leaf explant, with a shoot regeneration rate of 66.00%, an average of 5.33 shoots per explant, and shoot heightreaching 0.73 cm after eight weeks of cultivation...
