Ho Chi Minh City, 31th March 2024 Student Tran Nguyen Hai Tho 1 ABSTRACT The study conducted at Nong Lam University’s Laboratory of Plant Integrated Biology focused on the influence of plant growth regulators (PGRs) on callogenesis and somatic embryogenesis in Paramignya trimera.
Over the course of the study from March to December 2023, the aim was to identify the optimal type and concentration of PGRs for effective callus formation and embryo development in this plant species. Initial experiments involved sterilizing seed explants with Javel solution and using different types of explants such as zygotic embryos, cotyledons, hypocotyls, and radicles. These explants were cultured on Woody Plant Medium (WPM) supplemented with various combinations of NAA and BA for callus induction, and later, for somatic embryo induction, explants were transferred to WPM with TDZ. The results highlighted that sterilization with 20% Javel solution for 20 minutes provided a 70% survival rate and a 44.79% germination rate for seeds.
Callus induction was most successful with zygotic embryo and cotyledon explants, showing an 86.75% formation rate, respectively, when cultured on WPM with 2.0 mg/l NAA and 0. These calluses were nodular, firm, and capable of embryo generation. Additionally, the study noted the formation of adventitious roots in some explants.For somatic embryo development, the highest success rate (88.89%) was achieved with young leaf callus cultured on WPM containing 0. However, higher concentrations of TDZ (0.3 mg/L) resulted in a higher rate of abnormal embryo development (83.
This research provides valuable insights into the conditions necessary for effective somatic embryogenesis and callogenesis in Paramignya trimera, potentially contributing to the conservation and propagation efforts for this species. Keywords: Callogenesis, Paramignya trimera, plant growth regulators, somatic embryogenesis, tissue culture. 1H TÓM TẮT Nghiên cứu được thực hiện tại Phòng thí nghiệm Sinh học tổng hợp thực vật của Đại học Nông Lâm tập trung vào ảnh hưởng của các chất điều hòa sinh trưởng thực vật (PGR) đến quá trình hình thành mô sẹo và tạo phôi soma ở cây Paramignya trimera. Trong suốt quá trình nghiên cứu từ tháng 3 đến tháng 12 năm 2023, mục đích là xác định loại và nồng độ PGR tối ưu để hình thành mô sẹo và phát triển phôi hiệu quả ở cây Paramignya trimera.
Các thí nghiệm ban đầu liên quan đến việc khử trùng mẫu hạt giống bằng dung dịch Javel và sử dụng các loại mẫu cấy khác nhau như phôi hợp tử, lá mam, trụ dưới lá mam và rễ mầm. Những mẫu này được nuôi cấy trên Woody Plant Medium (WPM) được bổ sung nhiều sự kết hợp khác nhau của NAA va BA dé tạo mô sẹo, và sau đó dé tao phôi soma, các mẫu được chuyền sang WPM bổ sung TDZ. Kết quả nhân mạnh rằng việc khử trùng bằng dung địch Javel 20% trong 20 phút mang lại tỷ lệ sống sạch là 70% và tỷ lệ nảy mầm của hạt là 44,79%. Việc tạo mô sẹo thành công nhất với các mẫu phôi hợp tử và lá mam cho thấy tỷ lệ hình thành lần lượt là 86,61% và 93,75% khi nuôi cấy trên WPM với 2,0 mg/l NAA va 0,2 mg/l BA.
Những mô seo này có dang nốt san, chắc và có kha năng tạo phôi. Ngoài ra, nghiên cứu còn ghi nhận sự hình thành rễ bat định ở một số mẫu mô sẹo. Ở nghiên cứu phôi soma, tỷ lệ phát triển phôi hình cầu cao nhất (88,89%) đạt được với mô sẹo lá non được nuôi cay trên WPM chứa 0,07 mg/L TDZ. Tuy nhiên, nồng độ TDZ cao hơn (0,3 mg/L) dan đến tỷ lệ phôi phát triển bat thường cao hơn (83,33%).
Nghiên cứu này cung cấp những hiểu biết có giá trị về các điều kiện cần thiết cho quá trình tạo phôi soma và hình thành mô sẹo hiệu quả ở Paramignya Trimera, có khả năng góp phần vào nỗ lực bảo tồn và nhân giống loài này. Từ khóa: Hình thành mô sẹo, Paramignya Trimera, chất điều hòa sinh trưởng thực vật, tạo phôi soma, nuôi cây mô. 1V CONTENT Trang ACKNOWLEDGEMENT.-- ----- - SH HH HH ng 1 DECLARATION OF AUTHORSHIP.22 re ii ASTER SPR OP ors ese EEE sree ees se en see ee 11 T KỆ TẾ Tu#n ga tiötraGarhditGtrötiiritGlsSuBdgSSGtrfijiytqtdiaudaGsingSaaggpiosasgl iv COIN TEE IN secondo ci ease eg ren Heiter etna V LIST OF ABBREVIATIONS. ege vii IIRSU9)59.

In oriental medicine, it is often called "Don Diep Dang Thich”. In the human world, it is called the "re moi" plant or the "than xa" plant. Ð trimera has high medicinal value and is an important medicine in traditional medicine because it contains groups of rare substances such as coumarin triterpenoids, flavonoids, saponins, alkaloids, and glycoside derivatives. These groups of substances have been shown to have anti-inflammatory effects, treat liver disease and diabetes, and help repel many cancer cell lines.
It is because of the excellent effect of P. trimera in the treatment and reverse of cancer that, in recent years, the price of Ð trimera has been inflated. Therefore, this medicinal plant is being hunted by people and exploited to the point of exhaustion to make medicine, so its distribution range is increasingly narrowed and in danger of extinction in the wild if no measures are taken for effective conservation. Therefore, in the current market of P.
