Đánh giá sự biểu hiện một số gen liên quan đến sự ra hoa ở cây cúc Farm (Chrysanthemum morifolium) dưới điều kiện chiếu sáng bổ sung ánh sáng LED đỏ

Nghiên cứu này giúp lựa chọn được nguồn sáng và thời gian chiếu sáng bổ sung phù hợp giúp giảm chi phí năng lượng, tăng hiệu quả kinh tế. Dưới điều kiện chiếu sáng LED đỏ 660 nm với thời gian chiếu sáng 1-2 h/1 đêm, cây cúc Farm có được hiệu quả kìm hãm quá trình ra hoa tương đương với đèn compact truyền thống. | TNU Journal of Science and Technology 226 10 129 - 137 EVALUATION OF THE EXPRESSION OF FLOWERING GENES OF CHRYSANTHEMUM FARM Chrysanthemum morifolium UNDER RED LED ADDITIONAL LIGHTING CONDITION Hoang Thi Huyen Trang1 Tran Thi Huyen1 Nguyen Quang Tru1 Pham Bich Ngoc1 Chu Hoang Ha1 Do Tien Phat1 Do Thi Gam2 Phan Hong Khoi2 Nguyen Van Thao2 Nguyen Thi Thu2 Phan Thi Lan Anh2 Nguyen Ba Nam3 1Institute of Biotechnology - Vietnam Academy of Science and Technology 2Center for High Technology Development - Vietnam Academy of Science and Technology 3High-tech Agricultural Research and Application Institute - Dalat University ARTICLE INFO ABSTRACT Received 18 5 2021 To prolong the growth period and inhibit the early flowering of commercial chrysanthemums this study used artificial light sources. In chrysanthemum Revised 11 6 2021 cultivation there are two lighting methods supplemental lighting to prolong Published 21 6 2021 the day and flash lighting to break the night. This study helps to select the appropriate light source and additional lighting time to reduce energy costs and KEYWORDS increase economic efficiency. Under 660 nm red LED supplement lighting conditions with a lighting time of 1-2 h night chrysanthemum plants have the Light same effect of inhibiting flowering as traditional compact lights. Expression Chrysanthemum Farm levels of CO TFL genes were recorded through quantitative RT-PCR with specific primer pairs. In the supplement lighting group the TFL gene the gene Gene CO that inhibits flowering was expressed times more than that while the Gene TFL expression of CO gene the gene that induces the buds was inhibits times LED less than that compared to non-lighting group. This result is a premise for further studies on gene expression evaluation of chrysanthemum varieties in Vietnam.
