Abstract

Oldenlandia herbacea (L.) Roxb. is an important medicinal plant of Indian, Malayan, and Chinese traditional systems of medicines. In vitro flowering system serves as a model system to study flowering physiology, and role of combination of photoperiodic conditions and ethylene inhibitors. Ethylene is responsible for delayed flowering response in plants; hence, it is interesting to explore the role of ethylene inhibitors and photoperiod on flowering mechanism. The present study, for the first time, reports the influence of silver thiosulfate (STS), silver nitrate, and photoperiod (PP) to induce high-frequency in vitro flowering in O. herbacea. The flowers were induced from the in vitro shoots (2.0 floral buds per shoot) on MS medium containing 4 μM 6-benzylaminopurine + 2 μM indole-3-acetic acid + 5 μM STS at 14-h PP. This study could be the foundation to understand the role of PP and silver ions on flowering physiology at molecular level.

光周期和银离子对玉兰离体开花的调控Roxb。
龙胆。是印度、马来亚和中国传统医药体系中的一种重要药用植物。体外开花系统是研究开花生理、光周期条件和乙烯抑制剂组合作用的模型系统。乙烯是植物延迟开花反应的原因;因此,探讨乙烯抑制剂和光周期在开花机制中的作用具有重要意义。本研究首次报道了硫代硫酸银(STS)、硝酸银和光周期(PP)对牛膝高频离体开花的影响。在含有4μM 6-苄基氨基嘌呤+2μM吲哚-3-乙酸+5μM STS的MS培养基上,以离体芽(每芽2.0个花蕾)为外植体,在14小时的PP下诱导开花。本研究为从分子水平了解PP和银离子对开花生理的作用奠定了基础。
