无需种子，在离地数米的枝头生根发芽 高压繁殖法助博罗红豆“延续血脉”

Core Viewpoint - The research team from the South China Botanical Garden is conducting various propagation experiments to save the endangered species, the Boro Red Bean, which has been facing severe survival challenges due to habitat limitations and lack of healthy seeds [11][15][16]. Group 1: Research and Conservation Efforts - The team has initiated high-pressure propagation experiments to cultivate Boro Red Bean branches, which can root and grow without seeds, addressing the species' critical survival situation [11][16]. - The Boro Red Bean is classified as a national second-level protected plant, with fewer than 1,000 individuals remaining and no healthy seeds produced in the last five years [11][15]. - Various propagation methods, including seed germination, cuttings, and grafting, have shown limited success, prompting the team to focus on high-pressure propagation techniques [16][17]. Group 2: Discoveries and Challenges - The discovery of Boro Red Bean's distribution extending beyond its previously known habitat at Xiangtou Mountain to the Nankun Mountain area has raised hopes for its conservation [12][15]. - Despite initial excitement over the discovery, subsequent searches yielded no new seedlings, highlighting the ongoing survival crisis for the species [15][19]. - The team has faced environmental challenges, including severe drought conditions, which have complicated their conservation efforts [17][19]. Group 3: Public Awareness and Policy Support - There has been a growing public awareness and involvement in ecological protection, with citizens actively reporting destructive behaviors [19]. - The Guangdong provincial government has emphasized biodiversity protection in its ecological construction initiatives, providing a supportive framework for conservation efforts [18][19]. - Increased consultations from forestry departments and frequent invitations for educational talks indicate a rising interest in biodiversity conservation [19]. Group 4: Innovative Approaches - The establishment of a research center in Deqing Forest Farm aims to create a micro-ecological chain by interplanting Boro Red Bean with companion plants, enhancing biodiversity [20][21]. - The center's design considers both conservation and economic benefits, allowing for sustainable harvesting of timber while ensuring the protection of plant species [22][23]. - The long-term vision includes creating a landscape where previously endangered species thrive, contributing to both ecological and economic sustainability [22][23].
