摘要
竹类植物是重要的禾本科经济植物。由于开花周期长且难以预测 ,大多数竹种终身一次开花并导致死亡 ,具有自然结实率低等独特的开花习性 ,使得竹子开花及相关研究受到了很大的限制。通过竹子开化的人工诱导与逆转的研究 ,不仅可以人工获取难得的竹子种子 ,更为竹种分类鉴定、杂交遗传育种和开花机理等多方面研究工作提供了良好的基础 ,其理论意义和应用价值都十分重大。迄今为止 ,印度和比利时等国研究人员已在至少 8个竹种中成功诱导了竹子的试管开花 ,成功诱导开花逆转的研究也有了报道。通过已建立的实验模式系统 ,对影响诱导试管开花及逆转的因子进行了初步的研究 ,并在开花生理和杂交育种等方面进行了研究尝试。可以相信 ,随着研究的扩展与深入 ,必将为整个竹类植物的研究带来巨大的推动作用。表 1参 1
Bamboo is a versatile species with great economic value.But it normally has a long flowering cycle and the cycle is unpreditable,most species flower and produce seeds only once then die in its lifetime,this peculiarity has hampered the study of flowering behavior and many other aspects in bamboo.The study of artificial induction and reversion of bamboo flowering not only provides a possibility to acquire bamboo seeds annually,but also an attempt at the cross breeding,typology,and investigating of flowering mechanism in bamboo.So far,bamboo flowering in tissue culture has been induced successfully in more than eight species based on published reports from India,Belgium,China,Japan etc,and artificial reversion of bamboo flowering been reported.Based on the model systems of the induction and reversion of bamboo flowering,the actor of influencing induction and reversion of bamboo flowering in tissue culture has been studied,the attempt in hybridization,investigating of flowering mechanism are in progress.It is no doubt that the bamboo research will make great progress with the advance in the study of bamboo flowering.
