摘要利用非食用植物生产纤维素生物乙醇是应对全球气候变暖的一个潜在对策。蔗茅属物种提供生物乙醇的纤维素原料，因为它们具有高生物量生产力和对环境胁迫的高耐受性，与它们的大而深的根系相关。然而，由于根广泛分布在土壤中，因此很难通过直接观察根系来选择蔗茅属物种进行育种。相反，我们研究了可能与根形态密切相关的芽形态性状，以找到有效的选择参考指标。根据伤流率评价蔗茅属植物根系结构和功能的潜力也进行了研究。幼苗根冠关系分析表明，根数和平均长度分别与茎数和直径密切相关。这些结果表明，根冠关系可能为蔗茅根系的选择育种提供有用的标准。
Abstract The production of cellulosic bioethanol from non-edible plants is a potential countermeasure against global warming. Erianthus species provide cellulosic raw material for bioethanol because they have high biomass productivity and high tolerance to environmental stress, associated with their large, deep root systems. However, it is difficult to select Erianthus species for breeding by direct observation of their root systems because the roots are widely dispersed in the soil. Instead, we examined shoot morphological traits that could be closely related to root morphology to find effective reference indices for selection. The potential to evaluate root structure and function in Erianthus according to bleeding rate was also examined. An analysis of root–shoot relationships in seedlings indicated that root number and mean length were closely related to stem number and diameter, respectively. These results suggest that root–shoot relationships may provide useful criteria for selective breeding of root systems in Erianthus.
