需水阈值
相关语句
  critical water potential
     The experiments demonstrated that.drought-resistant ability of seedling with water uptake proceeding, the relationship between the time (t)of radicle emergence, plumule emergence or seedling establishment and external water potential (w) could be regressed with formula 1/t =a+b w. The critical water potential derived from the formula varied at differ-ent stages.
     种子达到萌动,萌发及出土成苗所需时间(t)与外界环境水势(W)之间1/t=a+bw的关系,据此推算出玉米种子在不同成苗阶段的需水阈值,发现种子在不同成苗过程中对环境水分的反应不同,抗旱性也不同。
