Liquid-holding recovery (LHR) and the sparing effect of dose fractionation were investigated with 100 kVp-X-rays in diploid yeast from exponential and stationary phase. Exponential cells showed prompt and complete split-dose recovery. The ability to undergo LHR remained constant during 2-5 hours incubation after the first dose. Stationary-phase cells did not exhibit split-dose recovery (SDR) in a simple way: there was an increase in sensitivity after 3-5 hours followed by a gradual increases with time. It is suggested that stationary cells are starved of an essential co-factor which has to be synthesized de nova.
用100 kVp的X射线对处于指数生长期和稳定期的二倍体酵母进行了液体保持恢复（LHR）和剂量分割的 sparing 效应研究。指数生长期的细胞表现出迅速且完全的分次剂量恢复。在第一次照射后2至5小时的孵育期间，进行LHR的能力保持恒定。稳定期的细胞没有以简单的方式表现出分次剂量恢复（SDR）：在3至5小时后敏感性增加，随后随时间逐渐增加。有人认为，稳定期细胞缺乏一种必需的辅助因子，这种因子必须重新合成。
