- 开的种子在受控的盐水条件下发芽和生长.
- 评估的关键参数包括发芽率,根长度,内源硫化 (H2S) 含量,抗氧化能力,氧化应激标志物 (H2O2,TBARS) 和膜完整性.
主要成果:
- 度降低了发芽率到30%和根长度到1.6毫米的未加工的种子.
- 无论是0.1毫米和10毫米的NaHS原料处理,与水性原料处理相比,都显著改善了发芽和根长度.

01:57Adaptations that Reduce Water Loss
28.3K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
