查询词典 Ac

The results showed that the frequency of germination were able to be increased by keeping seed vessel, culturing seeds with radicle up and pre-treating seeds in 5.0mg/L GA3 solution for 12h. The frequency of explant-browning was reduced by adding AC 0.5mg/L to induction media and the vigor of plantlets was promoted by the AC-adding. The propagating coefficient could be improved and the frequency of bud-vitrifration increased by adding 150mg/L coconut water.
