Effect of NaHCO3 and Na2CO3 Stress on Seed Germination of Chenopodium album L.
The research used two different sodium salt with different concentrations acting on Chenopodium album L. and though sprout experiment to study the influence of two sodium salt stress to Chenopodium album L. seeds sprouting as well as to analyse its salt tolerance. The results showed that with the increase of the concentration of two salt, germination rate, germination potential, germination index and vigor index had a significant decrease and an overtopped salt concentration （NaHCO3 at 250 mmol/L, Na2CO3 at 200 mmol/L） could inhibit the seeds sprout completely. The inhibition effect of two sodium salt to radicle and germ of sprouted Chenopodium album L. was different. The inhibition effect of NaHCO3 was root 〉 bud, the inhibition effect of Na2CO3 was root 〈 bud.
