以藜麦品种“陇藜一号”和“陇藜三号”为试验材料，探索NaCl胁迫对藜麦

Using quinoa varieties "Long Qi No. 1" and "Long Qi No. 3" as experimental materials, explore the effects of NaCl stress on quinoa seed germination and seedling growth. Six NaCl solutions with different concentration gradients were set to treat the seeds and seedlings of two kinds of quinoa, and their germination rate, plant dry weight, soluble sugar, proline, flavonoids, chlorophyll, malondialdehyde content, etc. Determine and explore the effects of salt stress on the germination and physiological indexes of quinoa. The results showed that (1) when the salt concentration reached the maximum (300 mmol / L), the germination rate of "Long Qi No. 1" and "Long Qi No. 3" did not change significantly compared with the blank control; (2) salt stress The plant height of the lower seedlings was significantly inhibited, and the growth and biomass accumulation of the aerial parts and roots were inhibited, but the roots were inhibited to a lesser degree; The content of flavonoids and flavonoids increased first and then decreased with the increase of salt concentration, while the content of malondialdehyde, proline and soluble sugar gradually increased. In summary, the appropriate concentration of salt treatment (50 ~ 300 mmol / LNaCl) can promote the germination and seedling growth of quinoa seeds.

The effects of NaClco on the germination of quinoa seeds and their seedlings are explored with the quinoa varieties "Quinoa One" and "Quinoa III" as test materials. The NaCl solution with 6 different concentration gradients was arranged to process the seeds and seedlings of two quinoa, and to determine the germination rate, plant dry fresh weight, soluble sugar, proline, flavonoids, chlorophyll, acetal content, etc., to investigate the effects of salt stress on the germination and physiological indicators of quinoa. The results showed that when the salt concentration reached the maximum (300mmol/L), the germination rate of "Quinoa 1" and "Quinoa 3" was not significantly different from the blank control; Both were inhibited, but the degree of inhibition in the root was lower, (3) the chlorophyll content of "Quinoa One" and "Quinoa 3" seedlingchlorophyll ingivation and flavonoid content decreased with the increase of salt concentration, while the content of acetyl, proline and soluble sugars increased gradually. In summary, the suitable concentration of salt treatment (50 to 300 mmol/LNaCl) can promote the germination and seedling growth of quinoa seeds.

The effects of NaCl stress on Seed Germination and seedling growth of quinoa were studied by using quinoa varieties "Longjian No.1" and "Longjian No.3". Six NaCl solutions with different concentration gradients were used to treat the seeds and seedlings of two kinds of quinoa, and the germination rate, dry and fresh weight, soluble sugar, proline, flavonoids, chlorophyll, malondialdehyde content were measured to explore the effect of salt stress on the germination index and physiological index of quinoa. The results show that, (1) When the salt concentration reached the maximum (300mmol / L), the germination rate of "longquino No.1" and "longquino No.3" had no significant difference compared with the blank control; (2) the height of seedlings was significantly inhibited under salt stress, the growth and biomass accumulation of shoots and roots were inhibited, but the inhibition degree of roots was relatively low; (3) "longquino No.1" and "longquino No.3" With the increase of salt concentration, the content of chlorophyll and flavonoids increased first and then decreased, while the content of malondialdehyde, proline and soluble sugar increased gradually. In conclusion, salt treatment (50-300 mmol / lnacl) with appropriate concentration can promote the germination and seedling growth of quinoa seeds.
