First , I have an experiment with 24 pots where 10 quinoa seeds were swoon in each pot , unfortunately in the pots that were irrigated 10ds/m-1 and 15ds/m-1 their were low germination and in 15ds/m-1 nothing germinated . I was wondering what are the factors that might have affected my experiment , soil salinity wasn't above what quinoa can tolerate , soil PH is also at the level quinoa can tolerate
I repeated the experiment , in the same pots that were irrigated with saline water , first I added fresh water for 7 days and then 7 days with saline water , 2 pots out of 6 germinated in 10ds/m-1 even with fresh water irrigation first , nothing germinated in 15 NaCl , I thought if it was the salinity all pots won't germinate but they have almost the same level of soil salinity , irrigated with 200 mL each , so I don't know why the won't germinate or why only 2 pots out of 6 germinated ? what other factors that can affect quinoa seed germination ?
I would poke around in the literature a bit. Temperature requirements may be key. I've read that quinoa prefers cooler conditions and that quinoa seeds may not germinate if conditions are warm and may need to be refrigerated for a week (vernalized) to obtain adequate germination. https://www.hort.purdue.edu/newcrop/afcm/quinoa.html
i had some experiment in salinity condition, probably in some pot, because of evaporation, the salinity deeply increased especially in light pot. also, in country we saw seed in the autumn( cold condition).
