Reclaimed water can irrigate farmland, but anions in water can cause salt stress to the plants. In order to study the effects of salt stress on seed germination characteristics, radicle and germ growth of Chenopodium quinoa, this experiment was designed to measure germination rate, germination vigor, radical and germ elongation inhibition rate in six types of quinoa cultivars (Red quinoa, China-red quinoa, Tai-red quinoa, Tai purple-red quinoa, Yellow quinoa, and Tai yellow-red quinoa) under three types of salt treatments ( NaCl, Na2SO4, NallCO3, and control). The salt tolerance of different quinoa varieties was comprehensively evaluated by using the mean square error decision method, and the varieties with strong salt tolerance under different salt stresses were preliminarily selected. The results were as follows: (1) Na2SO4 had the most obvious inhibition effect on germination index of seeds, and the germination rales of six quinoa varieties were relatively low, which kept below 5%, and growth rales in which values were all 0 in four of the cultivars except for Yellow and Tai yellow-red quinoa. The inhibition rates of Na2SO4 on radicle and germ of the other five quinoa varieties were 100% except for Yellow quinoa, the growth rales of China-red quinoa and Tai yellow-red quinoa under NaCl treatment were higher than that of the control, al 9h hand 21 h, the radicle inhibition rates were - 28.32% and -37.57%. (2) The results of the mean aquare error decision method showed that China-red quinoa had higher resistance to NaCl and NallCO3, and Yellow quinoa had higher resistance Lo Na2SO4. All The above results indicate that salt stress is not conducive to the seed germination and growth of quinoa, but planting suitable varieties in different salt areas can improve the survival rale and growth quality of quinoa, so as to reach the requirements of landscaping using reclaimed water as irrigation.
