温度和光照对藜麦幼苗生长发育的影响

以藜麦为材料，采用水培方法，设置2种光照时间（8和12 h）和2种温度（10和25 ℃）对藜麦幼苗进行交叉处理。研究不同温度和光照对藜麦幼苗的发芽率、鲜质量、干质量、含水量、株高和根长、根系活力和叶绿素含量的影响，为藜麦的高产种植提供依据。结果表明:25 ℃下光照8 h时，幼苗整株鲜质量、干质量和株高最大，但与其他处理差异不显著；10 ℃下光照12 h时，幼苗叶绿素含量和根系活力最高。可见，低温延长光照时间有利于藜麦后期生长，并且藜麦适于高寒地区种植。 

Effects of Temperature and Light on Growth and Development of Quinoa Seedlings

Quinoa seedlings were cross-treated with two different light periods（8 and 12 hours）and two different temperatures（10 and 25 ℃）.Effects of temperature and light on germination rate，fresh weight，dry weight，water content，plant height and root length，root activity and chlorophyll content of quinoa seedlings were studied in order to provide basis for high yield planting.Results showed that fresh weight，dry weight and plant height of seedlings were the highest at 25 ℃ for 8 h，but there was no significant difference with other treatments.Chlorophyll content and root activity were highest when seedlings were exposed to 12 h light at 10 ℃.It could be seen that low temperature prolonging illumination time was conducive to later growth of quinoa，and quinoa was suitable for planting in cold areas.
