To explore the effects of environmental factors on seed germination and seedling growth of Phalaris paradoxa L.and Phalaris minor Retz.,we conducted some experiments of temperature,pH,salt stress,soil water content,and burial depth in comparison to wheat in laboratory.The results showed that:(1)Seed germination of P.paradoxa L.and P.minor Retz.was obviously different to wheat,and significantly affected by temperature,salt stress and burial depth.The germination rates of wheat under conditions of temperature 5℃,NaCl concentration 0.25 mol/L and burial depth 30 mm were 89.33%,53.33% and 95.00%,respectively;however,seedlings of P.paradoxa L.and P.minor Retz.were not emerged at the same conditions.(2)The seeds of P.paradoxa L.and P.minor Retz.had some resistance to pH stress and drought stress.Over 60% seeds of P.paradoxa L.and P.minor Retz.were germinated within pH 5.0~10.0 and soil water content 12.5% exceeded,but their germination rates were significantly inhibited when pH was 4.0 and soil water content was 10%.As soil water content was 10%,germination rates of P.paradoxa L.,P.minor Retz.and wheat were 19.33%,16.67% and 0%,respectively.(3)The seedling growth of P.paradoxa L.and P.minor Retz.was markedly influenced by environmental factors,in which temperature 25℃~30℃,pH 6.0~9.0,NaCl concentration under 0.05 mol/L,and burial depth less 5 mm were the optimum environmental factors.Environmental factors play one of the most important roles in seed germination and seedling growth of P.paradoxa L.and P.minor Retz.,and the temperature,salt stress and burial depth are identified as the key environmental factors.
