Influence of temperature and soil moisture on seed germination of Cyclobalanopsis glauca

In order to explore the influence of temperature and soil moisture on seed germination of Cyclobalanopsis glauca,the direct seeding,controlling the temperature and soil moisture content in the growth cabinet were used.The results were as follows:seeds germination rates of C.glauca were very low with(12±12.29)% at the temperature 10℃/15℃in the 12-hour lighting,and their maximal germination rates was(81±13.7)% at the temperature of 30℃/35℃.Seeds germination rates were(79±15.9)% under soil moisture content about 30%-40%,and(56.67±19.36)% at soil moisture content about 90%-100%.There were rapid germination and delayed germination countermeasures of seed germination for wild C.glauca.It was shown that temperature affected the seedling height,blade length and blade width of C.glauca seedlings significantly.On the contrary,effects on the ground diameter and leaf number of seedlings were insignificant.The different gradient of soil moisture content also affected the seedling height,ground diameter,blade length and blade width insignificant at a constant temperature.
