温度和年份对蓝蓟种子发芽状况的影响

Effect of Temperature and Ages on Seeds Germination of Echium vulgare

以蓝蓟种子为试材,研究人工气候箱培养条件下,4种不同恒定温度(即10、15、20、25℃),处理对蓝蓟种子发芽状况的影响;并以近3a篮蓟种子为试材,比较研究了常规室温条件下不同年份的发芽状况。结果表明:不同恒定温度处理条件下,15℃与其它处理的发芽指标具显著差异性,为蓝蓟种子适宜的发芽恒温条件;近3a的蓝蓟种子进行室内发芽试验结果表明,在5月份室内条件下,2012年与其它年份处理发芽指标具显著差异性,种子的发芽状况为2012年>2011年>2010年;说明蓝蓟种子播种时期适宜的恒温条件为15℃,在播种时应选择当年新生种子,以获得较好的发芽状况,以利于稳定收获。

Taking seeds of Echium vulgare as material, the effect of four different constant culture temperatures （10,15, 20,25℃） under artificial constant on seed germination of Echium vulgate were studied;and with nearly three-year seeds as material,the germination condition under normal temperature were compared. The results showed that, 15℃ was the suitable temperate conditions for Echium vulgate seed germination, there were significant differences of germination between 15℃ and others. Meanwhile,through trailing Echiurn vulgate seeds of nearly three-year for room germination test. In the room conditions in May, 2012, the Echiurn vulgare seed germination was better and there were significant differences between 2012 and the other years treatment germination index;Echium vulgate seeds of nearly three-year seed germination was 2012〉2011 〉 2010. This illustrated that 15℃ was the appropriate temperature conditions of Echium vulgate seed sowing time, and should choose the freshest seeds for sowing, in order to obtain better germination conditions and the steady gains at the end of the entire period.
