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。
The effects of four different constant temperature (10, 10, 20, 25 ℃) treatments on the germination of blue thistle seed were studied using the blue thistle seed as the test material. The test materials were used to study the germination status in different years under the normal room temperature. The results showed that under the different constant temperature treatment, the germination indexes of 15 ℃ and other treatments were significantly different, which was the suitable germination and constant temperature condition of the blue thistle seeds. The indoor germination test of the blue thistle seeds for nearly 3 years showed that in May, Under the conditions of 2012 and other years to deal with germination indicators were significantly different, the germination of the seeds for the 2012> 2011> 2010; Description Blue Sesame seed suitable temperature during planting is 15 ℃, should be selected when sowing that year Newborn seeds, in order to obtain a better germination, in order to facilitate the stable harvest.
