摘要:
为提高菊苣种子发芽率和确定适宜播期，研究了温度和光照对菊苣种子萌发的影响。种子发芽试验的温度分别为15、20、25、30、35℃；光照条件分别为光照、暗期中断和黑暗3种条件。结果表明：在25、30℃条件下,种子发芽时间短,发芽率、发芽指数高，说明菊苣种子萌发最适温度为25～30℃；温度过高和过低均可导致发芽期延长，使发芽率和发芽势降低。暗处理不会抑制菊苣种子萌发，但光照对其发芽有促进作用。
Abstract:
In order to improve seed germination rate and identify suitable sowing date,the effects of temperatures and light on germination of Cichorium intybus L.seeds were studied.The test temperature was 15、20、25、30、35℃,respectively,the light condition was light treatment,dark break treatment and dark treatment.The results showed that under the condition of 25 and 30℃,the germination time was short,germination rate and germination index was high,it indicated that the optimal temperature for germination of Cichorium intybus L.was 25～30℃;The germination time was prolonged,the germination percentage,germination potential were decreased under too low and too high temperature conditions.The dark treatment could not resist Cichorium intybus L.seed germination,however,light treatment could promote germination percentage and germination potential of Cichorium intybus L.seeds.
