摘要:为研究四种不同菊花(勋章菊、雏菊、翠菊、白晶菊)品种种子在不同催芽方式下的发芽率的对照研究,设置了3组种子萌发实验对照:
① 热水浸泡处理(温度25℃,50℃,80℃),浸泡时间均为2h。
② 光暗处理,一组在播种前放在光照处24h,一组则放在黑暗处24h。
③ 赤霉素(浓度0.02﹪、0.04﹪、0.06﹪)浸泡处理20分钟。20023
播种15天后,测这四种种子的发芽势、发芽率、发芽指数、活力指数并进行对比。结果表明,不同品种的菊花种子在相同催芽处理方法下,发芽率不相同,且在温度相同情况下,发芽率亦不同。

Four seed germination of different varieties of chrysanthemum control technology research
Abstract: in order to study the four different varieties of chrysanthemum seeds (Gazania rigens,Bellis perennis,Callistephus chinensis,Chrysanthemum paludosum)in a controlled study of germination under different pregermination ways, 3 sets of seed germination experiment:
① The hot water treatment (25 ℃, 50 ℃, 80 ℃), immersion time of 2h.
② The light and dark treatment, a group of seeds on the light at the 24h, a group in a dark room 24h.
③ The gibberellin (concentration 0.02%, 0.04%, 0.06%) soaked for 20 minutes.
After 15 days,comparison of post test this four seed germination potential, germination rate, germination index, vigor index and. The results show that, different varieties of chrysanthemum seeds in the same methods of treatment, the germination rate is not the same, and the situation in the same temperature, also different germination rate.
