摘要
通过发芽试验探讨不同温度、pH值和湿度处理对地锦草(Euphorbiae humifusa)种子萌发的影响。结果表明:不同温度、pH值和湿度对地锦草种子的萌发均有显著影响。地锦草种子在30℃左右时发芽率和发芽指数最高,分别为52%和22.6。不同pH值处理时,pH值为7时其发芽率和发芽指数最高,分别为48%和23.79。不同湿度处理时,当湿度为90%时,地锦草种子的发芽率和发芽指数最高,分别为55%和23.02。
The influences of different temperatures,pH and humidities on the germination characteristics of Euphorbia humifusa were studied.The results showed that different temperatures,pH and humidities had significant influences on the germination characteristics of E.humifusa.The germination rate and index of E.humifusa seed performed best under 30 ℃ with 52% and 22.6,respectively;The best pH value was 7,under which the germination rate and germination index were 48% and 23.79,respectively.When the humidity was 90%,the E.humifusa seed germination rate and germination index were 55% and 23.02,respectively.
