温度胁迫对罂粟种子萌发影响及其活力变化规律的研究
Effects of temperature stress on germination and vitality of Papave somniferum seeds
摘要
Abstract
The effects of temperature stress on the germination and vitality of seeds of Papave somniferum L. were studied to preserve poppy germplasm resources and prevent seed aging. The results showed that poppy was high tem-perature sensitive and was able to germinate under low temperature. The favorable temperature for their germination was 10-20℃ ,and the optimal temperature was 18℃ ,the temperature lower than 5℃ and higher than 20℃ all could affect its germination. The temperature should be controlled within 60℃ and the heating time under 60 mi-nutes when seeds pelleting. Under normal inventory conditions, with storage time increased, the poppy seed vigor dropped,and germination rate declined less than 50% as the storage time over 5 years,and was not suitable for breed-ing, so as the germplasm resources,it must breed again every 5 years.关键词
