低温胁迫对不同萌发状态的裸燕麦种子某些生理特性的影响

Effects of Low Temperature on Some Physiological Charactetistics of Wheat Seeds in Different Sprouting Status

对裸燕麦不同萌发状态下的种子进行了0℃、5℃、10℃的低温胁迫。结果表明:随温度的降低,丙二醛含量急剧增加,而脯氨酸和可溶性蛋白含量也表现出明显增加的趋势。在适宜温度下,各处理种子又恢复了生活力,这些保护性物质的增多提高了裸燕麦的抗寒性。

Seeds of naked oat（Avena nuda L.） were treated under 0℃,5℃,and 10℃ in Different Sprouting status.The results showed that with the temperature dropped,the content of MDA,proline and soluble protein increased.Under favorable temperature,the seeds returned to viable.These increasing protective substances improved cold resistance of naked oats.
