- 大气CO2浓度升高是全球气候变化的重要特征之一，为揭示未来气候变化对作物种子活力的影响，进行种子发芽对CO2增加的适应性响应研究。2019年在中国科学院海伦农业生态实验站进行开顶式气室（OTC）模拟CO2增加试验，选取东北三大主栽作物大豆、玉米和水稻为供试作物，设置两个CO2处理，分别为aCO2 (400 μmol?mol-1)和eCO2 (700 μmol?mol-1)。结果表明：相比于对照（aCO2）处理，CO2浓度升高后，大豆种子的体积、百粒重、24 h吸胀速度、浸出液电导率、发芽率、发芽势和发芽指数分别降低了11.24%、10.53%、2.51%、27.72%、15.85%、19.75%和10.17%；虽然CO2升高未显著影响玉米种子百粒重，但其24 h吸胀速度和浸出液电导率分别降低了3.69%和8.62%，而发芽率、发芽势、发芽指数和活力指数分别提高了81.03%、75.00%、56.14%和81.68%；水稻种子的体积降低了21.35%，而其千粒重、发芽势、发芽指数和活力指数分别提高了5.62%、5.19%、26.11%和32.21%。综合以上结果表明，大气CO2浓度升高对不同作物种子活力的影响存在差异，从发芽指标来看，大气CO2浓度为700 μmol?mol-1时，种子活力表现为玉米>水稻>大豆。
- Abstract:
- Elevated atmospheric CO2 concentration is one of the important characteristics of global climate change. In order to reveal the impact of future climate change on the vitality of crop seeds, a germination experiment was carried out to study the adaptive response of seeds to elevated CO2. In 2019, an open top chamber (OTC)was set up to simulate CO2 enrichment at Hailun Agroecological Experimental Station, Chinese Academy of Sciences. Three major crop including soybean, maize and rice of Northeast China were selected as test material. Two CO2 treatments were aCO2 (ambient CO2, 400 μmol?mol-1) and eCO2 (elevated CO2, 700 μmol?mol-1). The results showed that eCO2 decreased seed volume, 100-seed weight, 24 h-imbibition speed, electrical conductivity rate of seeds soaking solution, germination rate, germination potential and germination index in soybean seeds decreased by 11.24%, 10.53%, 2.51%, 27.72%, 15.85%, 19.75% and 10.17% compared to aCO2, respectively. Although CO2 enrichment did not significantly influence the 100-seed weight of maize, the 24 h-imbibition speed and electrical conductivity rate of seeds soaking solution in maize seeds at eCO2 decreased by 3.69% and 8.62%, respectively. The germination rate, germination potential, germination index and vigor index of rice seeds at eCO2 increased by 81.03%, 75.00%, 56.14% and 81.68% compared to aCO2, respectively. The volume of rice seeds decreased by 21.35%, while the 1000-seed weight, germination potential, germination index and vigor index increased by 5.62%, 5.19%, 26.11% and 32.21%, respectively. All these indicated that the responses of various crop seeds to elevated atmospheric CO2 were different. Totally, at 700 μmol?mol-1 CO2 concentration, the seed vitality was maize>rice>soybean.
