How different water, temperature and CO2 levels affect soybean height, yield and seed quality conducted in convirons, field trials and glasshouses

Soybeans were planted in the open field with water availability at 45%, 65% and 90%. Heights were collected every two weeks. Yield was determined at harvest where after the seed quality tests were preformed. Plant dry mass was also measured. The seed quality testing consisted of standard germination, accelerated ageing and electrical conductivity tests. Temperature trials (22, 28 and 35 degrees Celcius) were conducted in glasshouses and convirons where the yield was determined at harvest as well as the dry plant and root mass. Thereafter, seed quality testing was performed. Elevated CO2 trials were also conducted in convirons were the CO2 levels where 412ppm and 700ppm. Heights were collected every 2 weeks. Yield was determined at harvest where after the seed quality tests were performed. Within each main test i.e. water, CO2 and temperature experiment, the effect of inoculation with Bradyrhizobium was also measured against organic N fertiliser in the form of LAN (28%)

大豆在露天田野中种植，水分供应分别为45%、65%和90%。每隔两周收集植株高度数据。收获时测定产量，随后进行种子质量测试。同时，植株干燥质量也被测量。种子质量测试包括标准发芽率测试、加速老化测试和电导率测试。温度试验（22°C、28°C和35°C）在温室和可控环境中进行，收获时测定产量以及干燥植株和根的质量。随后，进行种子质量测试。在温室中进行的增温CO2试验中，CO2浓度分别为412ppm和700ppm。每隔两周收集植株高度数据。收获时测定产量，随后进行种子质量测试。在每个主要试验中，例如水分、CO2和温度实验，还测量了接种根瘤菌与有机氮肥（LAN，含氮28%）对产量的影响。
