能源植物续随子光合特性研究
|
摘要
续随子是一种优良的新型油料作物,其种子含油量很高,开发利用前景广阔。研究主要测定了续随子生长发育过程中6,7,8月的光合作用参数,综合考虑了续随子外部环境因素(光照强度(PAR)、田间CO2浓度(Ca)、环境温度(Ta)、相对湿度(RH))和内部自身因素(蒸腾速率(Tr)、气孔导度(Gs)、胞间CO2浓度(Ci))对其光合作用的影响,并分析了各项指标与净光合速率之间的相关性。结果表明,6,7,8月续随子净光合速率变化呈现单峰曲线,峰值出现在7月20日,最大值为16.87μmol/(m2·s);续随子净光合速率与蒸腾速率、气孔导度、光照强度和环境温度均呈正相关,而与胞间CO2浓度、田间CO2浓度及相对湿度呈负相关。
Euphorbia lathyris L. is an excellent new oil crop, which has high seed oil content and broad prospects for development and utilization. In this paper, the photosynthesis of Euphorbia lathyris growth and development in June, July and August was investigated.The external environmental factors(the light intensity(PAR), field CO2 concentration(Ca), ambient temperature(Ta)and relative humidity(RH))and internal factors(transpiration rate(Tr), stomatal conductance(Gs), intercellular CO2 concentration(Ci))were measured. The correlation between net photosynthetic rates and various photosynthetic indicators were analyzed. The results showed that the change of net photosynthetic rate exhibited a single-peak curve in June, July and August, and the peak occurred on July 20, the maximum value was 16.87 μmol/(m2·s). The net photosynthetic rate was positively correlated with transpiration rate, stomatal conductance, light intensity and ambient temperature, but was negatively correlated with intercellular CO2 concentration, field CO2 concentration and relative humidity.
