摘要

自1750年以来,地球大气中的二氧化碳浓度增加了35%以上,目前每年增加约百万分之二(ppm)。由于人类活动的贡献,预计二氧化碳在可预测的未来将继续上升,如果化石燃料仍在燃烧,二氧化碳将在本世纪的某个时候翻一番。因此,预计到2100年,气温将从2°C上升到5°C。随着二氧化碳的增加,一些生态系统将在未来几十年面临挑战,因为植物将生活在更温暖的温度、更高的蒸发需求以及干旱时间和严重程度的广泛变化中。为了在不断变化的气候环境中生产出健康的作物和森林,至关重要的是要确定二氧化碳浓度升高是否会干扰种子发芽和植物形成,更重要的是,是否会干扰赋予耐旱性的生理特征。在这里,我们回顾了目前对二氧化碳在植物生长和种子发芽中所起作用的理解,以及它在干旱和盐度等非生物胁迫下的影响。

Plant and seed germination responses to global change, with a focus on CO2: A review
Earth atmospheric CO2 concentration has risen by over 35% since 1750 and is presently increasing by about 2 parts per million (ppm) every year. Due to contributions from human activity, CO2 is projected to keep rising in the predictable future and to double sometime during this century if fossil fuels burning remains. As a result, air temperature is projected to rise from 2 to 5 °C by 2100. Following this rise in CO2, some ecosystems will face challenges in the next few decades as plants will live in warmer temperatures, higher evaporating demand and widespread changes in drought lengths and severity. To yield healthy crops and forests in changing climate surroundings, it is vital to define whether elevated CO2 disturbs seed germination and plant formation, but even more, the physiological traits conferring drought tolerance. Here, we review the current understanding on the role that CO2 plays on plant growth and seed germination, as well as its impact during the exposure of abiotic stresses like drought and salinity.
