Life-history strategy is the significant research area of plant population ecology.
生命史对策是植物种群生态学的重大研究领域.
Seed germination is the critical stage of plant life history.
种子萌芽是植物生命史的重要阶段.
Therefore,research on seed germination rule and strategy helps to know and elucidate plant evolution and ecological adaptation traits.
因此,研究种子萌芽规律和对策有助于我们了解和解释植物进化和生态适应特征.
Plants in Songnen grassland area were used to test the responses of seed germination to constant temperature and diurnal increased or decreased temperature,the effects of global warming simulated by alternating temperature regimes on seed germination of C3 and C4 species,plant germination pattern and the changes under different constant temperature.
松嫩草原地区的植物被用于测试种子萌芽对恒温和白天上升或下降气温的反应、通过改变温度状况模拟的全球气候变暖对C3和C4物种种子萌芽、植物萌芽模式所带来的影响和在不同恒温下的变化.
The mechanisms of germination responses to NaCl and PEG and the interaction between salt and temperature were also studied.
还研究了种子萌芽对NaCl和PEG的反应机制以及盐和温度之间的相互作用.
Photosynthetic contribution of cotyledons to seedling growth was evaluated as well.
同时也评估了子叶的光合作用对幼苗生长的影响.
According to the results of constant temperature effects,we proposed the modified thermal time model on the basis of thermal time model and supplemented an equation describing germination rate constant.
根据恒温效应的结果,我们在热时间模型的基础上提议这个改良的热时间模型,并补充了一个反映萌芽率参数的等式.
Germination rate of C3 species was lower than C4 species.
C3 物种的萌芽率比C4 物种的要低.
According to thermal time model,the average base temperature of C3 species was lower than C4 species,but not significantly.
根据热时间模型,C3 物种的平均基准温度比C4 物种的要低,但是差别不是很明显.
The average thermal time constant of C3 species was higher than C4 species,which approached significant difference.
C3 物种的平均热时间常数比C4 物种的更高,差别非常明显.
In this study,plant seed germination pattern was divided into five categories:quick germination,delayed germination,steady germination,normal germination and delayed-quick germination.
再此研究中,植物种子萌芽模式分为 5 类:快速萌芽、延期萌芽、稳定萌芽、正常萌芽和延期-快速萌芽.
Most annual species belonged to quick germination pattern.
大部分的一年生植物属于快速萌芽模式.
Perennial C3 species,which distributed to meadow,belonged to delayed-quick germination pattern,normal germination pattern or steady germination pattern.
分布在草地区域的多年生植物C3物种属于延期-快速萌芽模式、正常萌芽模式或稳定萌芽模式.
Seed germination pattern of most species changed with temperature,which was an adaptive strategy to environments.
大多数物种的种子萌芽模式根据温度来变化,这就是对环境的适应策略.
Under global warming simulated by alternating temperature regimes conditions,germination traits of C3 and C4 species changed.
通过改变温度状况来模拟全球气候变暖,C3 和C4物种的萌芽特征都发生变化.

附录:
Plants in Songnen grassland area were used to test the responses of seed germination to constant temperature and diurnal increased or decreased temperature,the effects of global warming simulated by alternating temperature regimes on seed germination of C3 and C4 species,plant germination pattern and the changes under different constant temperature.
松嫩草原地区的植物被用于测试种子萌芽对恒温和白天上升或下降气温的反应、全球气候变暖(通过改变温度状况进行模拟)对C3和C4物种种子萌芽、植物萌芽模式所带来的影响和在不同恒温下的变化.
这句话这样可能会比较好理解.
