涝渍胁迫对辣椒植株表型的影响
|
摘要
采用高于穴盘的中转箱作为容器模拟涝渍胁迫环境的方法,研究涝渍胁迫对4种类型20个辣椒品种的形态特征、生物量积累等表型可塑性及壮苗指标的影响。结果表明:涝渍胁迫严重抑制了辣椒根系和植株的纵向伸长生长,但是短期涝渍胁迫会促进同化产物向根系的相对积累。本研究通过对各个单项指标与耐涝性关系进行分析,结合观察结果,认为根系耐涝系数和壮苗指标耐涝系数可作为辣椒品种耐涝性的量化评价指标,但是辣椒的耐涝性是一个复杂的综合性状,用任何一个单项指标来评价都有片面性,需要结合各个性状指标进行综合评价。
The effect of waterlogging stress on the phenotypic plasticity and healthy index of 20 Capsicum cultivars grouped into 4 types was studied using the transit box above the tray as a model to simulate waterlogging stress. The results showed that waterlogging stress seriously inhibited the longitudinal elongation of pepper roots and plants, but the short-term waterlogging stress would promote the relative distribution of the assimilate products to the roots. By analyzing the relationship between each individual index and waterlogging tolerance, combined with the observation, we think that the waterlogging resistance coefficient(WTC) of root and healthy index can be used as the quantitative evaluation index of waterlogging tolerance of Capsicum varieties. However, waterlogging tolerance of pepper is a complex and comprehensive trait, which should be comprehensively evaluated according to each trait index. It is unilateral to evaluate with any one single index.
