NaHCO3胁迫下白桦四倍体表型及生理分析
Morphology and Physiology of Autotetraploid Betula platyphylla Responding to NaHCO3 Stress
摘要
Abstract
To evaluate the impact of intraspecies genome duplication on NaHCO3 stress, a series of Betula platyphylla autotetraploids and diploids were generated from the same family. The morphology and physiology of these autotetraploid individuals were compared with those diploid trees. Autotetraploids were superior in injury index and relative growth of height and base diameter compared to diploids. Physiological data revealed autotetraploids were generally higher expression in net photosynthetic rate,soluble sugar content,soluble protein content,proline content,superoxide dismutase activity and peroxidase activity.关键词
