蓖麻二倍体与同源四倍体光合特性和逆境生理指标的比较研究
Comparative Studies on Photosynthetic Characteristics and Stress Physiological Indexes Between Diploid and Autotetraploid in Ricinus communis L.
摘要
Abstract
[Objectives] In order to evaluate the breeding significance of autotetraploid castor.[Method] comparative studies were carried out on photosynthetic characteristics and stress physiological indexes between diploid and autotetraploid in castor in this paper.[Result] The chlorophyll content,the net photosynthetic rate,the soluble sugar content,the soluble protein content,the free proline content,the peroxidase (POD) and superoxide dismutase (SOD) activity in leaves of the autotetraploid were significantly higher than those in diploid,increased by 30％,53.47％,19.23％,25.22％,11.72％,262.07％ and 24.20％ respectively.Meanwhile the malondiadehyde (MDA)accumulation in autotetraploid was significantly reduced by 30.57％.[Conclusion] Tetraploid castor provides valuable new germplasm for germplasm resources of castor.关键词
