摘要:

为探究NaCl胁迫下切花芍药的生理生化特性,以切花芍药品种秀兰·邓波尔开花级数为一级的花枝为试验材料,采用水培的方法,用不同浓度NaCl(0,0.2%,0.4%,0.6%)溶液处理,观测花枝的表型变化,用DAB、NBT染色和测定相应的生理生化反应,了解切花芍药秀兰耐盐潜力,探究切花芍药的耐盐机理。结果表明:切花芍药秀兰在0.2%轻度盐胁迫时枝条表型无明显变化,0.4%盐胁迫叶片开始出现轻微黄化卷曲现象,0.6%盐胁迫下盐害症状更加明显,叶片卷曲皱缩。盐胁迫下芍药叶片含水量,叶绿素含量均随着盐浓度的升高显著下降;电解质渗透率,脯氨酸含量显著上升;高浓度盐胁迫导致芍药叶片活性氧($\mathrm{O}^{\bar{.}}_{2}$和 H2O2)积累显著,多种抗氧化酶活性显著上调。综上所述,0.2%盐胁迫对切花芍药秀兰影响较小,但0.4%及以上的盐浓度超出秀兰的耐受范围;切花芍药秀兰主要通过增加渗透调节物质和提高抗氧化酶的含量来应对盐胁迫。

Abstract:

To explore the physiological and biochemical characteristics of cut peony under NaCl stress,the flower branches of the cut peony variety Shirley Temple with the first level of flowering series as the test material were treated with different concentrations of NaCl(0,0.2%,0.4%,0.6%)by hydroponics method.The phenotype changes of the flower branches were observed,and the corresponding physiological and biochemical reactions were measured by DAB and NBT staining,so as to understand the salt tolerance potential of the cut peony Shirley.To explore the salt tolerance mechanism of cut flower peony.The results showed that there was no significant change in branch phenotype of peony Xiulan under 0.2% salt stress,the leaf became slightly yellowed and curled under 0.4% salt stress,and the leaf curled and wrinkled under 0.6% salt stress.Under salt stress,leaf water content and chlorophyll content decreased significantly with the increase of salt concentration.Electrolyte permeability and proline content were significantly increased.The accumulation of reactive oxygen species($\mathrm{O}^{\bar{.}}_{2}$ and H2O2)and the activity of various antioxidant enzymes were significantly up-regulated under high concentration salt stress.In summary,0.2% salt stress had little effect on Xiulan,but 0.4% and above salt concentration exceeded the tolerance range of Xiulan.The cut peony Xiulan can cope with salt stress mainly by increasing the content of osmoregulatory substances and antioxidant enzymes.
