摘要:
为探究不同月季品种对盐溶液的生理响应，以两个月季品种“法兰西”和“红宝石”的二年生栽培苗为材料进行盆栽试验，采用0‰、2‰、4‰和6‰浓度梯度的NaCl溶液进行盐胁迫，测定和分析叶片相对含水量、叶绿素含量、叶片水势、相对电导率、丙二醛含量、脯氨酸含量、蒸腾速率、净光合速率、胞间二氧化碳浓度、气孔导度等生理指标。结果表明，“红宝石”的叶片相对含水量随盐浓度的增加先下降再上升再下降，在4‰盐浓度时，叶片相对含水量都有回升的趋势，“红宝石”和“法兰西”在4‰盐浓度时都有较强的保水能力。且两者的叶片叶绿素含量随盐浓度增加逐渐减小，“法兰西”的叶绿素含量各浓度间差异不显著，“红宝石”的叶绿素含量在6‰浓度时和CK差异显著。两者叶片水势先升高后降低，“红宝石”水势变化趋势大于“法兰西”。两者的叶片相对电导率、丙二醛和脯氨酸大体呈上升趋势，气孔导度、蒸腾速率随盐浓度增大而呈降低趋势，净光合速率和胞间二氧化碳浓度随盐浓度增大呈先下降后上升的趋势。
Abstract:
In order to explore the physiological response of different rose varieties to salt solution，the two roses with the same growth Rosa hybrida ‘France La’ and Rosa hybrida ‘Ruby’ were cultured by pot experiment with NaCl solution of 0‰， 2‰， 4‰， 6‰ concentration. After 9 days， the leaves of the same parts were randomly selected for sampling， and physiological indexes including the relative water content， chlorophyll content， leaf water potential， relative conductivity， malondialdehyde content， proline content， transpiration rate， net photosynthetic rate， intercellular carbon dioxide concentration and stomatal conductance were measured. The results showed that the relative water content of Rosa hybrida ‘Ruby’ decreased， then increased， and then decreased again with the increase of salt concentration. When the salt concentration was 4‰， the relative water content of leaves had a rising trend， and both had strong water holding capacity when the salt concentration was 4‰. The chlorophyll content of the two decreased gradually with the increase of salt concentration. There was no significant difference in the chlorophyll content of Rosa hybrida ‘France La’ among different concentrations， there was significant difference in the chlorophyll content of Rosa hybnda‘Ruby’ between CK and the salt concentration 6‰. The leaf water potential of the two plants increased and then decreased， and the change trend of Rosa hybrida ‘Ruby’ water potential was greater than that of Rosa hybrida ‘France La’. The relative conductivity， malondialdehyde and proline of the two increased， while stomatal conductance and transpiration rate decreased with the increase of salt concentration, the net photosyntetic rate and intercellular carbon dioxide concentration decreased first and then increased with the incrcase of salt concentration.
