| 摘 要： | 【目的】研究不同浓度NaCl和NaHCO3溶液对2种制干辣椒品种红椒王和川椒19号光合特性的影响。【方法】以红椒王和川椒19号为试材，以NaCl和NaHCO3溶液浓度为变量，采用盆栽定量浇灌，测定现蕾时辣椒叶片的净光合速率、蒸腾速率、气孔导度和胞间CO2浓度，利用相关性分析、线性回归分析2种制干辣椒品种光合特性日变化规律。【结果】在栽培基质中分别浇灌50、100、150和200 mmol/L NaCl和NaHCO3溶液后，辣椒叶片受到了NaCl和NaHCO3胁迫而出现了净光合速率、蒸腾速率、气孔导度和胞间CO2浓度降低的变化现象。在200 mmol/L NaCl处理下红椒王日平均净光合速率最低为13.79μmol/(m2?s),川椒19号在200 mmol/L NaHCO3处理下日平均净光合速率最低为16.85μmol/(m2?s)。【结论】NaCl和NaHCO3胁迫对...

| Abstract: | 【Objective】 To study the effects of different concentrations of NaCl and NaHCO3 on the photosynthetic characteristics of two dried pepper varieties Hongjiaowang and Chuanjiao 19. 【Methods】 Hongjiaowang and Chuanjiao 19 were used as test materials, NaCl and NaHCO3 solution concentrations as variables, the net photosynthetic rate, transpiration rate, stomatal conductance and intercellular CO2 concentration of pepper leaves at flowering stage were measured by pot irrigation.Correlation analysis and linear regression analysis were used to explore the diurnal variation of photosynthetic characteristics of two dried pepper varieties. 【Results】 Under NaCl and NaHCO3 stress, the net photosynthetic rate, transpiration rate, stomatal conductance and intercellular CO2 concentration of pepper leaves were decreased after 50, 100, 150 and 200 mmol/L NaCl and NaHCO3 were irrigated in the culture substrate, respectively.Under 200 mmol/L Nacl treatment, the lowest daily average net photosynthetic rate of Hongjiaowang was 13.79 μmol/(m2·s), and that of Chuanjiao 19 was 16.85 μmol/(m2·s) under 200 mmol/L NaHCO3 treatment. 【Conclusion】 NaCl and NaHCO3 stress inhibit the photosynthetic characteristics of two dried pepper varieties Hongjiaowang and Chuanjiao 19. |
