- 以日光温室不同辣椒品系12个品种为试材，研究了低温弱光对辣椒生长发育及光合特性的影响，旨在为辣椒设施栽培和研究耐低温弱光逆境鉴定方法提供参考依据。结果表明：“陇椒3号”辣椒茎粗最小，“京彩”辣椒茎粗最粗为13.78 mm，“63号”和“60号”辣椒始花节位最低为7.2节，“京彩”辣椒始花节位最高为8.8节，“70号”辣椒株高最低为55.8 cm，“74号”辣椒的株高最高为115.6 cm，“63号”辣椒株幅最小为38.4 cm，“京彩”辣椒株幅最大为60.4 cm，“48号”的总叶绿素含量最高为62.23 mg/g，“121-7号”的总叶绿素含量最低为47.04 mg/g。“70号”、〖JP2〗“55号”辣椒叶片胞间CO2浓度下降幅度最高，分别为514、513 μmol/mol，“陇椒3号”辣椒叶片胞间CO2浓度下降幅度最低为391 μmol/mol，“70号”辣椒叶片净光合速率下降幅度最高为8.66 μmol?m-2?s-1，“63号”、“60号”、“48号”辣椒叶片净光合速率下降幅度最低，波动于0.34～0.70 μmol?m-2?s-1，“67号”辣椒叶片气孔导度下降幅度最高为4 130.5 mol?m-2?s-1，”74号”、“60号”、“70号”辣椒叶片气孔导度下降幅度最低，波动于51.4～498.0 mol?m-2?s-1，“74号”、”67号”辣椒叶片的蒸腾速率下降幅度最高，分别为5.54、5.16 mmol?m-2?s-1，”60号”、”62号-6”、“63号”辣椒叶片蒸腾速率下降幅度最低，分别为2.06、2.20、2.24 mmol?m-2?s-1。
- Abstract:
- 12 different pepper lines were used as materials，effect of low temperature and weak light on growth and photosynthetic characters in pepper strain were studied，to provide reference for greenhouse cultivation and method for resistance to weak light stress at low temperature.The results showed that，‘Longjiao 3’ pepper had minimum stem diameter，the stem diameter of the ‘Jingcai’ was the maximum with 13.78 mm,the start flower festival of of ‘63’ and ‘60’ pepper were lowest for the 7.2 section，the start flower festival of the ‘Jingcai’ pepper was the highest for the 8.8 section,the plant height of‘70’ pepper was the lowest of 55.8 cm，the plant height of ‘74’ pepper was the highest of 115.6 cm，strain amplitude of ‘63’ pepper was the smallest of 38.4 cm，the maximum amplitude of the ‘Jingcai’ pepper was 60.4 cm，the total chlorophyll content of ‘48’ was 62.23 mg/g，the total chlorophyll content of ‘121-7’ was 47.04 mg/g，the concentrations of intercellular CO2 of ‘70’ and ‘55’ pepper leaves were the highest of 514 μmol/mol and 513 μmol/mol respectively,‘Longjiao No.3’ leaf intercellular CO2 concentration decreased to the the lowest 391 μmol/mol，the net photosynthetic rate of pepper leaves was the highest in ‘70’ pepper，the net photosynthetic rate of pepper leaves was the lowest in ‘63’，‘60’ and ‘48’，which were between 0.34 and 0.70 μmol?m-2?s-1,the stomatal conductance of pepper leaves was the highest in ‘67’ peppers，the stomatal conductance of pepper leaves were the highest in ‘74’，‘60’，‘70’ peppers，between 51.4 and 498.0 mol?m-2?s-1，the transpiration rate of pepper leaves was the highest in ‘74’ and ‘67’，respectively 5.54 and 5.16 mmol?m-2?s-1，‘60’，‘62-6’ and ‘63’ pepper leaf transpiration rate were the lowest，respectively of 2.06，2.20，2.24 mmol?m-2?s-1.
