摘要/Abstract

摘要： 以‘卫士’（WS）、‘部野丁’（BYD）辣椒为砧木，以‘新丰2 号’（XF）辣椒为接穗进行
嫁接。以‘新丰2 号’自根嫁接辣椒为对照，研究了嫁接对辣椒的光合特性、产量和品质的影响。结果
表明：嫁接辣椒叶片的色素含量和净光合速率（Pn）多明显高于自根；‘卫士’为砧木（XF/WS）和‘部
野丁’为砧木（XF/BYD）的嫁接辣椒光补偿点分别为38.1 和50.9 μmo1 · m^-2 · s^-1，均低于自根对照，光
饱和点分别为981.0 和903.0 μmo1 · m^-2 · s^-1，均高于对照；嫁接与自根辣椒的表观量子效率（AQY）、CO2
补偿点和饱和点差异不显著，但XF/WS 的羧化效率（CE）显著高于对照；与对照相比，XF/WS 和XF/BYD
的产量分别提高了14.9%和8.5%，其果实的大小、形状、颜色及蛋白质、氨基酸、维生素C 和辣椒素含
量等变化不显著，XF/WS 的干物质与可溶性糖含量分别升高了7.1%和9.7%。‘卫士’和‘部野丁’作为
砧木具有较高的应用和推广价值。

Abstract: The photosynthetic characteristics，yield and quality in grafted（‘Xinfeng 2’scion grafted
onto‘Weishi’（XF/WS）and‘Buyeding’（XF/BYD）and own-root plants（‘Xinfeng 2’，the control）
of pepper were investigated. The results showed that the pigment content and net photosynthetic rate（Pn）
of grafted and own-root peppers were mostly higher in grafted leaves than in own-root leaves. The light
compensation point of XF/WS and XF/BYD were 38.1 and 50.9 μmo1 · m^-2 · s^-1 respectively，which lower
than that of the control. The light saturation point of XF/WS and XF/BYD were 981.0 and 903.0
μmo1 · m^-2 · s^-1 respectively，both higher than that of control significantly. No differences were found in
apparent quantum yield（AQY），CO2 compensation point and saturation point between grafted and
own-root plants. However XF/WS showed a markedly higher carboxylation efficiency（CE）than that of the control. In comparison with own-root pepper，the yield of XF/WS and XF/BYD increased by 14.9%
and 8.5% respectively，but no changes were observed in the fruit size，shape and color，and the contents of
protein，amino acid，vitamin C and capsaicine in fruits of grafted plants. The contents of dry matter and
soluble sugar in XF/WS fruits increased by 7.1% and 9.7% respectively compared with the control. These
data suggest that‘Weishi’and‘Buyeding’have higher values of application and popularization.
