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50.9μmo1·m-2·s-1,均低于自根对照,光饱和点分别为981.0和903.0μmo1·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。
Rooted in ’Defender’ (WS) and ’BYD’ pepper, grafted with ’XF No. 2’ (XF) pepper. Taking ’Xinfeng No.2’ grafted with peppers as the control, the effects of grafting on photosynthetic characteristics, yield and quality of pepper were studied. The results showed that the pigment content and net photosynthetic rate (Pn) of grafted pepper were significantly higher than those of self-root; the grafted pepper light of ’Defender’ was rootstock (XF / WS) and ’Wild Ye Ding’ was rootstock (XF / BYD) The compensation points were 38.1 and 50.9μmo1 · m-2 · s-1, which were lower than that of the control and the light saturation points were 981.0 and 903.0μmo1 · m-2 · s-1, respectively. There was no significant difference in apparent quantum yield (AQY), CO2 compensation point and saturation point between root and pepper, but the carboxylation efficiency (CE) of XF / WS was significantly higher than that of the control. Compared with the control, XF / WS and XF / BYD The yield, the yield and the yield of XF / WS increased by 14.9% and 8.5%, respectively, but the changes of the size, shape, color and protein, amino acid, vitamin C and capsaicin did not change significantly. And 9.7%. ’Guardian’ and ’wild minder’ as rootstock has a high application and promotion value.
