摘要: 试验以野生辣椒威壮贝尔为砧木,辣椒品种科椒二号为接穗进行嫁接,研究了嫁接和自根辣椒对夏季温室中高温的抵御能力,为设施辣椒耐热栽培及生产提供依据。结果表明,高温对辣椒叶片各项指标影响比亚高温明显;不论是在高温还是亚高温条件下,嫁接辣椒叶片的脯氨酸(Pro) 含量、过氧化物酶(POD) 活性都明显高于自根苗,而嫁接苗的相对电导率、丙二醛(MDA) 含量、超氧阴离子产生速率低于自根苗。明确嫁接能显著提高辣椒的抗热性。

Abstract: In the study, we resarched the resistant capability of the grafted and self-rooted pepper to high temperature under greenhouse in summer conditions. The rootstock of the grafted pepper was wild pepper variety named Very Strong Bell, the scion and self-rooted pepper were both Kejiaoerhao. The results showed that the effect of high temperature on pepper leaves was more obvious than sub-high temperature. Both under high and sub-high temperature conditions, proline content and POD activity of the grafted pepper leaf were significantly higher than self-rooted, while the relative conductivity, MDA content and the production rate of Superoxide Anion of the grafted pepper were lower than self-rooted. These results highlight that grafting can significantly improve the heat resistance of pepper.

Key words: Pepper, Grafting, High temperature, Heat resistance
