摘要: 以4个不同氮效率基因型茄子为供试材料,采用营养液进行培养,研究了正常供氮和低氮胁迫下,茄子五叶期到八叶期的光合特性。结果表明,与正常供氮相比,低氮胁迫下,不同氮效率基因型茄子的光合速率(Pn)、叶片叶绿素相对含量(SPAD)和光系统Ⅱ的最大光化学效率(Fv/Fm)均较低,并表现先上升后下降趋势 与低氮高效及双低效基因型相比,氮双高效基因型具有较强的光合能力。

关键词: 茄子, 低氮胁迫, 氮效率, 光合特性

Abstract: Four nitrogen efficiency genotypes of eggplant were used to study the photosynthetic characteristics underthe nomgal and low nitrogen stress during the five leaves and eight leaves stages. The results showed that the photosynthet-is rate(Pn),chlorophyll relative content(SPAD)and the maximumphotochemistry efficiency(Fv/ Fm) under the low nitro-gen stress displayed a tendnrcy of rising first then decreasing. All the indexes above were remarkerbly lower than those un-der the normal nitrogen supply. Compared with other genotypes,the photosynthetic characteristics of the double-high nitro-gen efficiency genotype (which is high efficient under the normal and low nitrogen stress) are much better.

Key words: Egglant, Low nitrogen stress, Nitrogen use efficiency, Photosynthetic characteristics
