以赤茄(Solanum integrifolium)和栽培品种远缘杂交选育得到的核质互作型雄性不育系05-506及其保持系05-507为材料,测定并分析了叶片激素、叶绿素、游离总氨基酸、可溶性糖含量及光合特性。结果表明,茄子不育系苗期叶片中IAA和GA3含量低于保持系,ZR含量高于保持系,ABA/(IAA+ZR+GA3)比值约为保持系的1.3倍;不育系叶绿素含量幼苗期低于保持系,盛花期和保持系相近,结果期高于保持系;可溶性糖和游离总氨基酸含量高低随光合速率的变化而变化,幼苗期C/N比值低,盛花期C/N比值增大,碳水化合物代谢加强,结果期C/N比值下降,但不育系下降幅度较保持系少。不育系与保持系的Pn日变化均呈双峰曲线,即有光合“午休”现象;Pn值顺序不育系为幼苗期<盛花期<结果期,保持系为幼苗期<结果期<盛花期;不育系在营养生长和生殖生长时期的光饱和点均高于保持系,光补偿点在幼苗期和盛花期高于保持系,但结果期比保持系低。 The cytoplasmic male sterile line 05-506 and its maintainer line 05-507, derived from distant hybridization of Solanum integrifolium and cultivars, were used as materials to measure and analyze the effects of leaf hormone, chlorophyll, free total Amino acids, soluble sugar content and photosynthetic characteristics. The results showed that the content of IAA and GA3 in the leaves of the eggplant sterile line was lower than that of the maintainer line, and the ratio of ABA / (IAA + ZR + GA3) was about 1.3 times that of the maintainer line. The chlorophyll content The seedling stage was lower than the maintainer line, the flowering stage and the maintainer line were similar, and the fruiting stage was higher than the maintainer line. The content of soluble sugar and total free amino acids changed with the photosynthesis rate, the C / N ratio was low at seedling stage, C / N The ratio increased, carbohydrate metabolism strengthened, and the C / N ratio decreased in the end of the experiment, but the decline of CMS was less than that of maintainer lines. The diurnal variation of Pn in both CMS and maintainer lines showed a double-peak curve, that is, there was photosynthesis “lunch break ” phenomenon. The Pn value CMS was seedling stage
