摘要:

【目的】测定相同栽培管理条件下赛蜜酥 1 号枣及其芽变赛蜜酥 2 号的表型特征及光合日变化的差异,为芽变选育提供参考依据。【方法】比较观测两者表型特征,采用 LI-6800 便携式光合仪测定两者的光合指标,分析叶片特征和光合参数的相关性。【结果】赛蜜酥 1 号和赛蜜酥 2 号的花期基本同步,花器结构之间具有显著差异,叶片特征只有叶片宽具有显著差异,叶片宽之间相差8.90 mm 左右,其它表型特征无明显差异,赛蜜酥 1 号的叶片为细长型,赛蜜酥 2 号叶片则为扁长型,两者枣吊长与枣吊粗之间具有显著差异,而单吊花量之间无显著差异。光合指标均有显著差异,且两者光合指标的日变化曲线基本一致,两者净光合速率(Pn)、蒸腾速率(Tr)和气孔导度(Gs)均为“双峰”曲线,“光合午休”现象明显,水分利用效率(WUE)的曲线均为大“V”型,且赛蜜酥 1 号的 WUE 高于赛蜜酥 2 号,两品种PnTrGsCiWUE等指标间分别相差2.60 μmol /(m2·s)、1.49 mmol /(m2·s)、0.07 mol /(m2·s)、8.04 μmol /(m2·s)、0.19 μmol /mmol。【结论】赛蜜酥 2 号的花和叶片均大于赛蜜酥 1 号,枣吊的生长势也强于赛蜜酥 1 号。赛蜜酥 2 号的净光合速率(Pn)、蒸腾速率(Tr)和气孔导度(Gs)均显著高于赛蜜酥 1 号,光合能力较强。

Abstract:

【Objective】 To determine the difference of phenotypic characteristics and diurnal variation of photosynthesis between Saimisu 1 and its budding Saimisu 2 under the same cultivation and management conditions in the hope of providing reference basis for bud breeding. 【Method】 In this experiment, the phenotypic characteristics of the two were observed and compared, the photosynthetic indexes of the two were measured by LI-6800 portable photosynthetic instrument, and then the correlation between leaf characteristics and photosynthetic parameters was analyzed. 【Results】 The flowering periods of Saimisu 1 and Saimisu 2 were basically synchronous, and there were significant differences in flower structure.Only the leaf width had significant differences, and the difference between leaf widths was about 8.90 mm.There was no significant difference in other phenotypic characteristics; It was found that the leaves of Saimisu 1 were slender, and the leaves of Saimisu 2 were flat and long.There was a significant difference between the hanging length and hanging thickness of jujube, but there was no significant difference between the amounts of single hanging flower; there were significant differences in photosynthetic indexes, and the diurnal variation curves of photosynthetic indexes of the two were basically identical.The net photosynthetic rate (Pn), transpiration rate (Tr) and stomatal conductance (Gs) of the two were "bimodal" curves.The phenomenon of "photosynthetic lunch break" was obvious, the curves of water use efficiency (WUE) were large "V", and the WUE of Saimisu 1 was higher than that of Saimisu 2; The differences of Pn, Tr, Gs, Ci and WUE between the two varieties were 2.60 respectively μmol /(m2·s), 1.49 mmol /(m2·s), 0.07 mol /(m2·s), 8.04 μmol /(m2·s) and 0.19 μmol /mmol. 【Conclusion】 Through comparison, it was found that the flowers and leaves of Saimisu 2 are larger than those of Saimisu 1, and so is the growth potential of jujube hanging.In addition, the net photosynthetic rate (Pn), transpiration rate (Tr) and stomatal conductance (Gs) of Saimisu 2 are significantly higher than those of Saimisu 1.
