Abstract

Abstract:

【Objective】 To probe into the differences of photosynthetic characteristics of different introduced Fraxinus in Yili area and analyze the effects of physiological and ecological factors in the hope of providing scientific basis for the introduction, breeding and regional cultivation of Fraxinus chinensis in this area.【Methods】 The diurnal changes of photosynthesis of eight introduced Fraxinus chinensis seedlings (Lula No.1, No.2, No.3, No.4, No.5, no.6, Red leaf Fraxinus and Fraxinus chinensis 'Aurea') under natural conditions in Yili area of Xinjiang were measured by li-6400xt photosynthetic apparatus. The relationship between different physiological ecological factors and photosynthetic characteristics was analyzed with Fraxinus macrophylla in the same year as control. 【Results】 The eight introduced varieties (lines) of Fraxinus chinensis showed better photosynthetic characteristics than those of Fraxinus rhynchophylla, and the net photosynthetic rate (Pn) of different varieties (lines) showed a single peak or double peak curve; PN of each variety (line) was affected by different physiological and ecological factors, among which stomatal conductance (Gs) was the most important factor, and was negatively correlated with intercellular dioxygen (Ci), and it was negatively correlated with PAR and RH (P<0.05) or extremely negatively correlated (P<0.01).【Conclusion】 The net photosynthetic rate (Pn), transpiration rate (Tr), water use efficiency (WUE) and local adaptability of the eight introduced Fraxinus chinensis seedlings are higher, and the introduction and domestication of Lula 3 and Lula 6 are the most successful.

Key words: introduction of Fraxinus spp; photosynthetic characteristics; physiological and ecological factors

摘要：

【目的】研究新疆伊犁地区不同引种白蜡光合特性的差异,分析生理生态因子对光合特性的影响,为伊犁地区优良白蜡引种和选育及区域化栽培提供科学依据。【方法】采用Li-6400XT光合仪,测定新疆伊犁地区自然条件下8种3年生引种白蜡(鲁蜡1号、2号、3号、4号、5号、6号、红叶白蜡、金叶白蜡)苗木的光合日变化,以相同年份大叶白蜡作为对照,分析不同生理生态因子与光合特性的关系。【结果】引进的8个白蜡品种除金叶白蜡外均表现出了比本地大叶白蜡更优的光合特性,不同品种净光合速率(Pn)呈单峰或双峰曲线;各品种Pn受不同生理生态因子影响,其中气孔导度(Gs)为大部分品种最主要的影响因子,与胞间二氧化碳浓度(Ci)负相关,与光合有效辐射(PAR)、相对湿度(RH)呈显著(P<0.05)或极显著相关(P<0.01)。【结论】8个引进白蜡品种均表现出了较好的光合特性,尤以鲁蜡3号、6号最佳,在伊犁地区的光合适应性最强。
