【摘要】 以枸杞品种"宁杞1号"和"宁杞7号",以及枸杞品系‘1401’和‘1402’为试材,采用生长指标调查和光合特性测定等方法,研究了根域限制栽培模式下4个宁夏枸杞品种（系）的形态生长和光合指数差异,以探索根域限制栽培条件对不同枸杞品种（系）的形态生长和光合特性的影响。结果表明:‘1401’和‘1402’相对于其它2个品种生长指标较好,净光合速率（Pn）、胞间CO₂浓度（Ci）、蒸腾速率（Tr）、气孔导度（Gs）等光合生理参数也均高于"宁杞7号"和"宁杞1号",但‘1401’的相对叶绿素含量（SPAD）和水分利用效率（WUE）相对最低。综合分析认为枸杞优良品系‘1402’更适合根域限制栽培条件。更多还原

【Abstract】 Taking wolfberry cultivars ‘Ningqi No.1’ and ‘Ningqi No.7’,wolfberry strains ‘1401’ and‘1402’ as the test materials.The methods of growth index investigation and photosynthetic characteristics determination were used to analysis the differences of plant growth and photosynthetic characteristics of four Lycium barbarum L.cultivars（strains）under the root-limited cultivation.In order to explore the morphological growth and photosynthetic characteristics of different Lycium barbarum L. cultivars（strains） in root-limited cultivation.The results showed that ‘1401’ and ‘1402’ had better growth indexes relative to the other two cultivars ‘Ningqi No.1’‘Ningqi No.7’.The net photosynthetic rate（Pn）,intercellular CO₂ concentration（Ci）,transpiration rate（Tr）,stomatal conductance（Gs） were higher than ‘Ningqi No.1’ and ‘Ningqi No.7’.The SPAD and water use efficiency（WUE） of ‘1401’ were the lowest.Through comprehensive analysis, it is concluded that ‘1402’ is more suitable for the root-limited cultivation.更多还原
